ListView: Using DisplayIndex when Paging

By Winston ⋅ December 11, 2008 ⋅ Post a comment

Just learned that you need to use a row’s DisplayIndex rather than its DataItemIndex when retrieving its DataKey value.  Otherwise, stuff is not going to work with paging.
Not obvious.  But I guess it makes sense.  
DataItemIndex is the index of the row within the overall data set.  DisplayIndex is the index of the row within [...]

BindOnPreRender Control

By Winston ⋅ November 13, 2008 ⋅ Post a comment

One useful little control we wrote for ASP.NET is our BindOnPreRender control.  It simply calls DataBind() on itself at PreRender.
Its utility may not be obvious.  This is sort of related to my post on WebForms DataBinding.  Binding is better.  It lets us bind properties to objects in our markup, which helps reduce code-behind.  I’m not [...]

URL Rewriting and ASP.NET Browsers - is a beating

By Winston ⋅ October 16, 2008 ⋅ Post a comment

We’re lucky we have an error handler in our web app that emails us about every single unhandled error, or we wouldn’t know about this one at all.

ASP.NET WebForms: As *Component Frameworks* Go, It’s Pretty Good

By Winston ⋅ February 10, 2008 ⋅ One comment

I just want to talk for a moment about the things that are good about WebForms.
WebForms is a Component Framework
First of all, we have to acknowledge that WebForms is a component framework.  Many people who are critical about ASP.NET WebForms are actually criticizing the whole component approach to web development.  Others criticize component frameworks because [...]

On the WebForms vs MVC Debate

By Winston ⋅ February 6, 2008 ⋅ One comment

Actually, it’s not a debate — it’s incredibly one-sided, which is the reason that I’m going to write a few blog posts to say:
Webforms doesn’t totally suck.
We recently chose it over ASP.NET MVC for a reason.
Part of the reason is that I and my team have had PLENTY of experience with MVC in Java and [...]
