c# - Show bound byte array as an image in DataListView -


i'm using objectlistview controls set, datalistview. here code.

datasource of control:

datalistview1.datasource = this.viewmodel.dataset;

where dataset populated by:

this.viewmodel.dataset = hsglobals.ctx.entities<product>().all()                         .where(p => productidlist.contains(p.id)).select(p => new                         {                             nazwa = p.name,                             kod = p.code,                             dostępność = p.avaiblequantity,                             typ = p.producttype.name,                             miara = p.measureunit.name,                             grafika = p.productimage.image                         }).tolist();

grafika byte array - image obtained database.

when datalistview displayed, grafika column shows type of field - system.byte[].

what have display image?

i've tried imagegetter , renderer properties no success.

your initial approach should work, if attach instance of brightideassoftware.imagerenderer renderer of column.

for imagerenderer, image can sourced from:

  • a byte-array (normally when image shown stored value in database)
  • an int, treated index image list
  • a string, treated first file name, , failing index image list
  • an icollection of ints or strings, drawn consecutive images

assuming byte-stream contains valid data create bitmap should do.

edit: make sure ownerdraw property of olv set true, iirc requirement custom images drawn.
