Control::ControlCollection::RemoveAt Method

Removes a control from the control collection at the specified indexed location.

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

public:
virtual void RemoveAt(
	int index
) sealed

Parameters

index
Type: System::Int32

The index value of the Control to remove.

Implements

IList::RemoveAt(Int32)

When a Control is removed from the control collection, all subsequent controls are moved up one position in the collection.

You can also remove a Control that you previously added by using the Remove or Clear methods.

To add new Control objects to the collection, use the Add or AddRange methods.

The following code example removes the first Control in the Control::ControlCollection of the derived class Panel if the count of the collection is greater than zero. The example requires that you have created a Panel, a Button, and at least one other control on a Form. The other controls are added to the Panel control, and the Panel control added to the Form. When the button is clicked, the first control contained in the panel is removed from the Control::ControlCollection.

   // Remove the first control in the collection. 
private:
   void removeAtButton_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      if ( panel1->Controls->Count > 0 )
      {
         panel1->Controls->RemoveAt( 0 );
      }
   }
