Hi,
I'm trying to make one custom controller that extends the RadWindow. This controller will have 2 different zones: 1 is the content and the second one footer.
So, to do this, i tried to change the dataTemplate of the content.
The code above is the just with the content with one button (marking the area of the footer).
Then in mainpage i call this dialog and add one button to the content:
The strange thing (at least for me!!) is when in the code-behind of the mainWindow (c#) if i try to call the "
buttontoDisable" (say for example disable it), gives to me a "System.NullReferenceException".
What i'm doing wrong here?
