[Solved] Form Validation & Other Properties Questions

[Randy]

Hi,
I started to use the html date picker (ver 2013.1.417) on our project and ran into several issues.
I think they are fatal flaws and will force us to have to use something else like the MS Win8 SDK datepicker.
It would be great if I'm wrong, so:

1. Can I have the control initialized with certain dates disabled?  In most of my scenarios, my customers can only select weekdays (and then I also have some custom weekdays that are unavailable, i.e. company holidays)

2. The biggest issue it seems is validation. This control really needs to tie into html5/windows store form validation.
I need this picker to be able to have properties such as ".required" & ".setCustomValidity".
It needs to tie into a form when I ask the submit event if "event.target.checkValidity()" is valid or not.
And it needs to tie into the built in form input styles.

#elementname input:valid {
}

#elementname input:invalid {
    border:solid red;
    font-weight:bold;
}

#elementname input:required{
}

#elementname input:optional{
}

Any thoughts or insights are appreciated.
(or send these thoughts on to the dev team for consideration for a future release.)

Thanks,
Randy

Hi Randy,

The design of the RadDatePicker control is such that it is not aware of week days and weekends. In your scenario, it may be better to use the new RadCalendar control (officially available from tomorrow, now in Beta). It allows you to select dates and to customize its behavior to ignore weekend days selection.

Since you want to validate this selection, you should better tie the RadCalendar selection to an input element, which you can easily validate.

You can find an example using such approach attached to this message. It handles the weekday selection only logic and makes sure that only dates selected in the calendar are set to the input. You can get the selected date object, using the hidden input added right before the input element. Furthermore, the calendar has some custom styles applied to the weekends, so they look disabled.

Give the example a try and let us know if there is anything unclear about the implementation.

Also, note that this is just a sample implementation, you can change the approach or customize the logic to better fit your scenario.
