Select All in webdropdown
posted

Hello,

I have a problem with the multiselect on a webdropdown: I added a script that allows me to select/uselect all items in the dropdown.

function selectedIndexChanged(sender, eventArgs) {

        var activeIndex = sender.get_activeItemIndex();

        var items = sender.get_items();

 

        if (activeIndex == 0 && items.getItem(0).get_selected() == true) {

            for (i = 1; i < items.getLength(); i++) {

                var item = items.getItem(i);

                item.select();

            }           

        }

        else if (activeIndex == 0 && items.getItem(0).get_selected() == false) {

            for (i = 1; i < items.getLength(); i++) {

                var item = items.getItem(i);

                item.unselect();

            }

        }

        else if (activeIndex != 0) {

            if (items.getItem(activeIndex).get_selected() == false) {

                items.getItem(0).unselect();

            }

        }

    }

My problem is that when I select 'All', the 'All' string appears in the text of the dropdown along with all the other selected elements.

I would like to set the text to "All" without having the full list of elements.

Any idea?

Thank you in advance.

    Hi,

    Just to be sure I understand you right, you want after selecting "All", the text of the WebDropDown to be "All". As now I see it's "All, Active, WithDrawn" ?

    Is that correct?

    Thanks,
