Select the Evaluate option if you want to allow evaluation of dynamic, indirect expressions (SBN expressions). Enter an SBN expression in the corresponding field using the square bracket notation [ ]. The Evaluate option lets you compute and evaluate dynamic property settings at runtime instead of assigning static values at design time.
Some property items are pre-selected as Eval. Check boxes indicate the current settings.
To enable or to disable evaluation for a property
Right-click the property that you want to evaluate at runtime.
