Any possibility to avoid cache in asp.net

You mean apart from turning it off ? Most people ask this because they've written bad security code, and need to fix it. Is that your problem ?

In my page While the landingpage was load, the videos are displayed. Then i move to another page name video.aspx and upload one new video.when i move to the landing page That currently inserted video is not reflected in the landing page. I think because of cache problem.Any solution?

Remove Output Cache for One Page

HttpResponse.RemoveOutputCacheItem("/foldername/CacheForever.aspx");

Add Key Dependency to Page

Response.AddCacheItemDependency("clearcachekey");

Means we placed a dependance on smallkey. Now place this in global.aspx

protected void Application_Start(Object sender, EventArgs e)
{
HttpContext.Current.Cache.Insert("clearcachekey", DateTime.Now, null,
System.DateTime.MaxValue, System.TimeSpan.Zero,
System.Web.Caching.CacheItemPriority.NotRemovable,
null);
}

or add this in pageload on which you want to remove cache :

HttpContext.Current.Cache.Insert("clearcachekey", DateTime.Now, null,
System.DateTime.MaxValue, System.TimeSpan.Zero,
System.Web.Caching.CacheItemPriority.NotRemovable,
null);

:thumbsup:

Yes it is because of caching. Browsers cache content depending on the URL. So when video is uploaded, change the URL of the video so that browser will load the latest content. To do this, add a dummy time stamp to the video link. Something like video.aspx?videoid=10&timestamp=somerandomvalue since the random value will be different each time, browser will be forced to load a latest version for each request. :)
