Example

[C#]

private void btnBack_Click(object sender, System.EventArgs e) 
{ 
    arv.ReportViewer.History.MovePrev(); 
    btnBack.Enabled = (arv.ReportViewer.History.Position >= 0); 
    btnForward.Enabled = (arv.ReportViewer.History.Position < arv.ReportViewer.History.Count); 
} 
 
private void btnForward_Click(object sender, System.EventArgs e) 
{ 
    arv.ReportViewer.History.MoveNext(); 
    btnBack.Enabled = (arv.ReportViewer.History.Position >= 0); 
    btnForward.Enabled = (arv.ReportViewer.History.Position < arv.ReportViewer.History.Count); 
} 
 
private void btnClear_Click(object sender, System.EventArgs e) 
{ 
    arv.ReportViewer.History.Clear(); 
    btnBack.Enabled = false; 
    btnForward.Enabled = false; 
}
