以下是我的代码,显示一个标题后跟一个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>
代码背后:
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;
}
问题只在于文字显示。 checkboxlist
未填写。
当response.write()
DataBind
checobxlist
方法{{1}}时,他们就出局了。
所以我的代码背后有效。但是有些东西不见了。但是我找不到什么。
答案 0 :(得分:1)
将DataSourceID更改为DataSource
<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSource=<%# FillinCbl(DataBinder.Eval(Container.DataItem,"ItemID").ToString()) %> DataTextField="ItemName" DataValueField="ItemValue">
