向silverlight传递自定义参数
在silverlight往往还是有一些获取不到的东西,比如说客户机的ip等的数据.可以通过初始化sl时把参数传入sl中.
1.修改page类
public Page(string passText)
{
InitializeComponent();
txtPass.Text = passText;
}2.修改App.xaml.cs
private void Application_Startup(object sender, StartupEventArgs e)
{
// Load the main control
string passText = e.InitParams["passText"];
this.RootVisual = new Page(passText);
}3.传递参数
- 方法1: Code
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls"
TagPrefix="asp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>passtxt</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div style="height: 100%;">
<asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/HowTo.xap" Version="2.0"
Width="100%" Height="100%"/>
</div>
</div>
</form>
</body>
</html>
protected void Page_Load(object sender, EventArgs e)
{
Xaml1.InitParameters = "passText=参数_方法1";
}
- 方法2:
<object data="data:application/x-silverlight," type="application/x-silverlight-2-b1" InitParameters="passText=123" width="100%" height="100%">
<param name="InitParams" value="passText=参数_方法2" />
<param name="source" value="ClientBin/HowTo.xap"/>
<param name="onerror" value="onSilverlightError" />
<param name="background" value="white" />
<a href="http://go.microsoft.com/fwlink/?LinkID=108182" style="text-decoration: none;">
<img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
</a>
</object>
传递多个参数也是一样的.定义的时候改一下.后边的方法也类似.
public Page(string passText1,string passText2)
{
InitializeComponent();
txtPass1.Text = passText1;
txtPass2.Text = passText2;
}参数间用","隔开
<param name="InitParams" value="passText1=参数1,passText2=参数2" />ok 获取参数完成 ;)
