Hierarchical Grid - get key of selected detail row and its parent

[David Hodges]

I have a hierarchical grid with one detail table within each row of a Master Table.

I have GridbuttonColumns on the master table rows and detail table rows for selecting rows, and an event hooked to OnItemCommand.

In Code behind (C#) for the ItemCommand post back, how do I get the key of the detail row they selected, plus the key of that row's parent in the master table?

Thanks!

Hello David,

I hope you are trying to access the DataKeyValues fro the detailrow and the master row on clicking the button in the detail row of your hierarchial grid. If so, you can try out the following code:
aspx:

<telerik:RadGrid OnItemCommand="RadGrid1_ItemCommand" DataSourceID="SqlDataSource1" ID="RadGrid1" runat="server">
       <MasterTableView DataKeyNames="ProductName" Name="Master">
       <DetailTables>
        <telerik:GridTableView DataKeyNames="OrderID"  DataSourceID="SqlDataSource2" Name="Detail" runat="server" >
        <Columns>
        <telerik:GridButtonColumn Text="Select" CommandName="Select" UniqueName="ClickButton">
        </telerik:GridButtonColumn>
           ....

cs:

  protected void RadGrid2_ItemCommand(object source, GridCommandEventArgs e)
    {
       if (e.CommandName == "Select")
         {
            if (e.Item.OwnerTableView.Name == "Detail")
              {
                 GridDataItem item = (GridDataItem)e.Item;
                 string rowKeyValue = item.GetDataKeyValue("OrderID").ToString();
                 string parentRowKeyValue = item.OwnerTableView.ParentItem.GetDataKeyValue("ProductName").ToString();
              }
         }
     }

Thanks
