推荐答案

（从我的头顶，我认为这是WinForms控件）

(From the top of my head, I assume this is for the WinForms controls)

你需要有两个RepositoryItem，一个没有清除按钮，另一个使用按钮（你可以通过RepositioryItem的Buttons属性添加按钮）。

You'll need to have two RepositoryItems, one without the clear button, and one with the button (you can add buttons via the RepositioryItem's Buttons property).

你会将RepositoryItem分配给相关列的附加按钮。

You'll assign the RepositoryItem without the additional button to the relevant column.

然后，您需要处理GridView的CustomRowCellEditEventHandler。检查事件的e.RowHandle是否等于GridControl.AutoFilterRow，如果是，则使用清除按钮将e.RepositoryItem分配给RepositoryItem。

Then you'll need to handle the GridView's CustomRowCellEditEventHandler. Check if the event's e.RowHandle equal GridControl.AutoFilterRow, and if so, assign e.RepositoryItem to the RepositoryItem with the clear button.

然后处理清除按钮RepositoryItem的ButtonClicked事件。

Then handle the clear button RepositoryItem's ButtonClicked event.
