On your click event for the submit button, include some if/then statements that check all of the textboxes to see if they have acceptable values. If you just want to be sure that at least one box has data entered in it, then you could do this:

if (textBox1.Text != "" || textBox2.Text != "" || ...)
{
    // process form submission
}
else
{
    // inform user of missing data
}

If you are doing this client-side, in the web application, your best method will be to use JavaScript to perform the validation when the submit button is clicked. Otherwise the user will have to wait for the server to check the variables and get a new page.
