Is there a dataSource function I can call to trigger a read(), but only if necessary?

[iCognition]

Hello we have a number of input elements, dropdowns, multiselects, etc which we are trying to defer loading for.

The problem is they use custom shared datasources, so setting them to AutoBind false is not automatically triggering the read() function, and we have added some additional dataSource behavior around multiselectors, which leads me to my question:

Is there a dataSource function like read() which only reads data from the server if its actually necessary? e.g. on the first load, if the dataSource has detected that the user has done something to the UI element to warrant a refresh, etc?

I know there are a tonne of undocumented functions on the kendo objects, some of them not intended for everyday use, but I'd be interested to know if any of them do what we need.

Hi Matt,

These inputs - the MultiSelect and DropDownList - do not have saving to the remote serve functions. Generally, they serve as options for the user to update other UI parts of the application.

Are these inputs inside a form?

Can you share a more specific scenario so I can better understand the case?

Regards,

Nikolay
