Let the user community start adding full walk-throughs, with working sample code that illustrate how to use the WebDataGrid to achieve certain tasks.
E.g. I would love to see a "How To: Resize WebDataGrid to use 100% width and height" or a "How To: Use an ObjectDataSource to Select, Insert, Update and Delete data."
The search does not always yield great results; I've found using google to search the forums is more effective, but having a "How To" library would be awesome.
They have been promising this for years.
Just how to find the API help in the documentation would do me for now!
