Some of you might have recognised that we are using a customised version of the SubText blogging engine for these blogs. Recently, I've made some changes to support additional feeds and I thought I'd share them with you.

Microsoft have released significant parts of the .NET framework source code for developers using Visual Studio 2008. In case you've not been following the releases, this blog post includes links to configuration and hotfix resources.

I've been playing around a bit with the idea of integrating Windows Workflow Foundation into custom web server controls. I've had some success but also hit something of a wall. If you have any experience with any of these issues, I'd love to hear from you.

I've recently hit an issue where some custom controls have been generating exceptions when unpublished pages exist in an EPiServer site. In these cases, the relevant (required) properties have null values.

When you are using the (very helpful) UpdatePanel, the browser doesn't keep track of the asynchronous postbacks. This means that when the user clicks the back button in the browser, they go to the navigation prior to the last full postback.

How can you resolve this?

This should be easy, but easy it is not. I'm using an EPiServer 4.6 site for this one, so things might've improved in more recent versions, but this caused me a lot of trial and error. I hope this post saves you the hassle...

Using EPiServer, you may use the FindPagesWithCriteria method to retrieve a list of pages based on certain properties, but the helpfully enumerated conditions may be confusing. After all, with a binary inequality operator it is quite important to know the order of the expressions...

I've been importing a live EPiServer site into a development environment for further work. Normally, this works without problem, but this time I've been getting a POST error, but nothing informative. What's happening?

Suppose that you have found the perfect control that works with almost all the browsers you need to support, but suppose it has breaking functionality for a particular browser. How can you solve this problem?

EPiServer does not exclude pages outside of publishing schedules when retrieved using the FindPagesWithCriteria method. Read more to workaround this issue.
