I have a CheckBoxList on my ASP.Net page. I'm loading it like this:

private void _UserSelected()
{
    lstRights.Items.Clear();
    lstRights.Font.Name = "Arial";
    lstRights.Font.Bold = false;
    lstRights.Font.Size = 10;
    lstRights.TextAlign = TextAlign.Left;

    int UserKey = Convert.ToInt32(cboUsers.SelectedValue);

    csUser User = new csUser();
    User.RecordKey = UserKey;
    User.LoadData();

    DataSet dsRights = User.RightsTable;

    lstRights.DataSource = dsRights.Tables[0];
    lstRights.DataTextField = "RightName";
    lstRights.DataBind();
}

There are only 4 items, which is ok, but each item is centered in the list, and each row is separated from the other alot, almost like
there's blank rows in between each.

I have not changed any settings in this control, other than what's in this method.

What am I doing wrong here?
