带有子菜单项的asp.net菜单，由代码隐藏重定向

Question

我有一个2级菜单项的菜单控件！我想通过OnMenuItemClick事件背后的代码导航，因为当我使用NavigationUrl属性时，我的ajax UpdateProgress将无法启动！

问题是，无论我单击什么子菜单项，当事件引发时，它每次都会得到第一个菜单项？！

<asp:Menu ID="Menu1" runat="server" onmenuitemclick="Menu1_MenuItemClick" >
...
    <Items>
    <asp:MenuItem Text="WorkFlows">
    <asp:MenuItem Text="Overview" Value="Workflow"></asp:MenuItem>
    <asp:MenuItem Text="Edit" Value="Workflow"></asp:MenuItem>
    <asp:MenuItem Text="Create" Value="Workflow"></asp:MenuItem>
    <asp:MenuItem Text="Delete" Value="Workflow"></asp:MenuItem>
    </asp:MenuItem>

    <asp:MenuItem Text="HoursOfBusiness">
    <asp:MenuItem Text="Overview" Value="HoursOfBusiness"></asp:MenuItem>
    <asp:MenuItem Text="Edit" Value="HoursOfBusiness"></asp:MenuItem>
    <asp:MenuItem Text="Create" Value="HoursOfBusiness"></asp:MenuItem>
    <asp:MenuItem Text="Delete" Value="HoursOfBusiness"></asp:MenuItem>
    </asp:MenuItem>


    </Items>
    </asp:Menu>

protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
        {

            switch (e.Item.Value)
            {
                case "Workflow":
                    switch (e.Item.Text)
                    {
                        case "Overview":
                            Response.Redirect("~/RGS/Workflow/Workflow.aspx");
                            break;
                            case "Edit":
                            Response.Redirect("~/RGS/Workflow/WorkflowEdit.aspx");
                            break;
                            case "Create":
                            Response.Redirect("~/RGS/Workflow/WorkflowCreate.aspx");
                            break;
                            case "Delete":
                            Response.Redirect("~/RGS/Workflow/WorkflowDelete.aspx");
                            break;
                    }
                    break;
                case "HoursOfBusiness":
                    switch (e.Item.Text)
                    {
                        case "Overview":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHours.aspx");
                            break;
                        case "Edit":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHours.aspx");
                            break;
                        case "Create":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHoursCreate.aspx");
                            break;
                        case "Delete":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHours.aspx");
                            break;
                    }
                    break;
            }

所以当我单击HoursOfBusiness下的Create时，我得到了发送到事件的概述menuItem？！我希望这个解释是可以理解的？！:-)

Answer 1

这就是我解决这个问题的方法：

<asp:Menu ID="Menu1" runat="server" OnMenuItemClick="Menu1_MenuItemClick">
    <Items>
        <asp:MenuItem Text="WorkFlows">
            <asp:MenuItem Text="Overview" />
            <asp:MenuItem Text="Edit" />
            <asp:MenuItem Text="Create" />
            <asp:MenuItem Text="Delete" />
        </asp:MenuItem>
        <asp:MenuItem Text="HoursOfBusiness">
            <asp:MenuItem Text="Overview" />
            <asp:MenuItem Text="Edit" />
            <asp:MenuItem Text="Create" />
            <asp:MenuItem Text="Delete" />
        </asp:MenuItem>
    </Items>
</asp:Menu>

后面的代码如下：

protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
{
    bool hasParent = (e.Item.Parent != null);

    switch (hasParent)
    {
        case false:
            switch (e.Item.Value)
            {
                case "WorkFlows":
                    Response.Redirect("~/RGS/Workflow/Workflow.aspx");
                    break;
                case "HoursOfBusiness":
                    Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHours.aspx");
                    break;
            }
            break;
        case true:
            switch (e.Item.Parent.Value)
            {
                case "WorkFlows":
                    switch (e.Item.Value)
                    {
                        case "Overview":
                            Response.Redirect("~/RGS/Workflow/Workflow.aspx");
                            break;
                        case "Edit":
                            Response.Redirect("~/RGS/Workflow/WorkflowEdit.aspx");
                            break;
                        case "Create":
                            Response.Redirect("~/RGS/Workflow/WorkflowCreate.aspx");
                            break;
                        case "Delete":
                            Response.Redirect("~/RGS/Workflow/WorkflowDelete.aspx");
                            break;
                    }
                    break;
                case "HoursOfBusiness":
                    switch (e.Item.Value)
                    {
                        case "Overview":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHours.aspx");
                            break;
                        case "Edit":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHours.aspx");
                            break;
                        case "Create":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHoursCreate.aspx");
                            break;
                        case "Delete":
                            Response.Redirect("~/RGS/Workflow/BusinessHour/BusinessHours.aspx");
                            break;
                    }
                    break;
            }
            break;

    }
}

希望这能帮助你解决你的问题。
