Button获胜'；t触发方法

Title确实说明了一切。我按下了按钮，却什么也没想明白为什么。

Default.aspx标记(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
    }

添加表单

Button获胜'；t触发方法

为了结束这个问题，我正在写一个与OP沟通的答案(请参阅评论(

OP进行了几次更改，使其恢复了的功能

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：

我相信OP没有收到警报，因为他错过了<script>标签
