ScrollBar.Minimum Property

Gets or sets the lower limit of values of the scrollable range.

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

public int Minimum { get; set; }

Property Value

Type: System.Int32
A numeric value. The default value is 0.

The following example assumes that you have created a Form, added a PictureBox to the Form, and added a horizontal HScrollBar and a vertical VScrollBar to the PictureBox. This code example is part of a larger example provided for the ScrollBar class overview.

In this example, the Minimum property is set to 0.

You must add references to the System.Drawing and System.Windows.Forms namespaces to run this example.

NoteNote

For instructions about how to run this example in Visual Studio, see How to: Compile and Run a Complete Windows Forms Code Example Using Visual Studio.

public void SetScrollBarValues()
{
    //Set the following scrollbar properties: 

    //Minimum: Set to 0 

    //SmallChange and LargeChange: Per UI guidelines, these must be set 
    //    relative to the size of the view that the user sees, not to 
    //    the total size including the unseen part.  In this example, 
    //    these must be set relative to the picture box, not to the image. 

    //Maximum: Calculate in steps: 
    //Step 1: The maximum to scroll is the size of the unseen part. 
    //Step 2: Add the size of visible scrollbars if necessary. 
    //Step 3: Add an adjustment factor of ScrollBar.LargeChange. 


    //Configure the horizontal scrollbar 
    //--------------------------------------------- 
    if (this.hScrollBar1.Visible)
    {
        this.hScrollBar1.Minimum = 0;
        this.hScrollBar1.SmallChange = this.pictureBox1.Width / 20;
        this.hScrollBar1.LargeChange = this.pictureBox1.Width / 10;

        this.hScrollBar1.Maximum = this.pictureBox1.Image.Size.Width - pictureBox1.ClientSize.Width;  //step 1 

        if (this.vScrollBar1.Visible) //step 2
        {
            this.hScrollBar1.Maximum += this.vScrollBar1.Width;
        }

        this.hScrollBar1.Maximum += this.hScrollBar1.LargeChange; //step 3
    }

    //Configure the vertical scrollbar 
    //--------------------------------------------- 
    if (this.vScrollBar1.Visible)
    {
        this.vScrollBar1.Minimum = 0;
        this.vScrollBar1.SmallChange = this.pictureBox1.Height / 20;
        this.vScrollBar1.LargeChange = this.pictureBox1.Height / 10;

        this.vScrollBar1.Maximum = this.pictureBox1.Image.Size.Height - pictureBox1.ClientSize.Height; //step 1 

        if (this.hScrollBar1.Visible) //step 2
        {
            this.vScrollBar1.Maximum += this.hScrollBar1.Height;
        }

        this.vScrollBar1.Maximum += this.vScrollBar1.LargeChange; //step 3
    }
