按鈕將不會觸發方法

-1

標題確實說明了一切。我按下按鈕，沒有任何反應，試圖找出原因。按鈕將不會觸發方法

Default.aspx的標記（在表格範圍）

<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的代碼

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 
    }

新增形式

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 

<!DOCTYPE html> 

<html xmlns="http://www.w3.org/1999/xhtml">

     <br>

    </form>

'runat = server'？在'Button' – techspider

@techspider複製一箇舊版本的有壽... – Javant

什麼'input'屬性和'align'屬性？你沒有'ID'！你確定你知道你在寫什麼嗎？ – techspider

就關閉這個問題，我在我與OP的溝通中寫下答案（請參閱評論）

一些改動工作了OP獲得功能

更改按鈕HTML回發到

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

更改警報腳本

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

編輯：

我相信OP沒有得到警報，因爲他錯過了<script>標籤
