Examples

The following code example creates a TabControl with four TabPage objects. The Multiline property is set to true, which displays two rows of tabs instead of one.

using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form
{
private:
   TabControl^ tabControl1;
   TabPage^ tabPage1;
   TabPage^ tabPage2;
   TabPage^ tabPage3;
   TabPage^ tabPage4;
   void MyTabs()
   {
      this->tabControl1 = gcnew TabControl;
      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      this->tabPage3 = gcnew TabPage;
      this->tabPage4 = gcnew TabPage;
      
      // Allows more than one row of tabs.
      this->tabControl1->Multiline = true;
      this->tabControl1->Padding = Point(22,5);
      array<Control^>^tabControls = {this->tabPage1,this->tabPage2,this->tabPage3,this->tabPage4};
      this->tabControl1->Controls->AddRange( tabControls );
      this->tabControl1->Location = Point(35,25);
      this->tabControl1->Size = System::Drawing::Size( 220, 220 );
      this->tabPage1->Text = "myTabPage1";
      this->tabPage2->Text = "myTabPage2";
      this->tabPage3->Text = "myTabPage3";
      this->tabPage4->Text = "myTabPage4";
      this->Size = System::Drawing::Size( 300, 300 );
      array<Control^>^formControls = {this->tabControl1};
      this->Controls->AddRange( formControls );
   }

End Class

Remarks

If Multiline is false, only one row of tabs is displayed, even if all the tabs do not fit in the available space. In that case, however, arrows are displayed that enable the user to navigate to the undisplayed tabs.

If the Multiline property is changed to false while the Alignment property is set to Left or Right, the Alignment property is automatically reset to Top.
