  1. POHow can I add a nested design-time property to a user control?
    text
    copied!<p>I have a user control that contains a number of panel controls. The user control has logic to set the visibility of each panel, based on the values of some variables contained in the user control.</p> <p>I would like to enhance this functionality by adding the following enumeration:</p> <pre><code>public enum Visibility { Default, Always, Never } </code></pre> <p>where <code>Default</code> would use the current logic to set the panel's visibility, but <code>Always</code> would (obviously) make the panel always visible, and <code>Never</code> would always hide the panel.</p> <p>I would also like to add a "nested" design-time property named something like <code>PanelVisiblity</code> that the developer could expand, and see the panel names listed below, and allow them to assign a value from the <code>Visibility</code> enumeration for each.</p> <p>If I add properties like this:</p> <pre><code>public partial class MyControl : UserControl { public Visibility ActivePanel { get; set; } public Visibility CodePanel { get; set; } } </code></pre> <p>the <code>ActivePanel</code> and <code>CodePanel</code> properties appear in the Properties window in Visual Studio, and I can set them to one of the three values in the enum. However, when I refactored my code to try to create a nested property like this:</p> <pre><code>public partial class MyControl : UserControl { public class PanelVisibility { public enum Visibility { Default, Always, Never } public Visibility ActivePanel { get; set; } public Visibility CodePanel { get; set; } } } </code></pre> <p>I do not get an expandable <code>PanelVisiblity</code> property, I get a disabled <code>Visiblity</code> property, where the value is the namespace of class, plus 'PanelVisibility'.</p> <p>I have Googled a number of variations in phrasing this search, but have not been able to find anything like what I'm looking for.</p> <p>Any direction would be greatly appreciated.</p>
