itemscontrol

I'm trying to create a custom control derived from ItemsControl . The ItemsControl is initialized with items, but they are not shown. the itemsControl : public class PipeControl : ItemsControl { static PipeControl() { DefaultStyleKeyProperty.OverrideMetadata(typeof(PipeControl), new FrameworkPropertyMetadata(typeof(PipeControl))); } public PipeControl() { Checkers = new ObservableCollection<Checker>(); Checkers.Add(new Checker()); Checkers.Add(new Checker()); Checkers.Add(new Checker()); Checkers.Add(new Checker()); Checkers.Add(new Checker()); } public ObservableCollection<Checker> Checkers {

I have an attached behavior to an ItemsControl that scrolls down to the bottom whenever a new item is added. Since I am working on a chat type program, I don't want it to scroll if the user has the scrollbar anywhere other than the very bottom as that would be very annoying otherwise(Some chat programs do this and it's awful). How do I accomplish this? I don't know how to access the wrapping ScrollViewer, or otherwise figure out if I need to bring it into view or not. This is the behavior class that I actually got from someone on StackOverflow. I'm still learning about behaviors myself. public

I have a TreeView with 3 levels in my WPF application. Level 1 and level 2 have their own HierarchicalDataTemplate . Level 3 has its own DataTemplate . Here is the XAML code: <Window.Resources> <HierarchicalDataTemplate x:Key="Level1Template" ItemsSource="{Binding Value}" ItemTemplate="{StaticResource Level2RedTemplate}"> <Border Background="Green"> <TextBlock Text="Level1"/> </Border> </HierarchicalDataTemplate> <HierarchicalDataTemplate x:Key="Level2RedTemplate" ItemsSource="{Binding Value}" ItemTemplate="{StaticResource Level3Template}"> <Border Background="Red"> <TextBlock Text="Level2"/>

Given ComboBox in the ItemsControl will have different items which is based on the DataContext of the item (not of the ItemsControl ). Can it be done? And how? Preferably from code behind. I have the following DataModel : class Tester { public Tester(string name, string surname) { Name = name; Surname = surname; } public string Name { get; set; } public string Surname { get; set; } public override string ToString() { return Name + " " + Surname; } } class TheT { public ObservableCollection<Tester> TesterObject; public TheT() { TesterObject = new ObservableCollection<Tester>(); } public string

I have this case <WrapPanel> <CheckBox>Really long name</CheckBox> <CheckBox>Short</CheckBox> <CheckBox>Longer again</CheckBox> <CheckBox>Foo</CheckBox> <Slider MinWidth="200" /> </WrapPanel> I want all the CheckBoxes inside the WrapPanel to be the same width. Adding the following almost accomplishes the desired effect <WrapPanel.Resources> <Style TargetType="CheckBox" BasedOn="{StaticResource {x:Type CheckBox}}"> <Setter Property="MinWidth" Value="75" /> </Style> </WrapPanel.Resources> However, I do not want to hardcode a specific width, rather let the largest CheckBox set the width (the

I have an ItemsControl, with its ItemsSource bound to a list of items. The size of each of the items is as small as they can be, what I need is for the control and the items in the control to stretch to fit all available space. I tried setting VerticalAlignment to Stretch on both the control, and its items (using a style). I also tried wrapping the ItemsControl in a DockPanel, and docking the ItemsControl to the bottom. How do I have the ItemsControl dynamically resize? Also some, but not all, of the item's visibilities are set to Collapsed (through the same style). Will that be a factor in
