No Property of name Image found for Button on Windows Phone

Question

I'm getting an issue I don't understand. I have a Button with an image defined with the following code :

<Button Image="SearchFilterIcon.png"
              Grid.Row="0"
              Grid.Column="1"
              Clicked="OnButtonFilterClicked" />

This works well on Android. The image is displayed on my button but when I launch the Windows Phone application, I get a XamlParseException which says that : No Property of name Image found.

How is it possible? The Button widget isn't the same on Android and Windows Phone?

Answer 1

If you do the following:-

Button objButton1 = new Button();
objButton1.Image = (FileImageSource)ImageSource.FromFile("testImage1.png");
objStackLayout.Children.Add(objButton1);
this.Content = objStackLayout;

Then it will work (via code-behind).

The Button control always had the Image property, even in Xamarin.Forms v1.2.2x, so this is not a new property introduced and nothing to do with having the latest packages installed.

As a workaround perhaps you should consider giving the XAML Button a x:Name as in:-

<Button x:Name="myButton1"/>

And then assign the image from code-behind:-

myButton1.Image = (FileImageSource)ImageSource.FromFile("testImage1.png");

Update 1

This was a case of very old libraries being used (v1.0.6186). Once the project is reupdated to the latest binaries for v1.2.3x, then this works fine.
