DataGridView the right mouse button to select a row

private void Datagridview1_cellmousedown (object sender, DataGridViewCellMouseEventArgs e)
{
if (E.button = = mousebuttons.right)
{
if (e.rowindex >= 0)
{
Datagridview1.clearselection ();
Datagridview1.rows[e.rowindex]. Selected = true;
Datagridview1.currentcell = Datagridview1.rows[e.rowindex]. Cells[e.columnindex];
Contextmenustrip1.show (mouseposition.x, MOUSEPOSITION.Y);
}
}
}
}
The CurrentRow property in DataGridView is read-only and its index cannot be set dynamically, so you can only select rows with the left button in DataGridView, which allows you to locate the current row.
Now to implement the right-click function in DataGridView, the code is as follows:
private void Datagridview1_cellmousedown (object sender, DataGridViewCellMouseEventArgs e)
{
if (E.button = = Mousebuttons.right && e.rowindex >-1 && e.columnindex >-1)
{
dataGridView1.CurrentRow.Selected = false;
Datagridview1.rows[e.rowindex]. Selected = true;
}
}
The DataGridView Cellmousedown event is added as code, and without the comment code, you can implement the uncheck for the currently selected row and select the row for the right mouse click
There is a problem with the CurrentRow property that is still the previous value, even if the selected of the right-click Row is set to true, it cannot be changed.
You can change the properties of the CurrentRow at the same time after you log off the comment code, so it's much easier to encode later.
