Control::Controls Property

Gets the collection of controls contained within the control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
[BrowsableAttribute(false)]
public:
property Control..::.ControlCollection^ Controls {
	Control..::.ControlCollection^ get ();
}

Property Value

Type: System.Windows.Forms::Control::ControlCollection
A Control::ControlCollection representing the collection of controls contained within the control.

A Control can act as a parent to a collection of controls. For example, when several controls are added to a Form, each of the controls is a member of the Control::ControlCollection assigned to the Controls property of the form, which is derived from the Control class.

You can manipulate the controls in the Control::ControlCollection assigned to the Controls property by using the methods available in the Control::ControlCollection class.

When adding several controls to a parent control, it is recommended that you call the SuspendLayout method before initializing the controls to be added. After adding the controls to the parent control, call the ResumeLayout method. Doing so will increase the performance of applications with many controls.

Use the Controls property to iterate through all controls of a form, including nested controls. Use the GetNextControl method to retrieve the previous or next child control in the tab order. Use the ActiveControl property to get or set the active control of a container control.

The following code example removes a Control from the Control::ControlCollection of the derived class Panel if it is a member of the collection. The example requires that you have created a Panel, a Button, and at least one RadioButton control on a Form. The RadioButton control(s) are added to the Panel control, and the Panel control added to the Form. When the button is clicked, the radio button named removeButton is removed from the Control::ControlCollection.

   // Remove the RadioButton control if it exists. 
private:
   void removeButton_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      if ( panel1->Controls->Contains( removeButton ) )
      {
         panel1->Controls->Remove( removeButton );
      }
   }
