I want to extend class TextCell and create class inherrited

 class MyTextCell:TextCell


        public MyTextCell(GridControlBase gridControl, Column column)

            : base(gridControl, column)



        protected override void OnKeyDown(object sender, System.Windows.Forms.KeyEventArgs e)


           //some code



But when i write this code

cellsText[k] = (MyTextCell)dr[k].AddNewCell(typeof(MyTextCell), unboundGridControl1.Columns[0]);

mistake comes out  "Constructor on type ’CSUST.Data.MyTextCell’ not found.."

How can i create correcltly the inherrited of this class?

I create inherited class with two constructors. There are no mistakes now

public class MyCell : TextCell     { public MyCell(GridControlBase gridControl, Column column)     : base(gridControl, column)     {     } public MyCell(Column column, GridControlBase gridControl)     : this(gridControl, column)     {     }     public TextCellStyle Style     {     get     {     return this.Style;     }     }

  protected override void OnKeyDown(object sender, KeyEventArgs e)     {

   // some code     base.OnKeyDown(sender, e);     }



i wanted to created the inherited, in which i can control the quantity of the entered symbols in Text Cell, but i dnt know why the event Key Down is not working??? can anyone advise me how can i do it?

When the cell editor is activated, key events are no longer received by the cell. You should use a custom text editor to handle all the key strokes.
