I need to convert my dropdown list to a dropdown checklist, so basically the item on the list is still the same but should have checkboxes on them. Thanks in advanced. Here's how it looks like: timg092191.wordpress/2013/08/16/ddcl/[^] Here's the code: From AddUser4.aspx

<asp:DropDownList ID="drpSchoolOffice" runat="server" Width="200px"> </asp:DropDownList>

来自AddUser4.aspx.cs

From AddUser4.aspx.cs

protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { try { drpSchoolOffice.Items.Clear(); dtOffice = blSchool.loadSchoolAll(); if (dtOffice.Rows.Count > 0) { foreach (DataRow r in dtOffice.Rows) { drpSchoolOffice.Items.Add(r[2].ToString()); } } SortedList slst = new SortedList(); foreach (ListItem li in drpSchoolOffice.Items) { slst.Add(li.Text, li.Value); } drpSchoolOffice.DataSource = slst; drpSchoolOffice.DataValueField = "Value"; drpSchoolOffice.DataTextField = "Key"; drpSchoolOffice.DataBind(); catch { Response.Redirect("~/index.aspx"); } } }
