我想在DataGrid的模板列里加入CheckBoxList,而这个CheckBoxList的item个数又是根据数据库查出的，请问怎么实现？

[gfz]

请给详细说明和代码！

1。
<asp:TemplateColumn>
<ItemTemplate>中
<asp:CheckBoxList id=cbl_test runat=server/>

2。
OnItemDataBound中

CheckBoxList cbl=(CheckBoxList)e.Item.FindControl("cbl_test");
if(cbl!=null){
cbl.DataSource = sth;
cbl.DataBind();
}

[gfz]

请再详细些！在cs文件中怎么实现？

[buaawjh]

OnItemDataBound事件中
dim cbl as checkboxlist

cbl=e.item.findcontrol("checkboxlist1")
cbl.datasource=...
cbl.DataTextField="id"
cbl.DataValueField="name"
cbl.databound()

也许对你有启发。
我用的是自定义控件，在摸班中嵌套了控件（菜单-》子菜单-》菜单项）

<%@ Control Language="C#" Debug="true" %>
<%@ Register TagPrefix="lei" TagName="menuitem" Src="UserLayerSubMenuObject.ascx" %>
<%@ import Namespace="System" %>
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.SqlClient" %>
<%@ import Namespace="System.Reflection" %>
<%@ import Namespace="Lei.BusinessLayer" %>
<script runat="server">

// Insert user control code here
//
public string MenuUserClientID="0";
public string MenuUserRoleNo="0";
public string MenuUserParentNo="0";

void BindMenu()
{
string sqlStr = "status = 1 and parentNo = "+MenuUserParentNo;
sqlStr += " and ( menuNo in (select parentNo from t_menulayout where menuNo in (select parentNo from v_menugrants where clientID = '"+this.MenuUserClientID+"' and roleNo = " + this.MenuUserRoleNo+"))";
sqlStr += " or menuNo in (select parentNo from v_menugrants where clientID = '"+this.MenuUserClientID+"' and roleNo = " + this.MenuUserRoleNo+"))";

MenulayoutObject userObj = new MenulayoutObject();
DataSet userData = userObj.GetData(sqlStr);
MenuDataList.DataSource = userData.Tables[0].DefaultView;
MenuDataList.DataBind();
}

void Page_Load(Object Sender, EventArgs E)
{
//if (!Page.IsPostBack)
{
//if(UserClientID.Length>0 && RoleNo.Length>0)
BindMenu();
}
}
</script>
<asp:Repeater id="MenuDataList" runat="server">
<ItemTemplate>
<div class="<%#DataBinder.Eval(Container.DataItem, "leaf").ToString()=="1"?"tbMenuItem":"tbMenu"%>"
id="Menu_<%#DataBinder.Eval(Container.DataItem, "menuNo")%>" LANGUAGE="javascript"

</div>
</ItemTemplate>
</asp:Repeater>
</div>
