I am having a problem displaying an image with a web URL in a WPF user control. I have worked through all the suggestions for a similar problem asked on this site in Aug 2008 (http://stackoverflow.com/questions/20586/wpf-image-urisource-and-data-binding) but none of those suggestions have worked. What I'd like to do is: <Image Width="...
Hi, First off I'm new to XAML so forgive me if I've done something stupid.

When I attempt to specify multiple DataTemplates for use by a ContentControl so that the correct one (based on Type) is used, I end up with Content that is simply the Content's ToString() value. <ContentControl DataContext="{Binding MyTreeRootViewModels}" Content="{Binding /, Path=CurrentlySelectedTreeViewModel}"> <ContentControl.Reso...
Is there any property or state I can set on a expander object that makes it unexpandable but still can be selected? I'm thinking for example of the last Child in a TreeView where I don't wan't the Expander to have an expander button. But other uses could be if someone doesn't have access to more then the header or something along that l...
Hey everyone, I have a TextBlock and a Textbox in the same location. Depending on what mode the user is in, I make one visible and the other collapsed. This is working fine, but how can I make the Textblock scrollable? I figured I should use a ScrollViewer, but I don't know why it's not working. I've tried messing around with the heigh...
Hi, I have a StackPanel that I dynamically change the contents of every 5 minutes to show the user messages. These messages are displayed as TextBlock or HyperLinkButton. I'm wondering how/if I can set a style within the StackPanels style that will apply to the children. E.g. I've tried <Style x:Key="InfoBarStyle" TargetType="StackP...
Hi Folks I'm trying to get a button to display an icon in XAML. Initially I wanted to paste a character instead, but vb Express 2008 would not recognise it being a symbol as it is not a regular character. Then I created an icon and tried to set the button image property to reference it, but this does not exist, so more misery. Now I've ...

Hello again. I'm working on a WPF project, and my intention is to make two specific RadioButtons alter properties of another specified Component. But for now, i'm just trying to store a String inside the RadioButton. For that, I've created a behavior class: public class AdjustBehavior : Behavior<RadioButton> { With this property...
I'm hoping this will be my last question today. I'm in a hurry and google is not helping much (that or I'm searching the wrong places). I created some custom properties and behaviors so my RadioButtons can alter my labels Content and the mask of my TextBoxes. I could pass a String as a property, but how do I pass another control as a p...

I have a data class in my application which maintains a collection of byte arrays representing JPEG images. It's defined as: private ArrayList FrameList = new ArrayList(); I'm having some troubles with my Image object rendering a blank page (and taking its sweet time to do it as well). When I insert a blank image with a 2K in-memory b...
