Question

I am trying to populate my listbox and can only populate it with System.Data.Datarow 5 times, witch is the amount of entry’s i have in my database.

I need my list box to be linked with my Database so that i can use it to select items to make changes to, so don’t want to just populate it but rather bind it.

I can’t seem to find ValueMember and DisplayMember properties. I think this may be because i’m Programming in webForms.

My Code:

using (var conn = new SqlConnection(Properties.Settings.Default.DBConnectionString))
{
      conn.Open();

      SqlDataAdapter daTags = new SqlDataAdapter("Select * From Tag", conn);

      DataSet dsTags = new DataSet("TagCloud");

      daTags.FillSchema(dsTags, SchemaType.Source, "Tag");
      daTags.Fill(dsTags, "Tag");

      daTags.MissingSchemaAction = MissingSchemaAction.AddWithKey;
      daTags.Fill(dsTags, "Tag");

      DataTable tblTag;
      tblTag = dsTags.Tables["Tag"];

      dplTags.DataSource = dsTags;
      dplTags.DataMember = "Tag"; 
      dplTags.DataBind();
 }

You should also specify the DataValueField(ValueMember) and DataTextField(DisplayMember) properties.
