Hi,
When the ASPxImageGallery control on the page is load or clicked the message is displayed.
" Uncought TypeError: Cannot read property 'GetActiveItemIndex' of null"
"Uncought TypeError: Cannot read property 'Show' of null "
How to solve it?
Thank's.

Hello,
We haven't received similar reports before, so it's difficult to determine the cause of the issue based on this information. Would you please elaborate on your scenario and send us your ASPxImageGallery markup and code snippets that will allow us to reproduce the issue from scratch. Alternatively, attach a simple runnable project, so we can research the issue in action.
If this issue is browser-specific, specify the browser family/version:
- Detailed information about the browser: make a screenshot of the "Help -> About …" dialog.
- Browser/Document mode settings - press the F12 key to invoke the Dev Toolbar (for the IE browser only).
We're looking forward to your reply.
Hi Artem,
In my tests I could see that the problem occurs when using the components ASPxPageControl , ASPxDashboardViewer and ASPxImageGallery .
Follows the example attached and the IE Screenshot is in the archive.
Thank you so much.
Jhon.
