SelectedItem is not set

[Richard Koslik]

Hello,

I have bound the SelectedItem Property of a TabControl, but when I start my application the property has always the value NULL until I first click onto a Tabsheet. IsDefaultItemSelected = True has also no effect.

Is use:
- Silverlight 5
- RadControlsVersion Q1 2012 SP1 (Runtime version v4.0.30319)
- GalaSoft MVVM

<telerik:RadTabControl IsDefaultItemSelected="True" TabStripPlacement="Left" BorderBrush="DarkGray" BorderThickness="1" TabOrientation="Vertical" Align="Right"  ScrollViewer.VerticalScrollBarVisibility="Auto"  VerticalAlignment="Top" Height="310" HorizontalAlignment="Left" Margin="5,581,0,0" Name="tcChild" Width="1639"
                                 SelectedItem="{Binding tabItemChild, Mode=TwoWay}" SelectedIndex="{Binding iTabIndexChild, Mode=TwoWay}">

What do I wrong??


best regards

Hello Richard,

I wasn't able to reproduce the issue. Can you please have a look at the attached sample and let me know if I'm missing something? Thank you in advance.

Hello,

thanks for your help. Your sample works fine, but my situation is another one.

My tabsheets are created directly in the xaml. I changed your sample to my situation maybe you are able to find the problem, in the older Silverlight Controls version my solution worked fine.

i will send you the .zip - file through a new support ticket.

best regards, Richard Koslik

Hi Richard  ,

 We replied in your support thread. The problem's origin is the mix between ViewModels and static Radtabitems which is not supported.

Hello,

thanks for your support, I changed now my project, create the tabitems manually and it works.
