Don't use a class to generate a gridview

[Zhongming]

    I am new to the telerik silverlight controls.  I want to use radgridview to do something.  After I read the document, I found that if you want to generate a gridview with some data, you need use a C# class to do that. But on my side, I want to generate the gridview by my own hand, because the gridview will have different columns(different head names, different amount of columns). I can't use a class to implement this. Can telerik gridview do this? And how can it do this?
