  Hi,
  
  I'm trying to create a custom control by Inheriting the ImageGallery Control. To give you a basic form of what i'm doing without getting into the full detail. I am currently trying to pass a parameter via the URL and use it to filter for all Images with certain tag.
  
  Currently All i'm getting is a table appearing with two cells, one with the text "Title" and the other "Szie". The template ascx file that I am using does not have this HTML in there, its got "nothing" like this. SO not sure what is going one. Any help would be appreciated.
  
  Thanks in advance,
  
  Joel

  Hi joeldickson,
  
  The problem is that you are calling the base class instead of overriding layouttemplatePath property. Please take a look at the code below:
  
  

  using System;

  using System.Collections.Generic;

  using System.Linq;

  using System.Web;

  using Telerik.Libraries.WebControls;

  /// <summary>

  /// Summary description for CustomImageGallery

  /// </summary>

  public class CustomImageGallery : ImageGallery

  {

  public CustomImageGallery()

  {

  //

  // TODO: Add constructor logic here

  //

  }

  public override string ItemListTemplatePath

  {

  get

  {

  return "relative path to your template";

  }

  }

  public override Type LocalizationAssemblyInfo

  {

  get

  {

  return typeof(ImageGallery);

  }

  set

  {

  base.LocalizationAssemblyInfo = value;

  }

  }

  protected override void CreateChildControls()

  {

  base.CreateChildControls();

  this.GalleryTemplateMode = GalleryViewMode.Lightbox;

  this.BehaviorMode = BehaviorModes.Master;

  }

  }

  Hi joeldickson,
  
  LightBoxListTemplatePath is obsolete and it is no more in use. Override ItemListTemplatePath. When you override ItemListTemplatePath it is not possible to get the same result, because you implicitly set the path in the custom control.

  Hi Ivan,

  Thanks for that, I found this post.

  http://www.sitefinity.com/support/forums/sitefinity-3-x/developing-with-sitefinity/problem-with-imagegallery-in-version-3-6.aspx

  I was having this problem as well.

  Now I've hit another wall i need help with.

  I need to programmatically filter this images.

  this.TagItemKey = "test1";

  Inside the create child controls overide. ANd its not filtering at all.

  Should i be using the text name of the tag or the GUID? And do i have to call a method after this to Bind it? am i doing this the right way?

  Thanks in Advance Ivan, ur a Champ.

  Joel

  Hello joeldickson,
  
  You can override the method below and use ContentFilterBuilder.
  
  

  protected override System.Collections.IList CreateDataSource()

  {

  var builder = new ContentFilterBuilder(this);

  builder.AddFilter(new ContentFilterStatement("Tag.Name", "test", Telerik.Cms.Engine.ContentViewFiltering.ContentFilter.Condition.Equal));

  return base.CreateDataSource();

  }

  
  TagItemKey property can be overridden or directly hard coded.
  
  

  public override string TagItemKey

  {

  get

  {

  object tagKeyObj = this.ViewState["TagKey"];

  if (tagKeyObj == null)

  return LibraryManager.GalleryTagKey;

  return (string)tagKeyObj;

  }

  set

  {

  this.ViewState["TagKey"] = value;

  }

  }

  ....

  ...

  protected override System.Collections.IList CreateDataSource()

  {

  var builder = new ContentFilterBuilder(this);

  builder.AddFilter(new ContentFilterStatement("Tag.Name", "test", Telerik.Cms.Engine.ContentViewFiltering.ContentFilter.Condition.Equal));

  // directly set the property

  //TagItemKey = "key?";

  return base.CreateDataSource();

  }
