我的观点不会显示。他们正在展示，但他们突然不会出现，我不知道为什么。请帮忙/建议。

我不知道自己做错了什么。此外，我还不知道代码中是否包含CSS /样式，但它包含侧栏的代码。 C＃代码在
之下using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class index : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Top1_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 1;
}
protected void Tview1_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 0;
}
protected void Tview2_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 1;
}
protected void Tview3_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 2;
}
protected void Tview4_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 3;
}
protected void Tview5_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = 4;
}
}
我是C＃的新手，但我在网上学到了我认为这是正确的。
This is all the page comes up with. It didn't do this before but now it does, I don't know why.
答案 0 :(得分：-1)
我认为这可能只是因为LinkButton上没有OnClick事件。例如，更改：
<li><asp:LinkButton ID="Tview3" runat="server">iPhone 7</asp:LinkButton></li>
添加：
OnClick="Tview3_Click"
所以它变成了：
<li><asp:LinkButton ID="Tview3" runat="server" OnClick="Tview3_Click">iPhone 7</asp:LinkButton></li>
