[wpf] c# 코드로 Button Background 변경

 

xaml에서가 아닌 c# 코드를 통해서 Button Background의 Image Source를 변경하는 방법입니다.

 

xaml

<Grid>     <Button Name="Btn1>         <Button.Background>             <ImageBrush ImageSource="pack://application:,,,/camera.png"/>         </Button.Background>     </Button> </Grid>

c#

private bool b = false; private void Button_Click(object sender, RoutedEventArgs e){     Button btn = sender as Button;     if(btn == Btn1){         if(b){             Btn1.Background = new ImageBrush(new BitmapImage(new Uri("pack://application:,,,/camera.png")));             b = false;         }else{             Btn1.Background = new ImageBrush(new BitmapImage(new Uri("pack://application:,,,/letter.png")));             b = true;         }     } }
