ScaleTransform name cannot be found in the name scope of System.Windows.Controls.ControlTemplate

Hello,

I'm not sure what I'm doing wrong here.

I have a simple graph with 4 plots.  When I click on the Y or X axis last/first value (to change the range), I get this exception:

'ScaleTransform' name cannot be found in the name scope of 'System.Windows.Controls.ControlTemplate'

I'm pretty sure some time ago this used to work.  Could someone please give me a pointer here?  Thanks!

<ni:Graph x:Name="GraphRefNode">
    <ni:Graph.Axes>
        <ni:AxisInt32 Orientation="Horizontal" Label="Frame"/>
        <ni:AxisDouble/>
    </ni:Graph.Axes>
    <ni:Graph.Plots>
        <ni:Plot Label="X" />
        <ni:Plot Label="Y" />
        <ni:Plot Label="Z" />
        <ni:Plot Label="S" />
    </ni:Graph.Plots>
</ni:Graph>

I created a new WPF project and copied your example XAML into the main page: unfortunately, this did not reproduce the issue you are seeing.

Do you have a full project example using this XAML that does reproduce the issue?

Hi Paul,

You put me on the path to trace this issue (by process of elimination) to this open source GUI library:

https://github.com/MaterialDesignInXAML/MaterialDesignInXamlToolkit

If I don't include one of the Merged Dictionaries, all works as expected.

I can provide you with the bare-bones project to look at this but I can only assume you don't want to look at it because it's happening due to 3rd party library 🙂

Let me know either way.

Thank you!

Yes, if you have tracked the issue down to a 3rd-party library, then I would suggest contacting the 3rd party 🙂

Hi Paul,

Just FYI, this issue is mysteriously gone with NI 2019.  I didn't get to the bottom of this but in the end it doesn't really matter anymore.

So just FYI whoever runs into something similar.
