Hi,
I'm trying to pass the window object of a window type RadWindow as command parameter to the code behind - however not RadWindow will be passed, but some helper windows classes of type WindowHostWindow.
The XML look like this:
<telerik:RadRibbonButton Text="Speichern"
AllowDrop="True"
LargeImage="..\Images\save.png"
Size="Large"
telerik:ScreenTip.Title="Speichern"
telerik:ScreenTip.Description="Einen neuen Task anlegen."
telerik:KeyTipService.AccessText="S"
IsEnabled="{Binding CanSave}"
Command="{Binding SaveCommand}"
CommandParameter="{x:Reference Name=taskwindow}"
IsDefault="True"/>
The Code behind(implementation of the command):
private void SaveProcess(object obj)
{
...
RadWindow wnd = (RadWindow)obj; <= this cast already fails as some helper class will be passed instaed of the expected RadWindow
Using the "normal" Window class instaed of the Telerik one, the code runs without any issues.
Looking forward to your answer.
Thanks,
Joachim

Thank you for your interest in our RadWindow control.
I have tested your scenario but wasn't able to reproduce it on my side. I am not familiar with your implementation set-up but I am assuming that you have placed RadRibbonView control inside RadWindow as a MainWindow. Attached to this reply is the sample project which I used to test your scenario based on the provided code snippet. In the command executed method of the SaveCommand, the parameter is the RadWindow. Can you take a look at this project and let me know what I am missing in order to reproduce this behavior my side.
Looking forward to your reply.

Hello Dinko,
thank for your reply. Unfortunatelly your assumption is not fully true. The windows is used as a kind of popup for creating a new data entry (like new email).
Following shows the structure of the window. The command is part of the data context in the back:

Hope this full sample gives you the necessary hints for reproducing the issue.
Thanks,

Thank you for the provided code snippet.
I manage to reproduce this helper class which comes as a parameter. Basically, CommandParameter is bind to a parent of type Window using RelativeSource. To get the RadWindow you can set the AncestorType to be {x:Type telerik:RadWindow}. I have modified my project to demonstrate this approach. Give it a try and let me know if it works on your side.
