Question

I have problem with rendering images in ListView in winforms app based on .NET 3.5.

In ListView control I use LargeImageList as thumbnails.

App works correctly in Win 7 – images in thumbnails are OK but if app runs in Win XP images in thumbnails are rendered bad.

Difference between rendering in Win 7 and Win Xp is on this .

What can cause this behavior?

EDITED: Thank you all for response and advice.It’s solved. I use another control not winforms listview.

Answer 1

You can try using the free ObjectListView control for this purpose. You can download it from http://objectlistview.sourceforge.net.

Basic Implementation

1. Replace your regular ListView control with an ObjectListView.
2. Create a class that contains the fields you want to display on the ObjectListView.
   This is necessary because OLV does not directly use a ListViewItem to display elements.
3. Create columns (in code) in the OLV and specify the property (from step 2) that will be displayed for the column.
4. Set the ImageGetter property of the column for which you want to display an image (usually the first column) to a function that returns an Image, string or int which corresponds to the image you want to display for the item.
   If a function returns string or int, then the image in the OLV’s LargeImageList or SmallImageList will be displayed for the item.
5. Create an Enumerable collection of the items you want to display and attach it to the OLV using the SetObjects or AddObjects method.
6. In the function for returning the image to be displayed for an item, render the image with GDI (or anyhow you want) and return it for display in the OLV.
