Animate Shape inside a ListBoxItem Control Template bound to an ObservableCollection

Posted By:      Posted Date: October 14, 2010    Points: 0   Category :WPF


I basically have a listbox with a circular panel template, bound to an observablecollection "Hosts" defined like so:

<ListBox x:Name="listbox1" ItemContainerStyle="{DynamicResource ListBoxItemStyle2}" ItemsSource="{Binding Hosts}">
  	<ControlTemplate TargetType="{x:Type ListBox}">
  		<WpfApplication7:CircularPanel AngleItem="{Binding Angle}" IsItemsHost="True"/>

<Style x:Key="ListBoxItemStyle2" TargetType="{x:Type ListBoxItem}">
	<Setter Property="Template">

Again, Getting control inside datatemplate from code behind

HI, All: This problem comes back to bite me again. I had a similar problem before but I changed the customer control to user control and define the click event in the xaml. But this time I have to stick with the customer control. I searched the internet and there are a lot of examples but in my situation, I still got null object. I have a CUSTOMER control which derives from treeview. The hierachicalDataTemplate for the treeview is following:     <HierarchicalDataTemplate         x:Key="CheckBoxItemTemplate"         ItemsSource="{Binding SubFolder}"         >         <StackPanel Orientation="Horizontal">             <CheckBox             x:Name="PART_CheckBox"             Focusable="False"             IsChecked="{Binding IsSelected}"             VerticalAlignment="Center"                 &nbs

Creating a volume control slider/setting one template property based on another

So, what I want to do, is to make a volume control that looks like a right angle triangle with the 90 degree angle on the bottom right, and then when you click on it, the area to the left of the selected point is shown in a different color.  In other words, I've created a slider with the right background, what I can't do, is work out how to show the selected area by filling in the triangle.  I have worked out how to bind the height of my triangle on the left to the value of the control, but right now, the rate of rise is exactly half of what I need it to be.  I need to know how to change the template for the area to the left of the selection ( which is the repeat button ) so that the background is twice the height that it is right now.  No matter what size I make the slider, the area is always 1/2 the size it needs to be, so I am sure if I could get it to double inside my template, it would work fine. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">       <Style x:Key="SliderButtonStyle" TargetType="{x:Type RepeatButton}">         <Setter Property="SnapsToDevicePixels" Value="true"/>         <

Get value of a label control inside the DetailsView

Hi everyone, I have a databound label control (i.e. Label 3) inside an Item Template that's in a DetailsView control. I just need to get the value of those label and compare it to some string. I tried several ways (i.e. Find control, DetailsView.Row) but nothing seems to work. I don't know if I'm using the FindControl methos correctly or if I need to access the Row first and do the findcontrol method.  Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound 'If (DetailsView4.Rows(2).Cells(1).ToString = "Regular") Then 'Label3.ForeColor = Drawing.Color.Azure 'End If 'Dim StatusQualifierContainer As Label 'Dim S As String 'StatusQualifierContainer = DetailsView4.FindControl(Label3.Text) 'S = StatusQualifierContainer.Text 'If S = "Regular" Then 'Label5.ForeColor = Drawing.Color.Aqua 'End If 'Dim C As Label = DetailsView4.FindControl("Label3") 'If C.Text = "Regular" Then 'Label3.ForeColor = Drawing.Color.DarkBlue 'End If 'Dim headerRow As DetailsViewRow = DetailsView4.HeaderRow 'Dim lblText As Label = CType(headerRow.FindControl("Label3"), Label)
