Working with selectors Part One: Content selector, Image selector, Document selector.

by User Not Found


I'm going to start a session of some posts about selectors in Sitefinity. There won't be a lot of coding, because I will describe some general aspects of the topic. In this post I will work with user control and selectors will be set as a properties of this control.

We will define selectors in the code behind of our user control.

1. Content selector.


Content Selector

As a result the Guid of a selected item will be returned. You can browse from Generic_Content, News,

Blogs, Images and Documents, Events.

#region Properties
 //content selector 
    [WebEditor("Telerik.Cms.Engine.WebControls.ContentSelector, Telerik.Cms.Engine")]
 public Guid SelectContent
 return this.selectContent;
 this.selectContent = value;
 //declare Provider Name property 
 public virtual string ProviderName
 return this.providerName;
 this.providerName = value;
 private Guid selectContent;
 private string providerName = string.Empty;


2. Image and document selectors



Image selector



Document Selector


 //image selector 
    [WebEditor("Telerik.Libraries.WebControls.ImageSelector, Telerik.Libraries")]
 public string SelectImage
        { return this.image; }
        { this.image = value; }
 private string image;
 //document selector 
   [WebEditor("Telerik.Libraries.WebControls.DocumentsSelector, Telerik.Libraries")]
 public string SelectDoc
        { return this.doc; }
        { this.doc = value; }
 private string doc;




Coming soon Part 2 - file manager selector, page id selector, rss feed selector

    Very usefull post. Thanks Ivan
    I have one query about ContentSelector eidtor. Here using dropdown we can select content of type Generic Content, News, Blogs, Images and Documents, Events, etc. Basically contents from all the Generic Content Based modules. Now if I want to restrict the user to News items only. Can I do this? I mean dropdown should only show News. Or atleast News should be selected by default. Is it possible? and How?

    Extremely useful post. We find that content managers will often change the name of an image or document effectively break the link these 2 selectors return. Is there anyway to have the Image and Doc selectors to a return a Guid so that this doesn't happen? Thanks

    I am trying this in VB and it does not work. What are you importing? Anything else I need to be aware of? Thanks

    I'm trying to do something similar with a custom control that I'm building.  I'm using the ImageSelector WebEditor but it always returns the GUID of the image and not the actual  URL like you have here.  I'm using 3.6 SP1.  Has something changed in the new version that affects this?

    Every time I try selecting another content type (from Generic to News or Events or Blogs, etc) I consistently get this blog error.. no matter which content type I'm trying to grab. Any ideas on what this is??

    Multiple controls with the same ID 'BlogsDataSource' were found. FindControl requires that controls have unique IDs.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Exception Details: System.Web.HttpException: Multiple controls with the same ID 'BlogsDataSource' were found. FindControl requires that controls have unique IDs.
