This is a living list of DevExpress videos that I've personally found useful and so are probably good for other DevExpress beginners.

SOPA and the NDAA

-
During the Internet blackout today against SOPA, I was complaining on VoiceOfTheDBA that I wish we could get a blackout on the recent "indefinite detention of US citizens" fiasco. I said: Unfortunately (as you know) we have bigger issues. I’d love to see a blackout for basic liberty:   http://www.washingtonpost.com/opinions/is-the-united-states-still-the-land-of-the-free/2012/01/04/gIQAvcD1wP_story.html   http://www.huffingtonpost.com/2011/11/29/senate-votes-to-let-military-detain-americans-indefinitely_n_1119473.html   http://abcnews.go.com/blogs/politics/2011/12/with-reservations-obama-signs-act-to-allow-detention-of-citizens/ But now I've read the actual final section of the law under question, and couldn't figure out what the big deal is: http://thomas.loc.gov/cgi-bin/cpquery/?&dbname=cp112&sid=cp112MdQpb&refer=&r_n=hr329p1.112&item=&&&sel=TOC_1073854& Upon further research, I see that mostly the NDAA refused to clarify our sta...

For years now in DevExpress ASPxGridView's I have been handling this in the HtmlRowCreated event. And I have been doing it wrong. Before: protected void gridGiftCodes_HtmlRowCreated ( object sender, DevExpress.Web.ASPxGridViewTableRowEventArgs e) { if (e.RowType == GridViewRowType.Data){ int commandColumnIndex = - 1 ; //Find the command column commandColumnIndex = e.Row.Cells.Count- 1 ; //assume it's the last visible colum //Get the command cell for this row GridViewTableCommandCell cell = e.Row.Cells[commandColumnIndex] as Gri...

Why I still don't use Entity Framework for small-to-medium business applications

-
This post is really about the cons of Entity Framework. I know, I know, it's sacrilege to not be in love with EF and using it everywhere, and I feel I am taking some professional risk expressing these thoughts. But I actually find Entity Framework to be problematic in many ways, both technologically and philosophically, and I am frustrated that it is now the "standard" way to do data access in Microsoft land. To be the standard implies "generally suitable for most applications", which in my experience, Entity Framework is not.
