cant seem to make 3 regions visible / hidden via a procedure - case statement ?

paperclix

using reportbuilder12 we have 3 regions "layered over each other"

i want to create a procedure to show each region (address) depending on the result of a string field in my case country

region 3 is back layer (say UK), region 2 is middle layer (say EUROPE), region 1 is top layer (say US)

so i need

if address['country'] = 'US' then region1.visible :-true
if address['country'] = 'EUROPE' then region1.visible :-false
if address['country'] = 'UK' then region1.visible :-false AND region2.visible :-false

problem is that using an if statement then you cannot use an AND function

has anyone used the case statement to do something like this?

You need to bracket each condition separately in Delphi. But why don't you hide all three regions first - and then just turn the one on that you need based on the data?

microtronx

region1.visible:=(address['country'] = 'US'); // Show region1 if country = US
region2.visible:=(address['country'] = 'EUROPE'); // show region2 if country = EUROPE

//region1.visible:=not (address['country'] = 'EUROPE'); // hide region1 if country=EUROPE

// if country = UK then region1 is already hidden and region2 is also hidden, so we don't need to check for this line:
// if address['country'] = 'UK' then region1.visible :-false AND region2.visible :-false
