if (errorArgs.lineNumber != 0) { errorMsg += "Line: " + errorArgs.lineNumber + "\n"; errorMsg += "Position: " + errorArgs.charPosition + "\n"; } errorMsg += "MethodName: " + errorArgs.methodName + "\n"; break; case "ParserError": errorMsg += "Xaml File: errorMsg += "Xml Element: errorMsg += "Xml Attribute: errorMsg += "Line: errorMsg += "Position: break; default: break; } alert(errorMsg); } " + errorArgs.xamlFile " + errorArgs.xmlElement " + errorArgs.lineNumber + "\n"; + "\n"; + "\n";
" + errorArgs.xmlAttribute + "\n"; " + errorArgs.charPosition + "\n";
12.把 xaml 段内置在 aspx 或 html 页面中
这样的话就不用单独的 *.xaml 文件来承载 SilverLight 对象控件元素内容.
I. 页面代码(Default.aspx)
II.Xaml 文件代码 文件省略, 其内容集成到 Default.aspx 页面中了. III.页面对应的 JS 文件代码(Default.aspx.js)
function createSilverlight() { Silverlight.createObjectEx({ source: '#xamlContent', parentElement: document.getElementById("SilverlightControlHost"), id: "SilverlightControl", properties: { width: "350", height: "350", version: "1.0", background: "white", isWindowless: "true", enableHtmlAccess: "true" }, events: {} }); } function setDate(sender, eventArgs) {
sender.text = Date(); }
2).制作图形示例 13.基本图形形状示例 I. 页面代码(Default.aspx)
II.Xaml 文件代码
<Canvas Name="parentCanvas" xmlns="/client/2007" xmlns:x="/winfx/2006/xaml" Loaded="onLoaded" >
X2="50" Y2="50" Stroke="Black" StrokeThickness="4" />
<RadialGradientBrush GradientOrigin="0.5,0.5" Center="0.5,0.5" RadiusX="0.5" RadiusY="0.5"> <RadialGradientBrush.GradientStops> <GradientStop Color="Red" Offset="0" /> <GradientStop Color="Blue" Offset="0.25" /> </RadialGradientBrush.GradientStops> </RadialGradientBrush>
<Ellipse Fill="Yellow" Height="100" Width="200" StrokeThickness="2" Stroke="Black" Canvas.Top="100"/>
<RotateTransform CenterX="0" CenterY="0" Angle="45" /> </Canvas>
III.页面对应的 JS 文件代码(Default.aspx.js)
function createSilverlight() { Silverlight.createObjectEx({ source: "Page.xaml", parentElement: document.getElementById("SilverlightControlHost"), id: "SilverlightControl", properties: { width: "350", height: "350", version: "1.0", background: "white", isWindowless: "true", enableHtmlAccess: "true" }, events: {} }); } function onLoaded(sender, eventArgs) { }
14.画刷对象的使用 I. 页面代码(Default.aspx)
II.Xaml 文件代码
<Canvas Name="parentCanvas" xmlns="/client/2007" xmlns:x="/winfx/2006/xaml" Loaded="onLoaded" > <Rectangle Width="100" Height="100" Fill="Red" /> <Rectangle Width="100" Height="100" Fill="#FFFF0000" Canvas.Top="110" /> <Rectangle Width="100" Height="100&q
uot; Canvas.Top="220" > <Rectangle.Fill> </Rectangle.Fill> </Rectangle> <Rectangle Width="100" Heig
