  Add a property called ImPath that will open a dialog box for paths in design view?

  Nov 06, 2011 05:22 PM|LINK

  I am developing a custom server control, that will expose a property for specifying the image path. This property is called 'ImPath'. How would I allow a path dialog box to show when a developer is trying to set this property in design view?

  Thanks

  This is easier than I thought. Just follow these 2 steps.

  1. In your custom server control, include the System.Drawing.Design namespace by adding the following line of code at start of your code: using System.Drawing.Design;
  2. The property for which you want to have a URL editor in design view would need to be marked with following 'UrlEditor'attribute. Look at the line below in bold: 

             [Category("Appearance")]
             [Browsable(true)]
             [Description("Path to image to display while page is loading")]
             [Editor("System.Web.UI.Design.UrlEditor", typeof(UITypeEditor))]
             public string LoadingImageUrl
             {
                 get
                 {
                     return _loadingImageUrl;
                 }
                 set
                 {
                     _loadingImageUrl = value;
                 }
             }
