Only show X rows from DataGrid

Question

Hi, I want to post my 5 recent twitters on my website. I've build a datagrid with XMLTextReader in C# which reads the feed but the problem I face is that it shows ALL the feeds and I can't find a way to only show 5. Any idea's?

        XmlTextReader reader = new XmlTextReader("http://some.rss/feed.rss");
        DataSet ds = new DataSet();
        ds.ReadXml(reader);
        dg.DataSource = ds.Tables[2];
        dg.AutoGenerateColumns = false;
        dg.AllowPaging = false;
        dg.DataBind();

Answer 1

How about the simple solution of manually deleting all the rows from the DataTable except the first 5?

Answer 2

Better still, the Twitter API allows you to specify a "since ID" value. That way you can request only updates since the latest one you have.

Answer 3

to answer directly your question:

<asp:GridView ID="gv" runat="server"
              PageSize="5" AllowPaging="true">
   <PagerSettings Visible="false" />
</asp:GridView>

But I'm just wondering, why not trying to use a C# wrapper for Twitter API?

P.S. add twitter to your tags!
