推荐答案

对于Panel的DefaultButton工作你需要让Panel成为焦点......在你的代码中，Panel是第一个（首先是它......）并且它没有任何DefaultButton ......

如果你想要该按钮是全局默认值，使用表单的DefaultButton属性...

For DefaultButton of Panel to work you have to have the Panel in focus... In your code the Panel in focus is the first (as it comes first...) and it has no DefaultButton whatsoever...
If you want the button be a global default, use DefaultButton property of the form...

向父面板添加默认按钮。

Add a default button to the parent panel.

<asp:Panel ID="someOuterPanel" runat="server" DefaultButton="btn_Process">
   <asp:TextBox id="someTextBoxOutsideInnerButtonPanel" runat="server" />
      ... other buttons and stuff...
   <asp:Panel ID="pnl_BeneficaryDetails" runat="server" DefaultButton="btn_Process" > 
         <asp:ImageButton runat="server" ID="btn_Process" OnClick="btn_Process_Click" Visible="false" ImageUrl="~/image/process.png" ToolTip="Process Payment" />
