  • Does Google hire .NET developers? [closed]

    - by Hermann
    I am a .NET developer looking for a job. I've talked to someone who works at Google and loves it there and I generally have a good feeling about working for that company because I love most of Google's products and services. But are they even interested in .NET developers? I had the impression they only use non-proprietary technologies.

  • How many programming jobs are there that require German/French language ?

    - by HJ-INCPP
    Hello, I want to improve my chances getting a job (entry-level:programming) by learning another language. How many jobs that require exclusively French, German, English are there ? Which is better to learn (more/better jobs): French or German ? Is it worth it (or should I learn another programming language instead :D) ? Thank you. P.S I live in Romania, I (think I) know English

  • As a programmer, what are some telltale signs that you're about to get fired or laid off?

    - by plaureano
    If you have ever been fired from a job, did you notice anything different about the behavior of your peers or upper management just before your termination? What are some common signs to look for among your coworkers and project manager(s) that would indicate your position is severely at risk? EDIT: My instincts were right, and I opted to resign rather than face termination. I guess when you have that "gut feeling" that something is about to happen, it's a strong sign that you should be heading for the exit...

  • How to count the number of listitems in an asp.bulletedlist with JavaScript

    - by Andy5
    Hi I have an asp:bulletedlist control, which sits inside a div tag, and I need to count the number of list items inside the control. Searching the internet, and noting the fact the html given back by the items is a list i.e. <li>, I thought I could use an example of: var listcontrol = document.getElementById('BulletedList1'); var countItems = listcontrol.getElementByTagName('li').length; However, when I do this, it throws and error saying that no object exists for this control. So, my problem is, and because I must do this clientside because I want to use this to set the height of the div tag, is how do you count the number of items inside a asp:bulletedlist control with javascript?

  • Using Read-Only Fields in a C# WebBrowser

    - by TheDramaLlama
    I'm currently using a WebBrowser control in a C# WinForms application, and attempting to control some variability presented with this control. Basically, my users log in to a separate UI provided by my application, which then displays the WebBrowser control, navigates to a predetermined log-in URL, and then auto-fills the username and password fields on that page. However, in order to prevent unpredictable behavior in this WebBrowser control, I want to make these username and password text boxes read-only after they are auto-populated. Essentially, I want the user to see a browser page that has been filled out for them, and that cannot be edited. (This is so that any authentication errors can be handled by my application as opposed to the browser.) The code I'm currently using to populate the text fields and make them read only is as follows: webBrowser1.Document.GetElementById("username").InnerText = username; webBrowser1.Document.GetElementById("password").InnerText = password; webBrowser1.Document.GetElementById("username").Enabled = false; webBrowser1.Document.GetElementById("password").Enabled = false; Unfortunately, when I try to make the fields read-only, the authentication server acts like the password field was not filled out, and prompts the user to fill it out again after the "Submit" button is clicked. Is this expected behavior, and if so, what other methods can I try to prevent users from changing the credentials that the browser was auto-populated with?

  • Online job-searching is tedious. Help me automate it.

    - by ehsanul
    Many job sites have broken searches that don't let you narrow down jobs by experience level. Even when they do, it's usually wrong. This requires you to wade through hundreds of postings that you can't apply for before finding a relevant one, quite tedious. Since I'd rather focus on writing cover letters etc., I want to write a program to look through a large number of postings, and save the URLs of just those jobs that don't require years of experience. I don't require help writing the scraper to get the html bodies of possibly relevant job posts. The issue is accurately detecting the level of experience required for the job. This should not be too difficult as job posts are usually very explicit about this ("must have 5 years experience in..."), but there may be some issues with overly simple solutions. In my case, I'm looking for entry-level positions. Often they don't say "entry-level", but inclusion of the words probably means the job should be saved. Next, I can safely exclude a job the says it requires "5 years" of experience in whatever, so a regex like /\d\syears/ seems reasonable to exclude jobs. But then, I realized some jobs say they'll take 0-2 years of experience, matches the exclusion regex but is clearly a job I want to take a look at. Hmmm, I can handle that with another regex. But some say "less than 2 years" or "fewer than 2 years". Can handle that too, but it makes me wonder what other patterns I'm not thinking of, and possibly excluding many jobs. That's what brings me here, to find a better way to do this than regexes, if there is one. I'd like to minimize the false negative rate and save all the jobs that seem like they might not require many years of experience. Does excluding anything that matches /[3-9]\syears|1\d\syears/ seem reasonable? Or is there a better way? Training a bayesian filter maybe?

