Restricting user input

Property validation allows you to control the values that can be saved for a property. Property validation cannot prevent users from entering incorrect values in all cases, but it can apply rules to what the user enters and inform the user of incorrect input. You can apply several types of validation to a property, either individually or in combination:

Each of the validation options is described in the following procedure.

To restrict user input:

  1. In Configurator, expand Property Sets in the configuration tree to display the property sets.
  2. Expand the property set that contains the property for which you want to configure validation. The names of the properties currently in the selected property set appear.
  3. Select the desired property in the configuration tree. The property’s property pages appear in the right pane.

Note    The Enable for scripting option must be selected and VBScript name must be complete for the Validation and Assignment pages to be active.

  1. Click the Validation tab. The property’s validation options appear.
  2. Click the Edit button to edit the property.
  3. Click options or type values using the descriptions in the following table.
