Custom Properties workspace

All study objects have standard properties for which you view, define, and modify values in the Properties Browser.

If you want to provide additional information about a study object, then you create custom properties in the Central Designer Administrator application. A custom property is a user-defined or default characteristic of a study object. You can create custom properties for study designs, study elements, study events, forms, items, codelists, codelist items, logical schemas, data sets, and data series.

After an administrator creates custom properties for the study objects in the Central Designer Administrator application, Central Designer users can define values for custom properties in the Properties Browser in the Central Designer application.

Custom properties are organized in both applications by study object and then by grouping. A grouping is a default or user-provided value used to organize custom properties of a study object.

For example, you can create a custom property that allows Central Designer users to select the dictionary used to code an item. You can specify values for the dictionaries, and users can either select a dictionary from a list or type a dictionary name.

Note: In the Central Designer application, all custom properties appear in the Categories tree, so users can include custom properties and their values in search parameters.
