error: bindingexpression path error: 'latitude' property not found on 'mappin, version=1.0.0.0, culture=neutral, publickeytoken=null'. bindingexpression: path='latitude' dataitem='mappin, version=1.0.0.0, culture=neutral, publickeytoken=null'; target element 'windows.ui.xaml.controls.textblock' (name='txtlatitude'); target property 'text' (type 'string') xaml:

namespace maplocatornamespace { public sealed partial class maplocator : page { private void stckpin_tapped(object sender, tappedroutedeventargs e) { stackpanel stkpin = (stackpanel)sender; double lolatitude = convert.todouble(((textblock)stkpin.children[1]).text); } } public class doubleconverter : ivalueconverter { public object convert(object value, type targettype, object parameter, string language) { var doublenumber = (double)value; return doublenumber.tostring("0.00#################"); } public object convertback(object value, type targettype, object parameter, string language) { throw new notimplementedexception(); } } } how can bind latitude textblock , @ codebehind ?
i have solved myself,
what have done is, have add int column index may mapitem class, , added in 'tag' attribute of image. on tap event tag , index can search in list , and tapped pin.
now having pin whole detail, , current location , pin location can draw route.
thank you.
