Examples

The following code example creates a TabControl with two TabPage objects. To define the dimensions of the tabs, set the ItemSize property equal to a Size structure. In this example, Size defines the tabs 90 pixels wide and 50 pixels high. You cannot change the width of the tabs unless the SizeMode property is set to the Fixed value.

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

public:
   Form1()
   {
      this->tabControl1 = gcnew TabControl;
      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      
      // Sizes the tabs of tabControl1.
      this->tabControl1->ItemSize = System::Drawing::Size( 90, 50 );
      
      // Makes the tab width definable. 
      this->tabControl1->SizeMode = TabSizeMode::Fixed;
      array<Control^>^tabControl1Controls = {tabPage1,tabPage2};
      this->tabControl1->Controls->AddRange( tabControl1Controls );
      this->tabControl1->Location = Point(35,25);
      this->tabControl1->Size = System::Drawing::Size( 220, 220 );
      this->Size = System::Drawing::Size( 300, 300 );
      this->Controls->Add( tabControl1 );
   }

};

   Application::Run( gcnew Form1 );

        this.tabPage2 = new TabPage();
        
        // Sizes the tabs of tabControl1.
        this.tabControl1.ItemSize = new Size(90, 50);

        // Makes the tab width definable. 
        this.tabControl1.SizeMode = TabSizeMode.Fixed;

        this.tabControl1.Controls.AddRange(new Control[] {
            tabPage1, tabPage2});
        this.tabControl1.Location = new Point(35, 25);
