Animate a GridView row using the AJAX Control Toolkit from client code
I've run across a few situations in which I wanted to animate a certain row in a GridView as a result of some client action.A0 The reason that this is a little tricky is that the AJAX Control Toolkit's Animation Extender needs to act on a certain Target Control (identified of course by the TargetControlID) and you can't point the target control as a specific grid view row (not that you would even want to).

Changing the ASP.NET AJAX Control Toolkit Calendar display mode
The ASP.NET AJAX Control Toolkit's Calendar (Click Here To See The CalendarExtender Control In Action) is a very nice control that allows you implement a client side dynamic calendar for date-picking functionality. One interesting feature is the ability to change the calendar from the default "days" mode (shows the days in one month) to "months" mode (showing all of the months in the current year) by clicking on the calendar title. Another click on the title will change the calendar into "years" mode, which shows 12 years at a time.

Sending Email Attachments with ‘Friendly’ Names in .NET 2.0
I can across a problem today where I had to attach a PDF file that is stored on a network share to an outgoing email using ASP.NET 2.0. This is pretty simple to do, except in my case the PDF filename on the share has an obfuscated name while its original name (file.pdf) is stored in a database lookup table. Looking at the System.Net.Mail.Attachment constructors, you'll see that three take a string filename and three take a System.IO.Stream object to represent the file. The string filename constructors do not possess the ability (as far as I could see) to give the attached file a "friendly name", although one of the Stream constructors does. So what I ended up doing was opening the file with a non-locking FileStream object and then passing it to the mail attachment object, careful to close the stream when I was done. Pretty simple, but I couldn't find any sources using this method so I thought I'd write it down here (minus error handling code for clarity):

Dynamically Render A Web User Control
I recently ran into a situation where I wanted to render the contents of a user control either directly to the current HTML stream or to a file format like MS Word. Fortunately .NET has the 'LoadControl' function that takes the virtual path of a User Control and returns a Control object. In order to get the rendered output of a user control into an HTML32TextWriter, you can use the following code:
