  • How can I control the height of a ListView in WPF, using a complex DataTemplate with DataTriggers?

    - by Rob Perkins
    I have a ListView element with a DataTemplate for each ListViewItem defined as follows. When run, the ListView's height is not collapsed onto the items in the view, which is undesirable behavior: <DataTemplate x:Key="LicenseItemTemplate"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Text="{Binding company}"></TextBlock> <Grid Grid.Row="1" Style="{StaticResource HiddenWhenNotSelectedStyle}"> <Grid.RowDefinitions> <RowDefinition /> </Grid.RowDefinitions> <Button Grid.Row="0">ClickIt</Button> </Grid> </Grid> </DataTemplate> The second row of the outer grid has a style applied which looks like this. The purpose of the style is to : <Style TargetType="{x:Type Grid}" x:Key="HiddenWhenNotSelectedStyle" > <Style.Triggers> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem} } }" Value="False"> <Setter Property="Grid.Visibility" Value="Collapsed" /> </DataTrigger> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem} } }" Value="True"> <Setter Property="Grid.Visibility" Value="Visible" /> </DataTrigger> </Style.Triggers> </Style> The ListView renders like this: The desired appearance is this, when none of the elements are selected: ...with, of course, the ListView's height adjusting to accommodate the additional content when the second grid is made visible by selection. What can I do to get the desired behavior?

  • Flex custom list selection not highlighting

    - by aip.cd.aish
    I want to create a custom list in Flex for an interface prototype. The list is supposed to have an image and 3 text fields. This is what I have done so far, the control displayed is what I want. But, when I click on one of the items, the item does not appear (visually) to be selected. I was not sure how I would implement this. Here is my code so far: <s:List width="400" height="220" dataProvider="{arrColl}" alternatingItemColors="[#EEEEEE, white]"> <s:itemRenderer> <fx:Component> <mx:Canvas height="100"> <mx:Image height="90" width="120" source="{data.imageSource}"></mx:Image> <mx:Label left="125" y="10" text="{data.title}" /> <mx:Label left="125" y="30" text="{data.type}" /> <mx:Label left="125" y="50" text="{data.description}" /> </mx:Canvas> </fx:Component> </s:itemRenderer> </s:List>

  • Show NSSegmentedControl menu when segment clicked, despite having set action

    - by Justin Williams
    I have an NSSegmentedControl on my UI with 4 buttons. The control is connected to a method that will call different methods depending on which segment is clicked: - (IBAction)performActionFromClick:(id)sender { NSInteger selectedSegment = [sender selectedSegment]; NSInteger clickedSegmentTag = [[sender cell] tagForSegment:selectedSegment]; switch (clickedSegmentTag) { case 0: [self showNewEventWindow:nil]; break; case 1: [self showNewTaskWindow:nil]; break; case 2: [self toggleTaskSplitView:nil]; break; case 3: [self showGearMenu]; break; } } Segment 4 has has a menu attached to it in the awakeFromNib method. I'd like this menu to drop down when the user clicks the segment. At this point, it only will drop if the user clicks & holds down on the menu. From my research online this is because of the connected action. I'm presently working around it by using some code to get the origin point of the segment control and popping up the context menu using NSMenu's popUpContextMenu:withEvent:forView but this is pretty hacktastic and looks bad compared to the standard behavior of having the menu drop down below the segmented control cell. Is there a way I can have the menu drop down as it should after a single click rather than doing the hacky context menu thing?

  • Customise a control in dynamics crm

    - by webturner
    I've written code that can make a phone dial a number from a function call, that's done and dusted. What I would like to achieve is adding a Dial button to each phone number field on the forms in Dynamics CRM. Eventually this could also create a new phone record fill in the basic details and show it to the user to enter notes and an outcome for the phone call, and perhaps some other workflow bits to schedule the next call. Can I put a custom control on a standard form in place of the standard control. I'm assuming it would have to be an IFrame to an asp.net page, that pulls in the record id, and the field name, looks up the number to show in a text box, and passes the number to the DialNumber function. Hey presto... I assume its not going to be that easy... Has anyone tried this before, what's the process, what are the gotchas?

  • Adorners for C# Windows Forms

    - by j-t-s
    Hello, I have a canvas (Panel Control) in my WinForms app where users can drag things like textbox's, labels etc around. But I want to make it easier for them to more precisely align the objects. I've read into it and Adorners seem to be the way to go? But, apparently it's only for WPF. WPF is not an option for me, unfortunately. What I'm trying to accomplish is to have lines pop up every time the user drags an object around in the canvas... Just how they work in the Windows Forms Designer View. I'd appreciate any help at all. Thank you.

  • Problem in databinding a dictionary in ListView combo-box column.

