                </table>
            </td>
        </tr>
   </table>
          </form>

但这仅在我单击某处（将焦点从搜索控件上移开）然后按回车时才有效

请建议

您可以将控件放在 a 中asp:panel并将其设置为默认按钮。

<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 时要单击的默认按钮？只需将以下行添加到页面的 Load 事件中，将“btnSearch”替换为按钮的名称。它使用了一个名为 RegisterHiddenField 的隐藏 Page 方法，效果非常好：

Page.RegisterHiddenField("__EVENTTARGET", "btnSearch")

来源：-默认按钮

将此脚本放在脚本管理器下方：

<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>

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
