GridViewRowDetailsEventArgs not fired

[loic]

Hello,

I am trying to populate a child RadGridView in a parent RadGridView, only when a parent row is expended (Because of too much data)
I tried to use the RowDetailsVisibilityChanged event, but It never fired. So tried the LoadingRowDetails event with the same ressult.
This two events work with GridViewRowDetailsEventArgs, So, I guess I have something wrong in my code which generates a compatibility issue, but I really don't know what and why.

This is my Xaml code

 

 

<telerikGrid:RadGridView x:Name="dgMetaRess" VerticalAlignment="Stretch" AutoGenerateColumns="False" UseAlternateRowStyle="True"

 

 

Margin="10,10,10,0" Visibility="Visible" CanUserSortColumns="True" ShowGroupPanel="False"

 

 

 

Style="{StaticResource RadGridViewStyle}" RowDetailsVisibilityChanged="dgMetaRess_RowDetailsVisibilityChanged"

 

 

RowDetailsVisibilityMode="Collapsed" LoadingRowDetails="dgMetaRess_LoadingRowDetails"

 

 

 

IsReadOnly="True" DataLoaded="MakeDataGridViewTransparent_DataLoaded">

 

 

 

    <telerikGrid:RadGridView.ChildTableDefinitions>

 

 

 

         <telerikGrid:GridViewTableDefinition />

Hi loic,

You are confusing the Hierarchy feature with the Row Details feature. They are completely different.

Does that mean there is no way to access methods on the nested tables with the Hierarchical GridView?  Only with RowDetails (LoadingRowDetails, RowLoaded, RowUnloaded, etc)?

Hello,

You can always subscribe for RowLoaded and RowUnloaded events of RadGridView. If you use hierarchy (and not RowDetails), then you can subscribe for the 
RowIsExpandedChanged/RowIsExpandedChanging events to get notified when the user expands the hierarchy items.
