    • Syncfusion.Tools.Windows

  3. Include the required namespace.

​

using Syncfusion.Windows.Forms.Tools;
Imports Syncfusion.Windows.Forms.Tools
  1. Create an instance of TrackBarEx control, and add it to the window.

​

//Instance of TrackBarEx
   TrackBarEx trackBarEx1 = new TrackBarEx();
   trackBarEx1.Value = 5;
   this.Controls.Add(trackBarEx1);
'Instance of TrackBarEx
   Dim trackBarEx1 As TrackBarEx = New TrackBarEx
   trackBarEx1.Value = 5

Change value

You can define the minimum and maximum values by setting the Minimum and Maximum properties of TrackBarEx.

this.trackBarEx1.Minimum = 10;
this.trackBarEx1.Maximum = 30;
Me.trackBarEx1.Minimum = 10
Me.trackBarEx1.Maximum = 30

Horizontal or vertical track bar

The TrackBarEx control can be oriented horizontally or vertically using the Orientation property.

// To set the control to be vertically oriented.
this.trackBarEx1.Orientation = Orientation.Vertical;

// To set the control to be horizontally oriented.
this.trackBarEx1.Orientation = Orientation.Horizontal;
'To set the control to be vertically oriented.
Me.trackBarEx1.Orientation = Orientation.Vertical

'To set the control to be horizontally oriented.
Me.trackBarEx1.Orientation = Orientation.Horizontal
