Select multiple list items (programatically from the controller)

[bothwell]

Probably a question with a really simple answer but I haven't been able to find an answer searching.

I have a list with some data in it, depending on a setting, some of the list items are to be pre-selected on load. The list has been configured with mode: "multi" and multiple selection works correctly on tap.

To pre-select list items, I am using this in my controller:

                            Ext.each(myData, function(category, index){
                                if(category.ismember == 1){
                                    myList.select(index);
                                }
                            });

This does select items, but it resets the selection on each pass, so only the last index ends up highlighted.

I've also tried passing in a comma separated list of indexes:

                               myList.select(1, 2);

... but that will only select the first index given.

Is there a way to achieve multiple selections from the controller?

Hi bothwell,

from the docs (http://docs.sencha.com/touch/2-1/#!/...-method-select):

keepExisting : Boolean
If true, the existing selection will be added to (if not, the old selection is replaced).

So I think you have to set the 2nd parameter to true:

Ext.each(myData, function(category, index){
    if(category.ismember == 1){
        myList.select(index, true);
    }
});

I didn't test it, but it sounds plausible

Best regards,

That is exactly right!

Some day soon I swear I'll get the hang of finding the right place to look in the docs

Thank you!
