TcxEditorRowProperties Class

Stores vertical grid row settings in unbound mode.

Declaration

delphi

TcxEditorRowProperties = class(
    TcxCustomEditorRowProperties
)

Remarks

A vertical grid row contains one header and displays one data cell per column. The TcxEditorRowProperties class implements general vertical grid row settings in unbound data access mode.

In-Place Editors

A vertical grid row can use any editor shipped with the ExpressEditors Library as an in-place editor for cell edit operations. An in-place editor instance exists (and, therefore, has its own WinAPI handle) only when a row cell is being edited. Otherwise, the column displays a static editor image for resource usage optimization.

To switch between available in-place editors, you can use the EditPropertiesClass property. Use the EditProperties property to configure the in-place editor associated with the vertical grid row.

In-Place Editors and Repository Items

Alternatively, you can assign an edit repository item component to the RepositoryItem property and use the repository item to define the active in-place editor and customize its settings.

Note

If an edit repository item is assigned to the RepositoryItem property, EditProperties, EditPropertiesClass, and EditPropertiesClassName properties have no effect.

Multiple In-Place Editors in One Row

You can handle OnGetEditProperties and OnGetEditingProperties events to dynamically change the assigned in-place editor and its settings based on custom conditions.

Important

Do not change EditPropertiesClass, EditPropertiesClassName, and EditProperties property values directly in OnGetEditProperties and OnGetEditingProperties event handlers.

To change the active editor and modify its settings safely within these event handlers, use the RepositoryItem property and TcxEditRepositoryItem class descendants.
