[C# WPF] Dynamically adding items to content

[James Rose]

Hello gang,

I am playing around with WPF and I cannot find out how to dynamically add multiple items to the Content. I need to have to TextBlocks and two images on a UserControl.

"MenuCount" and "MenuText" are two TextBlocks that are declared within the class and can be modified via properties.

The code I have so far is:

	    public MainPage()
		    : base()
		    {
		    InitializeComponent();
		    DataContext = this;

		    MenuText.Text = "Menu Text";
		    MenuText.FontSize = 20;
		    MenuText.FontFamily = new System.Windows.Media.FontFamily("Courier");
		    MenuText.Margin = new Thickness(300, 0, 0, 0);
		    MenuText.Foreground = this.FontColor;

		    MenuCount.Text = "1 of 100";
		    MenuCount.FontSize = 20;
		    MenuCount.FontFamily = new System.Windows.Media.FontFamily("Courier");
		    MenuCount.Margin = new Thickness(500, 0, 0, 0);
		    MenuCount.Foreground = this.FontColor;

		    MainContent = MenuText;
		    MainContent = MenuCount; //This is where the code is incorrect, obviously.  I need to have both of these items, and two images (not in the code yet) within this. 
	    }
[/CODE]

[CODE]
<UserControl x:Class="BediaMenu.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<StackPanel HorizontalAlignment="Left" Margin="10">
<ContentControl Content="{Binding MainContent}"/>
</StackPanel>
</UserControl>
[/CODE]

Any thoughts?

Can't you just use ContentControl.AddChild?

However, it's considered a bad idea define all markup and styles in C# code. You should make use of the true power of WPF which is its binding and template framework. Since you're only creating static content, you should be fine using a ListBox with a custom ItemTemplate and bind it to the collection to display. That way, you have a beautifully structured MVVM architecture. :)

Check out the MSDN page on ItemTemplate for a good example. You can then further style those ListBoxItems with an ItemContainerStyle.

Thanks for the info Calc

why code stuff in c# and not use the XAML markup?

Besides, those big margins you use.. I think you will have some big problems later when you have more stuff in your window

I have worked with VB for 18 years and C# was the logical next move. I started playing with WPF to get a handle on it's tech and I was testing some of it via code, as opposed to XAML, just to see the process.

I have changed this code to XAML using TextBlocks to display the data., but thanks for the heads up.
