[CLOSED] Column Locking not working when using GridPanel.Reconfigure
I am trying to lock few columns on my grid, but setting Locked = True seems to have no effect.
Below is a sample to reproduce the problem -
When you click 'Show Offices', it loads up the Office data and in the 'GetEmployeesColumns' method, I've set the first 2 columns to be locked.
