Ok, it might not be that awesome, but I have come across a few items that (if you are an Asp.net developer) you'll find useful (or at least potentially useful).
1) Asp.Net Resource Kit - Contains a bunch of 3rd party components: ComponentOne Studio Enterprise (without subscription), IP*Works! CC ICharge, Infragistics NetAdvantage ASP.NET grid, Sax.net Security, and telerik's r.a.d.rotator and r.a.d.spell.
2) VB.Net Resource Kit - This includes some real 3rd party components: ComponentOne Studio Enterprise (again without a subscription), and Infragistics UltraWebNavigator and UltraWinTree Controls [it also includes Dundas Chart for Winforms and the Sax.net Communications library]. It also includes some nice samples, articles, and other goodies.
3) eXcentrics World Controls - Has 11 ASP.Net controls available: Accordion Panel, Bread Crumb Trail, Calendar Popup, Collapsible Panel, Empty DataGrid, Faq Repeater, Masked TextBox, Multi-Text List Controls, Numeric Box, Ordered Listbox, and TimePicker. Very well done! Source can be purchased (which is nice).
4) MetaBuilders Controls - (One of my favorites... I should send Andy Smith some money someday). This site has a huge collection of goodies (all with source code!). It has DataGrid Bound Columns (not that I'm a fan of the DataGrid, but you might be) - BoundBooleanColumn, BoundLookupColumn, and RowSelectorColumn. He also has a nice sized supply of ASP.Net components: CheckedListBox, ComboBox (complete with free form typing... doesn't work in Maxthon, BTW), ConfirmedButtons, CustomForm, DefaultButtons, DialogWindow, DualList, DynamicListbox, ExpandingButtons, ExpandingPanel, FileUpload, FirstFocus, GlobalRadioButton, ListLink, MasterPages, NestedRepeater, OneClick, ParsingContainer, QueryCall, RemoteWindow, ResizeMonitor, RollOverLink, RuntimeTemplate, ScrollingPanel (a favorite of mine), TypeValidators, and UpDown.
<gasping for air from long list /> As you may be able to guess a few of these are invisible controls that control some client-side aspect of the page. Andy has made a good mix (IMHO) of server-side and client-side code... It's not just client-side scriptlets that have been wrapped (they all work in the VS.Net designer!). My one complaint is that each control is a separate project (and therefore a separate DLL). I've tried to put them all in one DLL, but I get errors when I deploy the library...
(I figure none of this is news to most of you, but there are others who may discover my blog and need this stuff). I will write about some of the single control gems that I've found in the not-so distant future.
