Reset default values - unfilter action

Hi all,

How can I reset  input UI elements( Input Text or Drop Down) to the default values ?

I have a form that contains Drop Down, Date Picker etc.

This form used as a filter for some dashboard.

It contains 'filter' and 'unfilter' buttons.

The question is how can I put the default values to the form UI elements while clicking the 'unfilter' button.

Please note that unfilter action is working ( I pass default values to BAPI) but UI elements doesn't initilized to the default values.

Thanks,

Ola
