server side validation

[Bruce]

I'm using the radWizard and on one step, the users enter a bank routing number and an account number.  I have a database table that holds all the valid routing numbers and I would like to validate that what the user entered in a radtextbox is an actual value in the table.  Is there a way to call server-side validation before I navigate to the next step in the wizard?

Hello Weasel,

You can set the Current step as Active in the NextButtonClick and NavigationBarButtonClick events: 

protected void RadWizard1_NavigationBarButtonClick(object sender, WizardEventArgs e)
{
    var wizard = (sender as RadWizard);
    var isCustomValid = CustomServerValidation();
    if (!isCustomValid)
    {
        // prevent step change
        e.CurrentStep.Active = true;
    }
}

private bool CustomServerValidation()
{
    // custom validation
    return false;
}

protected void RadWizard1_NextButtonClick(object sender, WizardEventArgs e)
{
    var wizard = (sender as RadWizard);
    var isCustomValid = CustomServerValidation();
    if (!isCustomValid)
    {
        // prevent step change
        e.CurrentStep.Active = true;
    }
}
