[Solved] HierarchyChildTemplate

[Moshe]

Hi,
Can you give me example of using HierarchyChildTemplate(with 2 radGridView) programmatically?
For each radGridview I'm using wcf service.

Thanks in advance,
Moshe

Hi,

 You can use HierarchyChildTemplate to load completely separate user control for place holder where you can create programmatically desired grid(s).

Hi Vlad,
I'm using this snippet:

<telerik:RadGridView Grid.Column="0" Grid.Row="0" x:Name="radGridBidRows" AutoGenerateColumns="False"
                  SelectionUnit="FullRow" CanUserSelect="True" SelectionMode="Single"    
                  SelectionChanged="radGridBidRows_SelectionChanged" SelectionChanging="radGridBidRows_SelectionChanging" DataLoaded="radGridBidRows_DataLoaded" DataLoading="radGridBidRows_DataLoading" RowLoaded="radGridBidRows_RowLoaded">

            <telerik:RadGridView.ChildTableDefinitions>
                <telerik:GridViewTableDefinition />
            </telerik:RadGridView.ChildTableDefinitions>
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding BID_ROW_ID}" Header="BID_ROW_ID"  />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding BID_ID}" Header="BID_ID"  />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding POL}" Header="POL"  />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding POD}" Header="POD"  />

            </telerik:RadGridView.Columns>

            <telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>

                    <telerik:RadGridView x:Name="radGridPriceColumnsRows"                                             
                     SelectionUnit="FullRow" CanUserSelect="True" SelectionMode="Single"    
                     AutoGenerateColumns="False" Width="1200" BeginningEdit="radGridPriceColumnsRows_BeginningEdit" RowEditEnded="radGridPriceColumnsRows_RowEditEnded" >
                        <telerik:RadGridView.Columns>

                            <telerik:GridViewDataColumn DataMemberBinding="{Binding PRICE_COLUMN_ID}" Header="PRICE_COLUMN_ID"  />
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding BID_ROW_ID}" Header="BID_ROW_ID"  />
                            <!--<telerik:GridViewDataColumn DataMemberBinding="{Binding CONTAINER_TYPE_ID}" Header="CONTAINER_TYPE_ID"  />-->

                            <telerik:GridViewDataColumn IsReadOnly="True" DataMemberBinding="{Binding EQUIPMENT_TYPE_NAME}" Header="EQUIPMENT_TYPE_NAME"  />
                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>

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

        </telerik:RadGridView>

Master an details are connected with BID_ROW_ID.
What event I must use to fil details by current BID_ROW_ID?
Can you give me example of using HierarchyChildTemplate in run time?

Thanks,Moshe

Hi,

As I said in my previous reply you can declare in this template a user control and create dynamically desired grid(s) in this control. The DataContext of the control is your parent data item - if you cast it to your type you can access desired properties directly.

Hi,

I still didn't understand how can I connect parent and child grids even if I implement all in separate user control.
What's event serves for this purpose?
May be you can give snippet or project that implements programmatically HierarchyChildTemplate?

Thanks,Moshe
