Hi, I am just using the radgrid to show the data from a dynamic datasource, everything is ok except when I enable the aggregrate function for the autogenerated columns it gives me the error "Column 'xxxx' not belong to the table", below is my C#code:

    
            using System;  
        
            using System.Data;  
        
            using System.Configuration;  
        
            using System.Collections;  
        
            using System.Web;  
        
            using System.Web.Security;  
        
            using System.Web.UI;  
        
            using System.Web.UI.WebControls;  
        
            using System.Web.UI.WebControls.WebParts;  
        
            using System.Web.UI.HtmlControls;  
        
            using Telerik.Web.UI;  
        
            using System.Data.SqlClient;  
        
            public partial class test : System.Web.UI.Page  
        
            {  
        
                protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                }  
        
                protected void RadGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)  
        
                {  
        
                    this.RadGrid.DataSource =  GetReportDataset() ;  
        
                }  
        
                private DataSet GetReportDataset()  
        
                {  
        
                    SqlConnection sqlconn = new SqlConnection();  
        
                    sqlconn.ConnectionString = ConfigurationManager.ConnectionStrings["NorthWind"].ConnectionString;  
        
                    SqlCommand sqlcomm = new SqlCommand("select CategoryID,ProductName,UnitPrice,UnitsInStock,UnitsInStock  From Northwind.dbo.Products", sqlconn);  
        
                    sqlcomm.CommandType = CommandType.Text;  
        
                    DataSet ds = new DataSet();  
        
                    SqlDataAdapter adapter = new SqlDataAdapter();  
        
                    adapter.SelectCommand = sqlcomm;  
        
                    sqlconn.Open();  
        
                    adapter.Fill(ds);  
        
                    sqlconn.Close();  
        
                    return ds;  
        
                }  
        
                protected void show_Click(object sender, EventArgs e)  
        
                {  
        
                    this.RadGrid.Rebind();  
        
                    this.RadGrid.Visible = true;  
        
                }  
        
                protected void RadGrid_ColumnCreated(object sender, GridColumnCreatedEventArgs e)  
        
                {  
        
                    if (e.Column is GridBoundColumn)  
        
                    {  
        
                        GridBoundColumn col = (GridBoundColumn)e.Column;  
        
                        if (col.DataField != "Group" && col.DataField != "Store")  
        
                        {  
        
                            col.Aggregate = GridAggregateFunction.Sum;  
        
                        }  
        
                    }  
        
                }    
        
            }

            </body> 
        
            </html>

when I enable the aggregate by using:
col.Aggregate = GridAggregateFunction.Sum;

it gives me error
"Column 'ProductName' does not belong to table"
in the RadGrid.Rebind();

anyone know why this happens?
Thx
