{
DataGridViewRow dataGridViewRow1 = dataGridView1.Rows[e.RowIndex];
toolStripMenuItem1.Enabled = true;
// Show the appropriate ContextMenuStrip based on the employees title.
if ((dataGridViewRow1.Cells["Title"].Value.ToString() ==
"Sales Manager") ||
(dataGridViewRow1.Cells["Title"].Value.ToString() ==
"Vice President, Sales"))
{
e.ContextMenuStrip = managerMenuStrip;
}
else
{
e.ContextMenuStrip = employeeMenuStrip;
}
contextMenuRowIndex = e.RowIndex;
}
Public Sub dataGridView1_RowContextMenuStripNeeded( _
ByVal sender As Object, _
ByVal e As DataGridViewRowContextMenuStripNeededEventArgs) _
Handles dataGridView1.RowContextMenuStripNeeded
Dim dataGridViewRow1 As DataGridViewRow = _
dataGridView1.Rows(e.RowIndex)
