Mygrid first column not visible using setColumnHidden method with SmartRendering

HI All,

I have enabled smart rendering using following method :: mygrid.enableSmartRendering(true);

I fetch 200 entries from server and load in mygrid. After that i trigger a UI button which in turn call the method (mygrid.setColumnHidden(0,false)) to make the first column visible, but this column does not visible.

mygrid first column visible by three ways (workaround) :

          (1) After manually scrolling over grid entries(200) so that entries get rendered into grid and then trigger UI button(show).
          (2) Reduce the zoom level (press ctrl + "-") till all entry visible , refresh the page then press UI button to show the first column.  
          (3) Remove smart rendering. ( //mygrid.enableSmartRendering(true);)

Please let me know why i am not able to visible column with smart rendering ?

Thanks & Regards,
Shinoy

Unfortunately I was not able to reproduce your issue locally. setColumnHidden() works well for me with the grid in the smart rendering mode.
You may try to call the
mygrid.setSizes()
or
mygrid.callEvent("onGridReconstructed",[]);
to repaint your grid.
If the problem still occurs for you please, provide a complete demo or a demo link, where the problem can be reconstructed locally.
