Delegate CacheDataNotificationCallback

Defines a callback method for notifying applications when an item is updated in the Alachisoft.NCache.Client.Cache.

Assembly: Alachisoft.NCache.Client.dll
Syntax
public delegate void CacheDataNotificationCallback(string key, CacheEventArg cacheEventArgs);
Parameters
Type Name Description
System.String key

The cache key used to reference the item.

CacheEventArg cacheEventArgs

The cache event arguments.

Remarks

Since this handler is invoked every time an item is removed from the Alachisoft.NCache.Client.Cache, doing a lot of processing inside the handler might have an impact on the performance of the cache and cluster. It is therefore advisable to do minimal processing inside the handler.

Examples

The following example demonstrates how to use the CacheDataNotificationCallback class to notify an application when an item is updated to the application's Alachisoft.NCache.Client.Cache object. You could include this code in a code declaration block in the Web Forms page, or in a page code-behind file.

public static void OnCacheDataModification(string key, CacheEventArg args)
{
        //
}

protected void Application_Start(object sender, EventArgs e)
{
    try
    {
        ICache cache = CacheManager.GetCache("demoClusteredCache");
        CacheDataNotificationCallback dataNotificationCallback = new CacheDataNotificationCallback(OnCacheDataModification);
    }
    catch(Exception e)
    {
    }
}
