Disable ImageButton on Hierarchical Grid

[Amol]

Hello Friends,

I have a Hierarchical Rad grid which contains 4 level of Hierarchy.

On the 2nd, 3rd and 4th Hierarchy of grid, there is a template column which contains one imagebutton.

My requirement is to hide the imagebutton on the last row of  each hierarchical grid.

I had tried on Page_Pre-render event using

              ImageButton downButtonPosition = (ImageButton)radgrid.MasterTableView.DetailTables[0].Items[radgrid.MasterTableView.DetailTables[0].Items.Count - 1].FindControl("ibtnDown");

Now to retrieve last row of DetailTable of Radgrid and On Which event i can get it?

Thanks in Advance

Hi Amol,

You may try the following code snippet If you are having the ImageButton with the same ID specified in each inner level of the Grid.

ASPX:

     <MasterTableView CommandItemDisplay="Top" EditMode="EditForms" Name="Master" ShowGroupFooter="true" GroupLoadMode="Client" AllowAutomaticUpdates="True"  ShowFooter="True" DataSourceID="SqlDataSource1" DataKeyNames="ProductID" CellSpacing="-1"  >

          <Columns>
              .......
          </Columns>

             <DetailTables>
                      <telerik:GridTableView runat="server"  Caption="Detail"  DataSourceID="SqlDataSource1"  Name="Detail" CellSpacing="-1" >
                         <Columns>
                           <telerik:GridTemplateColumn UniqueName="TempCol" HeaderText="TempCol" >
                            <ItemTemplate>
                                <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/Images/dot.gif" />
                            </ItemTemplate>
                           </telerik:GridTemplateColumn>
                         </Columns>
                        <DetailTables>
                           <telerik:GridTableView runat="server" Name="Detail" DataSourceID="SqlDataSource1" >
                             <Columns>
                                <telerik:GridTemplateColumn UniqueName="TempCol" HeaderText="TempCol" >
                                  <ItemTemplate>
                                    <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/Images/dot.gif" />
                                  </ItemTemplate>
                           </telerik:GridTemplateColumn>
                             </Columns>
                           </telerik:GridTableView>
                          </DetailTables>
                      </telerik:GridTableView>
                </DetailTables>

            </MasterTableView>

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
       if((e.Item is GridDataItem)&&(e.Item.OwnerTableView.Name!="Master")&&(e.Item.ItemIndex==RadGrid1.MasterTableView.Items.Count-1))
        {
            GridDataItem item = (GridDataItem)e.Item;
            ImageButton imgbtn = (ImageButton)item.FindControl("ImageButton1");
            imgbtn.Visible = false;
        }

    }

Note: Set the Name property for each level.
