How to Save / Restore an IntervalSelector value

[PopovMP]

Hello,

I wan to save and recover the value of an IntervalSelector.

I'm trying to set its value in a XElement on Save:

// NTTabPage member. Required for storing elements to workspace
protected override void Save(XElement element)
{
	if (element == null)
		return;

	// Save the currently selected interval
	if (intervalSelector != null)
	{
		element.Add(new XElement("IntervalValue") {Value = intervalSelector.Interval.Value.ToString()});
		element.Add(new XElement("IntervalValue2") {Value = intervalSelector.Interval.Value2.ToString()});
	}
}

and later to recover it like that:

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

	// Restore the previously selected instrument
	var intervalValue = element.Element("IntervalValue");
	var intervalValue2 = element.Element("IntervalValue2");
	if (intervalValue != null && !string.IsNullOrEmpty(intervalValue.Value) &&
		intervalValue2 != null && !string.IsNullOrEmpty(intervalValue2.Value))
		intervalSelector.Interval = new BarsPeriod
		{
			Value = Int32.Parse(intervalValue.Value),
			Value2 = Int32.Parse(intervalValue2.Value)
		};
}

However, it works only when "Duplicate" tab, but not when close / open the add on window.

How to fix it?

It appears that this save / restore methods work when we save the workspace

Hi PopovMP,

have a look at the "AddOnFramework"-Sample at the very bottom lines. There you can find exactly what you want.

Hello PopovMP,

Yes, windows can only save with the workspace when using NinjaScript tools.

Update: Please refer to the AddonShellNoTabs_NT8 example which also implements workspace persistence.

GoSPvC is also correct, the Addon Framework NinjaScript Basic demonstrates this as well.
