vs2010+silverlight4 error

在用vs2010作silverlight4 的时候，查看设计页面出现下面问题，不知各位大仙怎么解决此问题的，谢谢。

[HtmlPage_NotEnabled]
Arguments:
Debugging resource strings are unavailable. Often the key and arguments provide sufficient @R_445_4045@ion to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=8.0.50401.0&File=System.Windows.Browser.dll&Key=HtmlPage_NotEnabled
   at System.Windows.browser.HtmlPage.VerifyThreadAndEnabled()
   at System.Windows.browser.HtmlPage.get_Document()

 

如图所示 ：

 

google之后，才知道出错原因是用了htmlPage这个类，然后就发现了另一个小编System.ComponentModel.DesignerProperties，试试管用，好了还是赶紧分享给大家的好：

 

 

private void UserControl_Loaded(object sender,RoutedEventArgs e)

{

    // Did the QueryString contain an Email address?

    if (HtmlPage.Document.QueryString.Keys.Contains("Email") )//此外为出错的地方

        txtEmailTo.Text = HtmlPage.Document.QueryString["Email"].ToString();

}

 

Luckily,there is a special class,System.ComponentModel.DesignerProperties,which allows us to check at runtime whether we are in Design Mode or not. We can just add a check on this,and if we are in Design Mode,we get out of the Loaded event handler:

 

private void UserControl_Loaded(object sender,RoutedEventArgs e)

{

    if (DesignerProperties.GetIsInDesignMode(this))// 在出错前加上这句判断和return语句，就ok 了

        return;

 

    // Did the QueryString contain an Email address?

    if (HtmlPage.Document.QueryString.Keys.Contains("Email") )

        txtEmailTo.Text = HtmlPage.Document.QueryString["Email"].ToString();

}
