Question

I have a button called “Verify”. When clicked it should change its content to “Verifying…” and once processing is completed it should show “Verified”. How should we achieve this? I am new to wpf. Any help will be appreciated.

private void btnVerify_Click(object sender, RoutedEventArgs e)  
{  
    btnVerify.Content = new BitmapImage(new Uri("Verifying.png", UriKind.Relative));
    VerifyData(); // this takes almost few seconds to few minutes 
    btnVerify.Content = new BitmapImage(new Uri("Verified.png", UriKind.Relative)); 
}

because you’re new to WPF, i’m assuming you’re NOT using MVVM. in that case:

hook onto the Click event and in the method:

OnVerifyClick(object sender, RoutedEventArgs e)
{
    Button verifyButton = sender as Button;
    if(verifyButton == null) { return; }

    verifyButton.Content = "Verifying...";
    DoProcessing();
    verifyButton.Content = "Verified";    
}
