Getting a 'RadImageEditor' is not a known element error.

[Cameron]

Hi,

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'.

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.
 
Suggestions?

Thanks,
Cameron

Hello Cameron,

RadImageEditor was introduced in Q2 2011 (version 2011.2.712) which means that you use dialogs folder taken from a newer installation with older Telerik.Web.UI assembly. Please, upgrade the Telerik.Web.UI.dll in the bin folder to fix the problem.

Best wishes,

Thanks Rumen, that answers that question.

Now here's a new one:
If I'm modifying only the TableProperties.ascx, TableProperties.Border, and TableWizard.ascx and only have those files in the project, I still get the error regarding the RadImageEditor, even though I'm not referencing it anywhere.

Does this mean I have to abandon using the external dialogs?

Thanks,
Cameron

Hello Cameron,

If you do not like to upgrade to the latest version, my recommendation is to download version 2011.1.413.35 and copy the TableProperties.ascx, TableProperties.Border, and TableWizard.ascx from its EditorDialogs folder. They should be taken from the same installation from which is taken the Telerik.Web.UI.dll.

If you still experience any issues, please open a support ticket and send a sample working project which demonstrates them. I will examine the files and do my best to provide a solution.
