如何实现按回车键提交webpart?

[commandolee]

对于很多表单，在提交的时候如果能通过按回车来postback是很方便的。但是由于webpart与webform的机制不同，似乎无法直接在webpart中设置默认按钮来提交。

有没有人成功地实现过在webpart中将回车键按下的事件提交呢，谢谢

使用js捕捉键盘的enter事件即可。

我找到了更好的解决办法：

"ASP.NET 2.0 makes this problems easier and introduce a concept of a "default button". New defaultbutton attribute can be used with <form> or <asp:panel> control. What button will be "clicked" depends of where actually cursor is and what button is chosen as a default button for form or a panel.

Here is sample HTML code that contains one form and one panel control:"

<form defaultbutton="button1" runat="server">
<asp:textbox id="textbox1" runat="server"/>
<asp:textbox id="textbox2" runat="server"/>
<asp:button id="button1" text="Button1" runat="server"/>
<asp:panel defaultbutton="button2" runat="server">
<asp:textbox id="textbox3" runat="server"/>
<asp:button id="button2" runat="server"/>
</asp:panel>
</form>
