Button not working - launching a webpage from a button in C#

Hello Everyone, I made a form (WPF User Control) with a textbox called Tracking_Num, a comboBox called Courier_List, and a button called Tracking_Button. The idea is the user selects a courier, enters the tracking number, and hits track to launch the default browser and track the package using the provided courier and tracking #.
 
The button is completely not working - nothing happens when I click it not even an error.
 
Here is my XML code:
<ComboBox x:Name="Courier_List" Margin="102,363.711,83,125.874" ItemsSource="{Binding Path=Courier_List, Mode=Default, UpdateSourceTrigger=PropertyChanged}" >
        <ComboBoxItem x:Name="UPS" Content="UPS"/>
        <ComboBoxItem x:Name="FedEX" Content="FedEX"/>
        <ComboBoxItem x:Name="UPS_SCS" Content="UPS SCS"/>
</ComboBox>
 
<TextBox x:Name="Tracking_Num" Margin="102,393.2,83,96.237" Text="{Binding Path=Tracking_Num, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
 
<Button x:Name="Tracking_Button" Content="Track!" HorizontalAlignment="Left" Margin="284.6,393.2,0,0" VerticalAlignment="Top" Width="75" Height="24.8" Click="Tracking_Button_Click">

Here is my C# code:
<ComboBox x:Name="Courier_List" Margin="102,363.711,83,125.874" ItemsSource="{Binding Path=Courier_List, Mode=Default, UpdateSourceTrigger=PropertyChanged}" >
        <ComboBoxItem x:Name="UPS" Content="UPS"/>
        <ComboBoxItem x:Name="FedEX" Content="FedEX"/>
        <ComboBoxItem x:Name="UPS_SCS" Content="UPS SCS"/>
</ComboBox>
 
<TextBox x:Name="Tracking_Num" Margin="102,393.2,83,96.237" Text="{Binding Path=Tracking_Num, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
 
<Button x:Name="Tracking_Button" Content="Track!" HorizontalAlignment="Left" Margin="284.6,393.2,0,0" VerticalAlignment="Top" Width="75" Height="24.8" Click="Tracking_Button_Click">

the C# code is the same as the XML code.

To launch the browser:
first format your url.

string URL = "https://google.com";
System.Diagnostics.Process.Start(URL);

or you can also do a NavigationWindow:
NavigationWindow nw = new NavigationWindow();
  uri = new Uri("https://google.com", UriKind.Absolute);
  nw.Navigate(uri);
  nw.Show();

My mistake. Here is my C# Code.

I was already using the System.Diagnostics.Process.STart(URL) method but it wasn't working so the first option there has IExplore.exe just for debug purposes (not that it helped).


private void Tracking_Button_Click(object sender, RoutedEventArgs e)
        {

            switch (Courier_List.SelectedValue.ToString())
            {
                case "UPS":

                    System.Diagnostics.Process.Start("IExplore.exe", "http://wwwapps.ups.com/ietracking/tracking.cgi?loc=CA_CA^&tracknum^=" + Tracking_Num.Text.ToString());
                    break;

                case "FedEX":
                    System.Diagnostics.Process.Start("https://www.fedex.com/fedextrack/index.html?tracknumbers^=" + Tracking_Num.Text.ToString() + "^&locale=en_CA^&cntry_code=ca_english");
                    break;

                case "UPS_SCS":
                    System.Diagnostics.Process.Start("https://www.upspostsaleslogistics.com/cfw/trackOrder.do?trackNumber^=" + Tracking_Num.Text.ToString());
                    break;

                default:
                    break;
            }
        }

I ended up fixing this on my own:

private void Tracking_Button_Click(object sender, RoutedEventArgs e)
        {
            var SelectedCourier = Courier_List.SelectedIndex;
            switch (SelectedCourier)
            {
                case 0:
                   
                    try
                    {
                        System.Diagnostics.Process.Start("http://wwwapps.ups.com/WebTracking/track?HTMLVersion=5.0&loc=en_CA&Requester=UPSHome&WBPM_lid=homepage%2Fct1.html_pnl_trk&trackNums=" + Tracking_Num.Text.ToString() + "&track.x=Track");
                    }
                    catch (Exception ex)
                    {
                       MessageBox.Show(ex.Message);
                    }
            
                    break;

                    
                case 1:
                    try
                    {
                        System.Diagnostics.Process.Start("https://www.fedex.com/fedextrack/WTRK/index.html?action=track&action=track&ascend_header=1&clienttype=dotcomreg&mi=n&cntry_code=ca_english&language=english&tracknumbers=" + Tracking_Num.Text.ToString() + "&fdx=1490");
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }
                    break;

                case 2:
                    try
                    {
                    System.Diagnostics.Process.Start("https://www.upspostsaleslogistics.com/cfw/trackOrder.do?trackNumber=" + Tracking_Num.Text.ToString());
                    }
                    catch (Exception ex)
                    {
                       MessageBox.Show(ex.Message);
                    }
                    break;

                //default:
                //    break;
            }
        }

Per http://www.experts-exchange.com/Programming/Languages/C_Sharp/Q_28541134.html#a40393251  the suggestion was to first format the URL and then call the System.Diagnostics.Process.Start.  

Since the code hasn't changed much I can only assume the issue was with how the URL was being formatted.  Had you had used the the https://google.com as an example you would have seen it was an issue with the URL.  I believe full points should be warranted for this.

@Kyle

1. The way the points system is setup, I can't recant the points I awarded (as far as I am aware).

2. If you read the posts thoroughly, you would have discovered I had already been using that format for my strings... I even explicitly said it in my post. The problem was not the format of the URL at all actually, had you read my solution you would realize I used SelectedIndex instead of SelectedValue, and changed the case to match the index # instead of looking for a string match...

3. Your answers literally helped me 0%. I actually requested attention on the topic because it was clear to me the answers were not pointing in the right direction... I had a hunch the problem was in the passing of the selection to the button handler... and I was correct. The only reason I gave you points is for effort, because you took the time to reply to my post. 250 points is more than generous.

I am sorry that you are not pleased with how I marked the solution, I hope that my explanation gave you some insight as to why it was awarded the way it was.

Have a great day and enjoy the rest of your week :)

I have provided points for effort but my solution was done completely independently. Thanks for all your efforts!
