DataGridViewComboBoxColumn用法总结

为DataGridView添加下拉列：

   DataGridViewComboBoxColumn colShow =  
  new DataGridViewComboBoxColumn(); 
  
colShow.Name =  
  " 
  spaceType 
  "; 
  
colShow.HeaderText =  
  " 
  空间类型 
  "; 
  
colShow.Width =  
  200; 
  
colShow.Items.Add( 
  " 
  选项一 
  "); 
  
colShow.Items.Add( 
  " 
  选项二 
  "); 
 

colShow.DisplayIndex = 0;

dataGridView1.Columns.Insert(0, colShow); 

设定值：

dataGridView1.Rows[ 1].Cells[ 2].Value =  " 选项二 ";

设置单击下拉模式(否则需要点两下才能显示下拉框)：

DataGridView属性 EditMode 为 EditOnEnter  
EditingControlShowing += new DataGridViewEditingControlShowingEventHandler(dgv_EditingControlShowing);
