In an MVC3 application I have a view rendering two Ajax partial views: a Create partial view and a List one. In the Create partial view I try to fire client validation on OnBegin event, but this does not happen.
The error messages I get, when I force errors, are the one indicated in the model annotations, and not the ones I define in the validation function called OnBegin (e.g.:
-
leaving the event place empty, I get “The event place is required” (annotation) instead of “Where did it take place?” (FieldsValidation function),
-
for the event description I get “The event description is required” (annotation) instead of “Tell us sth about it!” (FieldsValidation function)
-
and the validation summary message sais “Error on creation. Please retry after corrections.” instead of “Save failed. Please correct errors and retry.“(FieldsValidation function)).
I tried to put a breakpoint in the FieldsValidation function, but it was never reached.
Just to make sure, I also tried to call OnBegin a function displaying an alert (after the test I restored the original call to FieldsValidation function):
function toDoOnBegin() { alert("This is onBegin"); }
The alert never displays!
If all fields are properly filled in, the event is correctly created and displayed in the event list (the other partial view). The problem is uniquely the function call OnBegin.
Please explain me what did I do wrong, did I miss to include something or what else is it?
Thank you truly.
