Question

I’m using the code below to grab a list of companies from my database and load them into a list view. It’s working great.

conn.Open();
string pricesqry = "SELECT company, url FROM companies";
SqlCommand pricescmd = new SqlCommand(pricesqry, conn);
SqlDataReader pricesreader = pricescmd.ExecuteReader();

while (pricesreader.Read())
{
    ListViewItem company = new ListViewItem(pricesreader["company"].ToString());
    company.SubItems.Add(pricesreader["url"].ToString());
    company.SubItems.Add("Blank for now..");

    pricesList.Items.Add(company);
}
conn.Close();

However, if I wanted to alphabetize my list by company names, by changing my select query to this:

string pricesqry = "SELECT company, url FROM companies ORDER BY company";

No data is loaded into the listview. Remove the order by section and the data appears again. What am I doing wrong?

Credit goes to Minitech.

My ‘Company’ column type was set to Text. Changed to varchar and it’s now working as I expected.
