Stack overflow when clicked on the Themes tab in the Editor

C282304 · Post by **C282304** » Wed Mar 04, 2009 5:04 pm

I am using the ShowEditor method to display the chart settings at run time. When I click on the Themes tab I get the stack overflow exception. I also get index out of bounds when I click on the Series tab but it continues.

The best I can tell is that it is trying to serialize my business objects and getting in some kind of cicular referencing. I am using datasets for the series. I have marked all the public properties of my business objects with attribute [XmlIgnore].

When I put breakpoints in these property getter I still see that it is being called. I just want to disable this serialization.

It shows run time version v1.1.4322 and version 2.0.2546.16098 and it is a TCHart for .NET 2.0 with VS2005.

Any idea what is the cause and how to fix it?

Thanks in advance

Hi C282304,

We couldn't reproduce your problem here. We recommend that install new version, check your problem that is solved,we could say if your version works correctly or not

Thanks,

I did update the version to 2.0.3309.32489. But the problem still exists.

Here is another behavior that may give you a clue that something is wrong with my series. May be you can isolate it
I have a Series class inheriting from FastLine.

In the dialog box that shows up as a result of calling ShowEditor() I see my series ( 2nd level ) Under Chart tab ( 1st level ). I can enable and disable it and the chart updates immediately.

But Under the Series tab ( 1st level ) I get Index out of range exception in the method ShowSeriesForm(). It then continues but the Format tab ( 2nd level ) is empty.

Thanks

Hi C282304,

I think that your problem is produced, because you doesn't have editor difined for your custom series an is necessary to define an editor. You can find solution here, specifically you see post of 14 of September and exactly example for RegisterSeries.

But to be able to do this, you need version 3 of TeeChartForNet, because in version 2 aren't possible do this solution.

Thanks for the help.

Version 3 requires .NET 3.0, is that right? If so we have no plans to upgrade to .NET 3.0 until later in the year.

In the earlier post your support person has suggested changing the source code for version 2. Is there any way we can get that done? Either you can build it for us or how do we get the source code?

Also can you point me to good examples of the code where you can inherit from one of the seriers specifically Fast line?

Thanks again for the help.

Hi C282304,

No, TeeChart for .NET v3 also runs with Microsoft .NET Framework v1.1 and v2.0.

In the earlier post your support person has suggested changing the source code for version 2. Is there any way we can get that done? Either you can build it for us or how do we get the source code?

We don't use to make custom features for clients unless they make into production releases of TeeChart. However you may get TeeChart for .NET sourcecode as an option. You should contact our Sales Dept. at sales at steema dot com for that.

Also can you point me to good examples of the code where you can inherit from one of the seriers specifically Fast line?

There's an interesting example of custom series in the thread Sandra pointed you:

http://www.teechart.net/support/viewtopic.php?t=6590

I also recommend you to read the thread below about the options and improvements TeeChart for .NET v3 offers in terms of creating custom series.

http://www.teechart.net/support/viewtopic.php?t=7019

I can't think of an exampe using FastLine series now but two interesting examples are also available here:

http://www.teechart.net/support/viewtopic.php?t=4309
http://www.teechart.net/support/viewtopic.php?t=4110

Hope this helps!

Thanks a lot for your prompt help. I upgraded to V3 and use the register service call as mentioned in the article. That solved my out bounds error in the Series tab in the chart editor.

I am still having problem with the Themes tab though.

I went and removed as much as possible - all my public properties that used my business objects. This made - the stack overflow reported in the original post go away. But now I am getting this error when clicking on the themes tab

Can you point to some thing in the custome Serie missing?

Thanks

Hi C282304,

The only thing I can think of for now is custom series serialization issue as described in the thread below. Notice it is 2 page long.

http://www.teechart.net/support/viewtopic.php?t=7019

For more information about this issue please read Tutorial 19 - Custom Serialization. Tutorials can be found at TeeChart's program group.

If this doesn't help please send us a simple example project we can run "as-is" to reproduce the problem here. You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

I am going to look into how to serialize my custome series.

Is there a way to disable the themes tab in the Chart Editor through code?

Thanks

Narcís · Post by **Narcís** » Tue Mar 10, 2009 8:14 am

Hi C282304,

Yes, you can do it as shown in the All Features\Welcome !\Components\ChartController\ChartController Editor example at the features demo, available at TeeChart's program group.

C282304 · Post by **C282304** » Tue Mar 10, 2009 2:37 pm

Thanks for all the help. For now I am going to disable the themes tab.
So this issue can be considered closed.

Going forward it seems the serialization code could use some improvement. If the inherited class does not want to be serialized or some objects inside the inherited series class want to be ignored then that should be allowed.

Thanks again.

Hi C282304,

Ok, I've added your request to the wish-list to be considered for inclusion in future releases.
