Error when when closing a tab that has XamRadialGauge
posted

 

Hi,

I get the following error when a tab is closed which has a XamRadialGauge. 

System.ArgumentException: '-25' is not a valid value for property 'Width'.

I've prepared a sample project that reproduces the error but couldn't attach the project as a zip file because of the error I get while adding zip file. Therefore I attached the MainWindow.xaml file with txt extension.

I tried to track down the error and found that it was the RadialGaugeTickMarkGroup causing the problem. But I don't know how to solve it. Apparently I can not give up on tickmarks! So I need an immediate solution to this error.

Can anyone help?

Thanks in advance

    Hello,

    Try using the Gauge as direct content of the tab instead of a content template.

        <StackPanel>
        <Button Content="CloseTab"
                Command="{x:Static igt:TabControlCommands.CloseSelected}"
                CommandTarget="{Binding ElementName=tcMain}" />
        <igt:XamTabControl x:Name="tcMain"
                           AllowTabClosing="True"
                           SelectedIndex="0">
            <igt:TabItemEx Header="Tab1">
                <ig:XamRadialGauge Margin="2 2 2 2"
