設置一個按鈕的背景並不像android的dev.it更簡單;WP7改變一個按鈕圖像的代碼與一個url
中的.xaml文件:
<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>
在此
cs文件:
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"
我怎麼能得到這個形象Button.If不了什麼設置按鈕背景的方法與代碼中的網址;
謝謝,通過這種方式,我可以設置一個帶有url的ImageSource。但對我來說很重要。總之,我怎樣才能獲得一個Button中的Image控件; – 2012-03-05 10:52:12
最後我發現[它](http://stackoverflow.com/questions/9444091/how-to-reference-image-in-controltemplate「感謝這個人」),它運作良好。 – 2012-03-05 11:13:09
