ToolBar.ToolBarButtonCollection.Clear Method

Removes all buttons from the toolbar button collection.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public void Clear()

Implements

IList.Clear()

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.

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());
 }
