checkbox - How to add values to resources from a list? (wpf) -

i have combobox filtering purposes , want "all" first value of it. , have added check boxes each items can select multiple items. when "all" checked want other items checked. , when unchecked other items should unchecked.

resource:

 <x:array x:key="source" type="sys:string">     <sys:string>apple</sys:string>     <sys:string>orange</sys:string>     <sys:string>grapes</sys:string> </x:array> 

combobox:

<combobox x:name="myfilter">     <combobox.itemssource>         <compositecollection>             <comboboxitem>                 <checkbox x:name="all" foreground="black">all</checkbox>             </comboboxitem>             <collectioncontainer collection="{staticresource source}"/>         </compositecollection>     </combobox.itemssource>     <combobox.itemtemplate>         <datatemplate>             <checkbox name="chkfruits" content="{binding}" foreground="black" ischecked="{binding elementname=all, path=ischecked, mode=oneway}"></checkbox>         </datatemplate>     </combobox.itemtemplate> </combobox> 

and want bind fruit list.

so questions are:

1) there way bind list collectioncontainer?

2) if can't bind property directly collectioncontainer other ways can this?

3) have tried add list values resource.

 <x:array x:key="source" type="sys:string"></x:array> 

assume fruit list

list<string> fruitlist = new list<string>() {"apple", "orange","grapes", "pineapple"}; 

i have tried didn't work.

resources.add("source", fruitlist); 

is there way add list values source?
