单击按钮时，如何在txtbox中显示总记录数 [英] How do I show total record no in a txtbox when button is clicked

问题描述

我是c＃sql的新手，我想显示已经输入数据库的总数记录。

这里是代码

 <   label    < span class =code-attribute> class   =  col-sm-3 >  
计数：
 <   / label  >  
 <   div     class   =   col-sm-2 >  
 <   asp：TextBox     runat   =   server    ID   =  txtCount    AutoPostBack   =  true >  <   / asp：TextBox  >  
 <   asp：按钮    runat   = 服务器    ID   = 检查    OnClick   =  check_Click   文字  = 检查      /  < span class =code-keyword>>  
 
 
 <   / div  >  

Codebehind是

  protected   void  check_Click（对象发​​件人，EventArgs e）
 {
 
  var  employee = _ service.GetAllEmployee（）; 
 
 txtCount.Text = employee.Count（）。ToString（）; 
 
} 
 

解决方案

您是否调试过代码？检查代码流是否到达click事件处理程序？

如果代码流到达click handler，请检查_service.GetAllEmployee（）;

i am new in c# sql,i want to show total number records that has been entered in to the database.
here is the code

<label class="col-sm-3">
                    Count:
                </label>
                <div class="col-sm-2">
                    <asp:TextBox runat="server" ID="txtCount" AutoPostBack="true"></asp:TextBox>
                    <asp:Button runat="server" ID="check" OnClick="check_Click" Text="Check"  />


                </div>

Codebehind is

protected void check_Click(object sender, EventArgs e)
       {

               var employee = _service.GetAllEmployee();

               txtCount.Text = employee.Count().ToString();

       }

解决方案

Did you debug the code ? Check whether the code flow reaches the click event handler?
If code flow reaches click handler ,check what is the value returned by _service.GetAllEmployee();
