Hi all,
I have created a map using the native object, i have a number of layers that i want to show/hide based on a user selection.
I have created a field for the user selection..i.e.
ViewLayer:
Load * inline [
ViewLayer
Layer1
Layer2
Layer3
];
The user can then select 1 or more layers from the field which i then want to show or hide in the map.
I am then using the following expression within the 'Calculation Condition' against each layer..
SubStringCount(Concat([ViewLayer], '|'), 'Layer 1')
If i use the above expression in a text object it return 1 (when nothing is selected from the ViewLayer field, however, if i do the same in QlikView, 0 is displayed unless i actually make a selection and select Layer 1. It seems that in QS it counts the value even its its a possible value whereas in QV it only counts it if selected.
I can get around this by creating separate fields for each layer, but then that means that the user will have to make selections on multiple fields instead of a single field (not very user friendly).
Does anyone know of a workaround where i can use a single field for the user to select.
What i want is for the map to hide all layers unless they are selected from the field.
Note that the user can make multiple selections, which is why i am using the concat() function in the expression above.
I have attached a QVF with a sample.
Any help would be appreciated.
I am using version FEB 2020
