  The PaintSortIndicator rectangle does not scale. (V12)
  
  It always seems to remain at 15x15 px.
  
  Any suggestions?

  Thanks in advance

  Well Ruchir, I had a lot of issues with scaling in the past (it’s not stable per monitor) Also look at my post of 27-oct-2019
  
  I found out that if you scale per monitor, turn off SpreadScaleMode and set row heights etc. by code all suddenly works as expected. I’ts also very stable now.

  Is there a way to set de preffered location by code?
  
  PaintSortIndicator does not return the correct rectangle.

  Kind Regards,

  Hi,

  Is there a way to set de preffered location by code? PaintSortIndicator does not return the correct rectangle.
  
  Do you meant to ask for how to define the sort indicator location? If yes, there is no a way to move the position of the sort indicator.
  
  However, if you create a custom celltype, you can create your own headers and implement your own painting of the sort indicator. You would also need to catch when it is clicked, so you can programmatically sort the Spread.
  
  You can learn more about how to create custom cell type by referring to the following documentation link:

  Hi Ruchir,

  Using already a custom ColumnHeaderRenderer which inherits from the FlatColumnHeaderRenderer. Another custom cell type is not my first choice.
  
  Setting SpreadScaleMode to ScaleMode.ZoomDpiSupport does not change anything. The PaintSortIndicator rectangle (clickable area) doesnt even change by zooming Spread. So I think this could be a bug.
