TrackBar.Minimum Property

Gets or sets the lower limit of the range this TrackBar is working with.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public int Minimum { get; set; }

Property Value

Type: System.Int32
The minimum value for the TrackBar. The default is 0.

You can use the SetRange method to set both the Maximum and Minimum properties at the same time.

The following code example demonstrates how to use the TickFrequency, Minimum, and Maximum members and how to handle the ValueChanged event. To run the example, paste the following code into a form that contains a TrackBar control named TrackBar1 and a TextBox control named TextBox1. Call the InitializeTrackBar method from the form's constructor or Load event-handling method.


	//Declare a new TrackBar object. 
	internal System.Windows.Forms.TrackBar TrackBar1;

	// Initalize the TrackBar and add it to the form. 
	private void InitializeTrackBar()
	{
		this.TrackBar1 = new System.Windows.Forms.TrackBar();
		TrackBar1.Location = new System.Drawing.Point(75, 30);

		// Set the TickStyle property so there are ticks on both sides 
		// of the TrackBar.
		TrackBar1.TickStyle = TickStyle.Both;

		// Set the minimum and maximum number of ticks.
		TrackBar1.Minimum = 10;
		TrackBar1.Maximum = 100;

		// Set the tick frequency to one tick every ten units.
		TrackBar1.TickFrequency = 10;

		// Associate the event-handling method with the  
		// ValueChanged event.
		TrackBar1.ValueChanged += 
			new System.EventHandler(TrackBar1_ValueChanged);
		this.Controls.Add(this.TrackBar1);
	}
	

	// Handle the TrackBar.ValueChanged event by calculating a value for 
	// TextBox1 based on the TrackBar value.   
	private void TrackBar1_ValueChanged(object sender, System.EventArgs e)
	{
		TextBox1.Text = (System.Math.Round(TrackBar1.Value/10.0)).ToString();
	}
