Hello varsha Motwani,

I am sending you a sample project showing a possible way of getting to the nested grid items. In this example, on clicking the button, the visibility of a column from the child grid is set to collapsed.
I hope that helps.

Kind regards,

What if you added another child gridview to the parent.
I have a senerio where I have a parent gridview with 2 child gridviews and in the second child gridview I have a combobox and when the user selects a "Title" from the drop down I want to change the rest of the cells.

So you select a title and then the author and publisher cells get updated from my object.
The title, author, publisher is an example of what I am trying to do.
Below is your xaml sample with another gridview added.
And the below c# code is my code for trying to get the selected index value so I can set my object with the new values from the selected title.

<telerik:RadGridView Grid.Row="0"

Name="clubsGrid"

ItemsSource="{Binding Clubs}"

AutoGenerateColumns="False" IsSynchronizedWithCurrentItem="True"

Margin="5">

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition />

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Established}"

Header="Est."

DataFormatString="{}{0:yyyy}"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding StadiumCapacity}"

Header="Stadium"

DataFormatString="{}{0:N0}"/>

</telerik:RadGridView.Columns>
