I will try and word this as carefully as possible as Ui coding is confusing enough!

I have a UI screen that displays a list of info in rows. In order to minimize size and not overload the user with info, I have broken up the results across 5 'stacks' within the 'instance'.

The question is, how do I show or hide these stacks of each instance after I have built the list without having to rebuild it again?

Incase I am not making sense, here is an outline of the UI screen code. The stacks in red are located outside the main grid and are a part of the instance section. I need to know how to show/hide them after building the list of entries.

Code: 
<Context ColorSet="Beige_Black_Alpha" Font="TwCenMT18" FontStyle="Shadow" >

	<Grid ID="BackgroundBox" Size="1200,600" Offset="10,0" Anchor="C,C" Style="Grid9DetailFive140" ConsumeMouse="1">

Easier to answer if you can just paste in the Lua that creates the instance (either by using the InstanceManager or the BuildInstanceForControl function)
 
Here is the code. I have snipped out all irrelevant code.

Code: 
local SHOW_GENERAL				= 1
local SHOW_MILITARY_UNITS		= 2
local SHOW_INDUSTRIAL			= 3
local SHOW_MILITARY_PRODUCTION	= 4
local SHOW_AGRICULTURAL			= 5

[B]function UpdateDisplay(showButton)[/B]

	Controls.RegionMainStack:DestroyAllChildren()

	-- Loop through region data
	for key, regionName in ipairs(g_RegionNames) do
	
		local instance = {}
		ContextPtr:BuildInstanceForControl( "RegionInstance", instance, Controls.RegionMainStack )

		...
		<Populate all fields in instance. We do not touch any stacks here>
		...

	if showButton == SHOW_GENERAL then
		instance.RegionGeneralInfoStack:SetHide( false )
		instance.RegionMilitaryInfoStack:SetHide( true )
		instance.RegionIndustrialInfoStack:SetHide( true )
		instance.RegionMilitaryProdInfoStack:SetHide( true )
		instance.RegionAgriculturalInfoStack:SetHide( true )
		
	elseif showButton == SHOW_MILITARY_UNITS then
		instance.RegionGeneralInfoStack:SetHide( true )
		instance.RegionMilitaryInfoStack:SetHide( false )
		instance.RegionIndustrialInfoStack:SetHide( true )
		instance.RegionMilitaryProdInfoStack:SetHide( true )
		instance.RegionAgriculturalInfoStack:SetHide( true )

	elseif showButton == SHOW_INDUSTRIAL then
		instance.RegionGeneralInfoStack:SetHide( true )
		instance.RegionMilitaryInfoStack:SetHide( true )
		instance.RegionIndustrialInfoStack:SetHide( false )
		instance.RegionMilitaryProdInfoStack:SetHide( true )
		instance.RegionAgriculturalInfoStack:SetHide( true )
		
	elseif showButton == SHOW_MILITARY_PRODUCTION then
		instance.RegionGeneralInfoStack:SetHide( true )
		instance.RegionMilitaryInfoStack:SetHide( true )
		instance.RegionIndustrialInfoStack:SetHide( true )
		instance.RegionMilitaryProdInfoStack:SetHide( false )
		instance.RegionAgriculturalInfoStack:SetHide( true )
		
	elseif showButton == SHOW_AGRICULTURAL then
		instance.RegionGeneralInfoStack:SetHide( true )
		instance.RegionMilitaryInfoStack:SetHide( true )
		instance.RegionIndustrialInfoStack:SetHide( true )
		instance.RegionMilitaryProdInfoStack:SetHide( true )
		instance.RegionAgriculturalInfoStack:SetHide( false )
	end
        
       end -- for statement
	
	Controls.RegionMainStack:CalculateSize();
        Controls.RegionScrollPanel:ReprocessAnchoring();
        Controls.RegionScrollPanel:CalculateInternalSize();

ContextPtr:SetHide(true)
 
This should do what I think you're asking

Code: 
local SHOW_GENERAL				= 1
local SHOW_MILITARY_UNITS		= 2
local SHOW_INDUSTRIAL			= 3
local SHOW_MILITARY_PRODUCTION	= 4
local SHOW_AGRICULTURAL			= 5

local allStacks = {}
local g_lastShowButton = SHOW_GENERAL

function UpdateDisplay()

