How To

This article will demonstrate how to add a GridViewImageColumn to the grid and populate it asynchronously with images.

Solution

Create a custom GridDataCellElement and in its SetContentCore method start asynchronous loading of the images. When a result comes back, it is saved in the respective RowInfo and the row is invalidated, thus the SetContentCore is called again and this time the image is cached so it is assigned to the cell element.
