Interactivity lost on Teechart .net control

RonenL · Post by **RonenL** » Tue Jan 01, 2008 1:15 pm

In our application we have some pages where we use TeeChart as ActiveX and some pages where we use TeeChart .net.
After installing TeeChart Pro v7 ActiveX with Unicode (TeeChart7Activex.exe and TeeChartAX7MultiLangUnicode.exe installed) on a WEB Server machine the page that has Teechart as a .net control started showing the graph as an image and it does not responde correctly to a click on the graph. We tried to reinstall the Teechart .net V3 but it did not help. Please advise.

Hi MeirS,

TeeChart for .NET can't be used as a live object in web applications as the TeeChart ActiveX version. The .NET version is rendered server-side an displayed as an image at the client. However, some interactivity can also be achieved as you can see in the live ASP.NET demo, specially in the Interacting with Charts. Full demo project is also included with TeeChart for .NET installation.

Of corse the page with the .net graph is not fully interactive as an ActiveX version, but it still reacted to events such as click, and zoom untill we reinstalled the last release (7.0.1.4 instead of 7.0.1.1) of ActiveX V7 TeeChart7Activex.exe and TeeChartAX7MultiLangUnicode.exe

Hi MeirS,

I'm a little bit confused. I initially thought you were comparing TeeChart Pro ActiveX versus TeeChart for .NET. Could you please confirm the exact TeeChart version you are using and in which environment you are using it?

Thanks in advance.

In our application we have some pages where we use TeeChart as ActiveX (TeeChart Pro v7 ActiveX) and some pages where we use TeeChart .net (TeeChart for .NET v3).
Last week we installed TeeChartAX7MultiLangUnicode.exe on a WEB Server machine. After this installation our ActiveX pages work well (asp and aspx), but a graph on our not ActiveX .net page (TeeChart for .NET v3) stopped to react to a client side click at all or sometimes react not properly at all.
This problem does not exist on our local machines (the same version of TeeChart Pro v7 ActiveX and the same version of TeeChart for .NET v3)

Hello,

There should be no relation between use of TeeChart AX and the .NET version on the same web server. Most of our test machines are setup to use all versions in parallel and we haven't encountered any inter-version problems to date.

Depending on what clientside click functionality you have configured to the ASP.NET application there are most likely calls back to the server. You'll need to debug the click activity to locate the cause of the problem. What are the visible symptoms?

If the install of the AX version has caused a problem it may be due to a procedural step during the installation, perhaps the removal or renaming of a folder. Please review that procedure.

We did not have any problems with the AX V7 installation but we get an exception during the installation of the .net V3 on our Server Machine.
The visible symptoms of the incorrect functionality of the .net graph are that the graph behaves like an image:
1. We get an image bar with buttons to save/print/email/open on the upper left corner
2. When right-clicking on the graph we get the image popup menu (Save Picture as/E-mail Picture and so on).

The zoom tool sometimes works and unzoom - does not work. We have a server side event handler for the click that does not react properly to click.

Hello,

Re. "exception during the installation of the .net V3 on our Server Machine."

We advise not to use the TeeChart (AX or NET) installers on the server as they install the TeeChart designtime keys. For the .NET installation you should only need to install the TeeChart.dll file along with the application files of your .NET project or solution.

Re. Visible symptoms 1 and 2
These are the symptoms that appear only after installing the ActiveX version? Are the browser versions being used the same as for your test environment? It may be the javascript support of the browser version that is causing the problem.

Re. "The zoom tool sometimes works and unzoom - does not work"
Is the network connection very slow? Is it possible that you are trying to zoom before all of the page has loaded?

Re. "Server side event handler for the click that does not react properly to click"
Any error message that might help us?

Do you have a public page example we could connect to or a private page that you could send us the link to for us to take a closer look?

With thanks.
