MessageBox appearing twice on clickevent

I have this code here, When I click on the Modify button, I got a message box. After I click on the x button to close it, the message box appears again. I really don't know why this happens.

private void dataGridUsers_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (dataGridUsers.Columns[e.ColumnIndex] is DataGridViewButtonColumn &&
        e.RowIndex >= -1 && dataGridUsers.Columns[e.ColumnIndex].Name == "Modify")
    {
        MessageBox.Show("");
    }
}

My Guess: You are re-assigning the event handler again and again somewhere in your code. That is the problem you are getting the message box triggered twice.

dataGridUsers.CellContentClick += new DataGridViewCellEventHandler(dataGridUsers_CellContentClick);

To fix the issue, you need to assign the above event handler only in the function where you need.
