Instead of attaching a PreviewKeyUp event with each TextBox in my app and checking if the pressed key was an Enter key and then do an action, I decided to implement extended version of a TextBox that includes a DefaultAction event that fires when an Enter Key is pressed in a TextBox. What I did was basically create a new Class that ex...
I'm trying to get the SL Tookit (March 2009) Accordion control to populate the ItemTemplate of a TreeView control, but it doesn't render properly (just a 1x1 pixel square). Here's my XAML: <UserControl x:Class="SilverlightTest.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas....
Beware, this is a rather basic question (I think). I have a UserControl, called MyUserControl. I use it in a DataTemplate for my ListBox: <l:MyUserControl DataContext="Test" /> Now I want to access this DataContext in the code-behind of MyUserControl, and I expect DataContext to contain a string object with contents "Test". However, ...
In my XAML I get all customers by binding to a GetAll property: <ListBox ItemsSource="{Binding GetAll}" ItemTemplate="{StaticResource allCustomersDataTemplate}" Style="{StaticResource allCustomersListBox}"> </ListBox> The GetAll property is an observable collection in my view model, which calls the Model to get all collecti...

How can I make the top and bottom padding smaller in the following label? As I see it, the bounding box in much bigger than it needs to be, but the padding is set to 0, so it cannot be any smaller. <Label Background="AliceBlue" Content="1800" FontSize="170" FontWeight="Bold" Foreground="Gray" Padding="0" /> ...
Every time I write out a setter whose Value property value isn't describable inline, I curse the fact that the API doesn't mark the Setter class with [ContentProperty("Value")], which would allow this: <Setter Property="BitmapEffect"> <Setter.Value> <OuterGlowBitmapEffect GlowColor="#AAC" Opacity="0.2" GlowSize="1.25" /> </Sette...
I want to have a TextBox which Height grows as Iam entering lines of Text. I've set the Height property to "Auto", and so far the growing works.

I've got the following XAML used to display detailed information about an item selected in a list view. I want the rectangle to show the standard info color behind the text except when the selected item represents an error message. The code below doesn't work as is and always shows the info color. It works great if I don't specify a Fill...
Hy, I have a validator set on the text property of a textblock. For a correct validation I would need the parent usercontrol of the textblock, but the only things I have in the validator are the value object (a string) and the culture (doesn't help either). Does anyone know a way to get certain usercontrols in a class/a method where I ...
I have WPF application with one main window. In this window there are a series of buttons which form a menu and a space where user controls are loaded at runtime. However, if the user changes data (stored in XML file) in one user control and then switches to another user control, the user does not see the updated data in the new user c...
I found this code which replaces the default select style with a custom style for the select ListBoxItem in a ListBox. However, there is still a little blue line on the left from the default style which I can't remove with any padding or margin changes. How can I remove that blue line and completely determine the style of the selected L...

I am trying to get the effect of "dimming out the whole window and all controls on it". The window and everything on it also needs to be disabled. The problem is that when button is disabled, it doesn't seem to let you change the Background color. Is there a way in WPF to change the background color of a button even though it is disa...
I have a bool value that I need to display as "Yes" or "No" in a TextBlock. I am trying to do this with a StringFormat, but my StringFormat is ignored and the TextBlock displays "True" or "False". <TextBlock Text="{Binding Path=MyBoolValue, StringFormat='{}{0:Yes;;No}'}" /> Is there something wrong with my syntax, or is this type of ...

I'm new to .NET programming, and trying to learn Silverlight 2 / C#. I need to declare numeric constants (or better yet, readonly variables), and access them in both XAML and my C# code-behind file. These values are more appropriately defined in XAML, but if the definition needs to be done in C#, that's better than hard-coding the val...
