Serialization problems at design-time

[Luigi S.]

Hi all,
I experienced an annoying problem on an user frame containing a TChart.
A few time after I open the frame in the designer, a message box containing the following error :

Code: Select all

Type 'System.Drawing.Color, System.Drawing, Version 2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' does not implement the IXmlSerializable interface therefore can not proceed with serialization. 

appears.

The message box is shown several times (about ten) and the error seems periodical (once I confirmed the ten errors, I can continue to work normally but after a few time the error reoccurs ...)
It also happens when i compile my solution, but oddly there is no problem at runtime .

Any suggestions ?

Thanks.

Yeh I kept having this problem - nothing more annoying than a damn messagebox coming up every 2 seconds when you try to go to the designer view...

To fix the error in mine I put:-

Code: Select all

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden), Browsable(false)]

above all the Properties in the class deriving from TChart.

edit: you may also need to delete the control from the form and re-add it once you have done the above and recompiled it.

Hi Luigi,

Your problem be the same as I described here:

Removing Steema.TeeChart.Styles.ColorList references from *.resx file solves the issue. Could you please check if it works fine for you?

Thanks in advance.

Hi Luigi,

Thanks in advance.

I didn't found any reference to the ColorList class in .resx files, but I found one in the *_Designer.cs file of the implied User Frame....

Code: Select all

this.seriesMixed.Colors = ((Steema.TeeChart.Styles.ColorList)(resources.GetObject("seriesMixed.Colors")));

I solved removing the Shape series that used it (I forgot it into the frame , but I don't actually need it !!!).
For now this solution seems to work ...

Thanks again

[Luigi S.]

For now this solution seems to work ...

Mmmm.... no, not exactly ... there are still some problems .
The designer seems to "move" the ColorList, adding automatically the line

Code: Select all

this.seriesMixed.Colors = ((Steema.TeeChart.Styles.ColorList)(resources.GetObject("seriesMixed.Colors")));

for another series (seriesMixed) that I have into the chart...

The content of the "seriesMixed.Colors" resource is a blob :

Code: Select all

<data name="seriesMixed.Colors" mimetype="application/x-microsoft.net.object.binary.base64">
  <value>

Hi Luigi,

Ok, could you 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.

Hi Luigi,

Ok, I will try to provide a sample application as soon as possible.

Thanks again.

Hi Narcís,
I just uploaded a test application (TestTChart.zip) onto your upload page.

To reproduce the problem, just change some property in the TChart inside the UCFrameChart control and save the project itself (or recompile the solution).

Thanks.

Hi Luigi,

Thanks for the example project. I could reproduce the issue here and added it (TF02013653) to the defect list to be investigated for next releases.

Hi Luigi,

We have been investigating the issue here now and we don't think it is a bug. Openning UCFrameChart.resx in design viw, in the example project you sent and removing the row seriesMixed.Colors (of type ColorList), saving it and then reopening the UCFrameChart.cs solved the problem for us here. Could you please check if this solves the problem at your end?

Thanks in advance.

First of all, I apologize for my late answer ...

Anyway: yes, removing the row in the resource file seems to solve the problem..

Thanks again.

Mmmmm... actually this solves the problem, but the entry inside the .resx file is recreated (I don't know exactly in which moment ... maybe when the frame is closed or when some modifications are made in the designer) and so it is necessary to remove the entry each time it is recreated ...

I investigated a bit and the the entry in the resx seems to be recreated when a control (e.g. a button or a label) is added on the frame and once the project is recompiled...

It is possible to avoid design-time serialization of seriesMixed.Colors property into the .resx file and set it at run-time from the code ?

Thanks.

[Narcís]

Hi Luigi,

No, I'm afraid this is not possible.

Hi Luigi,

No, I'm afraid this is not possible.

OK, I take it all back .... But do you think the serialization problem could be fixed in a future release of TeeChart ?

Thanks.
