前台:
function GetFocus()
{
    if(event.keyCode==13)
    {
        document.getElementById("Button1").click();
        return false;
    }
}

后台:
TextBox1.Attributes.Add("onkeydown","return GetFocus();");

或者：
<SCRIPT LANGUAGE="javascript">
    function SubmitKeyClick(button)
    {
        if (event.keyCode == 13)
        {
            if(event.srcElement.id=="tbInput")
            {
                event.keyCode=9;
                event.returnValue = false;
                document.all[button].click();
            }
        }
    }
// -->
</SCRIPT>

1、将页面上所有回车事件都绑定到一个按钮上
<HEAD>
<script language="javascript">
function EnterTextBox()
{
   if(event.keyCode == 13 && document.all["TextBox1"].value != "")
   {
    event.keyCode = 9;
    event.returnValue = false;
    document.all["Button1"].click();
   }
}
</script>
</HEAD>
<body onkeypress="return EnterTextBox()">

2.不同的TextBox绑定不同的Button
<HEAD>
<script language="javascript">
function EnterTextBox(button)
{
   if(event.keyCode == 13)
   {
    event.keyCode = 9;
    event.returnValue = false;
    document.all[button].click();
   }
}
</script>
</HEAD>

在对应的cs文件中
//绑定TextBox回车事件
TextBoxPortOfDestination.Attributes.Add("onkeypress", "EnterTextBox('ButtonChoose')");
TextBoxItemName.Attributes.Add("onkeypress","EnterTextBox('ButtonAdd')");
TextBoxCost_PX.Attributes.Add("onkeypress","EnterTextBox('ButtonAdd')");
TextBoxCost_1X20.Attributes.Add("onkeypress","EnterTextBox('ButtonAdd')");

asp.net的TextBox回车触发事件

一

//直接在js中写

function EnterTextBox()
{

if(event.keyCode == 13 && document.all["TextBox1"].value != "")
{

event.keyCode = 9;

event.returnValue = false;

document.all["TextBox1"].click();

}

</script>

//此处TextBox1为页面上TextBox的ID

二.
<script language="javascript">

function EnterTextBox(button)
{

if(event.keyCode == 13 && document.all["TextBox1"].value != "")
{

event.keyCode = 9;

event.returnValue = false;

document.all[button].click();

}

</script>

在PageLoad事件里

TextBox1.Attribute.add("onkeypress","EnterTextBox('Button1')");
