LayoutItemDragController Class

Contains methods to move a layout item to a position next to another layout item.

Namespace: DevExpress.XtraLayout.Customization

Assembly: DevExpress.XtraLayout.v20.1.dll

Declaration

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.

Examples

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:

LayoutItem_Move_ex_before

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

LayoutItem_Move_ex_after

using DevExpress.XtraLayout.Utils;
using DevExpress.XtraLayout.Customization;

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