Property Value

Type: System.Int32

The number of the ToolBarButton controls assigned to the toolbar.

The Count property holds the actual number of ToolBarButton controls assigned to the collection. It is common to use the Count property value as the upper bounds of a loop to iterate through a collection. The index value of a collection is a zero-based index, so you must subtract one from the looping variable otherwise you will exceed the upper bounds of the collection and throw an exception.

The following code example displays the Count of the Buttons before and after the Clear method is called. This code requires that a ToolBar with at least one ToolBarButton has been created.

public void ClearMyToolBar()
    int btns;
    // Get the count before the Clear method is called.
    btns = toolBar1.Buttons.Count;
    MessageBox.Show("Count Before Clear: " + btns.ToString() +
                    "\nCount After Clear: " + toolBar1.Buttons.Count.ToString());
