  • How Can I Add a New Command to a Control's Event

    - by Chris
    Hi, thanks for taking a look at this question. I have been building an application (VB/WPF) following Josh Smith's example of an MVVM pattern: Click here to view My Views have Controls which trigger a Command upon an event, such as a button click and these are bound to properties in the ViewModel. My ViewModel exposes properties of type ICommand which invoke the appropriate methods. This has worked well, until now! I now want to use a Thumb Control to allow a user to move an object within a Canvas. I don't believe that the Thumb has a Command capability 'out of the box'. A Thumb raises a 'DragDelta' event when being moved. So my question is as follows: How do I extend a Control's capability to issue a Command upon an event please? I wish to issue a new Command, let's say 'onDragDelta' so that I can bind it to a property in my ViewModel just like my Buttons. Thank you very much

  • ASP.NET ReportViewer Control Fonts to Century Gothic

    - by sajoshi
    We are using ASP.NET ReportViewer Control to render rdl files. In the rdl files we have set the font to “Century Gothic” and in preview mode it renders the fonts nicely. However – when it gets rendered on browser we see the fonts defaulted to “Times New Roman”. I tried couple of things without success: 1. Setting the font family of the page () 2. Setting the FontNames of the ReportViewer control Please let me know how we can render the fonts to Century Gothic. One more thing is I don't see Century Gothic in the list of available fonts in the HTML Editor inside Visual Studio 2010. Do I need to add them somewhere?

    - by poojad
    I have a aspx page which contains a User Control uc1 ans within uc1, there is another user control uc2. Now I need to call a javascript function in the uc2's page load.

(load is the javascript function in uc2) Can anyone help me out with this? Thank you.

  • ToolTip for a User Control Issue

    - by Gaddigesh
    I have a control inherited from usercontrol, I have implemented it such a way that it acts as XY Plane and displays curves. When user clicks and holds the mouse down for 1 sec i trigger SetToolTip to display tooltip indicationg (x,y) coordinates. Tooltip remains even on drag updating x,y positions System.Windows.Forms.ToolTip myToolTip = new System.Windows.Forms.ToolTip(); myToolTip.SetToolTip(myControl,"x= val,y=val"); It is working fine But Tooltip stops showing after (1)I play around for sometime(click,drag repeatedly) and will never show up (2)I move some other window on this control(this happens sporadically) what could be the problem???

  • How to customize tooltip for silverlight control?

    - by KentZhou
    SL provide ToolTipService.ToolTip for simple tooltip. I want to customize tooltip with my own user control. One way is to do something like: <TextBlock Text="Hello" > <ToolTipService.ToolTip> <TextBlock Text="I can help you." /> <!--replace this with user control --> </ToolTipService.ToolTip> </TextBlock> But what I want is: 1) create a style for tooltip, so that it can be set as something like <TextBlock Text="Hello" Style="{StaticResource TextBlockWithToolTip}" > 2) Content for tooltip can be set dynamically from datacontext, such as title, content, etc. How to implement it?

  • Accessing WPF Template for Custom Control from Code behind

    - by Ashwani Mehlem
    Hi, i am trying to access a named grid inside a default template for a custom control from code behind. But it seems that the template for the control is null, even after calling ApplyTemplate(). Is that impossible inside the controls constuctor? Here's the code: Generic.xaml: ... <ControlTemplate TargetType="{x:Type local:TimeTableControl}"> <Grid Name="ContentGrid"> </Grid> </ControlTemplate> ... TimeTableControl.cs: public TimeTableControl() { ApplyTemplate(); contentGrid = (Grid)(Template.FindName("ContentGrid", this)); //Line above causes null-pointer-exception ... }

  • Adding Images to an ASP .Net Chart Control

    - by wali
    Hello all! I'm not sure if I titled the question correctly so it would be better if I explained what I'm trying to do. I am using the ASP .Net Chart Control to create a line chart showing numbers of trouble calls based on date. What I would like to do is implement a way of annotating the chart with data whereas if there was a spike in trouble calls a line, or asterisk, etc would direct the viewer to "read notes below for an explanation for why the numbers spiked here". From the samples for the chart control there is a way you can add a bitmap to the chart, however I don't see how that will be effective here because the explanations will come dynamically from a database. If anyone's done something like this or has some guidance I'd appreciate it. Thanks!

