Question

Silverlight plugin to Determine Page Height?

Answer 1

A:

The behavior you're facing is due to the limits the HTML sets on the control. It can be solved by placing height of 100% on all containers hierarchy in advance and notify the body element when the size of the control changes:

HTML For example:

<html xmlns="http://www.w3.org/1999/xhtml" style="height:100%;">
<head runat="server">
    <title>SilverlightApplication1</title>
</head>
<body style="height:100%;margin:0;">
    <form id="form1" runat="server" style="height:100%;">
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        <div  style="height:100%;">
            <asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/SilverlightApplication1.xap" MinimumVersion="2.0.31005.0" Width="100%" Height="100%" />
        </div>
    </form>
</body>
</html>

And the notification in the control code behind:

public Page()
{
    InitializeComponent();
    SizeChanged += new SizeChangedEventHandler(Page_SizeChanged);

}

void Page_SizeChanged(object sender, SizeChangedEventArgs e)
{
    HtmlPage.Document.Body.SetStyleAttribute("height", e.NewSize.Height + "px");
}

This is semi working... problem is that I am using teh RIA Framework and the User control (which is the master page) gets the size of the windows again... I have to do this on the inner-pages and then add onto the size to take into account for the banner and various other elements on the master form.Advice?

Answer 2

A:

This is what I did eventually, It's far from perfect but maybe someone can take it and improve it:

 private void Page_SizeChanged(object sender, SizeChangedEventArgs e)
    {
        BrowserInformation oInfo = System.Windows.Browser.HtmlPage.BrowserInformation;

        double nHeight=0;
        if (oInfo.Name.ToLower().Contains("explorer"))
        {
            nHeight = (double)HtmlPage.Document.DocumentElement.GetProperty("clientHeight");
        }
        else if (oInfo.Name.ToLower().Contains("netscape"))
        {
            nHeight = (double)HtmlPage.Window.GetProperty("innerHeight");
        }


        if ((e.NewSize.Height + 160) > nHeight)
        {
            HtmlPage.Document.Body.SetStyleAttribute("height", (e.NewSize.Height + 160) + "px");
        }
        else
        {
            HtmlPage.Document.Body.RemoveAttribute("style");
        }
    }
