WPF: Binding items added to UserControl's exposed children
- by Brian
I have a user control that allows items to be added to it by exposing a Grid's Children property. Any control I add shows up fine but when I try to bind a property on the added item to a control in the main window nothing happens (example):
<TextBox Name="txtTest" Text="Success!" />
<mycontrols:CustomUserControl.ExposedGridChildren>
<TextBox Text="{Binding ElementName=txtTest, Path=Text, FallbackValue=fail}"/>
</mycontrols:CustomUserControl.ExposedGridChildren>
This example always results in the TextBox's text showing "fail". Here is how I'm exposing the children in the user control:
public UIElementCollection ExposedGridChildren
{
get { return grdContainer.Children; }
}
Any thoughts? Is it a scope issue? I know I can't name the elements I add to the children because of scope errors. Thanks, Brian.
