PaintCellBackground not firing whole row

i want to color a row when a checkbox is checked (in paintcellbackground)

if me.LastRowIndex>0 then
  if me.CellCheckBoxStateAt(row,0)=DesktopCheckBox.VisualStates.Checked then
    g.DrawingColor = &cD2FFF3
    g.FillRectangle(0, 0, g.Width, g.Height)
  end if 
end if

but it is only coloring the cell with the checkbox, only when i resize the window it is coloring the whole row.

the docu says:
If you pass a -1 as the row or column parameter, it will redraw the specified entire row or column

but is does not…

Move the


into the clicked event and let the paint happen.

Never call something from a paint that can cause a recursive loop


Shouldn’t that be

if row<= me.LastRowIndex then

You should be checking the CellCheckBoxState of rows that don’t exist. You’ll get an exception.
