Set Enum Value with reflection .Net1.1 and .Net2.0

Asp.Net Performance: Use explicit cast instead of using Eval
(Indexed 2006-11-23):
I have come through lots of examples in the web using DataBinder.Eval but if we go and see whats happening under the hood, we will find Eval uses reflection to evaluate argument passed. But explicit casting can reduce the cost of reflection. Imagine if there is 30 rows and each row has 6 Eval calls. So there will be calls to Eval 180 times. And we should take this pretty seriously. So you must be thinking what to do. Hey we can simply do something like this and improve significant performance. ...(truncated)...

Cache Invalidation for Dynamic pages in Asp.net 2.0
(Indexed 2006-11-16):
Asp.net 2.0 supports database cache dependencies. So changes in the Tables data can be notified and cache can expire. This is a very handy feature. Here is how we can do this this means the cached page expires in 2 hours but also depends on database table. Any changes on the database table data will also invalidate the cache.
