【问题描述】：
我是 vb 中 ASP.NET 的新手。我使用 Visual Studio 2010。
我下载了一个引导程序并将其转换为 .aspx（我将 index.html 更改为 index.aspx）。每当我从工具箱中拖动一个按钮时，我都会收到此消息“插入 asp.net 控件会将页面中的 HTML 转换为 ASP.NET 表单并删除其当前属性。是否要插入 ASP.NET 控件？”。
当我单击“是”时，按钮可以工作，但设计确实搞砸了。侧边菜单图标变大了。
我尝试手动编码其中的按钮
<div class="row no-padding">
按钮的代码
<asp:Button ID="Button1" CssClass="btn-primary" runat="server" Text="Login" />
我有一个按钮，即使它有一个回发网址，但它的设计仍然很好。
我还尝试将其转换为母版页并包含内容占位符，但结果相同。
这是我的全部代码（它不是母版页）。
