Hello Vineet Dhingra,

In your Button Click event handler (btnEdit_Click) you can cast sender argument to Button and get your data item using DataContext property. Since you have the entire data object you can access any object property.

All the best,

Vlad,

Have the exact same need as Vineet -- to find the key for the row selected. Was not able to see the DataContext object in my code (Silverlight 3.0, RadGrid/RadGridView). The grid items appear bound okay by supplying the ItemsSource in code behind. Is the choice of using ItemsSource to bind WCF results the cause of not finding the individual data elements from a DataContext?

Tried the cast you suggested, but the values from the original source were not available.

Do not see how to access the individual grid elements. _ItemDataBound event not available for this kind of binding either.

What's the technique to access the grid elements?

Thanks.

Hello Keefe Goldfisher,

You do not need such event (ItemDataBound) since you can access all data items using RadGridView Items property.

An example of the use of this would be very helpful, or a link to an example or something.
Just telling someone to use RadGridView Items property seems a bit of a copout. 
No offense intended. :)

Vlad,

Thanks for replying. We found a method to get the cell value:

<

 

telerik:RadGridView.Columns>

 

 

 

 

    <telerik:GridViewColumn Header="" Width="90" IsResizable="False" >

 

 

 

        <telerik:GridViewColumn.CellTemplate >

 

 

 

            <DataTemplate>

 

 

 

                <Button x:Name="btnEdit" Width="80" Content="Edit" Tag="{Binding ItemNo_PK}" Height="20" Click="btnEdit_Click" />

 

 

 

            </DataTemplate>

 

 

 

        </telerik:GridViewColumn.CellTemplate>

 

 

 

 

</telerik:GridViewColumn>

The use of the binding item field in the Tag attribute above did the trick. If this is a deprecated method, please let me know... and show me another way.

I don't remember seeing samples that used this technique, but I'm still getting used to Silverlight controls, so it may be lack of experience and exposure on my part.
