JQuery Checking Of Values

[Brian Mains]

Hello,

Often I have a form that has these values:

RadTextBox
RadNumericTextBox
RadDatePicker
RadComboBox
RadMaskedTextBox

I often use a CustomValidator control to validate the form to ensure at least one value has been provided in the form.  Rather than write code to check each an every control to see if it has a value, is there one JQuery condition I can write to check to see if any of the controls have a value?  I tried using a CSS class to identify each control, and then target that control by doing something like:

$("#wrapper").find(".TelerikControl[value != null && value != '']").length > 0

To determine if there is any value present, but this doesn't quite work.  Can anyone share if they did this and how?

Thanks.

Hello Brian,

Our controls are ASP.NET AJAX ones and you should use the client-side API. For example if you want to get RadTextBox's value, you need to get a reference to it by using $find(<RadTextBox's ClientID>) and then call its get_value() method.

Kind regards,

Hello,

Yes, but if I have a small subset of controls within a tab, and I want to check if any of those are empty, I have to write code to check each and every control... which is a pain to write.  It would be nice if there was a global way to check this so I don't have to constantly write:

if (!!$find("<%= txtName.ClientID %>").get_value() || ..)

I can't use your global radcontrols collection either because I need to check a subset of the controls here.

Hello Brian,

Currently there is no possibility to access all RadControls on the page and apply some method to all of them. Each particular control in our suit is specific and provides different methods and properties on the client, so the same method for particular action could not be applied to all of them.
I would suggest you in your case in order to validate each control on the page, to validate the whole Page itself. You could call Page_ClientValidate() function and check to see if the validations(Custom, RequireField) are complete in the page.


All the best,
