Steema Central

A number of times while going through the TChart for .Net Examples demo I get an unhandled exception for example on the Tools\SeriesBand Tooldemo click the Edit button, then the Brush button the following error is generated. This "Value cannot be null" error pops up in several other places to.

Is this something that can be fixed quickly as I would like to release a new version of my app with Tchart V3, as it (V3) resolves some other issues I had with V2.

just-in-time (JIT) debugging instead of this dialog box.

Hi Adrian,

A number of times while going through the TChart for .Net Examples demo I get an unhandled exception for example on the Tools\SeriesBand Tooldemo click the Edit button, then the Brush button the following error is generated. This "Value cannot be null" error pops up in several other places to.

Should I change any specific property? I'm not able to reproduce the problem here using latest TeeChart for .NET v3 maintenance release available at the client area.

What I noticed is that if you zoom a chart with this tool it produces an error. I've already added this defect to our bug list to be fixed for future releases.

try this,

edit --> series --> format--> format-- then the pattern button... the dialog closes and then reopens. try it again and the error pops

"Value cannot be null. Parameter name: value"

infact, it appears that clicking the pattern button just about anywhere causes this error

Hi Adrian,

I'm not able to reproduce the problem here doing this:

1. In the example you mentioned above, double click in the textbox to edit the chart.
2. Go to the Series -> Format tab and click the Pattern button.

Is that the button I should use to reproduce the issue?

Thanks in advance!

did that and got the error

Hi Adrian,

It's strange, I can not reproduce this here using the demo in the latest maintenance release nor using our latest demo project.

Should I do anything else besides clicking the Pattern button?

Thanks in advance.

Are you using the same version of a maintenance release not yet shipped.... I'm using the demo trial version downloaded last week 3.2.2831.26852

using the demo that shiped with 3.2.2831.26852 go to
Welcome --> Chart Styles --> Bar --> Self Stached.

double click the yellow area to edit the chart
then Series --> Format --> Format

then click the Pattern button...

then

Narcis,
I'll be in my office lat tonight... which I think is early your time, if you like I can run a Webex session to show you what I mean? Send me an email asap if you think this might help.

this error also occurs if the colour square in the series list of the tchart editor is double clicked.

Hi Adrian,

Thanks for the information and collaboration.

Are you using the same version of a maintenance release not yet shipped.... I'm using the demo trial version downloaded last week 3.2.2831.26852

I was using the registered version of the same release (Build 3.2.2831.26851). Then I installed the evaluation version to test with the very same build as you and could reproduce the problem here.

Finally I tested using our current demo sources which uses our TeeChart sources as well and could not reproduce the problem either. So you may expect this being fixed in the next maintenance release.

These issues are still present in release 3.2.2866.23885

This problem is making the TCHART component unuseable for my application!!!!

Hi Adrian,

Thanks for the information. I've finally found that this only happens in VS2003 and works fine in VS2005. I've added this defect (TF020125779) to our bug list to be fixed for next releases.

Fixed in release 3.2.2868.26902
Thanks
