DomainUpDown.Wrap Property

Gets or sets a value indicating whether the collection of items continues to the first or last item if the user continues past the end of the list.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

[LocalizableAttribute(true)] 
public bool Wrap { get; set; }
/** @property */
public boolean get_Wrap ()

/** @property */
public void set_Wrap (boolean value)

public function get Wrap () : boolean

public function set Wrap (value : boolean)

Property Value

true if the list starts again when the user reaches the beginning or end of the collection; otherwise, false. The default value is false.

When the Wrap property is set to true, if you reach the last item in the collection and continue, the list will start over with the first item and appear to be continuous. This behavior works in reverse as well.

The following code example creates and initializes a DomainUpDown control. The example allows you to set some of its properties and create a collection of strings for display in the spin box (also known as an up-down control). The code assumes that a TextBox, CheckBox, and Button have been instantiated on a form. The example also assumes that you have a member variable at the class level declared as a 32-bit signed integer named myCounter. You can enter a string in the text box and add it to the Items collection when the button is clicked. By clicking the check box, you can toggle the Sorted property and observe the difference in the collection of items in the spin box.

protected DomainUpDown domainUpDown1;

private void MySub()
 {
    // Create and initialize the DomainUpDown control.
    domainUpDown1 = new System.Windows.Forms.DomainUpDown();
    
    // Add the DomainUpDown control to the form.
    Controls.Add(domainUpDown1);
 }
 
 private void button1_Click(System.Object sender, 
                           System.EventArgs e)
 {   
    // Add the text box contents and initial location in the collection
    // to the DomainUpDown control.
    domainUpDown1.Items.Add((textBox1.Text.Trim()) + " - " + myCounter);
    
    // Increment the counter variable.
    myCounter = myCounter + 1;
 
    // Clear the TextBox.
    textBox1.Text = "";
 }
 
 private void checkBox1_Click(System.Object sender, 
                             System.EventArgs e)
 {
    // If Sorted is set to true, set it to false; 
    // otherwise set it to true.
    if (domainUpDown1.Sorted)
    {
       domainUpDown1.Sorted = false;
    }
    else

       domainUpDown1.Sorted = true;

    MessageBox.Show("SelectedIndex: " + domainUpDown1.SelectedIndex.ToString() 
       + "\n" + "SelectedItem: " + domainUpDown1.SelectedItem.ToString());

    // Clear the TextBox.

    // If Sorted is set to true, set it to false; 
    // otherwise set it to true.
