网格不会每次都刷新。我可以整个窗口刷新吗？

如何在RELOADS .aspx页面创建一个Javascript方法，以便在其他现有方法之一中调用。网格不会每次都刷新。我可以整个窗口刷新吗？

另外，我在mygrid.refresh（）之后发出警报;声明，我可以看到警报，但由于某种原因，不是新上传的文件，直到我还是F5。这就像刷新网格没有做任何事情。 – Scott 2010-09-08 14:52:40

想通了。将RefreshGrid（）更改为此。

function RefreshGrid(result, data) { 
       window.location.reload(); 
       if (data.responseText.length > 0) { 
        var obj = eval('(' + data.responseText + ')'); 
        if (obj.Result == false) { 
         Global.alertError(obj.UserMessage, obj.ExceptionID); 
        } 
        else { 
         Global.getComponent('txtDescription').setValue(''); 
        } 
       } 
      }

应该在GridView（Check Ext Docs）上调用refresh（）函数。所以，如果 “mygrid” 是你的GridPanel，然后调用它是这样的：

mygrid.getView().refresh();

获取此错误。 mygrid.getView不是函数 – Scott 2010-09-08 15:40:25

如果“mygrid”是一个GridPanel，那么应该有getView（）方法。在控制台中检查mygrid - 是否有任何getView（）方法。在GridView API中检查refresh（）方法 - http://dev.sencha.com/deploy/dev/docs/?class=Ext.grid.GridView – Swar 2010-09-08 16:19:15

我相信弹出的窗口是ExtJS窗口，但我认为父页面上的网格只是一个常规的ASP.NET网格。 mygrid.refresh（）的代码;没有错误，但没有工作。我只想要一种方法来从ExtJS弹出窗口中硬刷新父.aspx页面。 – Scott 2010-09-08 17:41:39

网格不会每次都刷新。我可以整个窗口刷新吗？
