Daniel,

If you use a grid, traditionally you'd need an image column containing all the image controls you need, using dynamiccurrentcontrol code to change the current control per row. If there are lots of potential images then you need to include them all and the grid can get very sluggish.

However, using a VFP trick you can show any image you like in a grid, without including it as a separate column control.

1) You're not limited to one changing image per column. Drop as many image controls as you want to show at once into a container, then include the container in your image column.
2) E.g. if each row needs to show images for pdf status, printed status and emailed status, create a container with a row of 3 images and include that in your image column. Works the same whether you need 1 image or a row of 5 images per record.
E.g. you could have mycontainer.imgPDF, mycontainer.imgPrint and mycontainer.imgEmail images side by side in a wide container, as currentcontrol in a column wide enough to show the whole container with its images.
3) To change the .picture properties per row: check out the backstyle_access method/event. Pretty simple: set the image.picture properties in the backstyle_access method and it'll update per row.

E.g.

* Change pictures according to document status
This.imgPdf.Picture = icase( vDoc.pdfstat='Y', 'bitmaps/docstatus_pdfdone.png',vDoc.pdfstat='E', 'bitmaps/docstatus_pdferr.png','bitmaps/docstatus_pdftodo.png')
This.imgPrint.Picture = 'bitmaps/docstatus_'+trim(vDoc.ds_print)+'.png'
This.imgEmail.Picture = 'bitmaps/docstatus_'+trim(vDoc.ds_email)+'.png'
Return This.backstyle

Simple as that! Now you can show one or more images per row with infinite variability, without having to load all the images into separate columns with separate dynamiccurrentcontrol code. Just make sure the images are accessible/included in your project as usual and you're done.
