範例

下列程式碼範例會建立具有五 TabPage 個 TabControl 物件的 。 這個範例會 RowCount 使用 屬性來取得索引標籤帶中目前的資料 tabControl1 列數目。

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

      TabControl^ tabControl1 = gcnew TabControl;

      TabPage^ tabPage5 = gcnew TabPage;
      Label^ label1 = gcnew Label;
      
      // Allows multiple rows of tabs in the tabControl1 tab strip.
      tabControl1->Multiline = true;
      tabControl1->SizeMode = TabSizeMode::FillToRight;
      tabControl1->Padding = Point(15,5);

      // Assigns int value to the rows variable.
      int rows = tabControl1->RowCount;

備註

RowCount當 屬性是 true 且您想要知道索引標籤佔用的資料列數目時 Multiline ，請使用 屬性。
