Question

我的aspx页面上有两个RadGrids，并使用一个搜索TextBox来搜索RadGrid中的项目。点击一个按钮，所选项目将被转移到其他网格。

问题是当我使用特定关键字搜索项目，然后从RadGrid中选择项目并单击按钮。不执行任何操作，并且在代码中，它显示没有选择任何数据项。然后，如果我再次从搜索列表中选择并单击按钮，它就可以正常工作。

   function requestStart(sender, args) {
        if (args.get_eventTarget().indexOf("ButtonPrint") > 0 
            ||
            args.get_eventTarget().indexOf("ButtonSelect") > 0
            )
            args.set_enableAjax(false);
    }

Answer 1

尝试将绑定源（我认为它是已过滤的网格）ajaxify到绑定目标（第二个网格）。

<telerik:AjaxSetting AjaxControlID="EnrollmentGrid">
    <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="EnrollListGrid" />
    </UpdatedControls>
</telerik:AjaxSetting>

如果有帮助，请告诉我。否则我真的需要一个更简单的代码工作版本......
