Problems with Zoomtool and <body onload="">

Centrii · Post by **Centrii** » Wed Oct 28, 2009 10:00 am

Hello Steema Team,

I am using TChart for .Net Version 3.5.3470.15474
Now I have problems with the ZoomTool. As soon I´m using the Zoomtool in a WebChart
the <body onload=alert('test')> doesn´t work anymore. If I delete the Zoomtool again everthing is fine.
Did you have Problems like this before and can you please tell me how to solve this problem?

regards Centrii

Hi Centrii,

Have you seen the topics suggested here in the WebChart ZoomTool related threads?

Hi Yeray,

Yes I have seen the topics, but without any solution for me.
My problem is that the ZoomTool overrides my javascript window.body.onload ="DoSomething()"
with the compiled TChart javascript window.onload = function()
This causes that my DoSomething() Function doesn´t work anymore.

Hi Narcis,

Did you find a solution or a workaround?
If there is a Bugfix-Number for this problem, is it possible that I can have this Number?

Hello Centrii,

This problem is due to WebChart's need of the onload event to initialise the layers for the zoom Chart. Looking at the problem you have reported we were unable to see a workaround so have made a modification to the TeeChart code permitting the addition of a custom 'onload' function that will be called if present in your on-page code.

The fix will be included with the next TeeChart for .NET maintenance release for v3 and v4. We will add a section to Tutorial 9, 'ASP.NET Applications' to describe the functionality.

Regards,
Marc Meumann

Hi Centrii,

As Marc told you, this was fixed in v3 too as you can see in the release notes corresponding to the latest update:

http://www.steema.com/files/public/teec ... elease.txt

Bug fix number 7, without internal tracker id, is the bug discussed here. Can you please check if latest release available solves the problem at your end?

Thanks in advance.

Hi Narcís,

Thanks for the quick reply.
I installed the new update and tried it with my Source Code, but it is not working.
Marc told me that you will add a Section in Tutorial 9, 'ASP.NET Applications', but the
TeeChart for .NET v3 Update Build doesn´t include the new Tutorial.
Where can I find this one?

Thanks in Advance

Hello Centrii,

The tutorial section is a brief explanation of use, quickest for me to add it here:

Window onload event

When a Zoom or Scroll Tool is added to your WebChart it requires to use the Window.onload event to initialse characteristics of the Tool. If you require to further use the onload event for your own needs then please add a new function to the page called windowOnload and place your code there.

eg. optionally in <HEAD> section of page
Code: Select all
<script language=javascript> 

function windowOnload()  {
    window.status = new Date().getTime();
 } 
</script>

Please let us know if that doesn't work correctly for you.

Regards,
Marc