  • Menu Control in Master Page fails to use CSS styles

    - by Shaun
    I'm working on a web application that uses ASP.NET 3.5 and C#. Structurally, I have a master page with a menu control on it. The control serves as my navigation, and it gets its items from a SiteMapDataSource control and a corresponding Web.sitemap file. The problem is that some styles do not render properly when you specify the CssClass property. More specifically, the selected and hover styles don't respond to css styles. Consider the code below: <%@ Master Language="C#" AutoEventWireup="true" CodeFile="Site.master.cs" Inherits="Site" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.or/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>A webpage</title> </head> <body> <form id="form1" runat="server"> <div id="page"> <asp:Menu ID="navMenu" Orientation="Horizontal" StaticMenuStyle-CssClass="staticMenu" StaticMenuItemStyle-CssClass="staticMenuItem" StaticSelectedStyle-CssClass="staticSelectedItem" StaticHoverStyle-CssClass="staticHoverItem" runat="server"> </asp:Menu> <asp:SiteMapDataSource ID="srcSiteMap" runat="server" ShowStartingNode="false" /> <br /> <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> </form> </body> </html> Suppose I had a corresponding .css file with the following: .staticMenuItem { background-color:Red; } .staticSelectedItem { background-color:Green; } .staticHoverItem { background-color:Blue; } What will happen is that my item backgrounds will properly be red, but my selected item will not be green and the item I'm hovering my mouse over will not be blue. This seems true regardless of whether or not I include the style in the head of the master page or in an external file in default theme as specified in the web.config file. If I specify the styles in the asp.net xml like so: <asp:Menu ID="navMenu" Orientation="Horizontal" runat="server"> <StaticSelectedStyle BackColor="Green" Font-Underline="True" Font-Bold="True" /> <StaticHoverStyle BackColor="Gray" /> </asp:Menu> It appears to work properly in Firefox, but the style is never embedded in the html in Internet Explorer. Odd. Does anybody have any insight into what is causing this problem and how to neatly work around it? I'm aware I might be able to programmically determine the current page and select the corresponding menu item manually so it receives the proper style class, but before I resort to hacking C# and Javascript together to fix this functionality, I'm open to ideas.

  • BackgroundWorker and WebBrowser Control

    - by James Jeffery
    Is it possible/recommended to use background worker threads with the web browser control? I am creating a bot that searches google for keywords, then checks for sites in the first 10 pages to see if a site is ranked. The user can provide a maximum of 20 sites to check, and can use proxies. So ideally I'd like to have 5 threads working at once. Is it possible? I might have heard somewhere that there are problems with WebBrowser control and threads.

  • Designing a WPF map control.

    - by Dylan
    I'm thinking about making a simple map control in WPF, and am thinking about the design of the basic map interface and am wondering if anyone has some good advice for this. What I'm thinking of is using a ScrollViewer (sans scroll bars) as my "view port" and then stacking everything up on top of a canvas. From Z-Index=0 up, I'm thinking: Base canvas for lat/long calculations, control positioning, Z-Index stacking. Multiple Grid elements to represent the maps at different zoom levels. Using a grid to make tiling easier. Map objects with positional data. Map controls (zoom slider, overview, etc). Scroll viewer with mouse move events for panning and zooming. Any comments suggestions on how I should be building this?

  • c# control location precision

    - by AC
    I need more precision then integer based locations when puttng controls on a form. It seems control.location only supports Point. Is there a work around for this? Point p = new Point(100, 200); this.Location = p;// this works of course PointF pF = new PointF(100.04f, 200.08f); this.Location = pF;// this does not work of course because Location expects a Point not PointF Is there some setting on the base form, or base control I can set to have more location precision?

