Keep context location change with DatagridView scroll

Question

I have a datagrid View and code is

 DataGridView m_ClientProcessDataGridView = new DataGridView();

And I have a context menu and it is

 ContextMenuStrip contextMenuStripForCells;

on right click on datagrid and showing context menu as

contextMenuStripForCells.Show(m_ClientProcessDataGridView.PointToScreen(e.Location));

The issue is when I scroll datagridview context menu will not move with row position, do we have any idea to keep it move with scroll?

Or can I disable datagridview scroll when context is open ?

Scroll by wheel happens in OnMouseWheel. You can override the method and check if the ContextMenuStrip is open, prevent scroll:

public class MyDataGridView : DataGridView
{
    protected override void OnMouseWheel(MouseEventArgs e)
    {
        if (this.ContextMenuStrip != null && this.ContextMenuStrip.Visible)
            return;
        base.OnMouseWheel(e);
    }
}
