I have a Grid "Drive - SSD", and one of the fields/columns is "Drive Type".  I Ctrl+C copied the value "SSD" from the Drive Type field in one item.  Then I tried Ctrl+V to paste this value into the Drive Type field in some other items in the grid.  Instead of pasting "SSD", IQ pasted the IDItem value of the item from which I copied the "Drive Type" value.  IDItem was not one of the columns I had displayed in the grid.  Since had just added some columns to the grid, I thought that might be the source of the problem.  I refreshed the grid but this did not solve the problem.  I closed the grid and reopened it; the columns were not in the same order that I had placed them before closing the grid.  However, now my attempt to paste the value "SSD" from one "Drive Type" cell to another did work properly.  Maybe the addition and rearranging of columns messed up the ability to copy and paste values, and closing and reopening the grid was required to make that work properly.
