Create "Inlines"-Property for custom TextBlock-Control?

Question

Hello!

I've created my own custom TextBlock-Control, which works so far and now I would like to add "Run"-Elements to the Inlines-Property in codebehind. But the Inlines-Property don't exist in my control at the moment and my question is, what I must do to have the same property and behaviour in my control?

Here is my code:

using System.Windows.Controls;
using System.ComponentModel;
using System.Windows;

namespace My_Controls.Controls
{
    [Description("Textblock BaseClass"), Category("Common Properties")]
    public class My_TextBlock : Control
    {
        public My_TextBlock()
        {
            this.DefaultStyleKey = typeof(My_TextBlock);
            this.FontFamily = new System.Windows.Media.FontFamily("Arial");
            this.FontSize = 11;
      
        }


        public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string), typeof(My_TextBlock), new PropertyMetadata(" "));

        [Description("Text Property."), Category("Common Properties")]
        public string Text
        {
            get { return GetValue(TextProperty) as string; }
            set { SetValue(TextProperty, value); }
        }

        public string Content
        {
            get
            {
                return this.Text;
            }
            set
            {
                this.Text = value;
            }
        }

        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();
        }
    }
}

Thank you in advance for your answers!

i Malone,
As we all know that the TextBlock Inlines property is not a DependencyProperty. So we can't bind it in the code behind directly. You can create inlines property through an attached property and Data Binding converter.
