I am converting Infragistics 2010 v2 CLR3.5 to Infragistics 2014 v2 using 4.5 CLR using Visual Studio 2013 Professional Update 4. I am getting following error while building the project. Please reply immediately..........

Below is the code of "UltraWebTab", I would like to know the new properties of "WebTab" which I was unable to found....Plzz reply POINT-WISE ...after my points which would be easier for me to implement.

1. Scroll Buttons: I am not able to see <PressedStyle BackColor="#E1EDFF"> and <HoverStyle BackColor="LightSteelBlue"> ... please let me know alternative so that my functionality don't get disturbed.
2. ClientEvents: What is the same alternative property of "BeforeSelectedTabChange" as this one this one is not valid attribute coming while upgrading  <ClientEvents  BeforeSelectedTabChange="contentTab_BeforeSelectedTabChange"></ClientEvents>
3. Under "Tabs" - Tab Key=1 : Under <Tabs>, <igtab:Tab Key="1"> it is not taking "Tab", what should I use?? *********This is really very important as I am using total 5 different Tabs like Tab Key=2, Tab Key=3, Tab Key=4, Tab Key=5..............like how this is one Tab Key=1 shown in below code such different Tab key till 5 being used so code is too long. Below is just one example I pasted here for your reference......
4. ContentTemplate: <ContentTemplate> element ContentTemplate is not supported is coming but it is a huge functionality so give the alternative of this.
