Question

标题真的说明了一切。我按下按钮，没有任何反应试图找出原因。

Default.aspx标记（在表单范围内）

 <div class="form-group">
     <div style="text-align:center">
        <asp:Button input type="submit" class="btn btn-default btn-lg" align="center"  runat="server" OnClick="btnSubmit_Click" Text="Submit"/>
     </div>
 </div>

Default.aspx代码

 protected void btnSubmit_Click(object sender, EventArgs e)
    {
        SqlConnection conn = new SqlConnection();

        ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('Connected to ASPX file');", true); 
        //...rest of code
    }

已添加表格

Answer 1

刚刚结束这个问题，我正在通过与OP的沟通写出答案（请参阅评论）

对OP进行了一些改变以获得回发功能

将按钮HTML更改为

<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" CssClass="btn btn-default btn-lg" />

将警报脚本更改为

ClientScript.RegisterClientScriptBlock(this.GetType(), "myalert", "<script>alert('Connected to ASPX file');</script>");

编辑：

我认为OP没有得到提醒，因为他错过了<script>标签

按钮不会触发方法
