推荐答案

由于.net默认操作也会更新datagridview的slectedrows，你需要有一个数组保留旧选项：





DataGridViewRow [] old;





将在CellMouseDown更新（在默认.net操作修改您的选择之前）：





之后，您可以在RowHeaderMouseClick中进行更改（因为RowHeaderSelect是默认的datagridview选择模式）或使用CellMouseClick进行FullRowSelect并重新选择那些旧的选定行：

As the .net default action will also update the slectedrows of your datagridview you need to have an array to reserve the old selections:


DataGridViewRow[] old;


which will be updated at CellMouseDown (before the default .net action modify your selections):


after that, you can do your changes in RowHeaderMouseClick (as RowHeaderSelect is the default datagridview selectionmode) or use CellMouseClick for FullRowSelect and reselect those old selected rows:

private void dataGridView1_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
    foreach (DataGridViewRow gr in old)
    {
        if (gr == dataGridView1.CurrentRow)
        {
            gr.Selected = false;
        }
        else
        {
            gr.Selected = true;
        }
    }
}
