我在上面表单的 OnClick 事件中插入了调试点，但是一旦在调试模式下运行此应用程序并单击btnShow"按钮，此应用程序就不会指向此调试点.我的方法有什么问题?
I inserted debug point inside the OnClick event of above form, but Once run this application in debug mode and click "btnShow" button this application does not point to this debug point. whats wrong with my approach ?
推荐答案
你还没有给按钮附加事件处理程序，添加一个:-
You have not attached the event handler to the button, add one:-
<asp:Button ID="btnShow" runat="server" Text="Button" Width="56px"
OnClick="btnShow_Click" />
或者，您也可以像这样以编程方式附加事件:-
Alternatively, you can also attach the event programmatically like this:-
protected void Page_Load(object sender, EventArgs e)
{
btnShow.Click += btnShow_Click;
}
