You can do this in several ways:
First:
Use canvas

Second:
Use some js library like:

Third:
Use html5 FormData

I'm creating a site where I don't want anything to be done via custom javascript/jquery code at all, and I'm not sure it's going to be possible so need some advice.
The things that I want to be able to do are:
Load a JQuery (or Jquery style) dialog box containing a partial view.
Have a button that will select the "SelectedValue" from a dropdown list and render a partial view. (e.g. select a user from a dropdown and then click a button to add them to a list)
Append a partial view to an existing div.
I'm sure that all the above can be done using custom javascript, but what I want to is to use the standard Ajax and Html helpers that come with MVC3.
Main reason is that I've been struggling to get to grips with jQuery, but I also thought it would be nice to see if it can all be done without having to add a new script to the site.
As always, any help is greatly appreciated (even if it's just pointing me to articles).
The standard Ajax and Html helpers that come with MVC3 are for handling server-side stuff. Even the #Html.ValidationMessageFor helper usually uses their unobtrusive validation lib for jQuery validate.
Keep trying at jQuery, you'll get it. There is a reason it is so popular!
Update
I believe you can do #3 using #Ajax.ActionLink, but don't think you can do 1 or 2 out of the box with the Ajax html helper.
It seems that you can use the Ajax.BeginForm method to do this.
There are issues with the fact that it has been in a separate form as I can't nest the forms though.
I have a working django form that submits and the django view handles the form data and stores the data in the database. I would like to change this submission to use AJAX so that it validates one of the fields of the form with the database. There are no good examples out there for AJAX django. The ones that are out there, I have tried and just don't work. I used this example with prototype https://code.djangoproject.com/wiki/AjaxPrototypeNewForms but this doesn't post form values and the django is not able to get any form values.
A solid working example would be great.
Please Help!!!
I wrote a couple of form classes, one for regular forms, one for model forms, that return any errors as json. I have a working example of how to use the form, and also how to process the json response back to your page using jQuery. The code is available at: http://djangosnippets.org/snippets/2393/
Hope that helps you out.
For 90% of my site the standard MVC annotation with client script method is working a treat. But I have a form on the site that is quite complicated with multiple instances of dynamic form content dependant on answers to questions etc.
If I have the unobtrusive script included on the page, it's capturing the form submit and not allowing my custom jquery validate to validate the form.
I don't really want to refactor the site to have a seperate layout to remove the script when it's not needed. I wondered if there was an easy way to give control back to my custom validate script.
Any help would be great.
In your view you can disable client side validation like this
Html.ViewContext.ClientValidationEnabled = false
