我假设你下寻找这个WinForm的

的ComboBox在DataGridView是可用的编辑控制，你可以通过订阅的EditingControlShowing事件的DataGridView

private void mygrid_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) 
{    
      if (colName == "reqdcolname") 
      { 
       ComboBox cmbox = e.Control as ComboBox; 
       if (cmbox != null) 
       { 
        //subscribe for combobox events as you require 
        cmbox.SelectedIndexChanged -= new EventHandler(cmbox_SelectedIndexChanged); 
        cmbox.SelectedIndexChanged += new EventHandler(cmbox_SelectedIndexChanged); 
        //since it would be call for each combobox cell subscribe in this fashion 
       } 
      } 
}
