Hi Said,
Though we are not sure how you are setting the red background in specific cells, we assume that you are using the SetCellStyle method of the C1FlexGrid to apply a custom style to those cells.
In this case, you can use the GetCellStyle method of the C1FlexGrid to retrieve that custom style from the cells and determine which cells are red. Please see the attached sample project for reference - FlexGridCellColor.zip
If your implementation is different, please update this sample project to reflect it so we can investigate further and assist you better.
Best Regards,
Kartik
