Hi,
I have Multiple Texblock in Expander Header. I want these TextBlocks aligned to Left, Right and Center.
How can i achieve this?
Please Help...
Thanks

The Text in Red should be left aligned, the one in blue should be center aligned and the green should be right aligned
Please copy the code in XAMLPad.Exe
The reason that you can't simply use a Grid or Dock panel with the TextBlocks in to control the alignment is because the default template of Expander left aligns the header content instead of allowing it to stretch.
There are two ways around this. You can either specify a width for the content of the Expander's header or you can define a new template for the expander.
The second option is probably the best, but it is also the harder one to implement. If you have Expression Blend then you can right click the Expander element in the Objects and Timeline tree and select Edit Control Parts -> Edit a copy... Once you have done that you will need to modify the HeaderSite's template as well (you can select Edit Template this time though instead of creating a copy). Once your in there you can pretty much just set it to Stretch for horizontal alignment and add a bit of margin to the right and your done.
If you don't have Expression Blend update the question to specify that and I will post some sample code. The main reason I haven't done that here is that the template is about 250 lines of code and I didn't want to generate alot of noise for no reason.
Given the reply that you gave I am guessing you don't have Blend. If you put the following XAML into XAML Pad you should see an example of an Expander which will enable the header content to span the full width of the Expander. You will most likely want to move the resources for the page into a seperate resource dictionary so you can reuse it throught the application.
