C# 将2个参数从SharePoint web部件项目传递到Silverlight应用程序中的Silverlight控件

C# 将2个参数从SharePoint web部件项目传递到Silverlight应用程序中的Silverlight控件,c#,silverlight,sharepoint-2007,silverlight-2.0,C#,Silverlight,Sharepoint 2007,Silverlight 2.0,我在SharePoint web部件项目中定义了两个参数,当用户从两个组合框(可浏览属性)中选择时,这些参数将传递到Silverlight应用程序中的应用程序_Startup()。不知何故,当我将Silverlight控件加载到SharePoint网站上时,它不会呈现。传入1个参数后,控件显示无错误。有什么想法吗?语法?例子 App.xaml.cs: private void Application_Startup(object sender, StartupEventArgs e) {

我在SharePoint web部件项目中定义了两个参数,当用户从两个组合框(可浏览属性)中选择时,这些参数将传递到Silverlight应用程序中的应用程序_Startup()。不知何故,当我将Silverlight控件加载到SharePoint网站上时,它不会呈现。传入1个参数后,控件显示无错误。有什么想法吗?语法?例子

App.xaml.cs:

private void Application_Startup(object sender, StartupEventArgs e)
{
    //testing
    string _setArticles = null;
    string _setLength = null;
    if (e.InitParams != null && e.InitParams.Count >= 1)
    {
        _setArticles = e.InitParams["_setArticles"];
        _setLength = e.InitParams["_setLength"];
    }
    this.RootVisual = new Page(_setArticles, _setLength);
}
Page.xaml.cs:

public Page(string _setArticles, string _setLength)
{
    InitializeComponent();

    //(number of items to display on load)
    if (!string.IsNullOrEmpty(_setArticles) && !string.IsNullOrEmpty(_setLength) )
    {
        if (_setArticles.Equals("_1_article"))                   
            retrieveOneListboxItemStaffNews();
            GetData3();
        if (_setArticles.Equals("_2_articles"))
            retrieveTwoListboxItemStaffNews();
            GetData3();
       if (_setArticles.Equals("_3_articles"))
            retrieveThreeListboxItemStaffNews();
            GetData3();

       //testing
       //send value to method 'fullNameControl_Loaded' (summary length of each ListBox item)                    
       if (_setLength.Equals("_3_lines"))
            m_textBlock.MaxHeight = 40;
       if (_setLength.Equals("_4_lines"))
            m_textBlock.MaxHeight = 50;
       if (_setLength.Equals("_5_lines"))
            m_textBlock.MaxHeight = 65;  
    }
}
SilverlightSecondWebPart.cs:

protected override void CreateChildControls()
{
    base.CreateChildControls();

    //silverlight control
    silverlightControl = new Silverlight();
    silverlightControl.ID = "News";
    silverlightControl.Source = "/ClientBin/News.xap";
    silverlightControl.Width = new System.Web.UI.WebControls.Unit(800);
    silverlightControl.Height = new System.Web.UI.WebControls.Unit(550);


    //testing
    string parameters =  "_setArticles=" + _myEnum + ", " + "_setLength=" + _myEnum2;
    silverlightControl.InitParameters = parameters;
    silverlightControl.MinimumVersion = "2.0";

    Controls.Add(silverlightControl);
}  
反正用

if (_setArticles.Equals("_1_article"))
{
    retrieveOneListboxItemStaffNews();
    GetData3();
}
if (_setArticles.Equals("_2_articles"))
{
    retrieveTwoListboxItemStaffNews();
    GetData3();
}
if (_setArticles.Equals("_3_articles"))
{
    retrieveThreeListboxItemStaffNews();
    GetData3();
}
否则将调用
GetData3()
,每次调用3次。

无论如何,请使用

if (_setArticles.Equals("_1_article"))
{
    retrieveOneListboxItemStaffNews();
    GetData3();
}
if (_setArticles.Equals("_2_articles"))
{
    retrieveTwoListboxItemStaffNews();
    GetData3();
}
if (_setArticles.Equals("_3_articles"))
{
    retrieveThreeListboxItemStaffNews();
    GetData3();
}

否则将调用
GetData3()
,每次调用3次。

感谢您的回复。您知道如何访问嵌入在datatemplate中的textblock吗?在线示例没有太大帮助,因为它涉及到在网格上指定一个x:key?感谢您的回复。您知道如何访问嵌入在datatemplate中的textblock吗?在线示例没有太大帮助,因为它涉及到在网格上指定x:key?
