Disabling Strategy after validating UI Properties

[GARZONJ]

I have some UI properties and want to make sure the strategy does not move forward if two UI properties are not equal to each other.

I am validating the two UI properties in the Configure state (this state is reached once the user clicks in the OK or Apply button in the Strategy Configuration window).

Is there an easy way to prevent/stop the execution of the strategy if these two UI properties are not the same?

Example:

if (UIProperty1 != UIProperty2)
CANCEL the Strategy execution

I would like it to continue in the Strategy Configuration window. I don't think this is possible based on some posts that I found. If that is the case, how can I stop the strategy from executing and also close the Strategy Configuration window?

Thanks,

Hello GARZONJ,

As long as the properties are the same type thats fine to compare them to each other.

A return in OnBarUpdate() when this condition is true, would prevent the code below the return from executing.

if (UIProperty1 != UIProperty2)
{
return;
}

Alternatively, if you want to disable the strategy you can call CloseStrategy();.

There are no supported methods to close the Strategies window. That would be unexpected behavior that looks like a bug to many people.

Just to clarify, if I do the first the technique, the strategy is not disabled.
Technique 1:
if (UIProperty1 != UIProperty2)
{
return;
}

If I do technique 2, the strategy is disabled.
Technique 2:
CloseStrategy()


Sound like technique 2 is the only way to disable a strategy.

So to validate UI properties, I add my logic to a method. This method I can run it either at Configure state or at the beginning of the OnBarUpdate(). If the validation is not in accordance to my logic, I can set a boolean like haltProcess. If halProcess is true (because the validation is not in accordance to my logic), then CloseStrategy().


At a high level, is this the only way to validate UI properties?

Hello GARZONJ,

If you would like to run logic like a comparison, or a return, or CloseStrategy(), this must done in a method after State reached State.DataLoaded.
