Hello,

 You can set the Aggregate property of GridBoundColumn to "Custom" and in  OnCustomAggregate event calculate the aggregate set the result. Check out the following code snippet which illustrates same.

ASPX:
  
  <telerik:GridBoundColumn DataField="LastName" HeaderText="LastName" UniqueName="LastName" Aggregate="Custom" /> 

C#:
 
 protected void RadGrid1_CustomAggregate(object sender, GridCustomAggregateEventArgs e) 
    { 
       if (((Telerik.Web.UI.GridBoundColumn)e.Column).UniqueName == "LastName"
        { 
            foreach (GridDataItem item in RadGrid1.MasterTableView.Items) 
            { 
                if (item["LastName"].Text != "&nbsp;")    
                    count++; 
            } 
            e.Result = count; 
        } 
    } 

Thanks,
Princy.
