TcxDBEditorRow Class
A data-aware vertical grid row.
Declaration
TcxDBEditorRow = class(
TcxCustomEditorRow
)Remarks
A vertical grid row contains one header and displays one data cell per column.
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 Properties.EditPropertiesClass property. Use the Properties.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 Properties.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 Properties.RepositoryItem property, Properties.EditProperties, Properties.EditPropertiesClass, and Properties.EditPropertiesClassName properties have no effect.
Multiple In-Place Editors in One Row
You can handle Properties.OnGetEditProperties and Properties.OnGetEditingProperties events to dynamically change the assigned in-place editor and its settings based on custom conditions.
Important
Do not change Properties.EditPropertiesClass, Properties.EditPropertiesClassName, and Properties.EditProperties property values directly in Properties.OnGetEditProperties and Properties.OnGetEditingProperties event handlers.
To change the active editor and modify its settings safely within these event handlers, use the Properties.RepositoryItem property and TcxEditRepositoryItem class descendants.
