解决方案 This article can give you a headstart:
http://aspdotnetcodebook.blogspot.nl/2008/03/how-to-create-shortcut-key-in-aspnet.html[^]
look this example
<body onkeypress="HotKeyClick();">
<asp:Button ID="Btn" runat="server" Text="Save" AccessKey="s" />
in js write this code
function HotKeyClick()
{
if(event.srcElement.type == 'text' || event.srcElement.type == 'textarea' || event.srcElement.type == 'select') return true;
var ArrButtons = document.getElementsByTagName('input');
for(var Count=0; Count < ArrButtons.length; Count++)
{
if(ArrButtons[Count].type == 'submit')
{
if(ArrButtons[Count].accessKey != null)
{
var keyChar = new String(String.fromCharCode(event.keyCode));
var acsChar = new String(ArrButtons[Count].accessKey);
if(keyChar.toUpperCase() == acsChar.toUpperCase())
{
if (ArrButtons[Count].disabled == false)
{
ArrButtons[Count].focus();
ArrButtons[Count].click();
break;
}
}
}
}
}
}
AccessKey is property to set shortcut key for controls.
<asp:Button AccessKey="S" ID="btnSubmit" runat="server">
