Examples

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;
      toolBar1->Buttons->Clear();
      MessageBox::Show( "Count Before Clear: " + btns.ToString() +
         "\nCount After Clear: " + toolBar1->Buttons->Count.ToString() );
   }

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

Public Sub ClearMyToolBar()
    Dim btns As Integer
    ' Get the count before the Clear method is called.
    btns = toolBar1.Buttons.Count
    toolBar1.Buttons.Clear()
    MessageBox.Show("Count Before Clear: " + btns.ToString() & _
        Microsoft.VisualBasic.ControlChars.Cr & "Count After Clear: " & _
        toolBar1.Buttons.Count.ToString())
End Sub

Remarks

The Clear method iterates through the collection and removes all toolbar buttons assigned to the ToolBar.ToolBarButtonCollection.

To remove an individual toolbar button from the collection, use the Remove or RemoveAt methods.

To add new ToolBarButton objects to the collection, use the Add, AddRange or Insert methods.
