on Tag.ascx.cs file

public byte[] originalData;

protected void Page_Load( object sender, EventArgs e )
        {
            ITag tag = null;
            if (!String.IsNullOrEmpty(Request["Tag"]))
            {
                try
                {
                    int tagID = Int32.Parse(Request["Tag"], CultureInfo.InvariantCulture);
                    tag = TagFactory.GetITag(tagID);
                }
                catch (FormatException) { }
            }
            if (!IsPostBack)
            {
                if (tag != null)
                {
                    string TextData = "";
                    WebClient wc = new WebClient();
                  
                    string myTagUrl = String.Format(CultureInfo.InvariantCulture, "http://ec2-67-202-62-133.compute-1.amazonaws.com/index.php?key=8f6dd47c952c8c6b4937e345294cbc96&keyword={0}", tag.Name);

                    try
                    {
                        originalData = wc.DownloadData(myTagUrl);
                    }
                    catch (WebException)

                    rptTags.DataSource = dt;
                    rptTags.DataBind();
                  }
               }
            }
        }

Thank you again for always help from this site.

Awesome. Thank you very much for your help. :)

But I have more question need to ask.

what I want to show on my "Tag.ascx" file is Culture, Artist, Theater, Festival, Asian American, Diversity, PHOTOGRAPHY, HIP HOP, Theater, Film

those names are buttons, if the button is clicked, then gridview needs to be reloaded. Say "Culture" is clicked, it should go  "http://ec2-67-202-62-133.compute-1.amazonaws.com/index.php?key=8f6dd47c952c8c6b4937e345294cbc96&keyword=culture" to get the file, reload gridview again.

I have to use linkbutton,  but what is "ItemDataBound" at .cs file, I don't want to use bondfield at ascx file

Thank you,

ellen
