TtxtPetraDate specification and testing

requirements

• allow entering the date by digits only, eg. 311212 becomes 31-dec-2012
• allow entering = for todays date
• allow entering +3 for three days from today
• if an invalid date is entered, show a message. do not delete the input
• only throw a DateChanged event if there is a new valid date, or the date has been deleted

code

• there is a NUnit test
• there is a test application

events

DateChanged

• used in csharp\ICT\Petra\Client\MFinance\Gui\Gift\UC_GiftBatches-generated.Designer.cs, calling UpdateBatchPeriod

problems

• event TextChanged is only triggered on the screen, but not when the text property is changed???
• enter 30: messagebox, invalid date. but enter some text, no message box
• UK culture: can parse 20-MARCH-2012, but not 20-NOVEMBER-2012
