RadRichTextBox crashs with ArgumentNullException

[Thomas]

I try to use a RadRichTextBox in a grid. Everytime, if i select the element in Code, i get an ArgumentNullException.

Any Ideas?

Regards Thomas

<Grid x:Name="LayoutRoot" Background="White">

       <Grid.RowDefinitions>
           <RowDefinition/>
           <RowDefinition Height="Auto"/>

       <telerik:RadGridView  x:Name="AdressenGrid"
                             ItemsSource ="{Binding Screen.Q_AdresseNachMatchCode, Mode=TwoWay}"
                             SelectedItem="{Binding Screen.Q_AdresseNachMatchCode.SelectedItem, Mode=TwoWay}"

Hello Thomas,

Unfortunately, we were not able to reproduce the problems described. Could you please verify that all needed references have been added to your project?

We are not sure that we understand exactly what you mean with "select the element in Code", so we would appreciate if you could send us sample codes for this. It would be great if you could isolate the problem in a sample project and send it back to us using a support ticket.

Regarding the wizard issue, could you please share addition information like inner exception and stack trace? Does the exception occur only when creating a new user control оr each time? Exact steps to reproduce will be very helpful.

Looking forward to your reply.

Kind regards,
Vasil
the Telerik team
