将TextBox文本传递给导航页面

Question

I am trying to pass data from a textbox in one page to a text block in the navigated page. I have some code but I am finding an error when running it here is my coding.

From the page I want to send the data from:

 private void button1_Click(object sender, RoutedEventArgs e)
        {if (txtSID.Text != null)
            {
                string StudentID = txtSID.Text;


                var url = string.Format("/BookingConf.xaml?StudentID={0}", StudentID);
                NavigationService.Navigate(new Uri(url, UriKind.Relative));
            }

Code from the Navigated Page:

   protected override void OnNavigatedTo(NavigatingEventArgs e)
    {
        String StudentID;

        if (NavigationContext.QueryString.TryGetValue
            ("studentID", out StudentID))
        {// load event data, and set data context
            ReferanceST.Text = StudentID;
        }
    }

The issue is that when I run the application I get an error on the 'OnNavigationTo(NavigationEventArgs e)' saying no suitable method found to override. In order to fulfil this i placed the 'if' statement but it made no difference.

Please help me resolve this issue. Thank you.

Answer 1

The error is happening because you miss named the override method.

The error is the smoking gun

"no suitable method found to override"

To fix this

 protected override void OnNavigationTo(NavigatingEventArgs e)
    {

should be

 protected override void OnNavigatedTo(NavigatingEventArgs e)
    {

MSDN Reference

Answer 2

The OnNavigatingTo takes the NavigationEventArgs, not the NavigatingEventArgs.

Change your line to:

protected override void OnNavigatedTo(NavigationEventArgs e)
