MediaContentSelector and Generic Page Selector - Sitefinity - Front- & Back-End Development

I am using the MediaContentSelector and GenericPageSelector on an Add/Edit admin page similar to the intra-site testimonials module that is found in the SDK. Through browsing the forums I came across the following code to insert these on the page.

<li><asp:Label ID="lblBackgroundImage" runat="server" Text="Image" CssClass="sfTxtLbl" />

<asp:Image ID="imgBackgroundImage" runat="server" />

<sf1:MediaContentSelectorView id="selectorView" runat="server"

ContentType="Telerik.Sitefinity.Libraries.Model.Image"

ParentType="Telerik.Sitefinity.Libraries.Model.Album"

LibraryBinderServiceUrl="~/Sitefinity/Services/Content/AlbumService.svc/"

MediaContentBinderServiceUrl="~/Sitefinity/Services/Content/ImageService.svc/" MediaContentItemsListDescriptionTemplate="Telerik.Sitefinity.Resources.Templates.Designers.Libraries.Images.ImageItemDescriptionTemplate.htm"

DisplayResizingOptionsControl="false"

ShowOpenOriginalSizeCheckBox="false">

</sf1:MediaContentSelectorView>

</li>

<li>

<asp:Label ID="lblRelatedLink" runat="server" Text="RelatedLink" CssClass="sfTxtLbl" />

<sitefinity:GenericPageSelector

id="GenericPageSelector1"

runat="server"

RootNodeID="F669D9A7-009D-4d83-DDAA-000000000002"

WebServiceUrl="~/Sitefinity/Services/Pages/PagesService.svc/"

ShowOnlySelectedAsGridOnLoad="true"

MarkItemsWithoutTranslation="true"

AllowMultipleSelection="false" />

</li

My MediaContentSelector is just showing Loading and continues to do so forever and it never shows my image library. The left pane does show my libraries. Is there anything I can do to get it to actually show my images.

My GenericPageSelect is throwing the following error whenever I try to submit the form.

A potentially dangerous Request.Form value was detected from the client (ctl06_GenericPageSelector1_ctl00_ctl00_itemsTreeTable_ctl00_ctl00_treeTable_ClientState="...\n\t\t\t\t<div class=\"sfTreeT...").

I know I can turn off page validation in normal asp.net pages but not sure how I should handle in sitefinity.

So my problem with the Generic Page Selector was solved by disabling page validation. I also figured out why my images in my Media Content Selector is not working. ITs because a javascript method called "sitefinityLocaleFormat()" throwing the error " is not a function".
I did some searching in the forums and there was one post asking something similar so I added a script manager, ajax toolkit scriptmanager, and added [RequireScriptManager] to the class and I am still not having any luck.

Anything I can do to get this error to go away?

Hi Brett,

Can you give me details on the exact javascript code that you are executing and more specifically on the one that is throwing the error?

Its coming from a ScriptResource.axd file. Line 98 of the code below:
