Hi Aks,

Try the following code snippet.

ASPX:

<telerik:GridTemplateColumn UniqueName="Temp" HeaderText="Temp" >
                         <ItemTemplate>
                             <input id="Hidden1"  name ="Hidden1" runat="server" type="hidden" value='<%#Eval("ProductName") %>' />
                         </ItemTemplate>
                        </telerik:GridTemplateColumn>

CS:

 protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
     {
         if (e.Item is GridDataItem)
         {
             GridDataItem item = (GridDataItem)e.Item;
             HtmlInputHidden hidden = (HtmlInputHidden)item["Temp"].FindControl("Hidden1");
             string strtxt = hidden.Value;
             item.Attributes.Add("OnClick", "return Show( '" + strtxt + "'  );");


         }

    }

JS:

 <script type="text/javascript" language="javascript" >

     function Show(strtxt)
     {

      alert(strtxt);
     }
    </script>

Thanks
Princy.

Not exactly.  I want a function that will look thru the grid and find a hidden value that says "YES" or "NO"  ...I don't want to disply the value with each click on the grid.  Basically, when a user hits submit, I want the JS function to loop thru the grid and check the values of the hidden value.  Any ideas?  Thanks.