  • An Unusual UpdatePanel

    - by João Angelo
    The code you are about to see was mostly to prove a point, to myself, and probably has limited applicability. Nonetheless, in the remote possibility this is useful to someone here it goes… So this is a control that acts like a normal UpdatePanel where all child controls are registered as postback triggers except for a single control specified by the TriggerControlID property. You could basically achieve the same thing by registering all controls as postback triggers in the regular UpdatePanel. However with this, that process is performed automatically. Finally, here is the code: public sealed class SingleAsyncTriggerUpdatePanel : WebControl, INamingContainer { public string TriggerControlID { get; set; } [TemplateInstance(TemplateInstance.Single)] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate ContentTemplate { get; set; } public override ControlCollection Controls { get { this.EnsureChildControls(); return base.Controls; } } protected override void CreateChildControls() { if (string.IsNullOrWhiteSpace(this.TriggerControlID)) throw new InvalidOperationException( "The TriggerControlId property must be set."); this.Controls.Clear(); var updatePanel = new UpdatePanel() { ID = string.Concat(this.ID, "InnerUpdatePanel"), ChildrenAsTriggers = false, UpdateMode = UpdatePanelUpdateMode.Conditional, ContentTemplate = this.ContentTemplate }; updatePanel.Triggers.Add(new SingleControlAsyncUpdatePanelTrigger { ControlID = this.TriggerControlID }); this.Controls.Add(updatePanel); } } internal sealed class SingleControlAsyncUpdatePanelTrigger : UpdatePanelControlTrigger { private Control target; private ScriptManager scriptManager; public Control Target { get { if (this.target == null) { this.target = this.FindTargetControl(true); } return this.target; } } public ScriptManager ScriptManager { get { if (this.scriptManager == null) { var page = base.Owner.Page; if (page != null) { this.scriptManager = ScriptManager.GetCurrent(page); } } return this.scriptManager; } } protected override bool HasTriggered() { string asyncPostBackSourceElementID = this.ScriptManager.AsyncPostBackSourceElementID; if (asyncPostBackSourceElementID == this.Target.UniqueID) return true; return asyncPostBackSourceElementID.StartsWith( string.Concat(this.target.UniqueID, "$"), StringComparison.Ordinal); } protected override void Initialize() { base.Initialize(); foreach (Control control in FlattenControlHierarchy(this.Owner.Controls)) { if (control == this.Target) continue; bool isApplicableControl = false; isApplicableControl |= control is INamingContainer; isApplicableControl |= control is IPostBackDataHandler; isApplicableControl |= control is IPostBackEventHandler; if (isApplicableControl) { this.ScriptManager.RegisterPostBackControl(control); } } } private static IEnumerable<Control> FlattenControlHierarchy( ControlCollection collection) { foreach (Control control in collection) { yield return control; if (control.Controls.Count > 0) { foreach (Control child in FlattenControlHierarchy(control.Controls)) { yield return child; } } } } } You can use it like this, meaning that only the B2 button will trigger an async postback: <cc:SingleAsyncTriggerUpdatePanel ID="Test" runat="server" TriggerControlID="B2"> <ContentTemplate> <asp:Button ID="B1" Text="B1" runat="server" OnClick="Button_Click" /> <asp:Button ID="B2" Text="B2" runat="server" OnClick="Button_Click" /> <asp:Button ID="B3" Text="B3" runat="server" OnClick="Button_Click" /> <asp:Label ID="LInner" Text="LInner" runat="server" /> </ContentTemplate> </cc:SingleAsyncTriggerUpdatePanel>

