changing Column Header in a grid

How could I change the Column Header for one of the columns in a grid?

I don’t want it dynamic. All I am trying to do is :

If my flagVar = 1, then column header = “xyz”
else “pqr”.

I am setting the Header while initializing the grid and then I simply use clearandLoad() API to refresh the XML.

In this case, using grid.setHeader() doesn’t work.

Please advice.

You may try to use setColLabel() method:
