将主题从下拉菜单传递到另一个页面 [英] Passing Themes from a Drop Down to another page

问题描述

我正在尝试将主题从一个下拉列表传递到另一页.传递主题时，我希望将其应用于其他页面.这是我的DropDownList页面的代码，主题是我想传递的主题，如何在另一页面上接收它?

Themes.aspx.cs

I''m trying to pass themes from one drop down list to another page. When I pass the theme I want it to be applied to the other page. Here is my code for the DropDownList page with the theme I want to pass how do I receive it on the other page?

Themes.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Lab3_Themes : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        ListItem xLI0 = new ListItem("Standard","Standard.skin");
        ddlThemes.Items.Add(xLI0);
        ListItem xLI = new ListItem("Sunny");
        ddlThemes.Items.Add(xLI);
        ListItem xLI2 = new ListItem("Dark");
        ddlThemes.Items.Add(xLI2);
    }
    protected void btnApplyTheme_Click(object sender, EventArgs e)
    {
        Session.Add("Themes", ddlThemes.SelectedValue);
        Response.Redirect("Lab5.aspx");
    }
   

}

推荐答案

我意识到您只提供了一部分代码，但是主题可能不会改变，因为您的代码没有除了Standard.skin以外，什么都不能处理?

I realise you have only provided a portion of your code, but could it be that the theme isn''t changing because your code doesn''t handle anything other than Standard.skin?
