UserControl Constructor ()


Initializes a new instance of the UserControl class.

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


You do not typically create an instance of UserControl. To create your own user control class, inherit from the UserControl class.

The following code example creates an instance of the UserControl derived class, MyCustomerInfoUserControl, which was created in the example section of the UserControl class overview. The user control is added to a Panel control and has its Dock property set to DockStyle::Fill. The Panel is then added to a Form.

public ref class MyUserControlHost: public System::Windows::Forms::Form

   // Create the controls.
   System::ComponentModel::IContainer^ components;
   System::Windows::Forms::Panel^ panel1;
   UserControls::MyCustomerInfoUserControl^ myUserControl;


   // Define the constructor.


   // Add a Panel control to a Form and host the UserControl in the Panel.
   void InitializeComponent()
      components = gcnew System::ComponentModel::Container;
      panel1 = gcnew System::Windows::Forms::Panel;
      myUserControl = gcnew UserControls::MyCustomerInfoUserControl;

      // Set the DockStyle of the UserControl to Fill.
      myUserControl->Dock = System::Windows::Forms::DockStyle::Fill;

      // Make the Panel the same size as the UserControl and give it a border.
      panel1->BorderStyle = System::Windows::Forms::BorderStyle::FixedSingle;
      panel1->Size = myUserControl->Size;
      panel1->Location = System::Drawing::Point( 5, 5 );

      // Add the user control to the Panel.
      panel1->Controls->Add( myUserControl );

      // Size the Form to accommodate the Panel.
      this->ClientSize = System::Drawing::Size( panel1->Size.Width + 10, panel1->Size.Height + 10 );
      this->Text = "Please enter the information below...";

      // Add the Panel to the Form.
      this->Controls->Add( panel1 );
// End Class

int main()
   System::Windows::Forms::Application::Run( gcnew MyUserControlHost );
