想办法处理gridControl行中的checkedit事件

想办法处理gridControl行中的checkedit事件：
private void Reorganize()
{
    GridControl gridControl = gridControl1;
    DevExpress.XtraGrid.Columns.GridColumn checkColumn = ((ColumnView)gridControl.Views[0]).Columns["Checked"];
    RepositoryItemCheckEdit et = new RepositoryItemCheckEdit();
    checkColumn.ColumnEdit = et;
    et.CheckedChanged += (s, a) => {
        foreach(System.Data.DataRow dataRow in _vCurrentDataTable.Rows)
        {
            dataRow["Checked"] = false;
        }
 
        //Console.WriteLine("{0}",gridControl.Views.Count);
        //MessageBox.Show(a.ToString()); 
    };
}
