Setting UIHint parameters from feature edit function

graham_lock

Hi,

Is there a way to apply UIHints from code - for example make a field read only within the feature edit function if certain other criterion are met?

Thank you.

No, you cannot set UIHints dynamically.

But…there is a work around with editing logic.

Make two identical fields, one that is read only another that is not read only.

Make another field that has UIHint.Always_hidden, is a boolean, and controls the visibility of the other two fields.

When the read-only condition is met, set that field with editing logic so that the editable field is hidden and the read only is visible.

Example:

export function EditingLogicFunction(context is Context, id is Id, olddefinition is map, definition is map, isEditing is boolean) returns map
{
// condition for visibility
definition.isVisible = definition.myLengthControl > 50*millimeter;
// Update the value
definition.myLengthReadOnly = definition.myLength;
return definition;

}
annotation { "Feature Type Name" : "My Feature", "Feature Type Description" : "", "Editing Logic Function":"EditingLogicFunction" }
export const myFeature = defineFeature(function(context is Context, id is Id, definition is map)
precondition
{
    annotation { "Name" : "Controls other field readonly" }
    isLength(definition.myLengthControl, LENGTH_BOUNDS);

    annotation { "Name" : "control Visiblity", "UIHint" : UIHint.ALWAYS_HIDDEN }
    definition.isVisible is boolean;


    if (definition.isVisible)
    {
        annotation { "Name" : "My field" }
        isLength(definition.myLength, LENGTH_BOUNDS);
    }
    if (!definition.isVisible)
    {
        annotation { "Name" : "My field", "UIHint" : UIHint.READ_ONLY }
        isLength(definition.myLengthReadOnly, LENGTH_BOUNDS);
    }


}
{
    // Define the function's action
});

Thank you for answering and taking the time to generate an example, much appreciated.
