Question

在datagridView中加入一个combox列，怎么能允许用户输入

Answer 1

解决办法如下：

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (dataGridView1.CurrentCell.ColumnIndex == 3) //这里需要你具体的列索引
{

DataGridViewComboBoxEditingControl editCtrl = e.Control as DataGridViewComboBoxEditingControl;
editCtrl.DropDownStyle = ComboBoxStyle.DropDown; //变为这样的下拉风格
}

}
