Gets the collection of objects assigned to the up-down control.
[Visual Basic] Public ReadOnly Property Items As DomainUpDown.DomainUpDownItems [C#] public DomainUpDown.DomainUpDownItems Items {get;} [C++] public: __property DomainUpDown.DomainUpDownItems* get_Items(); [JScript] public function get Items() : DomainUpDown.DomainUpDownItems;
A System.WinForms.DomainUpDownItems object that contains an Object collection.
The Object collection may be made available to the DomainUpDown control in two ways. If you have an array of objects that you have previously created in code, you can set the System.WinForms.DomainUpDownItems.All property equal to the array. Alternatively, you can add them one at a time by using the System.DomainUpDownItems.Add method.
The following example instantiates 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 up-down control. The code assumes that a Label, TextBox, CheckBox and a Button have been instantiated on a form. You can enter a string in the text box and add it to the System.WinForms.DomainUpDownItems.Items collection when the button is clicked. By clicking the check box, you can toggle the Sorted property and observe the the difference in the collection of items in the up-down control.
[Visual Basic]
' Instantiate the DomainUpDown control. Private DomainUpDown1 As System.WinForms.DomainUpDown Private myCounter as Integer Private Sub MySub() ' Initialize the DomainUpDown control. Form1.DomainUpDown1 = New System.WinForms.DomainUpDown End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) ' Add the text box contents to the DomainUpDown control and ' and its initial location in the collection. DomainUpDown1.Items.Add(Trim(TextBox1.Text) & " - " & myCounter) ' Increment the counter variable. myCounter = myCounter + 1 'Clear the TextBox. TextBox1.Text = "" End Sub Private Sub CheckBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) ' If Sorted is set to true, set it to false; otherwise set it to true. If DomainUpDown1.Sorted = True Then DomainUpDown1.Sorted = False Else DomainUpDown1.Sorted = True End If End Sub Private Sub DomainUpDown1_SelectedItemChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) ' Display the SelectedIndex & SelectedItem property values in the label. Label1.Text = "SelectedIndex: " & DomainUpDown1.SelectedIndex & vbcrlf & _ "SelectedItem: " & DomainUpDown1.SelectedItem End Sub
