There is no simple way to achieve such functionality.
If you want to have values in filter different from one in the grid cells, you need to redefine how values collected. onCollectValues event can be used for that.
To resolve this we thought of using seperate column for showing image using img as a column type. But we are not able to achive scenario where we don’t want to show image.
Can you please tell me how to not display image for a cell (source of the image is blank)?
