win universal app - C#: PointerPressed has been called twice when I click the image -


i beginner in uwp. wanna add click event image change splitview's open-status. have image in ma xaml: 

<image x:name="image_1_6" horizontalalignment="left" height="200" margin="1225,559,-171,0" verticalalignment="top" width="200" source="assets\images.jpg" pointerpressed="image_1_6_pointerpressed"/>

i define image_1_6_pointerpressed this:

private void image_1_6_pointerpressed(object sender, windows.ui.xaml.input.pointerroutedeventargs e)     {         mysplitview.ispaneopen = !mysplitview.ispaneopen;     }

but when click on image mysplitview open , close! can body me on please? thanks.

pointerpresseddoesn't working click event. calls when pressed , keep button , when leave button event finishes. when click on image think event calls twice! should call tapped event this.

<image x:name="image_1_6" horizontalalignment="left" height="200" margin="1225,559,-171,0" verticalalignment="top" width="200" source="assets\images.jpg" tapped="image_1_6_pointerpressed"/>