  • Configure Mouse Buttons for "Administrator"/Elevated privileges

    - by Zhaph - Ben Duguid
    I am, for better or worse, an administrator on my Windows 7 machine. However, even then, I still need to run certain programs "as Administrator" - for example, Visual Studio 2008 when working with local IIS sites. I also like to have the extra buttons on my IntelliMouse Optical doing non-standard things, like representing Ctrl and Shift. However, when in VS running as administrator, these settings aren't picked up, just like my mapped drives aren't picked up - I would understand this if I was logging in as a different user, supplying credentials, etc, but I'm not, I'm just pressing "Yes" at the UAC prompt. Normally, I'd just right click the item in the start menu and select "Run as administrator", but that's not an option on the context menu for either the Microsoft IntelliPoint Mouse application that appears under "Programs", nor the "Mouse" control panel item. Running the control panel as administrator also doesn't seem to help. So has any one got any suggestions on how I can configure my mouse buttons for the elevated version of me that Visual Studio is running as?

  • Tracking changes to firewall configs?

    - by jmreicha
    Myself and one other indivdual will be taking over some of the daily firewall management duties soon and I'm looking for a way to track changes on our firewall configurations for auditing purposes and need some ideas on a good way to track changes the changes that are made. I don't have a lot of specific criteria but here are some of the basic things I would like to be able to do: Access to previous revisions of firewall configs Access to changes made and by whom When specific changes were made I'm wondering if some sort of revision control software would work here as a way to track the the changes? Or if some other approach would work better for managing the change control in this situation. I'm open to any and all suggestions at this point. EDIT: We are using a Checkpoint pair, one passive one active configuration. I will update again with specific model numbers when I get a chance.

  • Using LDAP Attributes to improve performance for large directories

    - by Vineet Bhatia
    We have a LDAP directory with more than 50,000 users in it. LDAP Vendor suggests maximum limit of 40,000 users per LDAP group. We have number of inactive users and those are being purged but what if we don't get below the 40,000 users? Would switching to using multivalued attribute at user record level instead of using LDAP groups yield better performance during authentication, adding new users, etc? I know most server software (portal, application servers, etc) use LDAP groups. But, we have a standardized web service interface for access control instead of relying on server software to map LDAP groups to security roles. Each application uses this common "access control web service". Security roles are used within application to build fine-grained ACL used within each enterprise application.

  • Website deployment - managing uploaded content?

    - by Legion
    I'm a programmer by trade, "server administrator" by company necessity. We're looking at dumping the old painful "update site by FTP upload" style of deployment. Having the webserver check out the latest code base from version control into a folder and having a "current" symlink point to the latest checkout (allowing for easily stepping back to an older version by changing the symlink) seems to be the way we want to go. But I have a question: what's a good practice for dealing with user-uploaded content? This stuff isn't in version control. I have a couple of ideas for dealing with this, but what is the smart, accepted practice?

  • Control copy/paste doesn't work

    - by Guest
    I have a laptop HP PAVILION dv6-3126er with Windows 7 Home Edition installed and neither control copy nor control paste doesn't work (i've tried: ctrl+c, ctrl+v, shift+c, shift+v, ctrl + insert, shift + insert). I've tried to run a system check through cmd with sfc /scannow, it repaired something, i restarted but it didn't solve the problem. I've also tried many key combinations (like alt+ctrl+fn), but nothing works in any program. In Microsoft Word 2003 in the menu i have no key combination for copy/paste near them (in my previous comp they've been there - in brackets). Shift+Delete works by the way. I brought this laptop a few weeks ago, and i discovered this problem in the first days. I have no viruses because i have had no time to even connect him to internet. Anyways, i checked it for viruses - it is clean. I don't want to do system restore, because i see no reason to do it for a pretty clean system. I hope it is not a problem with the laptop itself. Maybe there is another reason? Maybe i need to do some more system checks? Any suggestions? Thanks in advance.

  • Is there a word processor similar to MS Word which saves files as readable txt files?

    - by zenbomb
    I'm writing a paper together with my supervisor and would like to have a more sophisticated version control than *_291112_NEW_NEW_revised1.doc files. My supervisor is a non-computer person will never ever use LaTeX or git and loves MS Word. I'm therefore looking for an alternative to Word (I need commenting on text passages!) which stores the files as clean text (Markup for formating is fine), so I'm able to put them under version control on my side. I'm aware that git can also handle binary files, but I'd prefer the cleaner way of looking at the contents directly. If there's a way to automatically extract the text from word files, I'm fine with that too for now.

