TabControl.TabPageCollection.Clear Method


Removes all the tab pages from the collection.

 virtual void Clear();
public virtual void Clear ();
abstract member Clear : unit -> unit
override this.Clear : unit -> unit
Public Overridable Sub Clear ()



The following code example initially creates a TabControl with three TabPage. This example uses the Clear method to clear all controls in the tabControl1 controls collection at one instance. Then, the example adds tabPage2 back to the collection. Notice that the TabPages property is used to get the tabControl1 controls collection to remove (and add) tab pages from this collection.

using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form
   TabControl^ tabControl1;
   TabPage^ tabPage1;
   TabPage^ tabPage2;
   TabPage^ tabPage3;

      this->tabControl1 = gcnew TabControl;
      this->tabPage1 = gcnew TabPage( "tabPage1" );
      this->tabPage2 = gcnew TabPage( "tabPage2" );
      this->tabPage3 = gcnew TabPage( "tabPage3" );
      // Populates the tabControl1 with three tab pages.
      array<TabPage^>^tabPages = {tabPage1,tabPage2,tabPage3};
      this->tabControl1->TabPages->AddRange( tabPages );
      // Removes all the tab pages from tabControl1.
      // Adds the tabPage1 back to tabControl1.
      this->tabControl1->TabPages->Add( tabPage2 );
      this->tabControl1->Location = Point(25,25);
      this->tabControl1->Size = System::Drawing::Size( 250, 250 );
      this->ClientSize = System::Drawing::Size( 300, 300 );
      this->Controls->Add( tabControl1 );
