How to force datagridviewcell to end edit when row header is clicked
提问by l46kok
I am trying to force the DataGridViewCellto exit out of the edit mode when a user clicks the row header that's in the same row as the cell being edited. For the record, editmode is set to EditOnEnter.
DataGridViewCell当用户单击与正在编辑的单元格位于同一行的行标题时，我试图强制退出编辑模式。对于记录，editmode 设置为 EditOnEnter。
So I write the following event accordingly:
所以我相应地写了以下事件：
private void dGV_common_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
dGV_common.EndEdit();
}
The above code didn't force the cell to end the edit mode. While the below code forces the cell to exit from editmode:
上面的代码没有强制单元格结束编辑模式。虽然下面的代码强制单元格退出编辑模式：
private void dGV_common_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
dGV_common.EndEdit();
dGV_common.CurrentCell = null;
}
It also deselects the entire row, which is not the desired behavior when a user clicks on the RowHeader.
它还取消选择整行，当用户单击RowHeader.
So, my work around has been the following:
所以，我的工作如下：
private void dGV_customer_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
dGV_customer.EndEdit();
dGV_customer.CurrentCell = null;
dGV_customer.Rows[e.RowIndex].Selected = true;
}
Which works well when you select a single row header, but fails when you try to select multiple row headers by holding shift.
当您选择单个行标题时效果很好，但当您尝试通过按住 shift 选择多个行标题时失败。
How can I properly handle this situation?

i ran into exactly the same problem this week! it appears this is a pretty well documented bug in the datagridview. i'm unsure if it's been fixed in any later versions. checking for a row header when the grid is clicked and changing the editmode seems to work though:
这周我遇到了完全相同的问题！看来这是datagridview 中一个很好记录的错误。我不确定它是否已在任何更高版本中修复。单击网格时检查行标题并更改编辑模式似乎有效：
private void dataGridView_MouseClick( object sender, MouseEventArgs e ) {
DataGridView dgv = (DataGridView)sender;
if (dgv.HitTest(e.X, e.Y).Type == DataGridViewHitTestType.RowHeader) {
dgv.EditMode = DataGridViewEditMode.EditOnKeystrokeOrF2;
dgv.EndEdit();
} else {
dgv.EditMode = DataGridViewEditMode.EditOnEnter;
}
}
however this is still an irritating work around if you use many datagridviews throughout your application, so let me know if you discover a better solution.
但是，如果您在整个应用程序中使用许多 datagridviews，这仍然是一个令人讨厌的工作，所以如果您发现更好的解决方案，请告诉我。

I found a easy fix to disable editmode:
我找到了一个简单的方法来禁用编辑模式：
SendKeys.Send("{TAB}");
SendKeys.Send("+{TAB}");
It simply presses tab, and then shift+tab
它只是按下tab，然后shift+tab
