We analyzed on our end, but we are unable to reproduce the reported issue. We are able to hide the column by binding the value for IsHidden property. We have prepared a sample with GridTemplateColumn and we are binding the Active property to IsHidden property from ViewModel and then GridTemplateColumn is hided. Please modify the sample based on your scenario and share the exact scenario with us. It would be helpful for us to resolve the issue. You can download the sample from following location:
