Hi Gerald,
Replace this
Eval(“this.hello = function()
{
window.parent.App.Window1.HelloWorld();
}
“)
By
Private Sub RunJavaScriptCode()
Me.Eval("App.Window1.HelloWorld();")End Sub
Take a look to a sample on attachement
Happy coding,
Kevin(ITG)
Hi Dino,
it looks like this information is not yet included in our new documentation.
Here are the steps to migrate from Wisej 1.x to Wisej 2.x:

Hi Jevaso,
ChartJS version 2.5.20 had some major issues that we had to release a new build for it.
If you can’t install the new NuGet package, you can always compile the extension from the source code available here: iceteagroup/wisej-extensions: Extensions to Wisej. See https://wisej.com. (github.com)
It is advised that you add the reference yourself while you wait for the next Wisej version so that you don’t get bottlenecked and always get work done!
HTH,
Alaa
Hi Paul,
thanks! I´ve just updated the link.
Best regards
Frank
Hi Jevaso,
please use version 2.5.21 of our ChartJS extension. Why is it not working for you to upgrade?
See also Alaa´s answer of other ways to resolve this:

Hi Chris,
There’s an updated version of the extension (version 2.5.21) can you please give it a try and see if it fixes your issue?

To update this thread. Wisej 3 beta is out. Wisej is running on .NET 5 and .NET 6 on Windows, Linux, MacOS. We also have it running on small devices and controllers like a Raspberry Pi and smaller industrial controllers.
The public Wisej 3 beta will start soon.
Hi Cristian,
for what type of chart you want have two y axes?
Best regards
Frank
Hi Andrew,
can you please wrap up a sample and either post it here or send it to us directly.
From the information you give, it´s unclear to me where UserData.DataType might have been reset.
Best regards
Frank
I have try this.chart.data.datasets[0].hidden
don’t return error, but return always false
Sorry Levie, I have an error: : ‘this.widget is undefined’
The 3.0 beta is already available to Technology Partners. Will be open at the end of November (or few days late).
Any update on expected 3.0 beta release date?
Hi Page,
You can add this to Default.html to disable the browser warnings:
<script>
Wisej.onLoad = function () {
qx.log.Logger.unregister(qx.log.appender.Native);
}
</script>

Levie
Hi Page,
The TabControl and TabPage controls don’t have an AutoSize property. The property is supposed to be hidden. :-).
Sorry for the inconvenience!
Best,
Levie
Hi Andrew,
I don’t think this is a Wisej-specific issue. If you attach a small sample we can verify it.
Best,
Levie
You can check the hidden status of the client-side widget’s dataset using this:
var isHidden = await this.chartJS1.EvalAsync("this.widget.data.datasets[0].hidden");
AlertBox.Show($"Hidden Status from Client: {isHidden}");
HTH,
Levie
to complement my colleague answer. I adjunt a sample code for how to verify selected node and checked/uncheck node.
I hope will helpful
Sorry, I meant App Pool.
But if you are in debug in VS then IIS and Visual Studio are not running your code. It’s IIS Express. Unless your VS is attached to IIS.
Is the access denied exception handled and you catch it because VS has the exceptions settings on? If yes, turn it off and the problem is solved.
Otherwise it’s a permission problem, not a Wisej issue. It simply tries to write to the system’s temp and the access denies is not even for the file that Wisej is writing.
You can also use a PictureBox. In any case //svr1/ is not a valid URL.
