Using splitAt and setcolumnhidden

how do I use splitAt and setcolumnhidden at the same time.

if i use: mygrid.splitat(3) and setcolumnhidden(2,true) it works fine… but when I try setcolumnhidden(5,true)

I get the below message:

Error:‘this.hdr.rows.0.cells[…]’ is null or not an object

There was some limitation in setColumnHidden functionality in case of “split” mode.
You can
    a) move setcolumnhidden call before grid.splitAt command
    b) contact us directly at - we will send you latest version of file, which most probably resolve issue.
