RepositoryItemComboBox.Items Property

Provides access to the collection of items displayed in the editor's dropdown.

Namespace:DevExpress.XtraEditors.Repository
Assembly:DevExpress.XtraEditors.v19.1.dll

Expanded Syntax

Property value

Type: ComboBoxItemCollection
The collection of items displayed by the editor.

Expanded Remarks

The Items collection stores items displayed in the editor's dropdown.

Elements in the Items collection can be of any type. The elements' text representation is specified by their ToString() methods.

Note

The editor's items must be unique objects.

When an end-user selects a row in the dropdown, the editor assigns a corresponding item from the Items collection to the ComboBoxEdit.SelectedItem property.

To select a specific item, you can use the following approaches:

At design time, you can populate the Items collection with string elements in the Visual Studio Property Grid. Other item types can only be added in code.

Expanded Example

The following code creates a combo box editor and adds three items to the item collection. Each item in the example is a PersonInfo class object, which stores a person's first and last names.

The ComboBoxItemCollection.BeginUpdate and ComboBoxItemCollection.EndUpdate methods are called to prevent excessive updates when the item collection is changed (three items are added).

The BaseListBoxControl.SelectedIndex property is set to -1 for demonstration purposes (the property is set to -1 by default). This ensures that no item is currently selected in the combo box.
