c# - How use ContextFlyout in a StackPanel in UWP? -

-

in gridview, trying show context menu when user right clicks item.

i tried:

 <gridview.itemtemplate>     <datatemplate>        <stackpanel orientation="vertical" width="120" background="lightblue">        <stackpanel.contextflyout>              <menuflyout>                   <menuflyoutitem text="change color" click="changecoloritem_click" />              </menuflyout> ...

but stackpanel.contextflyout throws error. missing?

update

the error is: the attachable property 'contextflyout' not found in type 'stackpanel'

contextflyout property of uielement, , stackpanel derived uielement.

contextflyout property of uielement, , stackpanel derived uielement.

yes right, careful contextflyout property available since introduced version 3.0, version 10.0.14393.0. need check api contract version , device family version.

for api contract version 1.0/2.0, @igor damiani suggested, can use flyoutbase.attachedflyout, , can datacontext example in righttapped event of stackpanel:

private void stackpanel_righttapped(object sender, righttappedroutedeventargs e) {     flyoutbase.showattachedflyout(sender stackpanel);     var datacontext = ((frameworkelement)e.originalsource).datacontext; }

but noticed menuflyoutitem possible color changing, need access uielements inside stackpanel or stackpanel itself. if so, it's better bind color property implemented inotifypropertychanged interface.
