c# - Label TapGesture doesnt fire Xamarin Forms -

i trying add tapgesturerecognizer label.

 sliderabout.gesturerecognizers.add(new tapgesturerecognizer  {      command = new command(() => openaboutappasync()),  }); 

sliderabout label wich set in xaml , works correctly.

 <scrollview grid.row="1">                 <grid verticaloptions="start" horizontaloptions="start" margin="20,20,0,0">                     <grid.rowdefinitions>                         <rowdefinition height="60"/>                     </grid.rowdefinitions>                      <label x:name="sliderabout"                             text="Über die app"                             grid.row="2"                              textcolor="white"                             fontfamily="open sans light"                             fontsize="medium"/>                     </grid>             </scrollview> 

the code gets run ( put in class constructor)

but method doesnt fire when tap label... why wont fire?

thanks help!

you can add gesture recognizer directly xaml , action in code behind or view model if you're using mvvm approach. in case this:

<label x:name="sliderabout" text="Über die app" grid.row="2"  textcolor="white" fontfamily="open sans light" fontsize="medium">     <label.gesturerecognizers>         <tapgesturerecognizer tapped="onlabeltapped" />     </labelgesturerecognizers> </label> 

and in code behind

private void onlabeltapped (object sender, eventargs e) {     //your code here }
