We have a situation where we have a grid that has three bands. If the user checks a box on the second band we do not want the user to be able to add a record to the third band. What would be the best way to accomplish that?
Hello James,
Maybe you could achieve desired behavior using "CheckBoxVisibility" and AllowAddNew properties. Please take a look at the attached sample for more details. If you have any questions, do not hesitate to write us

Thanks Georgi, I will give that a try when I have a moment today. By the way I like your avatar. Is that an SU-33? It's got to be a member of the Flanker family.
If you have any questions regarding attached sample, please do not hesitate to write us.
