RadControls for WPF are a third-party controls and they are built from scratch and have nothing to do with their standard counterparts. This is why our default theme is not a "custom" look but rather the expected one. The main reason for the differences with the standard one is based mainly on clients' requests - most of our clients want to get away from the standard look and feel. This is why we offer 9 built-in themes - all based on clients' feedback.
Also, I hope you will agree with me that our controls should blend with each other and not with all other themes available from standard controls or competitive vendors. Given the fact that sometimes our clients want to use controls from different vendors, we have provided them the possibility to fully customize our controls so they can achieve the best result for them.
If you have any specific issues while creating your custom theme, please let me now. Our support officers will do their best to assist you.
