datagridview-如何确定mouseclick事件是否来自单击列标题 [英] datagridview - how to determine if a mouseclick event came from clicking a column heading

问题描述

我有一个datagridview控件，具有SelectionMode = FullRowSelect.此控件还允许单击任何列标题以对任何列进行排序.单击列标题时，将在此控件上触发MouseClick事件，除了datagridview排序外，这导致我的代码的行为类似于再次单击了最后单击的行(焦点"所在的位置).我想区分在网格内发生的MouseClick和在单击列标题时发生的MouseClick.无法弄清楚.我确实添加了ColumnHeaderMouseClick事件，该事件在单击列标题时会在MouseClick事件之外触发，但会在MouseClick事件之后触发(如果在事件触发之前触发，那么我这里有一种解决方法).关于如何确定MouseClick是否在列标题上，或者如何使ColumnHeaderMouseClick首先触发的任何建议?任何帮助是极大的赞赏.谢谢.

I have a datagridview control, with SelectionMode=FullRowSelect. This control also allows any column heading to be clicked to sort any column. The MouseClick event fires on this control when a column heading is clicked, which results in my code acting like the last row that was clicked (where ''focus'' was) is clicked again, in addition to the datagridview sorting. I want to distinguish between a MouseClick that happens within the grid, and a MouseClick that happens when a column heading is clicked. Can''t figure it out. I did add a ColumnHeaderMouseClick event, which does fire in addition to the MouseClick event when a column heading is clicked, but it fires after the MouseClick event (if it would fire before, then I''d have a workaround here). Any suggestions on how to determine if a MouseClick was on a column heading, or how to get the ColumnHeaderMouseClick to fire first? Any help is greatly appreciated. Thanks.

推荐答案

您可以使用 ^ ]事件或 CellClick [ ^ ]事件，您可以使用这两个事件来表示何时单击单元格.无论如何，我不会使用MouseClick事件，因为如果用户双击，则会触发MouseDoubleClick事件.

You can use the CellMouseClick[^] event or CellClick[^] event, either of which you could use to signal when a cell is clicked. I wouldn''t use the MouseClick event anyway because if the user double clicks, the MouseDoubleClick event is fired instead.

我发现，如果我使用cellclick事件，那将允许我检查e.RowIndex，这是mouseclick事件中不可用的值.然后，我可以检查它是否= -1，它标识列标题.问题已解决-谢谢.

What I found was that if I used the cellclick event, that allowed me to check e.RowIndex, which is a value not available in the mouseclick event. Then I can check if it = -1, which identifies a column heading. Problem solved - thanks.
