DataGridView item double click
提问by
I have a DataGridView in a Windows Form. I want to handle double click events on each cell to display a detail form related to that record. Unfortunately, the double click event is executed when you double click on column headers. What should I do?

You should check the RowIndexand ColumnIndexproperty of the event arguments. If one of them is negative, it means that either a row header or a column header is clicked, you should ignore that event.
您应该检查事件参数的RowIndexandColumnIndex属性。如果其中一个为负，则表示单击了行标题或列标题，您应该忽略该事件。

What event are you handling? Ideally you should handle the CellDoubleClickor the CellMouseDoubleClickevents and opening your details form in that handler. The latter event will catch a Double click using any of the mouse buttons (the button can be queried using the MouseEventArgs.Buttonproperty.
你在处理什么事件？理想情况下，您应该处理CellDoubleClick或CellMouseDoubleClick事件并在该处理程序中打开您的详细信息表单。后一个事件将使用任何鼠标按钮捕获双击（可以使用MouseEventArgs.Button属性查询按钮。
