Data virtualization done event

[Tobias]

Hi Telerik-team,
I just want to now, whether a data virtualizing done/completed event exists.
Let me explain the situation.
I've got a GridView, which itemsource is binded to an observableCollection.
The GridView has four columns (with Auto, *, Auto, Auto) to fill the GridViews total space. This works fine so far, but if I manually resize the width of one column, I receive a side effect, that all columnwidth are affected.
As a workaround I had the idea, to set the *-column to a fix pixel value (the current actualwidth). But this will only work, when all virtualization is done.
Can you help me with this?
Best regards
Tobias

Hello,

 There is no data-virtualization in RadGridView by default - only when you use our virtual collection.
Are you referring to the UI virtualization?

Hi Vlad,
thank you for your quick answer.
No, I am not using virtual collection. I have thought that it might be a virtualization issue, because there is a delay between the GridViews DataLoaded event fired and the data displayed on the screen.
Best regards,
Tobias

Hello Tobias,

 Generally the UI in both WPF and Silverlight is asynchronous and it is very hard to find what will be last event called since almost everything inside the application can invalidate UI. You can check this article for more info about Silverlight components lifecycle:

You can try LayoutUpdated event in your case however be careful since you can easily get famous "Layout cycle detected" exception.
