Question

what is the purpose of command name and command argument for a control example button? when should we go for this?

Answer 1

The Command event makes it easy to write a single method that handles the clicks of multiple buttons.

protected void Button_Command(object sender, CommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "Back":
            FeedbackLabel.Text = "Back";
            break;
        case "Up":
            FeedbackLabel.Text = "Up";
            break;
        case "Forward":
            FeedbackLabel.Text = "Forward";
            break;
    }
}
