Hi Rahul,
Thanks for your interest in Syncfusion products and i apologize for the delay in getting back to you.
You can achieve your requirement by inheriting the Office2007Form class to the normal Form. For more information i have inlude the Documentation link and a simple sample as follows.
Note : If you are using Windows vista or Windows 7 OS, Please ensure that the Forms 'ApplyAeroTheme' and 'UseOffice2007SchemeBackColor' is disabled and enabled respectively. Therefore the changed color scheme will have their effect on the Forms' boarder and backColor.
