Trying the menustrip-thing as a parameter in the DoWork method Smile | :)

private ContextMenuStrip contextMenuStrip1;

public Form1()
{
    InitializeComponent();
    dataGridView1.RowContextMenuStripNeeded += dataGridView1_RowContextMenuStripNeeded;
    dataGridView1.SelectionChanged += dataGridView1_SelectionChanged;

    contextMenuStrip1 = new ContextMenuStrip();
    contextMenuStrip1.Items.Add("The turtle moves.");
}

void dataGridView1_SelectionChanged(object sender, EventArgs e)
{
    DoMyBidding(null);
}

void dataGridView1_RowContextMenuStripNeeded(object sender, DataGridViewRowContextMenuStripNeededEventArgs e)
{
    e.ContextMenuStrip = contextMenuStrip1;
    int selectedrowindex = e.RowIndex; // why not dataGridView1.SelectedRows[0].Index?

    DoMyBidding(e.ContextMenuStrip);
}

void DoMyBidding(ContextMenuStrip humbly)
{
    // do whatever you normally do?
}

M.D.V.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.
