Hello bugo11,

It would be saved and restored with the IWorkspacePersistence restore and save methods.

protected override void Restore(XElement element)
{
if (element == null)
return;

XElement instrumentElement = element.Element("Instrument");
if (instrumentElement != null && !string.IsNullOrEmpty(instrumentElement.Value))
Instrument = Cbi.Instrument.GetInstrument(instrumentElement.Value);
}

protected override void Save(XElement element)
{
if (element == null)
return;

if (Instrument != null)
element.Add(new XElement("Instrument") { Value = Instrument.FullName });
}

Hey Chelsea,
I do have this code in my addon.xaml.cs
but still the color does not restore and grayed out when restarting the program
also, same thing is happaning with your Addon Example, the color is initialized on restart.

hope you can help me solve this.

Hello bugo11,

If you are referring to the AddonShell example, this does not implement this code to restore the Instrument property and does not implement the code for window linking. (Please review the code and you will see this code is not there.) Without the code implemented, the instrument linking will not restore with the workspace.

Testing with IInstrumentProvider and restoring the instrument, I am not able to reproduce. The linked color is restoring with the workspace.

Hi again Chelsea, thanks for the fast reply
i'm reffering to your addon framework example

https://ninjatrader.com/support/helpGuides/nt8/samples/Addon_Framework_NinjaScript_Basic.zip

the window does not save the color selected in this window
thanks in advance

Hello bugo11,

I am not able to reproduce.

Below is a link to a video showing the color linking is saved and restored with the workspace.

Hey again Chelsea ,
I've been able to find the problem, but this produce another problem

the addon i'm building have few tabs, each different XAML and XAML.cs files.
i was able to create a window with all the tabs when

TabControlManager.SetFactory(tc, new AddOnFrameworkWindowFactory());

is deleted, then i was able to create new tabs with

tc.AddNTTabPage(new NinjaTraderAddOnProject.AddOnPage());

(while changing the AddOnPage to the next page name)

now i see that deleting the SetFactory mathod is breaking the linking mechanism.

is there any way to create different tabs while maintaing the link mechanism?

thank you in advance

Hello bugo11,

I'm not certain. The example I have provided you has tabs and has window linking. Are you finding the InstrumentLinkTest script is inadequate for showing how to use window linking with a tab control?

May I confirm that you were able to reproduce the issue using the AddonFrameworkBasic and have different results than what I have shown in the video?

Hi Chelsea,
thank you for your reply
it seems like the addonframework i used was slightly modified, after loading a fresh code it was fixed.

also i was able to figure how to add new uniqe tabs and keep the linking mechanism.

so thank you!
