Hello Markus,

I did some more research into the issue with large images not showing when they're stored in ImageLists.  As it turns out, our developers are aware of the issue.  They have determined that resolving the issue would cause a large number of breaking changes throughout our Windows Forms control suite.

I would recommend setting the images on the tools individually.  You can set both the small image and the large image in the SharedProps and they'll apply to every instance of the tool.

Hello everyone,

can someone give me some advices or example how specify a small image list and a large image list for the ribbon and use differnt image sizes for individual tools? Showing small images in one group and showing large images in another group under the same tab or other tab-groups.

I'm using 11.2.20112.2050.

Regards

Markus

This happens also to me a few times. I have now specified a image list small and a image list large where the images are loaded. The image lists are assigned to the toolbar manager properties 'ImageListLarge' and 'ImageListSmall'. The sizes are correctly set.

The images in the toolbar are gone, but are still visible in the image list. If I specify the tool property preferred size = Default, the small image is shown, but in the other way preferred size = Large, no image is shown.

Initially I have set the images to large and all they were visible. I can not say what happens, but are images are not visible anymore.

I guess there is a bug in handling the image lists. If I browse the properties of the ribbon group -> tools -> shared props -> apperance large -> appearance -> image: always the small image name is set and I can not change this selecting the prefered size and assigning an image from large image list.

Hello,

As it turns out, without a reliable way to consistently reproduce the issue, it's not possible for us to determine why the issue is happening or how to prevent it from happening.

Unfortunately, I'm not sure what I did to produce the issue in the first place.  It was essentially a "here today, gone tomorrow" kind of incident.  Nothing out of the ordinary was done to create this issue.

I can't clearly remember if this was the same for the first time, but I believe this is only affecting one form in particular.  

Unsure if this is related, but my ultragrids often lose any formatting I've applied (hiding columns, changing header text) and need the data schema refreshed at design time.  I've taken to programming these changes at run-time instead.  I've read that this can happen when you change the structure of the dataset it's bound to, but I've had it happen as frequently as between every debug session - not at all in response to a dataset change.  If the design view of the form is not displayed, it's often unaffected so I tend to only look at design view when I absolutely have to.
