Hello,

Yes, it is possible to make a template column visible from JavaScript in an event like a button click. The following code is an example on how to achieve this.

[code]
var grid = igtbl_getGridById("UltraWebGrid1");
grid.Bands[0].getColumnFromKey("col1").setHidden(false);
[/code]

For further information about the client side programming of the UltraWebGrid please see the following link.

Please let me know if I may be of further assistance with this matter.
