Value list filter

The Value List filter is very useful for providing a set of keywords. Many tools have a predefined set of keywords, such as the Field Type parameter found in the Add Field tool, or the JoinAttributes parameter of many of the tools in the Overlay toolset.

A Value List filter can be used for Long and Double data types. For these types, you enter the allowable numeric values.

A Value List can be used for Boolean data types. For Boolean data types, the Value List contains two values: the true value and the false value. The true value is always the first value in the list. These values are used in command line for specifying the value. See, for example, Add Field and the {NULLABLE | NON_NULLABLE} keywords used for the IsNullable property.

To apply Value List filter, follow the steps below:

  1. In the Catalog window or ArcToolbox window, right-click the model tool and click Properties. Or do one of the following:

  2. Click the Parameters tab.
  3. Select the parameter for which you want to apply the filter, click the cell, then choose the Value List filter from the drop-down list as shown in the illustration below:
