datalist EditItemTemplate 中控件问题

[qq348043275]

protected void dlFriend_EditCommand(object source, DataListCommandEventArgs e)
{
dlFriend.EditItemIndex = e.Item.ItemIndex;
dlFriendBound();
if (Session["userInfo"] == null)
{
ScriptManager.RegisterStartupScript(dlFriend, this.GetType(), "ddd", "<script>alert('登陆超时'); window.top.location.href='../login.aspx?returnUrl=admin/index.aspx?frame=friendmanager.aspx'</script>", false);
}
else
{
DropDownList ddl = (DropDownList)e.Item.FindControl("ddlFriendType");//找不到他
Sgw_Users user = Session["userInfo"] as Sgw_Users;
List<BlogFriendType> bft = BlogFriendTypeManager.selectByUserID(user.UserID);
ListItem li = new ListItem("我的好友", "我的好友");
if (bft == null)
{
ddl.Items.Add(li);
}
else
{
if (bft.Count == 0)
{
ddl.Items.Add(li);
}
else
{
ddl.DataSource = bft;
ddl.DataValueField = "id";
ddl.DataTextField = "typeName";
}
}
}
}现在的问题就是找不到控件...请教下是哪里出了问题？

没有控件? 重新生成解决方案

[happy664618843]

调试 看输出的值 有没有这控件 查看源代码

[happy664618843]

ddl.DataSource = bft;
ddl.DataValueField = "id";
ddl.DataTextField = "typeName";
ddl.DataBind()加上绑定

源代码也没控件
<asp:DataList ID="dlFriend" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow" DataKeyField="id" OnCancelCommand="dlFriend_CancelCommand" OnDeleteCommand="dlFriend_DeleteCommand"
OnEditCommand="dlFriend_EditCommand" OnUpdateCommand="dlFriend_UpdateCommand" >
<ItemTemplate>

<tr>
<td align="absMiddle" valign="middle"><img src='<%#getImg(Eval("friendID")) %>' width="50px" height="50px" align="absmiddle"/> <a href="../index.aspx?id=<%#Eval("friendID") %>" target="_blank"><%#getUserName(Eval("friendID")) %></a></td>

aspx代码这样的

[qq348043275]

就是点击编辑的时候 把其中一列dropdownlist 绑定数据源

问题解决(DropDownList)dlFriend.Items[e.Item.ItemIndex].FindControl("ddlFriendType");这样就可以了
