In WPF, when you place a BlobField in a ViewModelColumn, you can set taggedvalue WindowsFileFilter to influence what files should be filtered out in the file open dialog.

If the Blob is of Blobtype Image. we use this as default:

Image files (*.jpg, *.jpeg, *.jpe, *.jfif, *.png, *.gif) | *.jpg; *.jpeg; *.jpe; *.jfif; *.png; *.gif

If not Blobtype Image, we have it blank (all files show).
