Question

I already have the datatable. I just need to fill it in the list view. The problem is that I’m running into this error:

‘System.Web.UI.WebControls.ListView’ does not contain a definition for ‘DisplayMember’ and no extension method ‘DisplayMember’ accepting a first argument of type ‘System.Web.UI.WebControls.ListView’ could be found (are you missing a using directive or an assembly reference?)

I thought the list view had a “DisplayMember” property? This is ASP .NET 4.0, by the way.

namespace Eagle_Replication_Manager
{
    public partial class wfrmMain : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //on page load, I want to get a database table and populate this list view: 
            lvItems.DataSource = GetSourceDBs();

            //This does not work, error here:
            lvItems.DisplayMember = "Description";
        }

        private DataTable GetSourceDBs()
        {
            using (SqlConnection conn = new SqlConnection(AppVars.connectionString))
            {
                using (SqlCommand cmd = new SqlCommand("SELECT [Description] FROM [Warehouse].[dbo].[Items]", conn))
                {
                    conn.Open();

                    cmd.ExecuteNonQuery();

                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        using (DataTable dt = new DataTable())
                        {
                            da.Fill(dt);
                            return dt;
                        }
                    }
                }
            }
        }
    }
}

This should work:

    protected void Page_Load(object sender, EventArgs e)
    {
        lvItems.DataSource = GetSourceDBs();
        lvItems.DataBind();
    }
