hi,
I work on custom control(inherit RadComboBox) with multi column combobox. For header is used HeaderTemplate and on ItemsRequested I create RadComboBoxItem for each element. For each element I want to display a picture from Table. If put in RadComboBoxItem an Image control and fill ImageUrl with path it works exactly what I want.
The question is how to show picture from table? I'm able to read the picture into System.Drawing.Image control and make some extra changes on the image but I don't now how to display the image in the RadComboBox.
Any suggestions how to do it?

Hi Marjan,
This is quite an interesting case.
It is possible to achieve the desired functionality by implementing your own HttpHandler which serves the Images from the database. In other words, the HttpHandler will load an Image based on an ID, for example, and will return it.
Finally, you can have RadComboBoxItems with Image controls in them which have urls pointing to the HttpHandler specifying the ID of the Image to be loaded.
Please read the articles linked below to find out how HttpHandlers are created, registered and how they can be used to serve Images:

Thanks for your reply,
I'll try with HttpHandler, but it seems not easy way.
