MVC2 Client-Side Validation for injected Ajax content

Question

I am making an Ajax call and adding content to a form inside a MVC2 app. I need to update the Client Validation Metadata with the validation for my new content. ``` ``` Is there a way to generate this metadata for a partial view ? Thanks in advance.

Accepted Answer

Finally got it to work.

The answer is simple: don't waist time with MicrosoftMvcValidation.js. It is generated with Script# which makes it difficult to extend.

Switch to xVal and jQuery Validation. It doesn't need a form to generate the client validation metadata. Also in order to load validation for a AJAX request all you have to do is to call the following after you have the new Html:

```
lForm.find("#placeholder").empty();                     
lForm.valid();
lForm.find("#placeholder").html(responseHtml);   
```

That does it. First you remove the old content. Than re-run validation to get rid of potentially obsolete validation errors. Than add the new content. Works like a cham.

Also jQuery Validation makes it really easy to enable or disable validation for a certain field (conditional validation).
