ASP.NET Wizard not moving to WizardStep index 3 in browser

Question

I have a web feedback wizard and when I tested it in the browser, clicking the next button, it goes fine from step 1 to step 2 but then it refuses to go to step 3. Also, I tried to keep the focus on the first text box in each step, but it still isn't working right. when I click 'next' the step moves (as i said it works from Contact Info to Comments) but it scrolls up to the top of the web page and loses focus from the wizard. which is annoying. so I have two problems: (1) my wizard only goes to two out of the four steps. (2) the wizard loses its focus.

here is what i have in my wizard control:

  
    
    
    
    
    
    
        
            
                
                    
                        Your Name
                    
                        
                    
                    
                        
                    
                
                
                    
                        Email
                    
                        
                    
                    
                        
                    
                
                
                    
                        City
                    
                        
                    
                    
                        
                    
                
                
                    
                        State

                                                          Thank You!

here is what i have in the behind code: (c#)

protected void Page_Load(object sender, EventArgs e)
   {

    //Prevent display of sitemap on default page.
    SiteMapNode node = SiteMap.CurrentNode;

    if (node.ParentNode == null)
    {
        SiteMapPath1.Visible = false;
        Wizard1.Visible = false;
    }

    nameLabel.Text = nametxt.Text;
    EmailLabel.Text = emailtxt.Text;
    cityLabel.Text = citytxt.Text;
    stateLabel.Text = statebox.Text;
    commentslabel.Text = txtcomments.Text;
    ratinglabel.Text = txtrating.Text;

}


 public void OnNextButtonClick(object sender, WizardNavigationEventArgs e)
  {

        this.Wizard1.Focus();
        Wizard1_ActiveStepChanged(sender, e);

   }




   private TextBox FindFirstTextBox(Control c)
     {

    TextBox nothing = null;
    Control results;

    if ((c == null))
    {
        return nothing;
    }

    if (c.GetType() == typeof(TextBox))
    {
        return (TextBox)c;
    }




    foreach (Control child in c.Controls)
    {
      results = FindFirstTextBox(child);

      if (results != null && (results.GetType() == typeof(TextBox)))
      {
          return (TextBox)results;

      }
      else
      {

          return nothing;
      }


     }

    return nothing;

}

protected void Wizard1_ActiveStepChanged(object sender, System.EventArgs e)
{
    // Set the focus to the first TextBox in the current step
    WizardStepBase currentWizardStep = Wizard1.ActiveStep;
    // Find the first TextBox
    TextBox firstTextBox = FindFirstTextBox(currentWizardStep);
    // If we found a TextBox, set the Focus
    if (!(firstTextBox == null))
    {
        firstTextBox.Focus();
    }
}

Ok that is because... you have a compare validator on your txtComments field in the 2nd step of your wizard...I would recommend to either fix it or remove it...here is the code that I am referring to (in your Wizard Step 2)

The things that are missing in the above code are:

Set "ControlToCompare" property.
Set an error message...

Update for your second problem

To keep focus on your first text box...of each tab and to keep scroll position...follow below steps...

Step 1 In your Page_Load event...add the below line of code

nametxt.Focus(); // This will make sure that your nametxt texbox has focus when your page loads for the first time

Step 2 Your FindFirstTextBox method's code can be as simple as below...so update it to the code below...

// This code is pretty much self explanatory    
private TextBox FindFirstTextBox(Control c)
        {
            foreach (Control child in c.Controls)
            {
                if (child is TextBox)
                    return (TextBox)child;
            }

            //If we didn't find a TextBox
            return null;
        }

Step 3 Update your Wizard_ActiveStepChanged event to below...

protected void Wizard1_ActiveStepChanged(object sender, System.EventArgs e)
        {
            // Set the focus to the first TextBox in the current step
            WizardStepBase currentWizardStep = Wizard1.ActiveStep;

            // Find the first TextBox
            TextBox firstTextBox = FindFirstTextBox(currentWizardStep);
            // If we found a TextBox, set the Focus               

            if (Page.IsPostBack && firstTextBox != null)
            {
                firstTextBox.Focus();
            }
        }

In the above event code, I have changed the if statement to have an additional check for page.IsPostBack...this is because the Focus method will throw an exception...since this event is being called before your OnLoad and OnRender...Its pretty much up to you to figure out why you are calling this step so early...

Step 4 Finally, to fix your scrolling problem...you need to use an Update panel...please see below code snippet...

 // Your Update Panel needs a Script Manager to work    
    
        
        

        // ALL YOUR CONTENT MARK UP GOES HERE

This should probably fix your second problem...
