vb.net change datagridview column type to combobox
提问by Hilal Al-Rajhi
can I change textbox column in datagridview in vb.net to combobox column type at run time? I know that can be done in design time but I want to do that programatically.
我可以在运行时将 vb.net 中 datagridview 中的文本框列更改为组合框列类型吗？我知道这可以在设计时完成，但我想以编程方式完成。

If you are in runtime you will have to remove the column and then add a combobox column. Make sure that the Items list of your combobox contains the data value or an exception will be thrown.
如果您在运行时，则必须删除该列，然后添加一个组合框列。确保组合框的项目列表包含数据值，否则将引发异常。
With DataGridView1
If .Rows.Count = 0 Then Exit Sub
i = Datagridview1.currentrow.index
Dim gridComboBox As New DataGridViewComboBoxCell
gridComboBox.Items.Add("A") 'Populate the Combobox
gridComboBox.Items.Add("B") 'Populate the Combobox
gridComboBox.Items.Add("C") 'Populate the Combobox
.Item(8, i) = gridComboBox
End With
