tChart1.Printer.Preview() is not working on .NET 5

[bairog]

Hello.
I'm using Steema.TeeChart.NET 4.2022.5.26 (that also reproduces with latest 4.2022.8.23) in a .NET 5 Windows Forms application on Windows 10 21H2.
I just added a chart on my form and added a line in it. My code is simple:

Code: Select all

public partial class Form1 : Form
{
        public Form1()
        {
            InitializeComponent();

            line1.FillSampleValues(20);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            tChart1.Printer.Landscape = true;
            tChart1.Printer.Preview();
        }
}

But after clicking the button nothing happends at all. I have no physical printer

or

But all other programs (Paint .NET, etc.) display print preview dialog where all that virtual printers are listed.

So what is wrong with my code?

Same code in .NET Framework 4.8 application (with very same Steema.TeeChart.NET version 4.2022.5.26) works as expected:

do please let us know if it resolves this issue for you.

With latest version print preview dialog now shows up but with default (English) language. I set language in my form constructor with:

Code: Select all

Steema.TeeChart.Languages.Russian.Activate();

but print preview dialog still looks like


P. S. Again, same code in application targeting .NET Framework 4.8 works correctly


P. P. S. Looks like Russian translation is incomplete: 1/100 Inch should be 1/100 Дюйма

Excellent, so id=2551 is fixed.

Steema.TeeChart.Languages.Russian.Activate();

but print preview dialog still looks like

This issue has been resolved, thankfully without the need for a change in the sourcecode. To see it work, you will need to replace:

Code: Select all

Steema.TeeChart.Languages.Russian.Activate();

with:

Code: Select all

Steema.TeeChart.Languages.Russian.Activate<Steema.TeeChart.Languages.Translator>();

Technically it is working now, thank you.
But for me it is quite strange that the same operations require different client code depending on the application target platform.
