  Hi,
  
  my requirement is to show list of values in a grid and when the user clicks on one of the columns, I have to display a radbutton. this button is on the page and is outside the grid
  I am getting the commandname in the itemcommand event and trying to make radbutton visible.  button.visible=true. when i debug the code it looks like its working but the button is not diplayed. this button is invisible by default.
  do i have to do a find control like i do for the controls inside the grid? if so what is the syntax for it?
  
  Thanks.

  Hello,
  
  Please check below code snippet.

          <AjaxSettings>

              <telerik:AjaxSetting AjaxControlID="RadGrid1">

                  <UpdatedControls>

                      <telerik:AjaxUpdatedControl ControlID="RadGrid1" />

                      <telerik:AjaxUpdatedControl ControlID="Button1" />

                  </UpdatedControls>

              </telerik:AjaxSetting>

          </AjaxSettings>

      </telerik:RadAjaxManager>

  I have another Issue now. I think this is also related to the above thats why I am posting in the same thread.
  
  I am trying to give a download functionality to the user on my page.
  
  

  Response.ClearContent()

  Response.ContentType =

   

  "application/vnd.xls"

   

  Response.AppendHeader(

   

  "Content-Disposition", "attachment; filename=" & OnlyName)

   

  Response.TransmitFile(filename)

  Response.End()
  
  the above code does not seem to work. this is on the same page where I have my Radgrid. What could be the work around for this?
  
  Thanks

  Hello,
  
  

  <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

          <ClientEvents OnRequestStart="onRequestStart" />

           

      </telerik:RadAjaxManager>

  <script type="text/javascript">

          function onRequestStart(sender, args)

          {

              if (args.get_eventTarget().indexOf("lnkDownload") >= 0)

              {

                  args.set_enableAjax(false);

              }

          }

      </script>

  <MasterTableView DataKeyNames="ID" >

                  <Columns>

                       

                      <telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID">

                      </telerik:GridBoundColumn>

                       

                      <telerik:GridTemplateColumn>

                          <ItemTemplate>

                              <asp:LinkButton ID="lnkDownload" runat="server" Text="Download sample excel file"

                                  OnClick="lnkDownload_Click" CausesValidation="false"></asp:LinkButton>

                          </ItemTemplate>

                      </telerik:GridTemplateColumn>

                  </Columns>

              </MasterTableView>

  protected void lnkDownload_Click(object sender, EventArgs e)

          {

              // you can access your grid row

              Button lnkDownload = sender as Button;

              GridDataItem item = lnkDownload.NamingContainer as GridDataItem;

              string str1 = item.GetDataKeyValue("ID").ToString(); // by datakey ID

              string str2 = item["ID"].Text; // by column name

              try

              {

   

                  string path = Server.MapPath("~/filepath/YourFilename.xlsx");

                  string attachment = "attachment; filename=yourfilename.xlsx";

                  Response.Clear();

                  Response.AddHeader("content-disposition", attachment);

                  Response.ContentType = "text/plain";

                  Response.WriteFile(path);

                  Response.End();

              }

              catch (Exception ex)
