Hide button after it was clicked

Issue

I would like to hide a button after it was clicked but I don't know how.

C#

private async void btn1Clicked(object sender, EventArgs e)
{
    if (condition)
    {
        // hide button
    }
}

XAML

<Button Clicked="btn1Clicked"/>

Solution

You can do the following

private async void btn1Clicked(object sender, EventArgs e)
{
    Button btn = (Button)sender;

    if(condition)
    {
        // hide the button
        btn.IsVisible = false;
        
        // or disable the button. 
        // As Caius Jard said, disappearing buttons sometimes cause confusion.
        btn.IsEnabled = false; 
    }   
}
