Public Sub New()
	InitializeComponent()
	For Each ts As ToolStrip In crystalReportViewer1.Controls.OfType(Of ToolStrip)()
		For Each tsb As ToolStripButton In ts.Items.OfType(Of ToolStripButton)()
			'hacky but should work. you can probably figure out a better method
			If tsb.ToolTipText.ToLower().Contains("print") Then
				'Adding a handler for our propose
				tsb.Click += New EventHandler(AddressOf printButton_Click)
			End If
		Next
	Next
End Sub

Private Sub printButton_Click(sender As Object, e As EventArgs)
	MessageBox.Show("Printed")
End Sub

    public Form1()
    {
        InitializeComponent();
        foreach (ToolStrip ts in crystalReportViewer1.Controls.OfType<ToolStrip>())
        {
            foreach (ToolStripButton tsb in ts.Items.OfType<ToolStripButton>())
            {
                //hacky but should work. you can probably figure out a better method
                if (tsb.ToolTipText.ToLower().Contains("print"))
                {
                    //Adding a handler for our propose
                    tsb.Click += new EventHandler(printButton_Click);
                }
            }
