Creating a textbox in xaml through xaml.cs code

Question

I want to create textboxes in xaml file upon a button click through the .xaml.cs file from a loop (probably). I've calculated the margins for each textbox to appear in the panel but do not know how to bind the code. Here's the image of the xaml design view and what I'm trying to achieve. The window will have one textbox for choices appear and the loop will create another and another each time the add choice button is clicked.

Can anyone please help? I'm just learning wpf. Thank you

what mean by **bind the code**? recommend a book [Applications = Code + Markup](http://www.charlespetzold.com/wpf/) — Lei Yang, Dec 06 '16 at 01:12
@LeiYang I mean the code in the .xaml.cs file should create a corresponding action in the .xaml file — Elizabeth Ekefre, Dec 06 '16 at 01:17
Searched but can't find anything about creating a new component from the cs code. Honestly have no clue how to go about it. Any hint or example or anything would be helpful — Elizabeth Ekefre, Dec 06 '16 at 01:40
@LeiYang The link you gave isn't the full book. I'd have to buy it? — Elizabeth Ekefre, Dec 06 '16 at 01:55
@ElizabethEkefre: I posted an answer to guide you. Use the Children property of the panel — Max, Dec 06 '16 at 02:29

Assuming by Bind the code you mean how to add the TextBox to the panel. To do that, you need to add the textboxes to the Children property of the panel.

If you need to do this upon initialization of your form, then just place your code after InitializeComponent(); in the form constructor.

Here's an example how to do this programatically, responding to a click event:

Xaml:

<StackPanel Name="pn_Content" Orientation="Vertical">
    <Button Click="btn_Add_TextBox_Click">Add Textbox</Button>
</StackPanel>

C#:

private void btn_Add_TextBox_Click(object sender, RoutedEventArgs e) {
   TextBox tb = new TextBox();
   tb.Height = 23;
   tb.Width = 100;
   pn_Content.Children.Add(tb);
}

and that's it.

Thanks alot I just needed that little example for guidance :] really helped — Elizabeth Ekefre, Dec 06 '16 at 03:02

First, place all the current text boxes in a container, for example a stack panel named stackPanel. Then add your controls to the Children of the panel:

stackPanel.Children.Add(new TextBox { Text = "TextBox" });
