Silverlight Integration in MOSS 2007 with out WebPart


In this article I will walk you through how you can integrate a Silverlight application in Sharepoint with out using any webpart. (Download the STP file)



I will use one of  my existing silverlight slide show application for this demo..

Upload your silverlight related files in the sharepoint repository,  here I  am uploading Silvrlight.js, Silverlight XAP file  and images folder in the Shared Document library


The next step is open the website in  SPD (Sharepoint Designer) and create a aspx page under Shared Documents library and add some markup code inside the content place holder (PlaceHolderMain) and copy paste the silverlight object and javascript code.

Save & preview the page in browser you should be able to see your Silverlight application running inside  Sharepoint..

Download the STP file

Hope this help and If you have any comments, please feel free to write your feedback.

Thanks

Twitter Tweets in Asp.Net C#


I’ve been working on the twitter feed in one of my recent project where tweets getting updated on a regular interval time (say for every 30 minutes or 1 hr). I am creating this as a ASCX control so that I can reuse for multiple projects.

You can Download the complete source code from here

I am dropping a ListView control in the ASCX page which render the Twitter Profile name along with  Title, Description and Published date for the latest tweets.

Couple of properties need to configure to use this control

TwitterProfileName – Your twitter profile name or screen name

TweetsCount – No of tweets you want to return (default is 10).

<asp:ListView ID="lvTweets" runat="server">
<LayoutTemplate>
<table border="0" cellpadding="2" cellspacing="0">
<tr>
<td height="30" runat="server">
<a href="http://twitter.com/<%=<span class=&quot;hiddenSpellError&quot; pre=&quot;&quot;>TwitterProfileName</span>%>" target="_new"></a>
<%= TwitterProfileName%>
</td>
</tr>
<tr>
<td>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</td>
</tr>
<tr>
77B5D2;">
</td>
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td>
<a target="_new" href='<%# DataBinder.Eval(Container.DataItem, "Link")%>'>
<%# DataBinder.Eval(Container.DataItem, "Title")%></a>
<br />
<div>
<%# DataBinder.Eval(Container.DataItem, "PublishedDate", "{0:h:mm  tt MMM d}")%>
</td>
</tr>
</ItemTemplate>
<EmptyDataTemplate>
<div>
<h3>
No tweets available.</h3>
</div>
</EmptyDataTemplate>
<ItemSeparatorTemplate>
<tr>
1px solid lightgrey;">
</td>
</tr>
</ItemSeparatorTemplate>
</asp:ListView>
