Hi,

Try the following client side code in order to get the number of items in grid.

JavaScript:

    
            <script type="text/javascript"> 
        
            function RowCount() 
        
            { 
        
                var grid = $find("<%=RadGrid1.ClientID %>"); 
        
                var MasterTable = grid.get_masterTableView(); 
        
                var Rows = MasterTable.get_dataItems(); 
        
                alert(Rows.length); 
        
            } 
        
            </script>

Shinu,

In my Grid, I have an option to Export to Excel (Button1 Click), If HierarchyLoadMode to Client it does execute the Client Side Script to Get Detail Table Row Count however Export to Export does not run. So in my Button1_Click event, I changed the HierarchyLoadMode to ServerOnDemand.

My question is if I just change the HierarchyLoadMode right before the export, after export will it change the default HierarchyLoadMode = ServerOnDemand of Master Table settings as well?

Please let me know if I am using the correct logic or not? Thanks again for all your valuable assistance. Appreciated.
