Remarks

ImageLoader is an innovative control that supports loading for embedded, internal and external image. The ImageLoader provides built-in features to show the image loading progress, which can be optionally disabled or further customized through property sets.

By default, ImageLoader automatically loads the image specified in ImageSource property when the page is loaded. If you do not want to load the image directly, you can set the AutoLoad property to False. You can programmatically load the image in code by using LoadImage() API.

The following examples show how to use the ImageLoader control using XAML and code.

XAML Copy Code 
<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
    <Intersoft:ImageLoader x:Name="Logo" Width="260" Height="61" ImageSource="http://www.intersoftpt.com/WebResources/Images/IntersoftSolutions_logo.png" AutoLoad="False"></Intersoft:ImageLoader>
    <Button Click="Button_Click" Content="Load Image" HorizontalAlignment="Center"></Button>
</StackPanel>
C# Copy Code 
private void Button_Click(object sender, RoutedEventArgs e)
{
    this.Logo.LoadImage();
}
