Update/refresh tab item content

[Brian]

I am trying to update the content of a tab without changing the selected tab.

I am using MVVM and my tab control is bound to a List of objects.  I use a DataTemplate to show the tab content.  The tab content later changes but the UI does not show the change until you switch to a new tab and back to the original tab. 

Hope this makes sense....thanks for any help!

Hi Brian,

Could you please try to use the IsContentPreserved property of the RadTabControl set to true and let us know if this helps you ? If it doesn't you can elaborate more on your scenario, the steps you perform, how you bind your controls, what are the telerik dll versions tahat you use, etc. Thank you for your cooperation.

Best wishes,

I simply want to update the content of a tab without changing the tab.  Here is my TabControl:

<Controls:RadTabControl SelectedItem="{Binding SelectedStatementDictionary, Mode=TwoWay}"
                                ItemsSource="{Binding StatementDictionaryList}"
                                ItemTemplate="{StaticResource RadTabHeaderTemplate}"
                                ContentTemplate="{StaticResource RadTabItemTemplate}"
                                DropDownDisplayMode="Collapsed" ScrollMode="Viewport"
                                Height="400" Width="500" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
                                Padding="10" telerik:StyleManager.Theme="Windows7" ScrollViewer.VerticalScrollBarVisibility="Auto">

You can see that my SelectedItem property is set.  When this property is changed, I would expect the tab content to get updated, but it does not.  I am forced to change the selected tab and then change it back and then my changes show up.

Hi Brian,

Unfortunately we still cannot reproduce this issue on our side and I am not sure whether we are not missing something from your scenario. This is why I attached the sample project we used to test this case. Can you please have a look at it and let me know if it illustrates your scenario correctly? Thank you in advance.

All the best,
