Multiple images in a single column

[Charles Carlin]

Previously I was doing this using an embedded grid control in the column and then just using a single row with multiple columns (one for each image). By removing the grid lines this ooked perfect.

However after doing some memory load testing it became obvious that this was a poor solution. When loading in a couple of thousand rows the memory load became way to large.

Is there a better (less memory) way to display multiple images (icons or bitmaps) in a single column?

One other solution would be to derive your own cell control that just displayed the bitmaps. Take a look at the ImageCellModel and ImageCellRenderer classes that are part of the Grid\Samples\In Depth\ExcelMarker sample. They derive from the static celltype and display a bitmap in a cell. I think all you would need to do is to modify the OnDraw to draw a series of bitmaps in a row of rectangles instead of one bitmap into the whole cell rect.

The hard part of doing this would be to determine (somehow) what bitmaps should be drawn. But I assume you had to come up with some scheme for your grid solution. Maybe the same scheme will work for you image cell solution.

Excellent suggestion. I was easily able to use the ImageGridCell and modify it to display a list of images. Plus it is much more memory friendly then keeping an extra grid control per row around.
