Hi,
Go to the checked changed event of your checkbox and disable the RequireFieldValidator(make sure the AutoPostBack property of your CheckBox is set to true). Try this:

C#

protected void checbox1_CheckChanged(object sender, EventArgs e)
{
    if(checkbox1.Checked)
    {
        //Suppose your first name RequiredFieldValidator's id is RequiredFieldValidator1
        //And your last name RequiredFieldValidator's id is RequiredFieldValidator2
        RequiredFieldValidator1.Visible = false;
        RequiredFieldValidator2.Visible = false;
    }
    else
    {
        RequiredFieldValidator1.Visible = false;
        RequiredFieldValidator2.Visible = false;
    }
}

Hi

There is another solution you can try (if you want to make this all in client side ) with custom validator. In the validation function you can check if the check box is checked or not and then check your field based on the check.

Please see the link and go to "Custom Validator" Section

Hope this will help you.
