Hi nagendra,

You can do this in the ItemCommand event in the following way:
 
protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName=="MyCommandName")
        {
            e.Item.Expanded = true;
            GridTableView gridNestedView = (e.Item as GridDataItem).ChildItem.NestedTableViews[0];
            gridNestedView.IsItemInserted = true;
            gridNestedView.Rebind();
        }
    }
in the markup for the master grid you need to make a button column with the specified CommandName that will trigger this operation:
<MasterTableView ...>
      <Columns>
           //...
             <telerik:GridButtonColumn UniqueName="btnCol" ButtonType="PushButton" CommandName="MyCommandName" Text="MyCommand"></telerik:GridButtonColumn>
      </Columns>
</MasterTableView>

Let me know how this works for you and if you have any other questions.