  • Visual Studio 2008 - formatting/control characters/marks

    - by AL
    Hi, I don't know what I did but somehow the IDE has started displaying a green dot whenever I press spacebar and a green arrowhead whenever I press TAB. The source has become littered with these characters all over and I am finding it very difficult to code in the presence of so many formatting marks. I have tried to search a solution on Google but couldn't perhaps enter the right keywords so haven't been able to fix the behavior. Is there any way I can stop VS2008 IDE from littering my source code with these green dots and arrowheads whenever I press spacebar/tab? I would be really thankful for this help. Thanks, -AL PS: Re-posting the question as I am new to this forum and probably couldn't see the email notification option earlier. My apologies for this inconvenience.

  • Accessing Textboxes in Repeater Control

    - by CccTrash
    All the ways I can think to do this seem very hackish. What is the right way to do this, or at least most common? I am retrieving a set of images from a LINQ-to-SQL query and databinding it and some other data to a repeater. I need to add a textbox to each item in the repeater that will let the user change the title of each image, very similar to Flickr. How do I access the textboxes in the repeater control and know which image that textbox belongs to? Here is what the repeater control would look like, with a submit button which would update all the image rows in Linq-to-SQL:

  • Is Git ready to be recommended to my boss?

    - by Mike Weller
    I want to recomment Git to my boss as a new source control system, since we're stuck in the 90s with VSS (ouch), but are the tools and 3rd party support good enough yet? Specifically I'm talking about GUI front-ends similar to TortoiseSVN, decent visual diff/merge support, as well as stuff like email commit notifications and general support from 3rd parties like IDEs and build systems. Even though this will be used by programmers, we really need this kind of stuff in our team. I don't want to leave everyone stuck with a new tool, and even a new source control paradigm (distributed), with nothing but a command-line app and some online tutorials. This would be a step backwards. So what do you think... is Git ready? What decent tools exist for Git and what third party development apps support it? EDIT: My original question was pretty vague so I'm updating it to specifically ask for a list of available tools and 3rd party support for Git. Maybe we can get a community wiki post with a list of stuff. I also do not consider 'use subversion' to be an adequate answer. There are other reasons to use a distributed source control system other than offline editing - private and cheap branches being one of them.

  • Placing Select Folders Under Version Control

    - by Jonah
    Hi, I have an SVN repository on my hosted server (linux), and I need to do local work on them on my windows machine (tortoise svn installed). To simplify my question, the dir structure looks like: root |--------sub1 |--------sub2 |--------sub3 ... |--------subN with additional subfolders under each subX. Say I only want certain sub-subfolders of "sub1" and "sub3" under version control. But on windows, when I commit a change with tortoisesvn, I still want to be able to right click the root folder, hit commit, and have any changes that exist anywhere under root in any selected folders to be committed. The problem is, I think using ignore would be very cumbersome, since there would be so many folders to ignore, at different levels of structure. So basically, I want to put the whole thing under version control, and then tell svn "ok, now ignore everything except X and Y". What is the easiest way to accomplish this? Thanks, Jonah

  • VB.Net 2008 Chrome or Firefox control

    - by AndyD273
    I'm trying to figure out a way to have multiple sessions at the same website at the same time. I've been using the SHDocVw.InternetExplorer control in Visual Studio 2008 to open a web browser and log in, but at times we need to use a separate login. I haven't found a way to do this using just internet explorer (it just uses the credentials of the first login), so I figure if I can find a similar control for another brower that allows DOM level access then I can just use that. If anyone knows of anything I can try that would be very helpful.

  • WPF - Handling events from user control in View Model

    - by Vitaly
    I’m building a WPF application using MVVM pattern (both are new technologies for me). I use user controls for simple bits of reusable functionality that doesn’t contain business logic, and MVVM pattern to build application logic. Suppose a view contains my user control that fires events, and I want to add an event handler to that event. That event handler should be in the view model of the view, because it contains business logic. The question is – view and the view model are connected only by binding; how do I connect an event handler using binding? Is it even possible (I suspect not)? If not – how should I handle events from a control in the view model? Maybe I should use commands or INotifyPropertyChanged?
