Disable client validation while clicking certain buttons in a form in mvc 2

Question

i am having an mvc 2 application in which i have a form that contains two buttons

 <% Html.EnableClientValidation(); %>
<%using(Html.BeginForm()){ %>
            <%= Html.LabelFor(m=> m.FormName) %>
            <%= Html.TextBoxFor(m=> m.FormName) %>
            <%: Html.ValidationMessageFor(m => m.FormName) %>
   <input type="submit" name="BtnSegment" value="Add" class="button_99" title="Add" />
    <input type="submit" name="BtnSave" value="Save" class="button_99"  title="Save" />
<%} %>

Now my requirement is to disable validation when the user clicks Add button. But validate when the user clicks Save Button. thanks, suraj

If you are using MSAjax for client side validation you could do this:

<input type="submit" name="BtnSegment" disableValidation="true" value="Add" class="button_99" title="Add" />

Notice the disableValidation attribute on the button. Obviously that's invalid HTML Transitional and you could cheat by appending this attribute using javascript:

document.getElementById('idOfYourButton').disableValidation = true;

Still stinky but at least the validator will be happy.

Personally I consider MSAjax library a crap. With the jquery.validate plugin (which by the way is the default client side validation mechanism in ASP.NET MVC 3) you simlpy apply the cancel class to the button:

<input type="submit" name="BtnSegment" value="Add" class="button_99 cancel" title="Add" />
