            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;

                        //}

Hello shanker,

If the field name you need to get is called student_absence_id and it is added to the DataKeyNames of the respective GridTableView, you can use:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = (GridEditableItem)e.Item;
        int student_absence_id = (int)item.GetDataKeyValue("student_absence_id");
    }
}

Alternatively, you can get the column editor using the column unique name:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = (GridEditableItem)e.Item;
        GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("student_absence_id");
        int student_absence_id = Int32.Parse(editor.Text);
    }
}

Hello Shanker,

Have you set the 'DataKeyNames' property as your field 'student_absence_id' in MasterTableView?

ASPX:

 <MasterTableView DataKeyNames="student_absence_id" DataSourceID="SqlDataSource1" ..

Thanks,

Princy.