	Controls.RegionMainStack:DestroyAllChildren()
	allStacks[SHOW_GENERAL] = {}
	allStacks[SHOW_MILITARY_UNITS] = {}
	allStacks[SHOW_INDUSTRIAL] = {}
	allStacks[SHOW_MILITARY_PRODUCTION] = {}
	allStacks[SHOW_AGRICULTURAL] = {}

	-- Loop through region data
	for key, regionName in ipairs(g_RegionNames) do
	
		local instance = {}
		ContextPtr:BuildInstanceForControl( "RegionInstance", instance, Controls.RegionMainStack )

		...
		<Populate all fields in instance. We do not touch any stacks here>
		...

		table.insert(allStacks[SHOW_GENERAL], instance.RegionGeneralInfoStack)
		table.insert(allStacks[SHOW_MILITARY_UNITS], instance.RegionMilitaryInfoStack)
		table.insert(allStacks[SHOW_INDUSTRIAL], instance.RegionIndustrialInfoStack)
		table.insert(allStacks[SHOW_MILITARY_PRODUCTION], instance.RegionMilitaryProdInfoStack)
		table.insert(allStacks[SHOW_AGRICULTURAL], instance.RegionAgriculturalInfoStack)
	end
	
	ShowStack(g_lastShowButton)
        
end

function ShowStack(showButton)
	for i = SHOW_GENERAL, SHOW_AGRICULTURAL, 1 do
		for _, stack in pairs(allStacks[i]) do
			stack:SetHide(showButton != i)
		end
	end

	Controls.RegionMainStack:CalculateSize();
    Controls.RegionScrollPanel:ReprocessAnchoring();
    Controls.RegionScrollPanel:CalculateInternalSize();
	
	g_lastShowButton = showButton
end


-------------------------------------------------
-- Show/Hide Enabler
-------------------------------------------------
function ShowHideHandler( bIsHide )
	if( not bIsHide ) then
		GetRegionDynamicInfo(Game.GetActivePlayer())
		UpdateDisplay()
	end
end
ContextPtr:SetShowHideHandler( ShowHideHandler )

-------------------------------------------------
-- Info Buttons Clicked
-------------------------------------------------
function OnGeneralInfoButton()
	ShowStack(SHOW_GENERAL)
end
Controls.GeneralInfoButton:RegisterCallback( Mouse.eLClick, OnGeneralInfoButton );

// etc for the other 4 button callbacks
 
Unfortunately it did not work. Aside from the != which I easily picked up and changed to ~= , the code seems to be failing on this line:

Code: 
function ShowStack(showButton)
	for i =SHOW_GENERAL, SHOW_AGRICULTURAL, 1 do
		[COLOR="Red"]for key, stack in pairs(allStacks[i]) do[/COLOR]
			stack:SetHide(showButton ~= i)
		end
	end

	Controls.RegionMainStack:CalculateSize();
    Controls.RegionScrollPanel:ReprocessAnchoring();
    Controls.RegionScrollPanel:CalculateInternalSize();
	
	g_lastShowButton = showButton

end

with the following error:

Code: 
Runtime Error: C:\Users\user\Documents\My Games\Sid Meier's Civilization 5\MODS\Great Patriotic War (v 1)\UI\RegionsOverview.lua:393: bad argument #1 to 'pairs' (table expected, got nil)

I assume the instances are not carrying through once out of the loop!

EDIT: But dont worry, I can live with a complete reload ;)
 
For that line to fail, one of

Code: 
	allStacks[SHOW_GENERAL] = {}
	allStacks[SHOW_MILITARY_UNITS] = {}
	allStacks[SHOW_INDUSTRIAL] = {}
	allStacks[SHOW_MILITARY_PRODUCTION] = {}
	allStacks[SHOW_AGRICULTURAL] = {}
can't of executed - so check for copy/paste/edit errors (or SHOW_GENERAL .. SHOW_AGRICULTURAL aren't consecutive ints)