  • Clearing C#'s WebBrowser control's cookies for all sites WITHOUT clearing for IE itself

    - by Helgi Hrafn Gunnarsson
    Hail StackOverflow! The short version of what I'm trying to do is in the title. Here's the long version. I have a bit of a complex problem which I'm sure I will receive a lot of guesses as a response to. In order to keep the well-intended but unfortunately useless guesses to a minimum, let me first mention that the solution to this problem is not simple, so simple suggestions will unfortunately not help at all, even though I appreciate the effort. C#'s WebBrowser component is fundamentally IE itself so solutions with any sorts of caveats will almost certainly not work. I need to do exactly what I'm trying to do, and even a seemingly minor caveat will defeat the purpose completely. At the risk of sounding arrogant, I need assistance from someone who really has in-depth knowledge about C#'s WebBrowser and/or WinInet and/or how to communicate with Windows's underlying system from C#... or how to encapsulate C++ code in C#. That said, I don't expect anyone to do this for me, and I've found some promising hints which are explained later in this question. But first... what I'm trying to achieve is this. I have a Windows.Forms component which contains a WebBrowser control. This control needs to: Clear ALL cookies for ALL websites. Visit several websites, one after another, and record cookies and handle them correctly. This part works fine already so I don't have any problems with this. Rinse and repeat... theoretically forever. Now, here's the real problem. I need to clear all those cookies (for any and all sites), but only for the WebBrowser control itself and NOT the cookies which IE proper uses. What's fundamentally wrong with this approach is of course the fact that C#'s WebBrowser control is IE. But I'm a stubborn young man and I insist on it being possible, or else! ;) Here's where I'm stuck at the moment. It is quite simply impossible to clear all cookies for the WebBrowser control programmatically through C# alone. One must use DllImport and all the crazy stuff that comes with it. This chunk works fine for that purpose: [DllImport("wininet.dll", SetLastError = true)] private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength); And then, in the function that actually does the clearing of the cookies: InternetSetOption(IntPtr.Zero, INTERNET_OPTION_END_BROWSER_SESSION, IntPtr.Zero, 0); Then all the cookies get cleared and as such, I'm happy. The program works exactly as intended, aside from the fact that it also clears IE's cookies, which must not be allowed to happen. The problem is that this also clears the cookies for IE proper, and I can't have that happen. From one fellow StackOverflower (if that's a word), Sheng Jiang proposed this to a different problem in a comment, but didn't elaborate further: "If you want to isolate your application's cookies you need to override the Cache directory registry setting via IDocHostUIHandler2::GetOverrideKeyPath" I've looked around the internet for IDocHostUIHandler2 and GetOverrideKeyPath, but I've got no idea of how to use them from C# to isolate cookies to my WebBrowser control. My experience with the Windows registry is limited to RegEdit (so I understand that it's a tree structure with different data types but that's about it... I have no in-depth knowledge of the registry's relationship with IE, for example). Here's what I dug up on MSDN: IDocHostUIHandler2 docs: http://msdn.microsoft.com/en-us/library/aa753275%28VS.85%29.aspx GetOverrideKeyPath docs: http://msdn.microsoft.com/en-us/library/aa753274%28VS.85%29.aspx I think I know roughly what these things do, I just don't know how to use them. So, I guess that's it! Any help is greatly appreciated.

