Hi,

i am using

frm.TChart1.Export.Template.IncludeData = True
frm.TChart1.Export.Template.Save(File)

to export my Charts, but when i try to load it back with

frm.TChart1.Import.Template.Load(File)

only the series are displayed, but no Data is there?

during the Export i give the File not an ten extension....

Thanks

Hello AGF,

Using next code I couldn't reproduce your problem and last version of TeeChart.Net:

Code: Select all

 Steema.TeeChart.Styles.Line line1, line2;
        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            tChart2.Aspect.View3D = false;
            line1 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
            line2 = new Steema.TeeChart.Styles.Line(tChart2.Chart);
            line1.FillSampleValues();
            line2.FillSampleValues();
            tChart1.Dock = DockStyle.Top;
            tChart2.Dock = DockStyle.Bottom;
            tChart1.Export.Template.Save("C:\\tmp\\file1.ten");
        }

        private void button1_Click(object sender, EventArgs e)
        {
            tChart2.Import.Template.Load("C:\\tmp\\file1.ten");
        }

Could you check if you can reproduce your problem using previous code? If your problem doesn't appear in previous code, please, try to arrange a simple project because we can reproduce exactly your problem here.

On the other hand, you can tell us which version of TeeChart.Net are you using now?

Thanks

Hello AGF,
I think you can help you translate C# to VB.NET code and viceversa you can use one those tools:
http://carlosag.net/Tools/CodeTranslator/Default.aspx
http://www.developerfusion.com/tools/co ... arp-to-vb/

Please, try to convert my code and modified it or send us a simple project,so we can reproduce your problem here. On the other hand, tell us which version you can use, exactly for example:
Last version of TeeChart.Net
Build 4.1.2011.04193

Thanks,

Dear Sandra,

it is the same like before! I add some series and save them to an template file with the code i send you.

the (file) comes from an SaveFileDialog an i have tested the *ten and my custom extention with no success.

when i use the TEditor component for Export and Import it works well!

Thanks

Hello AGF,

Can you please, send us a simple project we run as-is here, so we can reproduce exactly, your problem?

Thanks,

Dear Sandra,

it is not possible to make an simple example,because i use teechart inside of an complex framework. If you provide me an email adress from to my accout e mail, i can give you more informations about that .....

Thanks

Hello,

You could explain private details mailing to "info at steema dot com" referencing this thread.
If you want to send us private files, you could use our upload page.

Hello,

I understand that the framework you use makes it difficult for you to arrange a simple example project isolated from that framework.
However, it's difficult for us too to analyze the problem without being able to debug it, etc.

From what you said in a previous message, using a TEditor component works fine while using a SaveFileDialog doesn't, isn't it?
I'd debug it to see the exact difference between both behaviors. Doesn't SaveFileDialog give you the same string than the TEditor? Why?

Thanks

Hello,

It sounds like if you were using some series or tool that is exported correctly but fails when trying to be imported.
Could you please send us the .ten file that is failing when trying to be imported? I see you mentioned you've customized the exportation. Is the problem also occurring when exporting&importing using unmodified TeeChart routines?

Dear Yeray,

i am not sure. When i use the methods from the teeEditor it works, when i try it with code it does not.

I have attached some examples...

Hello,

I've been testing your .ten and .cvo files. I could load all them without problems with the code below except for one: test3.ten

Code: Select all

tChart1.Import.Template.Load(fileName);

The test3.ten file seems to have 2 series and fails when trying to load the first one because for some reason the SeriesCollection is empty.
It would be helpful if you could give us more information about the chart that generated this ten file. What series types are in it? Is it possible for you to send us the code used to create and format the chart?
Thanks in advance.
