Bill,

Yay!! I'm glad you got it all figured out. I thought you just needed Attributes, but it was just a question of which ones. The Editor attribute was probably the hard one to find, the other ones are pretty straightforward.

>Yep, the article revealed what had to be done. Basically you add design time support by adding custom attributes to the public property, so my Url property with the attributes becomes:

>[Browsable(true), Category("Behavior"), 
 Description("URL to redirect the user to when the count down ends. If this property is blank, no redirection takes place."), 
 DefaultValue(""), Bindable(true), 
 Editor("System.Web.UI.Design.UrlEditor", typeof(System.Drawing.Design.UITypeEditor))]
>    public string NavigateUrl
>    {
>        get { return this._NavigateUrl; }
>        set { this._NavigateUrl = value; }
>}

>>I am not an ASP.NET person at all, but your question got me thinking because it's an interesting and perfectly valid thing to want to do. I figured that you would have to at least look at using Attributes, since they pretty much control design-time stuff. I did a search on MSDN for "attributes NavigateURL", and one of the pages is this:

>>>In the Properties Window for the ASP.NET Hyperlink control, the NavigateUrl property invokes a dialog to select/build the desired Url. I have a Custom Control that has a similar Url custom property string. How do you get the Properties Window interface for the custom property to display the dialog to the user to build the Url? Haven't been able to find anything in the Help or Google on this.