  • How can I bind the nested viewmodels to properties of a control

    - by Robert
    I used Microsoft's Chart Control of the WPF toolkit to write my own chart control. I blogged about it here. My Chart control stacks the yaxes in the chart on top of each other. As you can read in the article this all works quite well. Now I want to create a viewmodel that controls the data and axes in the chart. So far I'm able to add axes to the chart and show them in the chart. But I have a problem when I try to add the lineseries because it has one DependentAxis and one InDependentAxis property. I don't know how to assign the proper xAxis and yAxis controls to it. Below you see part of the LineSeriesViewModel. It has a nested XAxisViewModel and YAxisViewModel property. public class LineSeriesViewModel : ViewModelBase, IChartComponent { XAxisViewModel _xAxis; public XAxisViewModel XAxis { get { return _xAxis; } set { _xAxis = value; RaisePropertyChanged(() => XAxis); } } //The YAxis Property look the same } The viewmodels all have their own datatemplate. The xaml code looks like this: <UserControl.Resources> <DataTemplate x:Key="xAxisTemplate" DataType="{x:Type l:YAxisViewModel}"> <chart:LinearAxis x:Name="yAxis" Orientation="Y" Location="Left" Minimum="0" Maximum="10" IsHitTestVisible="False" Width="50" /> </DataTemplate> <DataTemplate x:Key="yAxisTemplate" DataType="{x:Type l:XAxisViewModel}"> <chart:LinearAxis x:Name="xAxis" Orientation="X" Location="Bottom" Minimum="0" Maximum="100" IsHitTestVisible="False" Height="50" /> </DataTemplate> <DataTemplate DataType="{x:Type l:LineSeriesViewModel}"> <!--Binding doesn't work on the Dependent and IndependentAxis! --> <!--YAxis XAxis and Series are properties of the LineSeriesViewModel --> <l:FastLineSeries DependentAxis="{Binding Path=YAxis}" IndependentAxis="{Binding Path=XAxis}" ItemsSource="{Binding Path=Series}"/> </DataTemplate> <Style TargetType="ItemsControl"> <Setter Property="ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <!--My stacked chart control --> <l:StackedPanel x:Name="stackedPanel" Width="Auto" Height="Auto" Background="LightBlue"> </l:StackedPanel> </ItemsPanelTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ClipToBounds="True"> <!-- View is an ObservableCollection of all axes and series--> <ItemsControl x:Name="chartItems" ItemsSource="{Binding Path=View}" Focusable="False"> </ItemsControl> </Grid> This code works quite well. When I add axes they get drawn. But the DependentAxis and InDependentAxis of the lineseries control stay null, so the series doesn't get drawn. How can I bind the nested viewmodels to the properties of a control?

  • Update Panel error: Control with the ID "xxx" could not be found in the UpdatePanel

    - by George
    I have a composite drop down calendar user control that consists of a textbox and and calendar image and a validation control. I expose a property called "TextBox" on the usercontrol which returns a reference to the textbox used within the control. This is the textbox that the user enters the date into. In the ASPX page, I have an instance of this usercontrol: <uc1:DropDownCalendar ID="dtmDateFirstEntry" runat="server" Required="True" /> In my code behind, I want to detect when a user has tabbed off of the textbox and, using an UpdatePanel, referesh an appropriate message depending on the date that was specified. Elsewhere in the ASPX page I have this: <asp:UpdatePanel ID="upIntendedStay" runat="server"> <ContentTemplate> <asp:Label ID="Label4" runat="server" Text="Update this text from server" CssClass="ErrorText"></asp:Label> </ContentTemplate> </asp:UpdatePanel> Here's what I do in the code behind: If Not Me.IsPostBack Then dtmDateFirstEntry.TextBox.AutoPostBack = True Dim trigger As New AsyncPostBackTrigger trigger.ControlID = dtmDateFirstEntry.TextBox.ClientID trigger.EventName = "onChange" upIntendedStay.Triggers.Add(trigger) End If When the page runs and I view the source, I see something like this: <input id="ctl00_phPageContent_dtmDateFirstEntry_txtDate" class="DefaultTextBox" name="ctl00$phPageContent$dtmDateFirstEntry$txtDate" onchange="javascript:setTimeout('__doPostBack(\'ctl00$phPageContent$dtmDateFirstEntry$txtDate\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" style="width: 112px;" type="text" value="Mar-29-2010" /> <input id="ctl00_phPageContent_dtmDateFirstEntry_imgDate" name="ctl00$phPageContent$dtmDateFirstEntry$imgDate" src="images/calendar.JPG" style="border-width: 0px;" type="image" />&nbsp; When I run it, I get this error: A control with ID 'ctl00_phPageContent_dtmDateFirstEntry_txtDate' could not be found for the trigger in UpdatePanel 'upIntendedStay'. I didn't think that the trigger control had to be within the UpdatePanel. I thought that was the whole point of adding the trigger. How do I refresh this update panel changes to the text in the date usercontrol. Next I will have to add other triggers to trigger the refreshing of the Update Panel from other controls scattered across the page, so clearly all of the trigger sources cannot be within the UpdatePanel.

