Autosize Button with an image

How to make a buttons auto-size with an image instead of fixing a default button size? Thanks really appreciated.

All my buttons are fixed size, I need to have some buttons buttons to be big, some small depending on the image size.

heres my codes:

 Button tba = new Button();
            tba.FontSize = 19;
            tba.Height = 300
            tba.MinWidth = 100;
           //tba.Height = Double.NaN;
           //tba.Width = Double.NaN;
            ImageBrush brush = new ImageBrush();
            BitmapImage bitmap = new BitmapImage();

            bitmap.BeginInit();
            bitmap.UriSource = new Uri(@"files.png" + lstQuestion[i].ImageURL.Substring(1), UriKind.Absolute);
            bitmap.EndInit();
            brush.ImageSource = bitmap;
            tba.Background = brush;
            wrapPanel1.Children.Add(tba);

To size the button to the image: host the image in an Image and set Image.Strech to None and remove the sizes from your Button:

Button tba = new Button();
Image myImage = new Image();
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.UriSource = new Uri(@"files.png" + lstQuestion[i].ImageURL.Substring(1), UriKind.Absolute);
bitmap.EndInit();
myImage.Source = myBitmapImage;
myImage.Stretch = Stretch.None;
tba.Content = myImage;

If you want more than just an image in your Button add the image to panel that will let the image fill the space, e.g. a Grid, then set Button.Content to that panel.

Incidentally in XAML you can just go:

<Button>
    <Image Strech="None" Source=".\Water Lilies.jpg"/>
</Button>
