I want all my RadTabItem views to be built immediately. Currently, the visual tree is built when the tab is selected:

<telerik:RadTabControl
                       IsContentPreserved="True"
                       IsSynchronizedWithCurrentItem="True"
                       SelectedIndex="{Binding CurrentTabIndex}"
                       DropDownDisplayMode="Visible" IsTabStop="True">
  <telerik:RadTabItem Header="A" IsSelected="True">
    <views:MyView1 />
  </telerik:RadTabItem>
  <telerik:RadTabItem Header="B">
    <views:MyView2 />
  </telerik:RadTabItem>
  <telerik:RadTabItem Header="C">
    <views:MyView3 />
  </telerik:RadTabItem>
</telerik:RadTabControl>

I want all tabs, "A", "B" and "C", to be created immediately. (This is essential for one very complex problem that I'm trying to solve here.)

Hi Kristoffer,

Our TabControl is design to postpone visual elements creation. You could preserve already created items but you could not force their explicit creation.
The only way to do it is to select each and every tab before proceeding with the rest of your application.

Hope this helps. Please let us know if you need more info or the provided approach does not work for you.

All the best,

Ok. Would looping through the tabs and sequentially select them do the trick? E.g. in the main view's constructor? Or in the Loaded event?

Hi Kristoffer,

I would suggest using a dispatcher in the Loaded event. This should validate that the tab control is initialized.

Hope this helps. Please let us know if you need more info.
