We had a legacy .NET web-service that uses WSE 3.0. We are the service provider and we have an intermediate authentication server as well as the consumer. We had intermittent mysterious socket time out exceptions.
A thorough network snoop was conducted across 4 network teams (we span across 2 intranet and 2 WAN domains). Everything was healthy with <10ms latency between hops.
It was puzzling and a stroke of genius came by and we decided to check the inputtrace.webinfo and outputtrace.webinfo (default logging configs). Nothing special about it except for the size. Monthly scheduled jobs archival results in file size in excess of 600mb. Some team members had argued that logging mechanism should be asynchronous and should not have any influence on the response SOAP. There's no harm trying to flush out the logs and archive and do a re-test. Sure enough everything was back to < 0.5s
Our corrective action was to increase the frequency of the archival from monthly to weekly.

Gridview grouping
I've worked with SPGridView quite a bit lately and know that grouping is achievable, i thought that Gridview being the superclass of SPGridview, it should support grouping as well. I was wrong. My girlfriend had a requirement to group a set of data based on their type. A mock set of the data involved:
Product A - Type A
Product B - Type A
Product C - Type B
Product D -Type B
Product E - Type C
Product F - Type D
My first move was to take a look at the DAL (Data access layer) to see how the objects are related, in order for me to plan on grouping it. They are returned as generic dataset, so i had to create some simple POCO (Plain Old C# Objects), i prefer to work with strongly-typed grids :)
After retrieving the the data, i've modified the DAL to return an IList of the POCO instead of DS.
With the data retrieval and formatting done, all i have to do now is to bind it to a gridview and set the group by option. A little googling, i found a custom gridview which allow grouping:
Product A - Type A
Product B - Type A
Product C - Type B
Product D -Type B
Product E - Type C
Product F - Type D

ZNetControls
Read a little on the page and from the author's documentation, it seem simple enough.

- I created an ObjectDataSource that hooks up with the DAL GetAllBindableObjects() as the selectmethod.
- Added the library (ZNetControls) into my VS and added the ZNetGridview into the page
- Added the grouping type: DataKeyNames="Category"
Ran the page and i get this:
Pretty easy to implement :)
