I have a rad grid and textbox that is in an UpdatePanel.  The grid has paging, dynamic tooltips on mouse over, and it's datasource is a sql stored procedure

I have a text box that is not within the grid that I want to use to filter.  I'm able to get the AJAX manager called when text is entered into the field.  However, I'm having issues with the filtering.

I can't see what I'm missing...

Hi,

Try Rebinding the Grid instead of  DataBind() and see whether it is working.

CS:
protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e) 
       { 
           if (e.Argument.IndexOf("StaffGrid") != -1) { 
               if (this.TextBox1.Text == "") { 
                  StaffGrid.MasterTableView.FilterExpression = ""
              } 
               else { 
                   StaffGrid.MasterTableView.FilterExpression = this.TextBox1.Text; 
               } 
               StaffGrid.Rebind(); 
           } 
          
       } 
   } 


Thanks
Shinu.

I tried Rebind, however the grid doesn't filter or rebind.  It goes to the StaffGrid_Itemdatabound.
