Peter’s Date Package is available as a web-based download. Accompanying the installer file, which is about 1.5MB, should be an email detailing your license key and user ID. Running the PDPInstaller.msi installer file will set up Peter’s Date Package on your system. Before you can use the controls, you need to copy the license file to the appropriate folder and reference the license key in your application’s Application_Start method. Both of these steps are detailed in the User's Guide PDF. The User's Guide is quite impressive, weighing in at 190 pages and covering nearly every typical scenario and question that you will have as you get going with these controls.
These controls offer several varieties of licensing, to fit the needs of different organizations. You will find them detailed here: http://peterblum.com/DateControls/Commercial.aspx. At a base price of $50 per server, the controls are a steal, because developing any one of them with comparable quality and attention to detail would take several days at least (more likely weeks or months), and most .NET developers skilled at building custom controls make more than $50 per hour.
Installation and licensing setup is covered in the User's Guide on pages 16–18. Basically all you need to do is drop the .lic file you received via email into the licenses directory under your InetPub\wwwroot\aspnet_client directory. Then, in your Application_Start method, add the following line:
PeterBlum.PetersDatePackage.Globals.Licensing="[your license key]";
Once these simple steps have been completed, it’s easy to use the controls on your ASP.NET pages. In VS.NET, the controls have nice design-time views, and provide a wealth of properties that enable you to customize their behavior and appearance. If you want to use the default look of the controls, you will need to add the following line to any page on which you use the controls:
<link href="/aspnet_client/PetersDatePackage/Appearance/Stylesheet1.css" type="text/css" rel="stylesheet" />
