Question

I have a Datagridview which populates caller number and called number, upon selecting the two column values, and click a button a message box should display the selected column values. How this can be achieved. Any sample code would be of great help.

Answer 1

You should take a look at DataGridView’s SelectedCells property. Your button click method can do something along those lines then:

private void button_Click(object sender, EventArgs e)
{
    StringBuilder message = new StringBuilder();
    foreach (DataGridViewCell cell in this.dataGridView.SelectedCells)
    {
        message.AppendLine("Value = " + cell.Value);
    }

    MessageBox.Show(message.ToString());
}

This will display all values of selected cells in message box.
