how to set duration programmatically

[amirjelo]

i want to change the duration of DonutOutputCache attribute from database record.

so i just write a custom outputcache which is childof DonutOutputCacheAttribute :
public class CmsOutputCache : DonutOutputCacheAttribute
{
public CmsOutputCache()
{
var setting = SettingBL.GetAdvancedSetting();
this.Duration = setting.TimeCache * 15;

    }
}

and use it like this :
[ChildActionOnly]
[CmsOutputCache]
public ActionResult HeaderSlider(){}

but the behavior of caching not working now!
how to set duration?

Can you upload a test project so that I can reproduce the issue or tell you what is wrong ?

@amir-yeketaz We needed something similar, and it worked for us. So it should be possible.
