[Solved] Editor inside window using LoadContentFrom with validation

[ctaleck]

I am trying to get a Telerik HTML Editor to work inside a Telerik Window using the LoadContentFrom method. I also want the Data Validation to work on the Editor. I am unable to do this. The uploaded project shows a working sample first (IndexOrig using the Content method) and then the non-working sample (Index using LoadContentFrom).

Run the project and see:
1. Click on the Submit button with no input and the validation works
2. Close the window
3. Click on the "Home" link to open a page using the LoadContentFrom method
4. It crashes.

Any ideas on why this would be a problem?

Hi Ctaleck,

1. You are including the MicrosoftMvc*.js files twice (in each master page) and are getting an error. Removing one of the declarations resolves that.
2. The CommentForm.aspx is rendering a form that posts to the CommentForm page, which is a partial (and when it gets rendered, it shows without the Site.Master around it -- thus, with no style)
3. In order to enable the client-side validation after loading AJAX content, you have to call
   Sys.Mvc.FormContext._Application_Load();
   This can be done in the editor load event, like so:
               .ClientEvents(events => events
                   .OnLoad("Sys.Mvc.FormContext._Application_Load()")
               )

You can find the fixed sample solution attached (with an updated build that addresses an editor initialization problem).
