你好。我设法做了这样的事情。

首先我尝试使用CellBeginEdit和CellEndEdit，但没有出现ComboBox控件（只是它的可编辑框）。然后我使用了CellClick和CellValidating。它有效，但我必须解决可重入调用问题 - 最后我在网上找到解决方案。

我在这里解释：动态更改DataGridViewTextBoxCell到DataGridViewComboBoxCell

PS

如果您设法使用CellBeginEdit和CellEndEdit，请发布解决方案 - 我很好奇。

Hi. I managed to do something like this.
First I tried with CellBeginEdit and CellEndEdit but the ComboBox control didn't appear (just it's editable box). Then I used CellClick and CellValidating. It worked, but I had to solve the "reentrant call" problem - finally I find the solution on the net.
I explained it here: Dynamically change DataGridViewTextBoxCell to DataGridViewComboBoxCell
P.S.
If you manage to use CellBeginEdit and CellEndEdit, please post the solution here - I'm very curious about it.
