Question
Is the price per developer or per company? Does it include royalty-free distribution? We are developing a commercially available software package. Will we have a problem selling our software using your controls? Any license fees that we are not aware of?

Answer
We are distributing the evaluation version of the DataGridColumns .NET assembly within the product license agreement. If you are reading the licensing correctly you need one license for each developer and no licenses for users. Please read the 2nd and 4th paragraphs of the agreement to learn more about that.
