Is there a way to insert an image (ostensibly a transparent background image) in a SpreadProcessing worksheet cell like there is in Excel? If not, is there a way to accomplish the same thing with Cell styles? Attached is an example.
Those images, however, will not act as a background for the cell or the worksheet. They are rather additional objects that will lay over the worksheet independent of the cell.
By looking at the screenshot, I assume you are trying to mark a cell with a red triangle shape, is that right? That is what happens in MS Excel if you add a note.
If you'd like to add notes to cells, that is also possible using the RadSpreadProcessing. Instructions can be found in the Notes - RadSpreadProcessing section of the documentation.
Please let me know if you have any questions.
