Kendo button calling a javascript function on click

I have a HTML input like this:

<input type="submit" name="saveForm" value="Save" onclick="return validateForm()"/>

here's the validateForm function called when the button is clicked:

function validateForm() {
    if (someErrorCondition) {
        alert("error");
        return false;
    }
    reallySubmitForm();
}

I want to replace this button with a Kendo Button, and I'm doing like this:

@(Html.Kendo().Button()
    .Name("save")
    .HtmlAttributes( new {type = "submit"})
    .ImageUrl(Url.Content("~/Images/save.png"))
    .Events(e => e.Click("return validateForm"))    <---------  here's the problem
    .Content("Save")
)

The problem is that, if I have

.Events(e => e.Click("return validateForm"))

the button isn't rendered correctly: the "return" word is messing it up. If I have this

.Events(e => e.Click("validateForm"))

it's rendered correctly and the function is called. However, when clicked, the button submits the form anyway, without caring with validation.

How can I achieve the former behaviour with this Kendo Button?

Try Following code:

@(Html.Kendo().Button()
.Name("save")
.HtmlAttributes( new {type = "submit"})
.ImageUrl(Url.Content("~/Images/save.png"))
.Events(e => e.Click("validateForm"))
.Content("Save"))

function validateForm(e) {
  if (someErrorCondition) {
    alert("error");
    e.preventDefault();
  }
 else {
      reallySubmitForm();
    }
}

I have tried with only "return" and it works. But using e.preventDefault() does not do the trick for me.

Try to use e.preventDefault() instead of returning false in order to stop the submit event. That's the recommended way anyway. :)
