Question

请帮忙。我有以下 - ListView及其两个处理程序AdminUsersListView_ItemEditing，AdminUsersListView_Load。

<asp:ListView ID="AdminUsersListView" runat="server" 
     onitemediting="AdminUsersListView_ItemEditing" onload="AdminUsersListView_Load"
     DataKeyNames="UserId">
        <LayoutTemplate>
          <table cellpadding="2" runat="server" id="usersTable">
            <tr runat="server" id="itemPlaceholder" />
          </table>
        </LayoutTemplate>
        <ItemTemplate>
          <tr>
            <td><asp:LinkButton ID="EditButton" runat="server" Text="Edit" CommandName="Edit" /></td>
            <td><asp:Label ID="NameLabel" runat="server" Text='<%# Eval("UserName") %>' /></td>
          </tr>
        </ItemTemplate>
        <EditItemTemplate>
          <tr>
            <td><asp:LinkButton ID="UpdateButton" runat="server" CommandName="Update" Text="Update" /><asp:LinkButton ID="CancelButton" runat="server" CommandName="Cancel" Text="Cancel" /></td>
            <td><asp:Label runat="server" ID="NameLabel" AssociatedControlID="NameTextBox" Text="Name"/><asp:TextBox ID="NameTextBox" runat="server" Text='<%# Bind("UserName") %>' MaxLength="50" /></td>
          </tr>
        </EditItemTemplate>
    </asp:ListView>

编译完成后，我会看到常用的页面，每个行都有表格和编辑按钮，我点击按钮，发回的内容正在发送但没有发生任何事情。

处理程序如下：

protected void AdminUsersListView_ItemEditing(Object sender, ListViewEditEventArgs e)
{
}

protected void AdminUsersListView_Load(Object sender, EventArgs e)
{
    try
    {
         Int32 itemCount = Request["itemCount"] == null ? 10 : Int32.Parse(Request["itemCount"]);
         Int32 itemPage = Request["itemPage"] == null ? 0 : Int32.Parse(Request["itemPage"]);
         List<String> currentRoleList = Roles.GetRolesForUser().ToList();
         UsersManager usersManager = new UsersManager();
         IEnumerable<DbDataRecord> userList = usersManager.getAllowedUsersForRole(currentRoleList).ToList();
         userList = userList.Skip(itemCount * itemPage).Take(itemCount);
         AdminUsersListView.DataSource = userList;
         AdminUsersListView.DataBind();
    }
    catch (Exception exceptionData)
    {
         Log.setMessage(exceptionData);
    }
}

问题 - 为什么我总是看到ItemTemplate而看不到EditTemplate？

提前致谢，Art。

Answer 1

您可以尝试使用load事件进行数据绑定吗？

Answer 2

答案是直接设置编辑项目/行的索引，如下所示：

protected void lvwCustomers_ItemEditing(object sender, ListViewEditEventArgs e)
{
    CloseInsert();
    lvwCustomers.EditIndex = e.NewEditIndex;
    BindList();
}

ListView的EditTemplate不适用
