DataGridViewComboBoxColumn用法總結

為DataGridView添加下拉列：

           DataGridViewComboBoxColumn colShow =  
          new DataGridViewComboBoxColumn(); 
          
colShow.Name =  
          " 
          spaceType 
          "; 
          
colShow.HeaderText =  
          " 
          空間類型 
          "; 
          
colShow.Width =  
          200; 
          
colShow.Items.Add( 
          " 
          選項一 
          "); 
          
colShow.Items.Add( 
          " 
          選項二 
          "); 
         

colShow.DisplayIndex = 0;

dataGridView1.Columns.Insert(0, colShow); 

設定值：

dataGridView1.Rows[ 1].Cells[ 2].Value =  " 選項二 ";

設置單擊下拉模式(否則需要點兩下才能顯示下拉框)：

DataGridView屬性 EditMode 為 EditOnEnter  
EditingControlShowing += new DataGridViewEditingControlShowingEventHandler(dgv_EditingControlShowing);
