Hierarchical Grid and ShowInsertRow

[Martin]

Hello,

i have a GridView. Sometimes I need to display in this grid a hierarchical grid. I generate this grid with the following code:

GridViewTableDefinition d = new GridViewTableDefinition();
d.Relation = new Telerik.Windows.Data.PropertyRelation(item.Name);
this.radGridView1.ChildTableDefinitions.Add(d);

Now the Child Table will be displayed but I have the annoying "Sort Column" there and I cannot add any new data into the second grid, How can I insert the "ShowInsertRow"-Button and deactivate the Sort Column in the Hierarchical Grid?

Thank you,

Martin

Hello Martin,

 You can define your child tables in desired way using HierarchyChildTemplate. Here is an example:

Hello,

I tried that already but it does not work at all

I have the following in my XAML-Code

<telerik:RadGridView x:Name="radGridView1" AddingNewDataItem="radGridView1_AddingNewDataItem" RowEditEnded="radGridView1_RowEditEnded" AutoGenerateColumns="True" CanUserInsertRows="True" Grid.Row="4"
                     CanUserFreezeColumns="False" CanUserDeleteRows="True" ReorderColumnsMode="None"
                     ShowColumnHeaders="True" ShowGroupPanel="False" CanUserResizeColumns="True" CanUserSelect="True"
                     ShowInsertRow="True" Height="448" VerticalAlignment="Bottom">
    <telerik:RadGridView.ChildTableDefinitions>
        <telerik:GridViewTableDefinition />
    </telerik:RadGridView.ChildTableDefinitions>

    <telerik:RadGridView.HierarchyChildTemplate>
        <DataTemplate>
            <telerik:RadGridView x:Name="RadGridView1" CanUserFreezeColumns="False" AutoGenerateColumns="True" ShowGroupPanel="False" >
                <telerik:RadGridView.Columns>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>
        </DataTemplate>
    </telerik:RadGridView.HierarchyChildTemplate>
</telerik:RadGridView>

In my Code behind I left it like it was before. Now I cannot see any data in the hierarchical grid. I cannot set the DataSource to a fixed value.

What can I do?

Thanks,

Martin

Hi,

 You've missed to bind your child grid - you need to assign ItemsSource.

Hello Vlad,

I know. But how I can I bind the child grid from the code behind? The Itemssource differs from case to case.

No solution from setting the itemssource of the child grid from the code behind? I need to archieve this....
Thanks

Anyone knows how bind the child grid from the code behind yet?  For example, dgParentOrder.ItemsSource = Orders is OK but I could not specify/assign dgChildOrderDetail.ItemsSource althoght Child Grid called "dgChildOrderDetail" in xaml page.

Please advice!

Hello Dan,

You cannot find an element defined in a data template through its Name attribute. Furthermore, as there are more than one child grids, you will have different instances of them. I would recommend you to run through our online documentation for additional information.
