Property Paths

You can access this nested property as listed below:

Library	Object Type	Path to AllowDelete
ASP.NET MVC Extensions	FileManagerSettings	.SettingsEditing .AllowDelete
ASP.NET Web Forms Controls	ASPxFileManager	.SettingsEditing .AllowDelete

Remarks

Use the AllowDelete property to control whether items can be deleted.

An end-user can copy a file manager item using the toolbar delete button or context menu Delete item, whose availability depends on the AllowDelete property value.

Toolbar Delete Button

The delete button is displayed in the toolbox if the FileManagerSettingsToolbar.Items collection contains an object of the FileManagerToolbarDeleteButton type. In this case, the AllowDelete property specifies the button’s availability.

When the FileManagerSettingsToolbar.Items collection is empty, the AllowDelete property specifies the copy button visibility.

Context Menu Delete Item

The delete item is displayed in the context menu if the FileManagerSettingsContextMenu.Items collection contains an object of the FileManagerToolbarDeleteButton type, or if the FileManagerSettingsContextMenu.Items collection is empty. The AllowDelete property specifies the item availability.
