Hello All;

I'm just beginning with the grid and I'm running across several events and techniques to perform data input validation.  No doubt people have UI behavior specifications to adhere to, which will dictate how validation is coded, so maybe people could mention that in their responses. (Assuming people have the inclination to respond to this question).  I ask because I'm looking at an application someone else wrote that uses about every possibility imaginable, which has resulted in some wildly convoluted code full of band aids to deal with the chaos.  Because I'm just learning this stuff, I'm leaning to a re-write but would like some learned advice before I begin.

 There's the BeforeCellUpdate and BeforeCellDeactivate pair, as seen at http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.aspx?ArticleID=1747   (I think I like this one)

or maybe BeforeRowUpdate and BeforeRowDeactivate

Or the BeforeExitEditMode, or _Error or do you like to go to the underlying ADO Datatable object and set up you data event handlers, like

new DataColumnChangeEventHandler
