DataGridView单元格编辑时,按上下方向键无法触发KeyDown事件,各位大哥大姐帮帮忙

源码如下：
       private DataGridViewTextBoxEditingControl EditingControl = null;

        private void dgvMain_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {

            if (this.dgvMain.CurrentCell.RowIndex > -1)
            {
                if (e.Control is DataGridViewTextBoxEditingControl)
                {
                    this.EditingControl = (DataGridViewTextBoxEditingControl)e.Control;
                    //增加委托处理
                    this.EditingControl.KeyDown += new KeyEventHandler(this.EditingControl_KeyDown);
                }

            }

        }

        private void EditingControl_KeyDown(object sender, KeyEventArgs e)
        {
           //业务处理
           //按上下键时就是不触发该事件
        }

        private void dgvMain_CellEndEdit(object sender, DataGridViewCellEventArgs e)
        {
            if (this.EditingControl != null)
            {
                EditingControl.KeyDown -= new KeyEventHandler(this.EditingControl_KeyDown);
                this.EditingControl = null;
            }
        }

高手了??
哪位老大给点提示

#2

PreviewKeyDownEvent 可以触发上下键的事件



this.EditingControl.PreviewKeyDown += new PreviewKeyDownEventHandler(this.EditingControl_PreviewKeyDownEvent);

this.EditingControl.KeyDown += new KeyEventHandler(this.EditingControl_KeyDown);


private void EditingControl_PreviewKeyDownEvent(object sender, PreviewKeyDownEventArgs e)

{

    //业务处理 

    //按上下键时触发该事件 

}


private void EditingControl_KeyDown(object sender, KeyEventArgs e)

{

    //MessageBox.Show("dsdss");

    //业务处理 

    //按上下键时就是不触发该事件 

}
