Namespace : DevExpress.XtraLayout.Customization

Assembly : DevExpress.XtraLayout.v25.2.dll

NuGet Package : DevExpress.Win.Navigation

Declaration

C#
VB.NET

public class LayoutItemDragController

Public Class LayoutItemDragController

Remarks

To move an item to a specific position, create a LayoutItemDragController object, initializing the item movement settings via the constructor’s parameters. The object’s settings should specify:

which item is to be moved.
the item next to which the first item is to be positioned.
the position at which the first item needs to be displayed.

After the settings have been initialized, call either the LayoutItemDragController.Drag method (if the item belongs to a LayoutControl) or the LayoutItemDragController.DragWildItem method (if the item doesn’t belong to a LayoutControl).

An alternative to the LayoutItemDragController.Drag method is the BaseLayoutItem.Move method overload, with a LayoutItemDragController object as a parameter.

Example

The following code shows how to move a layout item to a different position via code. An item is moved using the BaseLayoutItem.Move method.

Initially two layout items are displayed one under another:

In the example the second item is positioned on the right of the first layout item.

C#
VB.NET

using DevExpress.XtraLayout.Customization;

LayoutItemDragController dragController = new LayoutItemDragController(layoutControlItem2, 
  layoutControlItem1, MoveType.Inside, InsertLocation.After, LayoutType.Horizontal);
layoutControlItem2.Move(dragController);
