WP7 change a button image in code with a url

Question

Set a button's background is not as simple as android's dev.it's more complex;

in .xaml file:

       <Button Click="Button_Click" x:Name="img_btn">
            <Button.Template>
                <ControlTemplate>
           <!--set button background that we can hanle click event-->
                    <Image  HorizontalAlignment="Left" Margin="0,-69,0,479" x:Name="image1" Stretch="Fill" Width="480" Source="/myNameSpace;component/home_003.jpg" />
                </ControlTemplate>
            </Button.Template>
        </Button>

in this .cs file:

                JsonObject jsonObject = (JsonObject)JsonObject.Load(e.Result);
                ads_address = jsonObject["imageurl"];//get a url from jsonobject
                ImageBrush imageBrush = new ImageBrush();
                imageBrush.ImageSource = new BitmapImage(new Uri(ads_address));//ads url likes //"http://27.98.194.93/forum/images/2009/home_004.jpg";

                this.img_btn.Background = imageBrush;//this code is not work,perhaps, I can't get what I want(Image) with code "this.img_btn.Background"

how can I get this Image in Button.If can't what's the way to set a button background with a url in code;

try this

Create image source at first and then giving that source to the image control you are using.

string imagepath = "url";

ImageSource imgsrc1 = new BitmapImage(new Uri(imagepath, UriKind.RelativeOrAbsolute)); //image can be Image/ImageBrush image.Source = imgsrc1;
