Binding GridView in DataTemplate

[jean michel]

Hello,

I don't obtain binding my subGridView in DataTemplate.

In grid main I fill with a list and in subGrid I have that to fill with another list.

How I make to fill mine subGrid with another list?

My project is SL3

It follows below:

<Grid x:Name="LayoutRoot">
        <!-- Grid Principal-->
        <grid:RadGridView x:Name="GridViewEstruturaPessoa"
                          RowIndicatorVisibility="Collapsed"
                          ShowColumnHeaders="False"
                          ShowGroupPanel="False"
                          ShowColumnFooters="False"
                          ShowGroupFooters="False"
                          GridLinesVisibility="None"

Hi,

 You can use Loaded event of the child grid for example to fill the child grid will data or you can use MVVM similar to this blog post for example.

Hello Vlad,

In execution time as I can create a datatemplate in the event RowDetailsVisibilityChanged?

Thanks!

[Vlad]

Hi,

 Indeed you can do this. Here is an example:

private void grdPeople_RowDetailsVisibilityChanged(object sender, Telerik.Windows.Controls.GridView.GridViewRowDetailsEventArgs e)

        {

            e.Row.DetailsTemplate = (DataTemplate)this.Resources["MyTemplate"];

        }
