Adding contents to RadWindow

[Satish J]

Hi,

    Iam inheriting RadWindow. Pls let me know how to add controls to it using xaml. Also, let me know how to set the 

IconContent property of the RadConfirm dialog.

Any quick response is much appreciated.

Thanks,
Satish

Hello Satish,

I would recommend you to inherit the RadWindow control in XAML. In this way it is straight-forward to add any content to it. Please, refer to attached example.

About the Icon property - the RadConfirm control doesn't support such feature. If need to do this, you need to change the ControlTemplate of the RadConfirm control. If you are going to use your custom confirm control and custom confirm methods (like you said in one of your posts) you could just put your Icon in the control template of your custom control. If you need to change it dynamically you could add a property for this and to template-bind the image in the control template to this property.

Hope this information helps.

Hello. Got some troubles..
I'm trying to inherit from radwindow in my usercontrol(lets call it container), which contains other user control(and that is indicator)..

Got error something like "3521 Xaml parse exception..Failed to set UIElement.Loaded"
Container xaml:

Hi Le_Roy,

Thank you for the code snippets.

We tried to reproduce the issue following your code, but to no avail. In order to track down the source of the problem could you be so kind to send us a sample project which we can run here locally.

Looking forward to your reply.

Best wishes,
Konstantina

Sorry for a waiting time..
Here is my sample project.

Hello Le_Roy,

Thank you for your sample project.

Initialy, having xaml in both UserControls - Container and Window - is not a good practise. The error is because it is trying to call the Loaded handler from code-behind of the inherited class, not from the parent in which code-behind the handler is handled. If you place the Loaded event handler in the code-behind of the inherited class the exception will disappear, but this is not recommended.
Could you please share with us what is your scenario - why do you need to inherit the RadWindow like this? In that way we will be able to assist you in the best manner.

If you have further inquiries please let us know.

Best wishes,

I want to create window having option to indicate loading indicator "out of the box".
When my custom controls inside that window accessing webservices, i want to indicate it in generic manner.

[Konstantina]

Hi Le_Roy,

Since Q2 2010 we have added a new control to the package - RadBusyIndicator. I think it will fit your needs. You can put it in the ContentTemplate of the Window. You can find examples on its use here.

If you need further assistance please feel free to contact us again.

Kind regards,
Konstantina

[Le_Roy]

In my example project I used RadBusyIndicator.
Thanks anyway. I'll try to find another way to achieve my goals.
