Hi,
I am trying to get code to read from RSS Feed to a GridView in ASP.Net VB & C#
I looked at the following:
http://www.experts-exchange.com/Programming/Languages/C_Sharp/Q_23438677.html
I have made some alterations to the existing, but am still getting errors.
I have the c# code in App_Code folder CSCode
VB code in App_Code folder VBCode
and referenced the folders in Web.config as follows:
<codeSubDirectories><add directoryName="VBCode"/><add directoryName="CSCode"/>

C# Code First:
using System;
using System.Data;
using System.Data.SqlClient;
using System.Web.Configuration;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
 
public partial class rssCS : System.Web.UI.Page
{
 
    protected void Page_Load(object sender, EventArgs e)
    {
        GridView.DataSource = GetDataSet().Tables[3];
        GridView.DataBind();
    }
    private DataSet GetDataSet()
        
    {
        DataSet ds = new DataSet("rsRSS");
        ds.ReadXml("http://rss.news.yahoo.com/rss/mostviewed");
        GridView.DataMember = "item";
        GridView.DataSource = ds;
        //GridView1.DataBind();
        return ds;
    }
 
 
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        GridViewRow row = e.Row;
        DateTime CurrTime = DateTime.Now.Date;
 
        if (row.RowIndex >= 0) // Start looping on the first row
            if (row.RowType == DataControlRowType.DataRow)
            {
                row.Cells[0].Text = row.Cells[0].Text;
                row.Cells[1].Text = row.Cells[1].Text;
            }
 
        }
 
 
}
