Hi Satish
If you do not want the themed look all you need to do is ensure that the ThemesEnabled property of the DateTimePickerAdv control is set to false as demonstrated in
this screenshot. If you want the themed look you need to set the FlatStyle property of the ComboBoxAdv control to System and enable themes for the DateTimePickerAdv (Some fixes were made post version 2.0.5.1 in the DateTimePickerAdv to address this so open a Direct-Trac incident if you want to get the latest patch. This fix is part of the 2.0.6.x version which will be available for download soon).
You can play around with the settings for both the controls to get the desired look and feel.
Regards
Arun
