This property can be used to store any object that you want to associate with a column. Any type derived from the Object class can be assigned to this property via code. At design time, a specially designed dialog is used to set this property’s value. This dialog enables you to choose the data type and enter the desired value.
The following code snippets (auto-collected from DevExpress Examples) contain references to the Tag property.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
