Adding an Execute Button

With the <vdl-execute-button> element you can add a button to a view that allows a user to submit a scenario for execution with a given execution mode, optionally setting a scalar entity first.
By default, an execute button uses the first scenario and sets the execution mode to RUN. It will have the caption Run Mode - for example: 
<vdl-execute-button></vdl-execute-button>
To change the execution mode, scenario and caption: 
<vdl-execute-button 
    mode="load"
    caption="Load the second scenario"
    scenario="1">
</vdl-execute-button>
You can set the mode to be any custom execution mode defined in the model, or one of the standard modes - LOAD and RUN - for example: 
<vdl-execute-button 
    mode="EVALUATE_SEGMENTS"  
    caption="Evaluate Segments">
</vdl-execute-button>
It can be useful to set a scalar before execution. The value attribute accepts an expression so you can calculate the value based on the current values of other model entities: 
<vdl-execute-button 
    entity="LIMIT" 
    value=”=getLimit()”
    caption="Evaluate limited dataset">
</vdl-execute-button>
