Yesterday, in order to be able to modify the layouts of some of the RadEditor dialogs, I created the EditorDialogs folder and stuck in a few of the ascx controls that we wanted to change. One was the ImageManager. Basically all I wanted to do with that was to change the overall dialog size since it was cutting off the Cancel and OK buttons.
However when I open up the ImageManager, select an image and then click on Image Editor, I get an error:
Inner Exception: Unknown server tag 'telerik:RadImageEditor'.
at System.Web.UI.TagPrefixTagNameToTypeMapper.System.Web.UI.ITagNameToTypeMapper.GetControlType(String tagName, IDictionary attribs) at System.Web.UI.MainTagNameToTypeMapper.GetControlType2(String tagName, IDictionary attribs, Boolean fAllowHtmlTags) at System.Web.UI.MainTagNameToTypeMapper.GetControlType(String tagName, IDictionary attribs, Boolean fAllowHtmlTags) at System.Web.UI.RootBuilder.GetChildControlType(String tagName, IDictionary attribs) at System.Web.UI.ControlBuilder.CreateChildBuilder(String filter, String tagName, IDictionary attribs, TemplateParser parser, ControlBuilder parentBuilder, String id, Int32 line, VirtualPath virtualPath, Type& childType, Boolean defaultProperty) at System.Web.UI.TemplateParser.ProcessBeginTag(Match match, String inputText) at System.Web.UI.TemplateParser.ParseStringInternal(String text, Encoding fileEncoding)
Both the Telerik.Web.UI and the Telerik.Web.Design have the version: 2011.1.413.35 and Runtime Version: v2.0.50727.
The real upshot of this is, even if I delete the ImageEditor.ascx file the error remains, which means that I'm unable to use the ExternalDialogs because by using it, the error occurs.
FYI, the RadEditor is created as a user control so it is not declared on any aspx page.
