Hello Dhamu,

Give a try with the following code snippet to hide the Exapand/Collapse image when there is no record in RadGrid inside NestedViewTemplate.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" OnPreRender="RadGrid1_PreRender1">
    <MasterTableView DataKeyNames="EmployeeID">
        <Columns>
           . . . . . .
        </Columns>
        <NestedViewSettings>
            <ParentTableRelation>
                <telerik:GridRelationFields DetailKeyField="EmployeeID" MasterKeyField="EmployeeID" />
            </ParentTableRelation>
        </NestedViewSettings>
        <NestedViewTemplate>
            <telerik:RadGrid ID="RadGrid2" runat="server">
                 . . . . . . .
            </telerik:RadGrid>
        </NestedViewTemplate>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid1_PreRender1(object sender, EventArgs e)
   {
      foreach (GridNestedViewItem item in RadGrid1.MasterTableView.GetItems(GridItemType.NestedView)) // loop through the nested items of a NestedView Template
       {
           RadGrid grid = (RadGrid)item.FindControl("RadGrid2");
           if (grid.Items.Count == 0)
           {
               GridDataItem parentitem = (GridDataItem)item.ParentItem;
               TableCell cell = parentitem ["ExpandColumn"];
               cell.Controls.Clear();
           }
       }
   }

Thanks,
Princy.
