| RepositoryItemCollection |
A RepositoryItemCollection object that contains a collection of repository items.
|
The Items property returns the object that provides methods to add, remove and access items within the current persistent repository.
Each item in the RepositoryItemCollection is represented by a particular RepositoryItem class descendant.
The following example uses a PersistentRepository to reuse a single repository item in a Data Grid and a Tree List.
using DevExpress.XtraEditors;
using DevExpress.XtraEditors.Repository;
public partial class Form1 : XtraForm {
public Form1() {
InitializeComponent();
// Create a persistent repository
PersistentRepository rep = new PersistentRepository();
//Add a repository item to the persistent repository
RepositoryItemSpinEdit spin = new RepositoryItemSpinEdit();
rep.Items.Add(spin);
//Link the persistent repository to controls
gridControl1.ExternalRepository = rep;
treeList1.ExternalRepository = rep;
// Assign the repository item to columns
gridView1.Columns["Id"].ColumnEdit = spin;
treeList1.Columns["Id"].ColumnEdit = spin;
}
}
