1.按回车键不提交数据。 

if (window.event.keyCode == 13)

{

    event.returnValue=false;

    event.cancel = true;

}

2.在文件框中按回车键触发提交事件

TextBox1.Attributes.Add("onkeydown", "if(event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('"+Button1.UniqueID+"').click();return false;}} else {return true}; ");

3.ASP.NET2.0中网页打开设置一个默认的按钮焦点

<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>
