Hello,

I am resuming this old thread because my problem is exactly the same (U++ 11300, MS2017).
My GridCtrl has 16 columns and the one in position 15 is hided.
Then an OptionButton hide/show it when pressed. Here is the code:

void VegaTab1::ShowInfoCol()
{  
   if (optGrid.Get()) {
   	  grid.GetColumn(15).Hidden(false);
   	  grid.Repaint(true, false);
   }
   else {
   	  grid.GetColumn(15).Hidden(true);
   	  grid.Repaint(true, false);
   }
}

If I show/hide that column several times, I observe that the grid looks each time differently. In particular column 15 (the one I hide/show) decrease its width constantly up to become very little after many show/hide.
It seems the grid is not recalculating properly its dimensions.

Is this a bug? Is there a better way to achieve the same result?

Thanks,
Luigi
