Namespace: DevExpress.XtraEditors.Repository

Assembly: DevExpress.XtraEditors.v19.2.dll

VB.NET

<DXCategory("Behavior")>
Public Property Middle As Integer

Property Value

Type	Description
Int32	An Int32 value that is the ZoomTrackBarControl value set to the middle tick.

Remarks

The Middle property specifies the value corresponding to the ZoomTrackBarControl‘s middle tick. This property allows you to divide a ZoomTrackBarControl’s total value range into two unequal value segments. The Middle property must lie between the RepositoryItemTrackBar.Minimum and RepositoryItemTrackBar.Maximum values.

For example, the Maximum property equals 20, the Minimum property equals 5 and the Middle property equals 7. This means it will take 2 steps to reach the middle starting from the beginning (from 5 to 7), and 13 additional steps to reach the end (from 7 to 20).

The RepositoryItemZoomTrackBar.AllowUseMiddleValue property specifies the Middle property’s availability. If this property equals false, the Middle property has no relevance and always equals 5.
