Run existing TapGestureRecognizer from code behind

Question

Hi,

I have the following Label in Xamarin. app

<Label x:Name="LabelBack" Text="Back" Grid.Column="1" TextColor="Blue" Padding="5" HorizontalOptions="Center" VerticalOptions="Center">
<Label.GestureRecognizers>
    <TapGestureRecognizer Tapped="TapGestureRecognizerBack_Tapped" />
</Label.GestureRecognizers>
</Label>

and in my codebehind I want to invoke the TapGestureRecognizerBack_Tapped from another button.

I tried:

TapGestureRecognizerBack_Tapped(null, null);

but did not work

Kindly help.

Thanks,
Jassim

Hello,​

Welcome to our Microsoft Q&A platform!

You can move code from TapGestureRecognizerBack_Tapped to new method like following code. Then your Tapped event for label could invoke it, your button click could invoke it as well.

   private void TapGestureRecognizerBack_Tapped(object sender, EventArgs e)  
           {  
               DoSomething();  
           }  
     
           private void DoSomething()  
           {  
               //Move your tap Gesture code here.  
               Console.WriteLine("Tapped");  
           }  
           private void Button_Clicked(object sender, EventArgs e)  
           {  
               DoSomething();  
           }
