具有动态高度的Silverlight

标签: silverlight height

我有一个Silverlight应用程序,我希望允许像常规HTML页面一样大小。也就是说,我希望silverlight插件的大小能够在高度上扩展和收缩,以适应我填充Silverlight应用程序的动态数据和控件。所以,假设我有一个带有网格和按钮的页面。用户点击按钮,网格获得一堆行,图像使网格的自然大小高于浏览器窗口。我想有一些东西来调整silverlight插件的大小以适应网格的DesiredSize。以下以及其他一些尝试都无效:

// handler in my main page.
 void MainGrid_LayoutUpdated(object sender, EventArgs e)
 {
     HtmlPage.Window.Invoke("setSilverlightSize", this.MainGrid.DesiredSize.Height);
 }

<body style="height:100%;margin:0;">
    <form id="mainForm" runat="server" style="height:100%;">
        <asp:ScriptManager ID="ScriptManager" runat="server"></asp:ScriptManager>
        <div id="SilverlightContainer"  style="height:100%;">
            <asp:Silverlight ID="SLMain" runat="server" Source="~/ClientBin/My.Silverlight.Main.xap" Version="2.0" Width="100%" Height="100%" />
        </div>
    </form>
    <script type="text/javascript">
        function setSilverlightSize(val) {
            var host = document.getElementById("SilverlightContainer");
            host.style.height = val + "px";
        }
    </script>
</body>

MainGrid的所需大小始终希望是窗口的大小。阿格说海盗。

  1. 将溢出设置为“自动”
  2. 将滚动条设为“no”
  3. 将边距设为“0”
  4. 将包含div的宽度和高度设置为“100%”
  5. 将Silverlight控件的宽度和高度设置为“100%”
  6. 这应涵盖所有基础。请参阅下面的HTML示例。

    试试这个:

    <style type="text/css"> 
    html, body { overflow:auto } 
    </style>
    <head>
        <title>My App</title>
    </head>
    <body id="bodyId" style="margin:0;" scroll="no">
        <form id="form1" runat="server">
            <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
             <div style="position: fixed; height: 100%; width: 100%">
                <avn:Silverlight 
                    ID="xamlHost" 
                    runat="server" 
                    Source="~/ClientBin/THE.xap" 
                    MinimumVersion="x.x.xxxxx" 
                    Width="100%" 
                    Height="100%" 
                    />
             </div>
        </form>
    </body>
    </html>

我用过这个,似乎效果很好。需要获得渲染“ed”大小。

private void LayoutRoot_LayoutUpdated(object sender, System.EventArgs e)
{
    // Set the size of the SL object to the new rendered size of the Grid.
    ResizeSilverlightOnject(this.LayoutRoot.RenderSize.Height);
}

private void ResizeSilverlightObject( double height )
{
    HtmlPage.Window.Invoke( "ResizeObject", new object[] { height } );
}

在我的情况下,我创建了一个事件,并将高度数据发送到浏览器以处理来自javascript的高度值 这是我的HTML代码:

/*
When Silverlight is loaded attach silverlight events
*/
function OnSilverlightLoaded(sender, args) {
    //Getting Silverlight object on page
    _silverlightControlHost = document.getElementById("SilverlightObject");
    //Subscribe to it events
    _silverlightControlHost.Content.SilverlightApp.SetHeightEvent = SetHeightEvent;
}

这是我的Silverlight代码:

[ScriptableType]
public partial class MainPage
{
    //Register the event to be as accessible from script
    [ScriptableMember]
    public event EventHandler<HeightEventHandler> SetHeightEvent;

    public MainPage()
    {
        InitializeComponent();

        //Register this instance to be accessible from script
        HtmlPage.RegisterScriptableObject("SilverlightApp", this);
    }

    public void SomeMethod()
    {
        if (this.SetHeightEvent != null)
            this.SetHeightEvent(this, new HeightEventHandler() { Altura = _heightSilverObj.ToString() });
    }
}

[ScriptableType]
public class HeightEventHandler : EventArgs
{
    public string Altura { get; set; }
}

这很有用!

如果您尝试使用验证摘要确定高度(与此问题略有不同,但很有用),请尝试以下操作: 在Page.xaml.cs中 //将原始高度存储在Page_Loaded事件

void Page_Loaded(object sender, RoutedEventArgs e)
{
        SetupPage();
        this.ValidationSummary.SizeChanged += new SizeChangedEventHandler(ValidationSummary_SizeChanged);
}
void ValidationSummary_SizeChanged(object sender, SizeChangedEventArgs e)
    {
        if (this.OriginalPageHeight == 0.0)
        {
            this.OriginalPageHeight = this.RenderSize.Height;
        }
        else
        {
            double expandSize = this.OriginalPageHeight + e.NewSize.Height;
            ResizeSilverlightObject(expandSize);
        }
    }

编辑:添加了Javascript函数和cs函数

    function ResizeObject(height) {
        var host = document.getElementById("uploaderHost");
        host.style.height = height + "px";
    }

public void ResizeSilverlightObject(double height)
    {
       HtmlPage.HtmlWindow.Invoke("ResizeObject", new object[] { height });

    }
