Changes are not visible - Cache problem?

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.

Hi Dicky

Thanks, it works.

It may be possible to refresh only the grid data instead of the whole page?

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.

Changes are not visible - Cache problem?

I use WebDesktopManager with IFrame Window (see attached file).

When I open the window for the first time I see the postback and the data is read from the DB.

After I have changed data I switch to another window. Then I switch back to the previous window (I see no postback). The changes are not visible! Only when I click refresh, the changes are visible again. Apparently, the data are cached at the first load.

How can I change this behavior? I always want to see the current data.

I have set AllowAutoDataCaching="False" and ViewStateStorage="None", but nothing happens.

Thanks for tips.

Regards

Michael
