How to know if a button has been clicked? Xamarin Forms

Question

I have sometimes needed to know when a button was clicked and did not find a property natively in C#/Xamarin. For example:

In this image above we have a Entry with a Text (for example only) written Pesquisa... by Defaut and with a function ToUpper (to capitalize all text), in case I click the button LIMPAR I wish I could add the text Pesquisa... again, but the function ToUpper forces the text to stay PESQUISA.... So I thought I’d make one if who did the following:

if (BotãoLimparPressionado = true)
{
   EntryPesquisar = "Pesquisa..."
}
else    //a função para os outros casos continuariam normais
{
   EntryPesquisar.ToUpper
}

Assuming you are developing the visual via XAML...

In your XAML use

<Button Clicked="OnClick">Button</Button>

And in your codebehind

private bool BotaoClicado = false;

public void OnClick(object sender, EventArgs args)
{
  BotaoClicado = true;
  // Aqui dentro você poem sua programação
}

private void OutroMetodo()
{
  if(BotaoClicado)
  {
    //Aqui você poem o que deve ser feito
  }
}
