Summary

How can I add more columns to a table when switching a switch?

Hey,

Thanks in advance for any help.
I would like to show more columns for a table when the "More details" switch is turned on.
So far I have tried to set the Data.TableColumns property of the table using the Call component method but to no avail.
I also tried the simpler case of changing the text of a label with setProperty and params binded to:
[

"Text",
"newvalue"

]
I think the property name is wrong, but I can't find any documentation on this.

Thanks, Niek
