Question

I’m trying to write a web application with some database interaction in C#.NET. I’m getting an odd exception that I can’t figure out where it’s coming from. I found the method that it is coming from and the code is as follows:

protected void cmdDelete_Click(object sender, EventArgs e)
{
    using (SqlConnection conn = new SqlConnection(@"Server=myname-PC\SQLEXPRESS;Database=dbNames;Trusted_Connection=True;"))
    {
        try
        {
            conn.Open();
            SqlCommand comm = new SqlCommand("DELETE FROM Names WHERE FirstName=@FirstName AND LastName=@LastName", conn);
            char[] delims = new char[1];
            delims[0] = ' ';

            string[] names = cblNames.SelectedItem.Text.Split(delims);
            string fname = names[0];
            string lname = names[1];
            comm.Parameters.Add(new SqlParameter("@FirstName", fname));
            comm.Parameters.Add(new SqlParameter("@LastName", lname));
            comm.ExecuteNonQuery();
            conn.Close();
            cblNames.ClearSelection();
            LoadTable();
        }
        catch (Exception ex)
        {
            Response.Write("Delete Table: "+ex.Message);
        }
    }
}

Any help is appreciated!

The problem that I was having was that I wasn’t getting the value on postback because I was leaving this little peace of code out of the page_load function:

If Not IsPostBack()

It was an elementary lapse in knowledge. I have been developing in .NET since this question and I realize how horribly simple it is to make mistakes in a new language. Thank you everyone for dealing with the past noob me.
