I tried to reproduce the reported behavior using the provided code, but the control is rendered properly on my side (when made visible).
- Are there any custom CSS styles applied on the page containing the ImageEditor? Can you remove them for the test and see whether the issue is still reproducible?
- Is there a chance that you are using the ImageEditor into a Load-balanced environment? If so, please take a look at the following blog post and apply the needed configurations: How to integrate RadControls for ASP.NET AJAX in a WebFarm or WebGarden scenario
If none of the above helps in solving the case, can you please isolate the problematic configuration into a sample runnable page replicating the case
and send it for a further investigation?
Thanks in advance for your cooperation.
