Hi Experts,

Exist some way to display external images in grid columns when the data source only contains links to the images ? In my data base only have the link, but I need show the image inside of the grid. I'm using delphi xe4 with firebird and IBO Objects

Could someone help me?

Thanks
Alexandre

Maybe this will help - http://stackoverflow.com/questions/11067833/delphi-show-images-without-download

You can use this function (compiled and tested using Delphi 2010) to download a file over HTTP and store it in a TBitMap. It'll read all file types that have a registered support in Delphi's TGraphic hiearachy, and will auto-detect BMP, GIF, JPG and PNG file formats:

It is possible with using OnDrawColumnCell event. You can use TImageList for caching images. First, go through all records to cache images. This way you will have imageindex = recordNo. Resize them to size equal to cell size. Then draw images.
Some articles about draw image in grid.
