Basically you need to setup the following performance counters in windows:

  • Total number of objects added
  • Total object discards
  • Cache hit count
  • Cache hit ratio

<safemode callstack="true" maxcontrols="200">

Then turn the customErrors mode to OFF. This should help you determine the problem.

Whew...its been a long week and its only Thursday. This years conference was much the same as last years with the exception of being held in various portions of the Mandalay Bay convention center as opposed to on one floor. This made for lots and lots and lots and lots of walking. But I'm still young (yes i am) so it makes for good excercise to walk off all the food they shovel in your mouth.

Most of the sessions I attended were really good with the exception of a couple. I wouldn't blame the speakers because these problems were mostly due to technical issues like the computers not working, the projectors broken or feedback in the presenters microphone sort of thing. All in all there were some great things presented this week.

Some of the sessions that really stuck out were:

Kimberly Tripp - Index Internals and Usage
This was a great session that talked about thins like SQL Server Statistics, Query Optimization, Types of indexes, diminishing returns on performance, etc. Of all the session I think this one stood out the most and because it is probably the most relevant for me right now being one of the "SQL Server DBA" for my company (Christie Digital). I say it that way because its a committee based DBA :)

Rick Strahl - Using WCF for JSON and REST Services with ASP.Net

Great session....last one of the conference for me so it really sticks out but essentially this covers the next gen replacement for ASMX or first gen webservices in the .NET Framework.

John Papa - Practical Strategies with the Entity Framework

For me this was an introduction to the Entity Framework that was released in VS 2008 SP1. John did a great job of quickly introducing the technology and getting on to the meat and potatoes of what we were there to discuss. There was a good discussion on how to use the IDE to build the data mappings and what happens after you make changes to the backend server, which coinceidently can be any data source...not just SQL as Linq to SQL supports.

Things I would change...(and only because its my blog and I can say whatever I want!!!)

...the time between sessions was ridiculous...one hour or in some cases and hour and a half is just way too long. They could have added an extra session or two to the day. I realize they want you in the expo hall but they could have extended the day to facilitate that or leave it open all day and then some people may skip a couple of sessions here and there to go and see what the vendors are offering. this was my gripe last year and its my gripe this year. Its probably going to be the thing that keeps me from going to this in the future.

...provide video or podcasts of the sessions so we can take in the whole conference...even the sessions we didn't get to go to. I see there point about this being intellectual property and the speakers are consultants and this is their livelyhood but I mean if they are willing to teach this at a conference...and we pay to see it...shouldn't we be entitled to review this information after the fact? Maybe they will supply it on their site (i heard they were recording the sessions this year).

...ease up on the food. Damn, there was too much...I ate too much...I felt stuffed the whole time...I guess this is really my fault! Okay dont change that :)

Using a SharePoint Data View Drop down list This is the following syntax used to connect to an SPDatasource

< runat="server" id="dvddl{$Pos}" fieldname="HRRecruitRequisition" datasourceid="Requisitions2" datatextfield="Title" datavaluefield="ID" bind="{ddwrt:DataBind('i',concat('dvddl', $Pos), 'SelectedValue', 'SelectedIndexChanged', 'ID', ddwrt:EscapeDelims(string(@ID)), '@HRRecruitRequisition')}" appenddatabounditems="True" width="250px">

The meat and potatoes of this is in the __designer:Bind and FieldName attiributes. Obviously the DataSourceID needs to match the ID of the SPDataSource you are looking o display in the dropdown.
