Added new function to update selected items if the source Select is changed about dropdown-check-list HOT 11 CLOSED

How does one call this function from the aspx page ?

Is it something like

$('mydropdown').updateSelection() ;

to call this use:

$('#mydropdownID').dropdownchecklist("updateSelection");

Thanks. Do you have a function for unchecking all the items ? or possibly point 
me in
the right direction ?

@victorbh: have a look at _syncSelected function for some clues.
Something like below will do it (if you don't need to keep track of the 
firstItemChecksAll option):

 selectAll: function() {
            var allCheckboxes = this.dropWrapper.find("input");
            allCheckboxes.attr("checked", true);

            // do the actual synch with the source select
            var selectOptions = sourceSelect.get(0).options;
            allCheckboxes.each(function(index) {
                $(selectOptions[index]).attr("selected", true);
            });

            // update the text shown in the control
            self._updateControlText();
        }, 

and then call with $("#s1").dropdownchecklist("selectAll")

Sorry about this novice question, but I can't see the "updateSelection" function
defined in the latest release - 0.9. Has it been done as a different function 
name?

As of version 0.9 the function is not needed because ddcl automatically 
synchronizes 
with values changes in the source select. What are you trying to do?

We've got a separate (non-jQuery, legacy) script that does a select all/none on 
the
input. Perhaps the way this script works, but when it runs I can see the hidden
select is being updated (as it would if DDCL was not applied) but the dropdown 
widget
didn't seem to automatically synch. That would be awesome if it did - is that 
the
expected behaviour? 

If I add in the updateSelection function and then call this explicitly after the
select all/none script it seems to work perfectly - ie takes the selects from 
the
hidden select. 

I'm attaching a test case if it helps (drop this in the ddcl/src folder). The 
first
select all/none shows the auto-synch isn't happening. 

saw the comment on the demo page - update from selection can be achieved with a
destroy and recreate, ie no need for "updateSelection" function:
$("#select").dropdownchecklist("destroy");
$("#select").dropdownchecklist();

thanks, great work

If you're programmatically changing the value of the source select, you'll need 
to 
trigger a change event on the select to get ddcl to recognize the change.

Example:
$("#sourceSelect option").attr("selected","selected");
$("#sourceSelect").trigger('change');

If you're not using jQuery you'll need to find another way to trigger the 
change...
