Having issue with page cache

Hi Kaushik,

In order to work with the cache from your code you can rely on Kentico CacheHelper class. Here are a few examples:

// Clear the output cache of a specific page
CacheHelper.ClearOutputCache(siteId, pageAlias, culture, true, true);

// Clear cache via dependencies
CacheHelper.TouchKey("someDependencyKeyOrDummyKey");

// Remove specific cache item by key
CacheHelper.Remove("cacheKey");

You can read more about cache keys, dependencies and dummy keys here in the documentation.

I have tried but not working.

Kaushik,

First thing I would do is to figure out what exactly gets cached?!

• Page output
• web part output
• data (query results)

Once you know this you'll have to clear cache for appropriate item.

Query result data. I have used querydatasource and then assign to repeater. Simple functionality is to generate the wishlist. But when i clear the cache then only it update the data.

So once you know what data gets cached and where just refer to Dmitry's answer and touch cache by the key to drop a cache just for that piece of data.

I do not understand the touchkey logic for datasource or page. i tried all ways but not deleted.

How do you add new item to wish list? - I believe you have some custom code (web part) to do that. So whenever you run the code to add/update/delete item to wish list you have to call the method, that will clear cached data.

Does it make sense?
