Great thread! I have a question regarding the UI ExpressionEdit Control. What I want to do is utilize this in a custom step type. When the user adds one of these custom step types in a TestStand sequence, I want them to be able to add Local variables with selections made on a VI via the Expression Browser.. I can get the Browser to comes up no problem but it won't allow me to insert new variables. I.e. I can't figure out which property and/or method I need to do this.
