It is really very simple, all that we need is the FrameworkElement and the DependencyProperty that we need refresh. I did some extensions method to update the target or the source of the binding:
public static class BindingExtensions
{
public static void UpdateTarget(
this FrameworkElement element,
DependencyProperty property)
{
BindingExpression expression = element.GetBindingExpression(property);
if (expression != null)
{
expression.UpdateTarget();
}
}
public static void UpdateSource(
this FrameworkElement element,
DependencyProperty property)
{
BindingExpression expression = element.GetBindingExpression(property);
if (expression != null)
{
expression.UpdateSource();
}
}
}
For example if we want to refresh the Text property in a bound TextBox we can do:
textBox.UpdateTarget(TextBox.TextProperty);
