Hi Alex,
These controls are used throughout mojoPortal. A small sampling of examples is listed below.
DatePickerControl (mojoPortal.Web.Controls.DatePickerControl)
mojoButton (mojoPortal.Web.UI.mojoButton)
mojoGridView (mojoPortal.Web.Controls.mojoGridView)
Properties for these controls can be found by clicking the links next to the titles above.
I hope this helps,
Joe
