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>

</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>

</tr>
</ItemSeparatorTemplate>

  1. Hi,

    I am getting following error.

    Rate limit exceeded. Clients may not make more than 150 requests per hour. Please how can i solve this problem.

  2. Hi,

    This shows only last 5 tweets…how to show all tweets…

    Also what if i want to show my entire timeline.ie. my tweets + following people’s tweets…

  3. Getting this error – Rate limit exceeded. Clients may not make more than 150 requests per hour. even after setting the cache limit to 60 minute, the error still comes.
    kindly give any solution to this..it is very annoying…

  4. Awesome post! I was able to implement your code and then fully customize it for my site’s purposes. I’d first tried Twitter’s own widget but ran into conflicts between the widget and my asp:menu. Yours works just fine.

    Thanks
    Phil

    1. Caching is already implemented in the LoadXML() method…

      private XDocument LoadXML()
      {
      if (xDoc != null && !IsTimeForUpdate)
      {
      return xDoc;
      }
      else
      {
      try
      {
      TweetsCount = TweetsCount.HasValue ? TweetsCount : 10;
      var url = string.Format(“http://api.twitter.com/statuses/user_timeline.rss?screen_name={0}&count={1}”, TwitterProfileName, TweetsCount);
      xDoc = XDocument.Load(url);
      lastUpdated = DateTime.Now;
      return xDoc;
      }
      catch
      {
      return null;
      }
      }

      By default the tweets will be cached for 10 minutes every 10 minutes this will be reloaded from server. If you want to exceed the interval.. change the member variable Interval 10 to 30 or 60….120.

      private static Double Interval = 30;

      Hope this helps

  8. Hey there,

    Once I download your sample code, am I supposed to be able to run it? I have not changed any coding from your sample code, however when I run it the page shows “No tweets available”. Kindly advise.

    Thank you

      1. could you please give code for update status into twitter. what ever i tried i could not able to update the status in twitter.

        Thanks
        Sarathy

  9. The bellow code i was used

    // encode the username/password
    string user = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(Username + “:” + Password));
    // determine what we want to upload as a status
    byte[] bytes = System.Text.Encoding.ASCII.GetBytes(“status=” + message);
    // connect with the update page
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(“https://twitter.com/?update”);//https://twitter.com/statuses/update
    //http://twitter.com/statuses///update.xml //?statuses/update.xml
    // set the method to POST
    request.Method = “POST”;
    request.ServicePoint.Expect100Continue = false; // thanks to argodev for this recent change!
    // set the authorisation levels
    request.Headers.Add(“Authorization”, “Basic ” + user);
    request.ContentType = “application/x-www-form-urlencoded”;
    // set the length of the content
    request.ContentLength = bytes.Length;

    // set up the stream
    Stream reqStream = request.GetRequestStream();
    // write to the stream
    reqStream.Write(bytes, 0, bytes.Length);
    // close the stream
    reqStream.Close();

    //request.Abort
    try
    {
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    }
