TChart in WPF

[oxygen]

I've just started using Tcharts in a WPF application. Having added a TChart to the main window, I'm getting the following error when I build the application:

The tag 'TChart' does not exist in XML namespace 'clr-namespace:Steema.TeeChart.WPF;assembly=TeeChart.WPF'.Line 20 Position 10

A reference to TeeChart.WPF exists in the project. I could use some help in figuring out what's missing in my approach and what else I need to be doing.

Also, I've run the TeeChart for .NET native WPF Control by starting the WPF Demo application distributed with the product. When I click on the Serialized Chart tab page, the application produces the error message "WPFDemo2 has stopped working". I'm running windows 7 32 bit. I'm trying to determine what might be going on here and whether the native WPF control is sufficiently stable for use in a commercial application.

Hello oxygen,

Using next xml code I don't have any problems:

Code: Select all

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300"
    xmlns:my="clr-namespace:Steema.TeeChart.WPF;assembly=TeeChart.WPF">
    <Grid>
        <my:TChart Margin="0,0,0,0" Name="tChart1" />
    </Grid>
</Window>

If previous code doesn't solve your problem, Could you please send, us your project so we can reproduce exactly your problem here?

You are right. I couldn't reproduce your problem and I have added it as bug with number [TW16015458]. We will try to fix it for next maintenance releases of TeeChart.Net.

Using the same xaml code that you've provided I get the same error I described previously. Could you please let me know as soon as possible how I can get around this?

Could you send us your project, because we can reproduce your problem exactly here and try to find a solution for this?

Hello oxygen,

As we told you by mail, it seems the problem with your application could be that it is using the .Net Framework 4 Client Profile but the TeeChart.dll. Change the dll or the .NET framework to match them (TeeChart.Client.dll and .Net Framework 4 Client Profile or TeeChart.dll and .Net Framework 4).

Hello oxygen,

I inform that the bug with number (TW16015458) is fixed in a new available version of TeeChart.Net that you can find in Customer download page

Thanks,
