InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
// here will shows the 'image2' and also give click event to turn 'image1'
}
}
}
Please help
I would tackle this by having a couple of images in your XAML:
<Button Click="Button_Click">
<Grid>
<Image x:Name="imageOne" Source="resourse/image1.jpg"/>
<Image x:Name="imageTwo" Source="resourse/image2.jpg"
Visibility="Collapsed"/>
</Grid>
</Button>
The use of x:Name
causes visual studio to generate a field for each image. The second image is 'collapsed', i.e. hidden.
You click handler then does the following:
private void Button_Click(object sender, RoutedEventArgs e)
{
if (imageOne.Visisbility == Visibility.Visible)
{
imageOne.Visisbility = Visibility.Collapsed
imageTwo.Visisbility = Visibility.Visible
}
else
{
imageOne.Visisbility = Visibility.Visible
imageTwo.Visisbility = Visibility.Collapsed
}
}
On each click it toggled the visibility of each image.
This is easier than changing the Source of the image, which involves URIs etc...
