Hello Telerik team,

first i will thank you for your great work. For all problems i had with telerik till now, i could find the solution in Documentation, the Blogs or this Forum. But now i had a problem which i could not solve.

I use a GridView for displaying viewmodels which had self viewmodels from which i need some data. For validation i use the INotifyDataErrorInfo-Interface. Buit the GridView doesn't register itself on the ErrorsChanged-Event from the viewmodels which are not direct in the datacontext from a row.

Example:
<telerik:RadGridView  ItemsSource="{Binding List}"  AutoGenerateColumns="false">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn  DataMemberBinding="{Binding Name}"/>
        <telerik:GridViewDataColumn  DataMemberBinding="{Binding CurrentYear.Value}"/>
    </telerik:RadGridView.Columns>
</telerik:RadGridView>
If the CurrentYear-ViewModel has an error, which can occure asynchrone, the GridView doesn't notice it.

In the Version from 2010 Q3 SP1 this works correctly, but now i test with the 2011 Q1 SP1-Trial this problem occure.

Best wishes

Lothar

Hi Lothar,

This sounds very strange. I've just checked a similar scenario and it is working fine on my end. Could you please send me a sample project, which I can debug on my side in order to see what is going on?

P.S. You have to open a separate "support" ticket in order to be able to attach files. Thank you in advance.

Greetings,
