Exempel

I följande kodexempel skapas ett TabControl med två TabPage. Det här exemplet hämtar kontrollsamlingen tabControl1 och avgör om den är skrivskyddad med egenskapen IsReadOnly .

      Label^ label1 = gcnew Label;
      
      // Determines if the tabControl1 controls collection is read-only.
      if (tabControl1->TabPages->IsReadOnly)
            label1->Text = "The tabControl1 controls collection is read-only.";
      else
