Hi Shanker,

Please  remove the IsPostback checking in the PreRender event of the grid. You also  need to rebind the grid in order for the grid to be in edit mode.

Thanks,
Princy

Hi,

this is shanker am doing application my requirement is catch the databound value in Itemdatabound event in GridEditable mode I am write this code 

protected void fulldaygrid_ItemDataBound(object sender, GridItemEventArgs e)
        {
            int? student_absence_id = null;

            if ((e.Item is GridEditableItem || e.Item is GridDataItem) && e.Item.IsInEditMode)
            {



                GridEditableItem editedItem = (GridEditableItem)e.Item;
                int item = editedItem.ItemIndex - 1;
                    student_absence_id = editedItem.OwnerTableView.Items[item].Cells[1].ToString().GetInteger();
                    //int? eventId = GetEventId(e.Item);
                    if (student_absence_id.HasValue)
                    {
                        var det = studentattendancemanager.sch_view_student_absence_single_day_detail(student_absence_id);



                        //Label lblStudentname = e.Item.FindControl("lblStudentname") as Label;
                        //if (lblStudentname != null)
                        //{
                        //    string Name = det.first_name + det.last_name;
                        //    lblStudentname.Text = Name;
                        //}
                        //Label lblStudentNumber = e.Item.FindControl("lblStudentNumber") as Label;
                        //if (lblStudentNumber != null)
                        //{
                        //    lblStudentNumber.Text = det.student_number;
                        //}

                        TextBox txtDescription = e.Item.FindControl("txtDescription") as TextBox;
                        if (txtDescription != null)
                        {
                            txtDescription.Text = det.description;
                      }


                }   
            }
        }
