Hi Michael,

That could happens because ASP.NET still cache the page which loaded from iFrame. To have a fresh data after first load then you need to disable response page in your page that contains WebGrid. You can put these codes on Page_Load event of yourwebgrid.aspx:

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetValidUntilExpires(false);

Hope this helps.

Hi Dicky

Thanks, it works.

You can try to refresh WebGrid on client side using OnPaneItemClick event provided in WebExplorerPane. So everytime user click on it you can find the WebGrid object and refresh it manually.

But I'm affraid this can cause some problems because you are using IFrame content mode which is it will make you difficult to find WebGrid Object, and also I think it will cause a problem if IFrame still loading the content while you trying to find WebGrid object. So I propose you to use SetCacheability as mentioned before.
