Remarks

The ExpressEditors Library ships with over 40 data editor types you can use as standalone controls for data input forms or in-place editors embedded into container controls (Data Grid, Tree List, Vertical Grid, Pivot Grid, Ribbon UI, etc.). An in-place editor exists (and, therefore, has its own WinAPI handle) only when a user activates it. Otherwise, the target container control displays a static editor image for resource usage optimization.

Most data editors (such as text, spin, or mask editors) are designed to display data in a specific manner and allow users to edit data. Certain editors (such as bar code or formatted label editors) have no data edit functionality.

The TcxCustomEdit class implements the base functionality common to all data editors.

Main API Members

The list below outlines key members of the TcxCustomEdit class that allow you to configure editors.

Appearance Settings

Style | StyleDisabled | StyleFocused | StyleHot | StyleReadOnly: Allow you to define individual appearance settings for different editor states.

Tip
To apply the same style settings to multiple editors, use a TcxEditStyleController component. If you need to apply the same style settings to all editors in your application, you can use a TcxDefaultEditStyleController component.
Styles: Provides access to individual styles applied to the editor in different states.
Transparent: Specifies if the editor is transparent in GDI render mode.

Clear: Clears the editor.
CopyToClipboard | CutToClipboard | PasteFromClipboard: Allow you to perform clipboard operations.
EditValue: Specifies the edit value.
OnEditing: Allows you to prevent users from activating the editor.
ResetEditValue: Restores the previous edit value before the pending change is applied.
SelectAll: Selects editor content.
ValidateEdit: Validates the display value.

Note

Only data-aware editors publish these API members.

DataBinding: Allows you to bind the editor to data.
CanPostEditValue: Identifies if the data-aware editor can post its edit value to the bound data storage. Only data-aware editors publish this property.
OnPostEditValue: Executes custom code when the editor posts its value to the bound data storage.
PostEditValue: Posts the edit value to the bound data storage.

Editor Settings and Repository Items

ActiveProperties: Provides access to the current editor settings regardless of their source. This property set does not allow you to customize editor settings.
GetPropertiesClass: Returns the actual editor settings type.
Properties: Allows you to customize editor settings directly if the editor does not have an assigned repository item.
RepositoryItem: Specifies a repository item as an external source of editor settings. A repository item has priority over other editor settings.

General-Purpose API Members

AutoSize: Specifies if the editor automatically adjusts its size to fit content.
Enabled: Specifies if the editor is enabled.
CanModify: Identifies if the editor is in read-only mode.
IsEditValidating | IsHiding | IsPosting: Allow you to identify the current operation in the editor.
ShowHint: Specifies if the standalone editor can display hints. To enable hints for an in-place editor in a container control, set its OptionsBehavior.CellHints^[1] property to True.
SupportsSpelling: Identifies if the editor supports the TdxSpellChecker component.
Width | Height: Allow you to explicitly define editor dimensions.

Terminal TcxCustomEdit Class Descendants

Terminal TcxCustomEdit class descendants include all unbound and data-aware editors shipped with the ExpressEditors Library. Do not create TcxCustomEdit class instances. You can derive descendants from the TcxCustomEdit class and override its virtual methods to create custom editors with support for DevExpress Skins and editor integration mechanisms.

Note

Non-editor controls shipped with the ExpressEditors Library are not derived from the TcxCustomEdit class. For example, TcxButton, TcxClock, TcxFilterControl, TcxHeader, and TcxNavigator.
