根据视口更改边界字段可见状态

我有一个带有许多边界字段的网格视图。我正在尝试使某些边界字段可见或不可见，具体取决于屏幕的宽度。我到处都看过，并且尝试了 visible="<%=javascript:widthFunction()%>" ，

        function widthFunction(){
            viewportWidth = window.innerWidth;
            if(viewportWidth > "500")
                return true;
            else {return false;}

显然这不起作用。我尝试将类似的代码放在我的代码后面，但这需要 DataBind 的东西，这是行不通的，因为

解析器错误消息：数据绑定表达式仅在具有以下属性的对象上受支持数据绑定事件。 System.Web.UI.WebControls.BoundField 没有 DataBinding 事件。

如何解决这个问题？

原文

I have a gridview with a number of boundfields. I'm trying to make it so that some boundfields are visible or invisible depending on the width of the screen. I've looked everywhere, and i tried visible="<%=javascript:widthFunction()%>" where

        function widthFunction(){
            viewportWidth = window.innerWidth;
            if(viewportWidth > "500")
                return true;
            else {return false;}

Clearly that's not working. I tried putting similar code in my code behind, but that requires the DataBind thing, which that won't work because

Parser Error Message: Databinding expressions are only supported on objects that have
a DataBinding event. System.Web.UI.WebControls.BoundField does not have a DataBinding
event.

How can this be solved?
