[C++]
public: __property int get_RowCount();
[JScript]
public function get RowCount() : int;

Property Value

The number of rows that are currently being displayed in the tab strip.

Remarks

Use the RowCount property when the Multiline property is true and you want to know the number of rows that the tabs occupy.

Example

[Visual Basic, C#, C++] The following example creates a TabControl with five TabPage objects. This example uses the RowCount property to get the number of rows currently in the tabControl1 tab strip.

[Visual Basic, C#, C++] Use the System.Drawing and System.Windows.Forms namespaces for this example.