    - by Ashish Ashu
    I have a listview of which itemsource is set to my custom collection, let's say MyCollection. The code below is not full code , it's just a code snippets to explain the problem. class Item : INotifyPropertyChanged { Options _options; public Options OptionProp { get { return _options; } set { _options = value; OnPropertyChanged ("OptionProp");} } string _Name; public string NameProp { get { return _Name; } set { _Name = value; OnPropertyChanged ("NameProp");} } } class Options : Dictionary<string,string> { public Options() { this.Clear(); this.Add("One" , "1" ); this.Add("Two" , "2" ); this.Add("Three" , "3" ); } } MyCollection in my viewModel class viewModel { ObservableCollection<Item> **MyCollection**; KeyValuePair<sting,string> **SelectedOption**; } The listview Item Source is set to my MyCollection. <ListView ItemSource = MyCollectoin> I Listview contains two columns of which I have defined a datatemplats in the listview. First column is a combo-box of which Itemsource is set to Options ( defined above ) Second column is a simple textblock to display Name. Problem 1. I have defined a datatemplate for first column in which I have a combo box , I have set the Itemsource =**MyCollection** and SelectedItem = SelectedOption of the combo-box. User can perform following operations in the listview: Add ( Add the row in the listview ) Move Up ( Move row up in the listview ) Move Down ( Move down the item in the listview ) .Now when I add the row in the listview , the combo-box selected index is always comes to -1 (first column). However the combo box contains options One, Two and Three. Also, I have initialized the SelectedOption to contain the first item, i:e One. problem 2. . Let suppose, I have added a single row in a listview and I have selected Option "one" in the combo box manually. Now when I perform Move Up or Move Down operations the selected index of a combo box is again set to -1. In the Move Up or Move Down operation , I am calling MoveUp and MoveDown methods of the Observable collection. Probelm 3 How to serialize the entire collection in XML. Since I can't serialize the Dictionary and KeyValue Pair. I have to restore the state of the listview.

  • c# - clear surface when resizing

    - by dhh
    Hello, I'm trying to build my own custom control for a windows forms application in C#.Net. Currently I paint some rectangles and other graphic elements using the paint event. When I now resize the app form to fit the desktop size, all elements are repainted (which is exactly the behaviour I need) but the old one's are shown in the background. Here's what I'm doing by now: Pen penDefaultBorder = new Pen(Color.Wheat, 1); int margin = 5; private void CustomControl_Paint(object sender, PaintEventArgs e) { CustomControl calendar = (CustomControl)sender; Graphics graphics = e.Graphics; graphics.Clear(Color.WhiteSmoke); graphics.DrawRectangle(penDefaultBorder, margin, margin, calendar.Width - margin * 2, calendar.Height - margin * 2); //... } Neither the graphics.Clear, nor adding a graphics.FillRectangle(...) will hide the old rectangle from the surface. Ideas? Thank you all.

  • C# custom control to get internal text as string

    - by Ed Woodcock
    ok, I'm working on a custom control that can contain some javascript, and read this out of the page into a string field. This is a workaround for dynamic javascript inside an updatepanel. At the moment, I've got it working, but if I try to put a server tag inside the block: <custom:control ID="Custom" runat="server"> <%= ControlName.ClientID %> </custom:control> The compiler does not like it. I know these are generated at runtime, and so might not be compatible with what I'm doing, but does anyone have any idea how I can get that working? EDIT Error message is: Code blocks are not supported in this context EDIT 2 The control: [DataBindingHandler("System.Web.UI.Design.TextDataBindingHandler, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"), ControlValueProperty("Text"), DefaultProperty("Text"), ParseChildren(true, "Text"), AspNetHostingPermission(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal), AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)] public class CustomControl : Control, ITextControl { [DefaultValue(""), Bindable(true), Localizable(true)] public string Text { get { return (string)(ViewState["Text"] ?? string.Empty); } set { ViewState["Text"] = value; } } }

  • How to listen for AffectsParentArrange events when you're not the parent

    - by Jeff B
    There is an attribute "AffectsParentArrange" that implicitly invalidates the parent's layout - but I want to attach an event handler to the "event" triggered by that attribute. When a child property with the attribute changes, the parent's arrangement is invalidated. I have a custom control (which is not the immediate parent) that needs to receive an event. Does anyone know of an event that can be used here? Do I need to provide a custom parent that overrides a method and fires an event?

  • Diffrernce between BackgroundWorker.ReportProgress() and Control.Invoke()

    - by ohadsc
    What is the difference between options 1 and 2 in the following? private void BGW_DoWork(object sender, DoWorkEventArgs e) { for (int i=1; i<=100; i++) { string txt = i.ToString(); if (Test_Check.Checked) //OPTION 1 Test_BackgroundWorker.ReportProgress(i, txt); else //OPTION 2 this.Invoke((Action<int, string>)UpdateGUI, new object[] {i, txt}); } } private void BGW_ProgressChanged(object sender, ProgressChangedEventArgs e) { UpdateGUI(e.ProgressPercentage, (string)e.UserState); } private void UpdateGUI(int percent, string txt) { Test_ProgressBar.Value = percent; Test_RichTextBox.AppendText(txt + Environment.NewLine); } Looking at reflector, the Control.Invoke() appears to use: this.FindMarshalingControl().MarshaledInvoke(this, method, args, 1); whereas BackgroundWorker.Invoke() appears to use: this.asyncOperation.Post(this.progressReporter, args); (I'm just guessing these are the relevant function calls.) If I understand correctly, BGW Posts to the WinForms window its progress report request, whereas Control.Invoke uses a CLR mechanism to invoke on the right thread. Am I close? And if so, what are the repercussions of using either ? Thanks

