Change background color

Capture

I would like to get access to the background color in the attached picture. I would like to be able to change it per instance of a DataGrid. Can you tell me how I might do that?

Thanks

Use your browser developer tools inspector to check what CSS is applied. Later you can apply custom rules using the id attribute and desired class.

I see that it is rz-group-header. I can change the background color for all uses of the class. But I don't know how to use custom rules and the id attribute as you suggest. I understand this is outside of your product; but can you point me to an example? Very much appreciated it if you can.

Thanks
