server side validation example

[Paul]

I'm trying to find an example of using server-side validation with scheduler.

All I can find is examples on using it with the grid, but the set up is very different so it's unclear how to adapt it.

In particular, the validation on grid examples I've found all do things like this:

function showMessage(container, name, errors) {
        //add the validation message to the form
        container.find("[data-valmsg-for=" + name + "],[data-val-msg-for=" + name + "]")
        .replaceWith(validationMessageTmpl({ field: name, message: errors[0] }))
    }

Yet there is no field with attribute 'data-valmsg-for' by default, so this will not work unless I manually insert one, yet there is no example of how this should be laid out.

When using client side validation, an error field is automatically added which looks like this:

<div class="k-widget k-tooltip k-tooltip-validation k-invalid-msg" style="margin: 0.5em; display: block;" data-for="last_name" role="alert"><span class="k-icon k-warning"> </span>last_name is required<div class="k-callout k-callout-n"></div>

But again this doesn't exist pre-error.

How can I hook these two things together?

Cheers, Paul.

Hello Paul,

I would suggest you use the Model field validation option to define your custom validation rule. Inspired by this blog post, I created a simple Dojo demo, which demonstrates how to implement remote validation in Scheduler. Check it and me know if I can be of any further assistance.