  • JQuery validation not working for checkbox group

    - by Chris Halcrow
    I'm having trouble getting JQuery validation to work with a set of checkboxes. I'm generating the checkboxes using an ASP.NET checkboxlist, and I've used JQuery to set the 'name' attribute to the same thing for each checkbox in the list. Here's the code that gets written to the browser. I'm setting the 'validate' attribute on the 1st checkbox to set the rule that at least one checkbox must be selected. The JQuery validation works for all other elements on the form, but not for the checkbox list. I'm also using a JQuery form wizard on the page which triggers validation for each 'page' of the form, so I don't have control over how the validation is called. <input id="ContentPlaceHolder1_MainContent_AreaOfInterest_0" class="ui-wizard-content ui-helper-reset ui-state-default" type="checkbox" value="Famine" name="hello[]" validate="required:true, minlength:1"> <label for="ContentPlaceHolder1_MainContent_AreaOfInterest_0">Famine</label> <br> <input id="ContentPlaceHolder1_MainContent_AreaOfInterest_1" class="ui-wizard-content ui-helper-reset ui-state-default" type="checkbox" value="Events Volunteer" name="hello[]"> <label for="ContentPlaceHolder1_MainContent_AreaOfInterest_1">Events Volunteer</label> Any ideas on what's going wrong? There are lots of examples of JQuery scripts that will do the validation, however I'm trying to avoid this as I'm generating the checkboxlist server side by a custom control so that it can be re-used across different pages that may or may not have JQuery enabled. I'm trying to enable the JQuery validation whilst being as unobtrusive as possible, so that pages will still work even if JQuery is disabled. Here are the relevant JQuery inclusions and JQuery initialisation script for the form wizard. I'm not using any initialisation code for JQuery validation: <script type="text/javascript" src="../js/formwizard/js/bbq.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.form.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.form.wizard.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.validate.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#form1").formwizard({ validationEnabled: true, focusFirstInput: true }); }); </script>

  • ASP.Net: User control with content area, it's clearly possible but I need some details.

    - by bert
    I have seen two suggestions for my original question about whether it is possible to define a content area inside a user control and there are some helpful suggestions i.e. http://stackoverflow.com/questions/1971498/passing-in-content-to-asp-net-user-control and http://stackoverflow.com/questions/1912283/asp-net-user-control-inner-content Now, I like the theory of the latter better than the former just for aesthetic reasons. It seems to make more sense to me but the example given uses two variables content and templateContent that the answerer has not defined in their example code. Without these details I have found that the example does not work. I guess they are properties of the control? Or some such? The former example seems workable but I'd prefer to go with the latter if someone could fill in the blanks for me. Thanks.

  • RectangleGeometry with relative dimensions... how?

    - by Padu Merloti
    I'm trying to replicate the nowadays so fashionable "reflex" effect on a controltemplate for buttons I'm creating. The basic idea is to create a rectangle with a gradient fill from white to transparent and then clip some of that semi-transparent rectangle with a rectanglegeometry. The problem is that I don't know how to define a relative rectangle geometry. I kind of worked around width by defining a large value (1000), but height is a problem. For example, it works good for buttons that have a 200 height, but doesn't do anything for smaller buttons. Any ideas? <Rectangle RadiusX="5" RadiusY="5" StrokeThickness="1" Stroke="Transparent"> <Rectangle.Fill> <LinearGradientBrush StartPoint="0,0" EndPoint="0,0.55"> <GradientStop Color="#66ffffff" Offset="0.0" /> <GradientStop Color="Transparent" Offset="1.0" /> </LinearGradientBrush> </Rectangle.Fill> <Rectangle.Clip> <RectangleGeometry Rect="0,0,1000,60" /> </Rectangle.Clip> </Rectangle>

  • How to give a custom ASP.NET control the ability to parse XML markup to a collection?

    - by Vilx-
    I'm writing a custom ASP.NET webcontrol and would like it to have a collection of custom items which can also be specified in the XML markup. Something like this: class MyControl: WebControl { public IList<MyItemType> MyItems { get; private set; } } And in the markup: <asd:MyControl runat="server" id="mc1"> <MyItems> <MyDerivedCustomItem asd="dsa"/> <MyOtherDerivedCustomItem asd="dsa"/> </MyItems> </asd:MyControl> How do I do this? I though this was all about implementing some interface on the collection or adding some special attributes to the property, but nothing I do seems to work.
