Issue

I have a sub-Dialog collection and, based on a check box value, would like to either add or delete an item from the collection. I have the code for adding it…what is the code for removing it?

Solution

The following will delete all items in a dialog collection (in this example called "sub"):

%[RepeatBlockWhile(ThisDialog.sub.count>0)]
    %[ThisDialog.Sub.delete(1)]
%[EndBlock]

The following will delete a specific collection item based on its name:

%[i=1]
%[RepeatBlockWhile(i<=ThisDialog.sub.count)]
    %[KeepBlockIf(ThisDialog.sub[i]._name = "ABC")]
        %[ThisDialog.Sub.delete(i)]
        %[i=i-1]
    %[EndBlock]
%[i=i+1]
%[EndBlock]
