您可以将控件放在asp:panel并设置它的默认按钮。
<asp:Panel ID="p" runat="server" DefaultButton="myButton">
<%-- Text boxes here --%>
<%-- drop down here --%>
.....
<asp:Button ID="myButton" runat="server" />
</asp:Panel>

设置用户按Enter键时单击的默认按钮？ 只需将以下行添加到页面的Load事件中，将“btnSearch”替换为按钮名称即可。 它使用一个名为RegisterHiddenField的隐藏Page方法，并且工作得非常出色：
Page.RegisterHiddenField("__EVENTTARGET", "btnSearch")
来源： - 默认按钮

尝试使用Button及其UseSubmitBehavior
<asp:Button ID="btnSearch" runat="server" Width="125" Height="45" UseSubmitBehavior="true" />
而不是图像按钮。
您可以使用css轻松设置按钮的背景图像。 所以不要使用图像按钮

将此脚本放在scriptmanager下面：
<script type="text/javascript">
var $p = Telerik.Web.UI.RadComboBox.prototype;
var keyDownHandler = $p._onKeyDown;
$p._onKeyDown = function (e) {
var oReturnValue = e.returnValue;
var oPreventDefault = e.preventDefault;
var keyCode = e.keyCode || e.which;
if (keyCode === 13)
e.preventDefault = null;
keyDownHandler.call(this, e);
if (keyCode === 13) {
e.returnValue = oReturnValue;
e.preventDefault = oPreventDefault;
}
};
</script>
