Why is the Dependency Property not returning its value?
- by B-Rad
I have a MyUserControl with the following Xaml:
<TextBox Text="{Binding InputValueProperty}" />
In the MyUserControl.xaml.cs I have:
public string InputValue
{
get { return (string)GetValue(InputValueProperty); }
set { SetValue(InputValueProperty, value); }
}
public static readonly DependencyProperty InputValueProperty =
DependencyProperty.Register("InputValueProperty", typeof(string),
typeof(MyUserControl));
In my MainWindow.xaml I create a user control:
<local:MyUserControl InputValue="My Input" />
Later on in my MainWindow.xaml.cs I am trying to access this string. All instances of MyUserControl are contained in a List and I access them with a foreach.
string temp = userControl.InputValue;
This is always null. In my MainWindow.xaml I can see the "My Input" in the text box of the user control but I can't ever seem to get it out of there.
