Examples
The following code example creates a TabControl with two TabPage. This example gets the tabControl1
controls collection and determines if it is read-only using the IsReadOnly property.

using namespace System::Windows::Forms;
public ref class Form1: public Form

{
TabControl^ tabControl1 = gcnew TabControl;
TabPage^ tabPage1 = gcnew TabPage;
TabPage^ tabPage2 = gcnew TabPage;
Label^ label1 = gcnew Label;
// Determines if the tabControl1 controls collection is read-only.
if ( tabControl1->TabPages->IsReadOnly == true )
label1->Text = "The tabControl1 controls collection is read-only.";
else
label1->Text = "The tabControl1 controls collection is not read-only.";
array<TabPage^>^tabPages = {tabPage1,tabPage2};
tabControl1->TabPages->AddRange( tabPages );
tabControl1->Location = Point(25,75);
tabControl1->Size = System::Drawing::Size( 250, 200 );
label1->Location = Point(25,25);
label1->Size = System::Drawing::Size( 250, 25 );

}
};
