Mouse clicks lost when using AjaxToolkit TabControl

richheim · Post by **richheim** » Mon Jun 30, 2008 5:49 pm

I have an application that uses ASP.NET AJAX Toolkit's tab control to display several panels on a web page, some of which contain steema charts. I need to capture the X,Y coordinates of a mouse click on a given chart, embedded in a tab panel. However, it appears that once added to the toolkit's TabContaner Control, the mouse clicks from the steema chart aren't being recognized. I have other controls - such as asp.net datagrids, for which this is not an issue.

I have a sample project I can send you, if that would help.
Below is the apsx page code:

thanks,
Rich

Hi richheim,

Yes please, send us the example project. You can post it at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

I've uploaded the files.
look for "from _stemma.zip".

unzip and open as a web site in VS 2005. Use ZoomUpdatePanel.aspx as your start page.

thanks,
Rich

Hello Rich,

Just to check that we're looking for the correct issue. The ZoomUpdatePanel.aspx Chart in your project responds to correctly to zooms and reports the correct click co-ordinates on the Chart (tested in Internet Explorer and Firefox). Are you looking to use the click co-ordinates in an additional way? Is there another test we should run?

With thanks.
Regards,
Marc Meumann

No - the ZoomUpdatePanel.aspx responds to zoom, but not to mouse clicks. At least not for me.
It was respondiong to mouse clicks before I added the tab container. It
stopped once the tab container was added.

I guess I should say, more explicitly, that the Webchat1_ClickBackground method isn't being called.

thanks again,
rich

Hi Rich,

Thanks for the information. Your project has been tested to work fine here using our current TeeChart for .NET v3 sources that we expect to include in the next maintenance release by the end of this week. We have reviewed WebChart's sources and we have noticed a significant change affecting chart naming tag which would also fix this issue.
