以下是我显示 One Title 后跟 one 的代码checkboxlist

标记:

<asp:Repeater id="repRoles" runat="server">
       <ItemTemplate>
              <asp:literal runat="server" text=<%# DataBinder.Eval(Container.DataItem, "ItemTitle") %>></asp:literal>
              <br />
              <asp:CheckBoxList runat="server" DataSourceID=<%# FillinCbl(DataBinder.Eval(Container.DataItem,"ItemID").ToString()) %> 
                                    DataTextField="ItemName" DataValueField="ItemValue">
              </asp:CheckBoxList>
       </ItemTemplate>
</asp:Repeater>

后面的代码:

private void FillinRepeater()
{
    try
    {
        List<Item> targetAudienceParent = new List<Item>();
        DataTable tempTbl = new DataTable();
        tempTbl.Columns.Add("ItemTitle", typeof(String));
        tempTbl.Columns.Add("ItemID", typeof(String));
        DataRow tempRow;
        int tempCount = 0;
        foreach (Item a in itmECM.Children)
        {
            try
            {
                tempRow = tempTbl.NewRow();
                tempRow["ItemTitle"] = a.Name.ToString();
                tempRow["ItemID"] = a.ID.ToString();
                tempTbl.Rows.Add(tempRow);
                tempCount++;
            }
            catch
            {
            }
        }
        repRoles.DataSource = tempTbl;
        repRoles.DataBind();
    }
    catch
    {
    }
}
public DataTable FillinCbl(String passedString)
{
    dtlRoles = new DataTable();
    dtlRoles.Columns.Add("Name", typeof(String));
    dtlRoles.Columns.Add("OptInID", typeof(String));
    dtlRoles.Columns.Add("OptOutID", typeof(String));
    Item tempItm = master.GetItem(passedString);
    DataTable tempTbl = new DataTable();
    tempTbl.Columns.Add("ItemName", typeof(String));
    tempTbl.Columns.Add("ItemValue", typeof(String));
    DataRow tempRow;
    try
    {
        populateUsersList(tempItm);
        Session["dtlRoles"] = dtlRoles;
        for (int a = 0; a < dtlRoles.Rows.Count; a++)
        {
            try
            {
                Response.Write(dtlRoles.Rows[a][0].ToString().Trim() + "<br/>");
                tempRow = tempTbl.NewRow();
                tempRow["ItemName"] = dtlRoles.Rows[a][0].ToString().Trim();
                tempRow["ItemValue"] = dtlRoles.Rows[a][1].ToString().Trim();
                tempTbl.Rows.Add(tempRow);
            }
            catch(Exception ex1)
            {
                Response.Write(ex1.ToString() + "<br/>");
            }
        }
    }
    catch (Exception ex2)
    {
        Response.Write(ex2.ToString() + "<br/>");
    }
    return tempTbl;
}

问题只是文字显示。checkboxlist没有填写。

当我response.write()为我的DataBind方法为checobxlist他们出局的时候。

所以我背后的代码正在工作。不过还是少了点什么。但我不知道是什么。

将 DataSourceID 更改为 DataSource

<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSource=<%# FillinCbl(DataBinder.Eval(Container.DataItem,"ItemID").ToString()) %>  DataTextField="ItemName" DataValueField="ItemValue">
