How to set windowless for Silverlight business application

[Manoj]

I am using Silverlight business application. At home page using HtmlPlaceHolder. My home page url is as follows.

http://localhost:52878/HTMLPlaceHolderBusinessApplicationTestPage.aspx#/Home

-          How can I set ‘windowless=true’?

I have used following code from your example but not working for me.

if (!Application.Current.Host.Settings.Windowless)

                     {

                           string newUrl;

 

                           newUrl = HtmlPage.Document.DocumentUri.AbsoluteUri.Replace(HtmlPage.Document.DocumentUri.Fragment, string.Empty);

                           newUrl = string.Format("{0}?windowless=true{1}", newUrl, HtmlPage.Document.DocumentUri.Fragment);

 

                           HtmlPage.Window.Navigate(new Uri(newUrl, UriKind.Absolute));

                     }

Output of this code is http://localhost:52878/HTMLPlaceHolderBusinessApplicationTestPage.aspx?windowless=true#/Home

-          Can I open Asp.net page in HTMLPlaceHolder?

-          Can HtmlPlaceholder help in passing parameters to associated ASP.Net page.

Hi Manoj,

 Can I open Asp.net page in HTMLPlaceHolder? 

Yes, you can absolutely use an aspx page as a SourceUrl for RadHtmlPlaceholder.

Can HtmlPlaceholder help in passing parameters to associated ASP.Net page. 

Yes, you can pass parameters to the page which is displayed by RadHtmlPlaceholder. However, you need to make the page aware of parameters. For example, in our QSF the Default.aspx page has the following piece of code which is aware of the windowless parameter:

<div id="silverlightControlHost">
    <object data="data:application/x-silverlight-2," type="application/x-silverlight-2"
        width="100%" height="100%">
        <param name="source" value="<%= Examples.Web.Global.Version %>/Examples/QuickStartUI.xap" />
        <param name="onSourceDownloadProgressChanged" value="onSourceDownloadProgressChanged" />
        <param name="onError" value="onSilverlightError" />
        <param name="background" value="#f2f2f2" />
        <param name="minRuntimeVersion" value="4.0.50826.0" />
        <param name="autoUpgrade" value="true" />
        <param name="EnableRedrawRegions" value="false" />
        <% if (!string.IsNullOrEmpty(Request.QueryString["windowless"]))
           { %>
        <param name="windowless" value="true" />
        <% } %>
        <param name="HtmlAccessEnabled" value="true" />
    </object>
    <iframe id="_sl_historyFrame" style="visibility: hidden; height: 0px; width: 0px;
        border: 0px"></iframe>
</div>

Thanks Kiril. It is working for me.
It will be great if you provide few line of code for parameter passing/receiving from silverlight codebehind file to Asp.net page (embedded in HtmlPlaceholder).

Hello Manoj,

Actually the ASPX page within the HtmlPlaceholder should be aware of the URL and process it as it likes. The HtmlPlaceholder should only be setting the URL or it is something else you have in mind?

Uri

 

 

uri = new Uri(Application.Current.Host.Source, "../../ReportViewr.aspx");

 

 

 

this.htmlPlaceholder1.SourceUrl = uri;
