I'd like to use a javascript call to reset a double-list control when I click on a button.

I tried IbComposer_ResetDownChainControls, but that doesn't work, as it's not a chained control. I'd rather not have to make the double-list control chained to a dummy parent.

Thanks,

Since this doesn't work:

IbComposer_ResetDownChainControls('customselect7' );

I tried this, which appears to reset the double-list - setting the control to any non-existent value will do the job:

IbComposer_setCurrentSelection('customselect7' ,'x');

The one thing I don't like is that the previously selected values are put at the bottom, which means I would need to use javaScript or jQuery to sort the selectfrom list box.

Did you find anything out about sorting the values correctly from the selectfrom?

Matt, unfortunately not.

In a previous project, onInitialUpdate I used jQuery to save the selectfrom listbox in a hidden listbox and the reset list box button would copy that hidden listbox back to selectfrom. A little convoluted but it worked and you don't really need to use jQuery...

HI,
I tried the method below.
But it pushes 'empty string' to the right box of the double list.
Is there a way around it?


var arr=[];
arr.push('');
IbComposer_setCurrentSelection('customselect1', arr, false);

BM, I believe I was in v7.7.03 when I posted my workaround. Sadly, often these workarounds don't work in the next release.

I would think that just the below should work to reset the selection:

IbComposer_setCurrentSelection('customselect1', [], false);

Are you sure the unique id of that field is indeed 'customselect1'? Are you seeing any javascript errors in the console (F12)?

Hi,
here is the solution.
document.getElementById('customselect1_selectto').options.length = 0;


Thanks
