动态更改主题为asp.net中的母版页 [英] Change theme dynamically to master pages in asp.net

问题描述

嗨

我必须对创建到主题的所有页面应用主题，一个是红色，另一个是橙色，如果我在下拉列表中进行了更改，则它仅显示默认红色，而这并没有改变我在母版页中实现的代码
我写了

Hi

I have to apply theme for all pages i created to themes one is red and another one is orange its showing only default red if i changed in dropdownlist it''s not changing i implemented code in master page
i wrote

protected void Page_PreInit(object sender, EventArgs e)
   {
       string thm;
       thm = (string)Session["themeSelected"];
       if (thm != null)
       {
           Page.Theme = thm;
           DropDownList1.Text = thm;
       }
       else
       {
           Session["themeSelected"] = DropDownList1.Text;
           Page.Theme = "Blue";
       }

   }

   protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
   {
       Session["themeSelected"] = DropDownList1.Text;
       Server.Transfer(Request.FilePath);
   }

在我更改了web.confing< pages主题="Orange">
之后 我在哪里弄错了?
