Remarks

Page view history is created as the user navigates from one page to another, similar to a browser's history. You can use MoveNext and MovePrev methods to traverse the page view history.

Example

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;
}

Visual Basic

Private Sub btnBack_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBack.Click
    With arv.ReportViewer.History
        .MovePrev()
        btnBack.Enabled = (.Position >= 0)

    End With
End Sub

        btnBack.Enabled = (.Position >= 0)
        btnForward.Enabled = (.Position < .Count)
    End With
End Sub
