Greetings from Syncfusion Support.
We tried to replicate your reported issue of script error
"col.isForeignColumn is not a function" being thrown even when
no foreignkey is used. So, based on your query, we prepared a sample to
replicate your problem by changing the visibility to true when clicked and
content of the column by the external button. However, the error was not
displayed. So, before providing a solution to your query, we need some
information that will be very useful for us to validate further on our end.
Please share your
complete Grid rendering code.
Please share the version
of your syncfusion package.
Do you want to change
the visibility with an external button?
Kindly share the issue
reproducible sample or replicate your issue in the given sample.
