Specify column names for child relation grid

[Daniil]

Hello,

How is it possible to specify columns for child table?

I don't want columns for hierarchical grid to be auto generated.

I'm reading http://www.telerik.com/help/wpf/gridview-basic-hierarchies.html but it does not seam to be there

Thank You

Hi,

 You can use HierarchyChildTemplate similar to this demo to define your child tables.

All the best,

I'm sorry, but I still don't get it. Could you please make a WPF example?

Hello Daniil,

I am sending you a sample project demonstrating how to set the columns in a child grid. The things you need to do for defining them is to add a ChildTableDefinition:

<telerik:RadGridView.ChildTableDefinitions>
     <telerik:GridViewTableDefinition />
</telerik:RadGridView.ChildTableDefinitions>

And then to create the HierarchyChildTemplate:

<telerik:RadGridView.HierarchyChildTemplate>
     <DataTemplate>
       <telerik:RadGridView Name="playersGrid"
                             ItemsSource="{Binding Players}"
                             AutoGenerateColumns="False">
       <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn UniqueName="NameColumn" DataMemberBinding="{Binding Name}"/>
        <telerik:GridViewDataColumn UniqueName="NumberColumn" DataMemberBinding="{Binding Number}"/>


      </telerik:RadGridView.Columns>
       </telerik:RadGridView>
     </DataTemplate>
</telerik:RadGridView.HierarchyChildTemplate>

The corresponding demo example for RadControls for WPF could be found here.

Could you please show an example that access the grid children grids via code?

Hi,

 You can use DataLoading/AutoGeneratingColumn events to assess auto-generated child grid columns
