Actually this is an expected behavior and it is related to the alpha compositing
transparency of the color that is used as a background fill. There are several layers in Spreadsheet which are responsible for visualizing the cells' values (CellValuesLayer
) and for editing the value in the cell (CellInputLayer
).When the cell is in edit mode, the CellInputLayer
is positioned upon the CellValuesLayer
. Since the CellInputLayer
is getting the same background as the CellVauesLayer
, if the background color is with high transparency, this can cause the old value in the cell to be visible as well.
To avoid this I would recommend you use a color with low level of transparency.
schattierungColor = Color.FromArgb(255, schattierungColor.R, schattierungColor.G, schattierungColor.B);
I hope this information is helpful. Let us know if you need any further assistance.
