Examples

The following code example removes the last ToolBarButton on a ToolBar. The index value of the toolbar button being removed is set equal to the Count property, minus one, since the ToolBarButton collection is a zero-based index.

public:
   void RemoveMyButton()
   {
      int btns;
      btns = toolBar1->Buttons->Count;
      
      // Remove the last toolbar button.
      toolBar1->Buttons->RemoveAt( btns - 1 );
   }

public void RemoveMyButton()
 {
    int btns;
    btns = toolBar1.Buttons.Count;
 
    // Remove the last toolbar button.
    toolBar1.Buttons.RemoveAt(btns - 1);
 }

Public Sub RemoveMyButton()
    Dim btns As Integer
    btns = toolBar1.Buttons.Count
    
    ' Remove the last toolbar button.
    toolBar1.Buttons.RemoveAt(btns - 1)
End Sub

Remarks

The Remove method removes the ToolBarButton at the specified location in the ToolBar.ToolBarButtonCollection. If you want to remove all ToolBarButton controls from the collection, use the Clear method.
