Hello Ladislav,

Moving a Field from one FieldGroup to another FieldGroup can be done only in code-behind by manually removing the Field instance from the Children collection of the first FieldGroup and adding it to the collection of the second FieldGroup. I have attached a sample that demonstrates this behavior with the use of a button.

var field = dataGrid.DefaultFieldLayout.Fields["Price"];
infoGroup.Children.Remove(field);
shippingInfoGroup.Children.Add(field);

You can always submit a new product idea (or vote for an existing one) at http://ideas.infragistics.com/. The product ideas site allows you to track the progress of your ideas at any time, see how many votes it got, read comments from other developers in the community, and see if someone from the product team has additional questions for you.

Steps to create your idea:
               
1. Log into the Infragistics Product Ideas site at http://ideas.infragistics.com (creating a new login if needed).
2. Navigate to the product / platform channel of your choice (e.g. WPF, Windows Forms, ASP.NET, HTML5 / Ignite UI, iOS / NucliOS, etc.)
3. Add your product idea and be sure to be specific and provide as much detail as possible.
* Explain the context in which a feature would be used, why it is needed, why it can’t be accomplished today, and who would benefit from it. You can even add screenshots to build a stronger case. Remember that for your suggestion to be successful, you need other members of the community to vote for it. Be convincing!
* [FORUMS: “Include a link to this thread”] in your idea so product management will be able to look back at this case. 

If you have any questions, please let me know.
