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: http://timg092191.wordpress.com/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");
}
}
}
