Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v18.1.dll

Declaration

C#

[ToolboxTabName("DX.18.1: Common Controls")]
[ToolboxBitmap(typeof(ToolboxIconsRootNS), "ZoomTrackBarControl")]
public class ZoomTrackBarControl :
    TrackBarControl

VB.NET

<ToolboxBitmap(GetType(ToolboxIconsRootNS), "ZoomTrackBarControl")>
<ToolboxTabName("DX.18.1: Common Controls")>
Public Class ZoomTrackBarControl
    Inherits TrackBarControl

Remarks

The ZoomTrackBarControl is appropriate for creating zoom bars similar to the Zoom Bar control in MS Office applications. It represents a track bar with the ‘+’ and ‘-‘ buttons, clicking which moves the scroll thumb in the corresponding direction:

The control’s settings are specified by the ZoomTrackBarControl.Properties property, which returns an object of the RepositoryItemZoomTrackBar type.

Use the inherited RepositoryItemTrackBar.Minimum and RepositoryItemTrackBar.Maximum properties to set the scroll range. The scroll thumb’s current position is specified by the control’s TrackBarControl.Value property.
