Hi Stuart Hemming,
Please accept my apologies for the late reply.
Is your FormCreating event ajaxified with RadAjaxManager? The ReponseScripts will only work after an ajax event, so make sure that your event is ajaxified:
Also in External Edit in RadDock
function is written in camel-case (e.g. the first letter is small). In your code you are trying to call the function written in Pascal-case:
RadAjaxManager LocalManager = RadAjaxManager.GetCurrent(Page);
This is causing an error because no such function can be found. Just replace the name of the function to start with small letter and everything will be set.
All the best,
the Telerik team
