The indexed location within the collection to insert the toolbar button.

button
Type: System.Windows.Forms.ToolBarButton

The following code example removes an existing ToolBarButton from a ToolBar control if it exists and adds and inserts four new ToolBarButton objects to the ToolBar. This example requires that you have a Form with a ToolBar control on it.

private void AddToolbarButtons(ToolBar toolBar)
{
   if(!toolBar.Buttons.IsReadOnly)
   {
      // If toolBarButton1 in in the collection, remove it.
      if(toolBar.Buttons.Contains(toolBarButton1))
      {
         toolBar.Buttons.Remove(toolBarButton1);
      }

      // Create three toolbar buttons.
      ToolBarButton tbb1 = new ToolBarButton("tbb1");
      ToolBarButton tbb2 = new ToolBarButton("tbb2");
      ToolBarButton tbb3 = new ToolBarButton("tbb3");

      // Add toolbar buttons to the toolbar.		
      toolBar.Buttons.AddRange(new ToolBarButton[] {tbb2, tbb3});
      toolBar.Buttons.Add("tbb4");

      // Insert tbb1 into the first position in the collection.
      toolBar.Buttons.Insert(0, tbb1);
   }
}
