Problem displaying images

0

Hi,

When I display an image in a modal dialog, it does not display correctly the first try (looks like just the top 5% renders, but nothing else does), but if you close the dialog and then re-display it, the image displays correctly.

A simple demo is attached.  I have extracted the classes used from a large application, hence some unused overhead functionality in the demo.

Thanks for your help!

Neil.

Thanks Luca,

Changing to a PictureBox is the way to go.  I did look at that, but couldn’t quite connect the dots to make it work.

The app uploads “documents” (pdfs or images) elsewhere … they are physically stored in the /Resources/UserData/ subfolder, with a database entry record.  So the viewer is supplied with a string eg “Resources/UserData/test1.jpg” to view.  The image does not exist at design time (in properties or a resx).

Could you show how to wire the PictureBox to dynamically display the string?

Thanks,
Neil

The sample app is setting <img src… width=100% height=100%/>

The width and height set to a percentage in html is the percentage of the container but the html you are setting is just the image. Set an actual size for the image, or set a container element with a size. It’s also a lot better if you use the PictureBox control instead of the HtmlPanel (which is scrollable) to show an image.

    Forgot to add that the calls to htmlBox1.Refresh() and Update() don’t do anything. The control is already marked to be updated automatically. The same for pdfViewer1.Update() – doesn’t do anything since it’s already marked for update.
