I have a button on a ControlTemplate. I want to handle its click events in the control that uses the template. How would I make that happen?
<ControlTemplate x:Key="UDPTemplateTabControlEx" TargetType="{x:Type TabControl}">
<Grid x:Name="Grid" KeyboardNavigation.TabNavigation="Local">
<ScrollViewer x:Name="HeaderPanelEx" Grid.Row="0" Grid.Column="0"...>
<ScrollViewer.Style>
<Style TargetType="{x:Type ScrollViewer}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Grid Margin="0,0,0,0" Grid.Row="0" x:Name="HeaderPanelEx">
<Button Grid.Column="0" Width="25" Content="..." />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ScrollViewer.Style>
</ScrollViewer>
</Grid>
</ControlTemplate>
I tried putting a name property on it, but I still can't see it in intellisense in the code...

Why is common sense not common?

It can also depend on where the template is defined.
If it's in a place backed by code-behind (ie a class) then you can add
an event handler like you would anywhere else.
If the template is in a resource dictionary or some other place without a class
then maybe implementing a command as Wes mentioned would be the way to go.
You can also wire event handlers at runtime, perhaps by overriding OnApplyTemplate()[^] and
using FindName()[^] to find the button instantiated by the template.

I'm not sure about the event stuff in WPF yet. I mean, sure, I'm handling click events from buttons and stuff, but I'm not sure about the routed event thing. I haven't found a decent explanation that also includes a decent example of it either. I'm sure that I should look at the routed event stuff, because I'm making controls public in user controls that I have to handle in the form or user control that hosts them, and it just feels wrong to do that.

For me, custom commands are the way to go, also in terms of clean separation of presentation and logic. You can use the CommandParameter property to submit some contextual information.
Edit: I guess you might derive your command from RoutedCommand if you want it to bubble up the tree, which would simplify handling the event in the control that makes use of the template.

You can also simply data bind the Button.Command to an ICommand on located on the DataContext.
This is excactly how MVVM applications work.
You can also assign the delegate for the ClickEvent or the Commmand at run-time. I've see this also.
Another way is to set up an AttachedEvent at a parent object where this button and possibly others grouped. Then just handle the Button.ClickEvent.
All are very acceptable techniques.

You mean the Silverlight ToolKIT from the Codeplex site?
If so, the one for Silverlight 2 or the one for Silverlight 3 Beta?

Hello,
I try to use Silverlight_Tools for Version 2.0 because Version 3 is marked as beta!?!?
May I have to try version 3 as well.

Version 2 should be what you want, unless you're going to use the beta.
You can't currently have 2 and 3 on the same dev environment.
Make sure you've installed Visual Studio 2008 SP1 and the Silverlight Tools
for Visual Studio 2008 SP1.
What's the error you get?

Hi,
I'm working on an small c# test-application as I'm really new to wpf/xaml coding. The App creates a WPF Window with controls and standard dynamic styles.
Runtime I would like to change the style. I don't want to remove and set another style, but get the current style of the control and change things in c# code behind.
I know how to get the style, add new Setter or trigger and remove and the style and add a new style.
What I couldn't find out, if it is possible, is how to change the property values of the given style.
Example: I have an Window with a given "Width" of 600. Now I want to change the width to 300. I could do it in c# I know, but I would like to chagne the given style. Background is, that I would like to save the style in an file and reload it later..
Some Code:
XAML
<br />
<style x:key="MyWindowStyle" targettype="Window" xmlns:x="#unknown"><br />
<setter property="Width" value="600" /><br />
<setter property="Height" value="300" /><br />
</style><br />
C#
<br />
public void SetFirstTemplate()<br />
{<br />
<br />
MyWindowStyle = ((Style)this.Resources["MyWindowStyle"]);<br />
<br />
<br />
}<br />
Has someone experience with that?

Thanks for that Article link, i missed that one.
It's real cool and will be helpful later.
I think I haven't stated out what I really want to achieve.
For now, the purpose of my app is to create something like an style designer.
For that, I need to change the style it self on runtime.
The article assumes you have a number of ready styles you want to change, load and and unload in your skinnable application. That is not what I want to do. I want to change a given simple style to create a new one. When the user is ready with it, it should be saved as an dictionary.xaml file.
What happens then, load into an skinnable app as loose or compiled version doesn't matther at this point.
Thanks again.

hi i want to show notifications to user when it is uploading.like i want to show the current status while uploading in the label.so can anyone help how to do this in wpf?

Which part are you having trouble with?
You can set a label's content any time from code as long as you do it on the UI thread.
Have you tried something that isn't working? If so, can you show an example?

Hi guys
I use the following line of code to load .chm files whenever the user presses F1 on a textbox:
TextBox h:HelpProvider.HelpString="filename.chm"
But this only works when the .chm file is in the "bin" folder, how can I specify a different path to my help files?
I want to have a seperate folder called "help"

By changing the value. If the help folder is to be deployed in a subfolder of the executable, you'd use @"Help\filename.chm"

Thanks for the speedy reply, but that doesn't when I use work though, I get the following error message "Character sequence '@' was not expected at this location."
I'm guessing your code will work in the code behind file?! But it does not work when I use it in the XAML part.
PLEASE NOTE: I'm trying to integrate context sensitive help into my application, it has to load different help files depending on what control the user pressed F1 on. I'm using this part of code in the code behind file to display the help files:
static private void Executed(object sender, ExecutedRoutedEventArgs e)
{
//MessageBox.Show("Help: " + HelpProvider.GetHelpString(sender as FrameworkElement));
System.Windows.Forms.Help.ShowHelp(null, HelpProvider.GetHelpString(sender as FrameworkElement));
}
The main thing I'm trying to do here is to NOT hard code the path to my help files.
