I started a new Astronomy Calculator that needed a date inputted. So, I created an ASP.NET page and inserted the calendar control. It looked like a good solution but since this was for astronomical calculations, someone might want to select a year far in the past. Scrolling was way too painful.
So, I did a web search and found an ASP.NET AJAX extender that would link a calendar control to a textbox. I tried out the samples and thought this would be a better way. So, I started to read about the installation process. I tried to use the NuGet Package Manager but it didn’t work. I thought it might be because I was using the Express version of Visual Studio. I next tried to manually install but when I ran the code, I received many errors. I also found this method to install from the Package Manager Console.
Then I remember having had issues if Visual Web Developer wasn’t run as an admin on Windows 7. I tried that and was able to install the package.
Finally, I reviewed how to Display a Simple Popup Calendar sample. The key step I missed was to add the ToolkitScriptManager control. Everything started working great.
