Hello trunghieu,

Have look at this online demo showing hierarchy in RadGrid with NestedViewTemplate. Basically you need to use the ParentTableRelation setting and specify there the MasterKeyField and DetailKeyField properties in order to relate the two table.

Hi trunghieu,

 You can use the GetDataKeyValue method of the grid item, but you should have set the primary key as DataKeyName for the grid.

<telerik:RadGrid ID="RadGrid1" runat="server" ...>
            <MasterTableView DataKeyNames="CustomerID">

protected void grid_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.ExpandCollapseCommandName)
        {
            //CustomerID should be set as DataKeyNames for the parent in order for this code to work correctly
            var id = (e.Item as GridDataItem).GetDataKeyValue("CustomerID");
        }
    }

Hello Trunghieu,

Check whether the CommandName  is "ExpandCollapse" and also check for OwnerTableView's Name in ItemCommand event. Hope this helps you.
C#:

protected void RadGrid2_ItemCommand(object sender, GridCommandEventArgs e)

 {

       if (e.CommandName == "ExpandCollapse" && e.Item.OwnerTableView.Name == "DetailTable")

       {

       //your code

       }
  }


Thanks,
Princy
