                BindDate(serverSources);
            }
        }

        private void BindDate(IQueryable source)
        {
            dt = null; 
            dt = Utilities.Utilities.ConvertToTable(source,null);
            Store1.DataSource = dt;
            Store1.DataBind();
        }

Click button Gridpanel don't show data,but "protected void btnSource_Click(object sender, DirectEventArgs e)" channge to "protected void Page_Load(object sender, EventArgs e)", the data can show to Gridpanel.

Why?

Try to call GridPanel1.Reconfigure() right after binding the data.

Also, if you do this on the event handler of a button, you do not need the if condition... [ if (X.IsAjaxRequest) ]
