Initializes a new instance of the PictureBox class.

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

public PictureBox()

The following table shows initial property values for an instance of the PictureBox class.

Item

Description

Image

null

SizeMode

Normal

The following code example demonstrates the use of the PictureBox and ListView controls. The PictureBox is initialized by setting the BorderStyle and SizeMode properties using the BorderStyle and PictureBoxSizeMode enumerations, respectively. The ListView is populated with pictures from the Sample Pictures directory. The ListView.GetItemAt method is used when handling the MouseDown event of the ListView control to determine whether an item is selected. If an item is selected, the event handler displays the selected file by setting the Image property. The example requires that you have JPG files located in the C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures directory. To run the example, paste the code into a form and call the InitializePictureBox and PopulateListView methods in the form's constructor or Load event-handling method. Ensure all events are associated with their event-handling methods.

	private void PopulateListView()
	{
		ListView1.Width = 270;
		ListView1.Location = new System.Drawing.Point(10, 10);

		// Declare and construct the ColumnHeader objects.
		ColumnHeader header1, header2;
		header1 = new ColumnHeader();
		header2 = new ColumnHeader();

		// Set the text, alignment and width for each column header.
		header1.Text = "File name";
		header1.TextAlign = HorizontalAlignment.Left;
		header1.Width = 70;

		header2.TextAlign = HorizontalAlignment.Left;
		header2.Text = "Location";
		header2.Width = 200;

		// Add the headers to the ListView control.
		ListView1.Columns.Add(header1);
		ListView1.Columns.Add(header2);

        // Specify that each item appears on a separate line.
        ListView1.View = View.Details;

        // Populate the ListView.Items property. 
		// Set the directory to the sample picture directory.
		System.IO.DirectoryInfo dirInfo = 
			new System.IO.DirectoryInfo(
			"C:\\Documents and Settings\\All Users" +
			"\\Documents\\My Pictures\\Sample Pictures");
		

		// Get the .jpg files from the directory
		System.IO.FileInfo[] files = dirInfo.GetFiles("*.jpg");

		// Add each file name and full name including path 
		// to the ListView. 
		if (files != null)
		{
			foreach ( System.IO.FileInfo file in files )
			{
				ListViewItem item = new ListViewItem(file.Name);
				item.SubItems.Add(file.FullName);
				ListView1.Items.Add(item);
			}
		}
	}

	private void InitializePictureBox()
	{
		PictureBox1 = new PictureBox();

		// Set the location and size of the PictureBox control. 
		this.PictureBox1.Location = new System.Drawing.Point(70, 120);
		this.PictureBox1.Size = new System.Drawing.Size(140, 140);
		this.PictureBox1.TabStop = false;

		// Set the SizeMode property to the StretchImage value.  This 
		// will shrink or enlarge the image as needed to fit into 
		// the PictureBox. 
		this.PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;

		// Set the border style to a three-dimensional border. 
		this.PictureBox1.BorderStyle = BorderStyle.Fixed3D;

		// Add the PictureBox to the form. 
		this.Controls.Add(this.PictureBox1);

	}


	private void ListView1_MouseDown(object sender, MouseEventArgs e)
	{

		ListViewItem selection = ListView1.GetItemAt(e.X, e.Y);

		// If the user selects an item in the ListView, display 
		// the image in the PictureBox. 
		if (selection != null)
		{
			PictureBox1.Image = System.Drawing.Image.FromFile(
				selection.SubItems[1].Text);
		}
	}