  • Adding ComboBoxItem to a combobox inside a user control (XAML/WPF)

    - by byte
    I am currently learning to create custom controls in WPF. I successfully created a simple custom control using a Label and a Text Box. I was able to allow setting the Label text by DependencyProperty. Now I am creating a user control that has a ComboBox. I need to allow adding items to this ComboBox from outside the control. To achieve this, I tried exposing a DependencyProperty of type ItemsCollection and it will allows access to the ComboBox's Items property (the DP in my control sample is named 'CbItems'). But I get errors because Items property of Combobox is ReadOnly. Control XAML <UserControl x:Class="MyWpfApp.Controls.MyControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="Auto" Width="Auto"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> <Label Grid.Column="0" Content="{Binding FieldLabel}"></Label> <ComboBox Name="cmb" Grid.Column="1" Width="150"></ComboBox> </Grid> </UserControl> MainWindow XAML <Window x:Class="MyWpfApp.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ctl="clr-namespace:MyWpfApp.Controls" Title="Window1" Height="300" Width="300"> <Grid> <ctl:MyControl> <ctl:MyControl.CbItems> <ComboBoxItem>Hello</ComboBoxItem> <ComboBoxItem>World</ComboBoxItem> <ComboBoxItem>Hi</ComboBoxItem> </ctl:LobCombox.CbItems> </ctl:LobCombox> </Grid> </Window> I would like to know what the correct way is to achieve this functionality. I believe the answer to this might also help with other controls like GridView etc Many Thanks

  • Swiping Images with Page Control in Iphone

    - by lakesh
    I am trying to make practice app where i can scroll images with page control. I am able to scroll images and able to include the page control. But the problem i face is i am not able to interlink the two. Meaning to say when I scroll the images, the page control is not affected and when i change the page control, the scrolling of the images is unaffected. I have referred to this: http://www.iosdevnotes.com/2011/03/uiscrollview-paging/ for the scrolling with page control.

  • Giving event control back to xaml/callee to access check/uncheck

    - by dovholuk
    Hi All, I've scoured the Internet but my search-foo must not work if it's out there cause I just can't find the proper search terms to get me the answer I am looking for. So I turn to the experts here as a last resort to point me in the right direction. What I'm trying to do is create a composite control of a text box and a list box but I want to allow the control consumer to decide what to do when say the checkbox is checked/unchecked and I just can't figure it out... Maybe i'm going about it all wrong. What I've done thus far is to: create a custom control that extends ListBox expose a custom DP named "Text" (for the Text box but it's not the important part) craft the generic.xaml so that the list items have a default ItemTemplate/DataTemplate inside the DataTemplate I'm trying to set the "Checked" or "Unchecked" events expose 'wrapper' events as DPs in the custom control that would get 'set' via the template when instatiated As soon as I try something like the following (inside generic.xaml): <DataTemplate> <...> <CheckBox Checked="{TemplateBinding MyCheckedDP}"/> <...> </DataTemplate> I get runtime exceptions, the designer - vs2010 - pukes out a LONG list of errors that are all very similar and nothing I do can make it work. I went so far as to try using the VisualTreeHelper but no magic combination I could find would work nor would it allow me to traverse the tree because when the OnApplyTemplate method fires the listbox items don't exist yet and aren't in the tree. So hopefully this all makes sense but if not please let me know and I'll edit the post for clarifications. Thanks to all for any pointers or thoughts... Like I said maybe I'm heading about it in the wrong way from the start... EDIT (Request for xaml) generic.xaml datatemplate: <DataTemplate > <StackPanel Orientation="Horizontal" > <local:FilterCheckbox x:Name="chk"> <TextBlock Text="{Binding Path=Display}" /> </local:FilterCheckbox> </StackPanel> </DataTemplate> usercontrol.xaml (invocation of custom control) <local:MyControl FancyName="This is the fancy name" ItemChecked="DoThisWhenACheckboxIsChecked" <-- this is where the consumer "ties" to the checkbox events ItemsSource="{Binding Source={StaticResource someDataSource}}" />
