[Solved] Set DialogResult from UserControl

[Mike Hanson]

I am using RadWindow to display property dialogs for entities in my application, these are created in code using an extension method of my application.

Is there a built in way for the content set for a RadWindow to detect the window in order to set the DialogResult and Close it?

I'm not sure about the DialogResult, but here's my code to close a window from within itself:

/// <summary>
/// Recurses through the parent objects and looks for a RadWindow. If it is found, it is closed.
/// </summary>
public void CloseParentPopup(DependencyObject obj)
{
    RadWindow win = CommonFunctions.GetParentOfSpecificType(obj, typeof(RadWindow)) as RadWindow;
    if (win != null)
        win.Close();
}

And you call it like this in any usercontrol:

CloseParentPopup(this as DependencyObject);

Sorry, forgot the helper function. This should be put in the static class CommonFunctions

/// <summary>
/// This recurses the visual tree for a parent of a specific type
/// </summary>
/// <param name="parent"></param>
/// <param name="targetType"></param>
public static DependencyObject GetParentOfSpecificType(DependencyObject parent, Type targetType)
{
    while (parent != null)
    {
        parent = VisualTreeHelper.GetParent(parent);
        if (parent.GetType() == targetType || parent.GetType().BaseType == targetType)
        {
            return parent;
        }
    }

    return null;
}
