斷行符號鍵在ASP.NET2.0中的應用

1.按斷行符號鍵不提交資料。 
if (window.event.keyCode == 13)
{
    event.returnValue=false;
    event.cancel = true;
}
2.在檔案框中按斷行符號鍵觸發提交事件
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中網頁開啟設定一個預設的按鈕焦點
<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>
