Question

<asp:Panel ID="plOffice" runat="server" ScrollBars="Vertical" Width="200px" Height="80px" CssClass="TB">
    <asp:CheckBoxList ID="chkOffice" runat="server" AppendDataBoundItems="True" Height="80px" AutoPostBack="True" OnSelectedIndexChanged="chkOffice_SelectedIndexChanged">
        <asp:ListItem>All</asp:ListItem>
    </asp:CheckBoxList>

Dim DsStatus As New DataSet
D.FillDataSet(DsStatus, "select * from Z_AppStatusMaster")
ChkStatus.DataSource = DsStatus
ChkStatus.DataTextField = "StatusDescription"
ChkStatus.DataValueField = "AppStatusID"
ChkStatus.DataBind()

注意：将多个列值绑定到复选框列表。我需要将更多列值绑定到复选框列表。我已经在使用DataTextField和DataValueField ...

Answer 1

您可以自定义SQL查询，以便它准确地提供您要显示的内容：

D.FillDataSet(DsStatus, "select AppStatusID, StatusDescription + ' - ' + SomeOtherField as CustomDescription from Z_AppStatusMaster")
ChkStatus.DataSource = DsStatus
ChkStatus.DataTextField = "CustomDescription"
ChkStatus.DataValueField = "AppStatusID"

Answer 2

为此，您将需要创建一个从DropDownList继承的类，然后覆盖SaveViewState，LoadViewState和RenderContents子例程。

我无法发布我们的代码，因为它是专有的，但是我们先这样做，然后通过添加属性为每个项目添加其他值。例如：

   For Each dr In ds.Tables(1).Rows
        cbo.Items.Add(New System.Web.UI.WebControls.ListItem(dr("NAME"), dr("VALUE")))

        cbo.Items(cbo.Items.Count - 1).Attributes.Add("GROUP", dr("GROUP"))

    Next
