DomainUpDown Constructor ()
.NET Framework (current version)
Initializes a new instance of the DomainUpDown class.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
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 = gcnew System::Windows::Forms::DomainUpDown; // Add the DomainUpDown control to the form. Controls->Add( domainUpDown1 ); } 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( String::Concat( (textBox1->Text->Trim()), " - ", myCounter.ToString() ) ); // Increment the counter variable. myCounter = myCounter + 1; // Clear the TextBox. textBox1->Text = ""; } void checkBox1_Click( Object^ sender, 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; } } void domainUpDown1_SelectedItemChanged( Object^ sender, EventArgs^ e ) { // Display the SelectedIndex and SelectedItem property values in a MessageBox. MessageBox::Show( String::Concat( "SelectedIndex: ", domainUpDown1->SelectedIndex.ToString(), "\n", "SelectedItem: ", domainUpDown1->SelectedItem->ToString() ) ); }
