Problem in XAML export

[iMDuser]

hi,

i'm using version build 4.1.2015.12163.
i have a problem in exporting teechart into XAML.

it seems like a bug in the control.
the issue is related to strike-through.

i attached a picture of the exception i get.

i cannot upload the xaml file also as a text because you block this extention.
here is the xaml

Hello,

In the release notes of TeeChart for .NET version 4.1.2015.12160 we have:

4) [ID1361] http://bugs.teechart.net/show_bug.cgi?id=1361
Text strikeout not functional in XAML exportation.
Fixed.

I have tested the code in this issue using TeeChart.dll version 4.1.2015.12163:

Code: Select all

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

		private void InitializeChart()
		{
			tChart1.AfterDraw += TChart1_AfterDraw;
		}

		private void TChart1_AfterDraw(object sender, Graphics3D g)
		{
			g.Font.Strikeout = true;
			g.TextOut(100, 100, "HELLO WORLD");
		}

		private void button1_Click(object sender, EventArgs e)
		{
			tChart1.Export.Image.XAML.Save(@"C:\tmp\chartstrikeout1.xaml");
		}
	}

I then opened chartstrikeout1.xaml in Visual Studio:

this works as expected. Could you please give me the TeeChart code you used to create the xaml file you posted?

Hi,

Strike-though works for us too, but there is some end case it doesn't work.
Sorry but i cannot post the code of our teechart, it's too long and complicated and scattered over many files.
you can maybe try to investigate what is different from the XAML i posted. the WPF property TextDecorations is set twice.

Hello,

It would be extremely useful to have some code with which we can reproduce the issue. If in the future you discover such code then please pass it to us. In the meantime we will run our own tests.

Hi,

it's not easy for us to give code example because it is deep inside our application.

Is something has been found by you?
i'm sure if you'll give your developers a chance to look on it with the data i posted previously about the issue it will be found

Yes, we have found the issue in TeeChart's source code and have resolved it (see id=2025). This fix will be available in the next maintenance release due out within the next two weeks.
