Binding to Dependency Property of UserControl
posted

I have a UserControl that has a XamNumericEditor as a part of the Tree.

I am trying to set its binding value at runtime and add it dynamically to the children of a control.

This pattern works with TextBox, Button, ComboBox and some other controls. But I can't seem to get it to work with an Infragistic control. Nothing binds to it...but on all the other controls it works.

Please help!

Here is my simplified UserControl XAML

<UserControl x:Class="SilverlightApplication1.XText"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    xmlns:ig="http://schemas.infragistics.com/xaml"         
    d:DesignHeight="300" d:DesignWidth="400">
    
    <Grid x:Name="LayoutRoot" Background="White">
        <ig:XamNumericEditor Name="MyNumericEditor"/>
        
 
    </Grid>
</UserControl>


Here is my code behind

public partial class XText : UserControl
    {
        public XText()
        {
            InitializeComponent();
            MyNumericEditor.SetBinding(XamNumericEditor.ValueProperty,
                new Binding()
                {
                    Source = this,
                    Path = new PropertyPath("MyText"),
                    Mode = BindingMode.TwoWay
                });
        }
 
        public double MyText
        {
            get { return (double)GetValue(MyTextProperty); }
            set { SetValue(MyTextProperty, value); }
        }
 
        public static readonly DependencyProperty MyTextProperty =
            DependencyProperty.Register(
            "MyText", typeof(double), typeof(XText), 
            new PropertyMetadata(null));

}

And when I want to use it




string s = 
@"<uc:XText MyText=""{Binding Path=" + path + @", Mode=TwoWay}""/>";
