asp.net - 设置默认按钮输入 - 母版页

Question

大家好，我有下一个问题。当我按 Enter 时，我必须将一个按钮设置为默认按钮。我可以在表单中使用 DefaultButton，因为现在我的所有页面都继承自母版页，并且我有来自母版页的内容，但这是行不通的。有人可以给我任何替代方案来解决这个问题。谢谢

根据 Enter Key - Default Submit Button :

ASP.NET 2.0 introduces a wonderful work around for this. By simply specifying the "defaultbutton" property to the ID of the , whose event you want to fire, your job is done.

The defaultbutton property can be specified at the Form level in the form tag as well as at panel level in the definition tag. The form level setting is overridden when specified at the panel level, for those controls that are inside the panel.

Also, the Event Handler for the specified button, fires thereby simulating a true submit button functionality.

像这样

<form id="form1" runat="server" defaultbutton="Button1">
<div>
<asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Click" />
</div>

或者你可以通过

Page.Form.DefaultButton = crtlLoginUserLogin.FindControl("LoginButton").UniqueID

或者只是

Page.Form.DefaultButton = LoginButton.UniqueID

这会起作用。
