次の例は、 TotalRowCountプロパティを使用して、ユーザーがListViewコントロールに存在しない項目を要求したかどうかを確認する方法を示しています。The following example shows how to use the TotalRowCount property to check whether the user requested an item that does not exist in the ListView control. このコード例は、 DataPagerCommandEventArgsクラスに対して提供される大規模な例の一部です。This code example is part of a larger example provided for the DataPagerCommandEventArgs class.

protected void TemplatePagerField_OnPagerCommand(object sender, DataPagerCommandEventArgs e)
{     
    // Get the new page number 
    TextBox PageNumberTextBox = (TextBox)e.Item.FindControl("PageNumberTextBox");
    int newPageNumber = -1;
    try
    {
      newPageNumber = Convert.ToInt32(PageNumberTextBox.Text.Trim());
    }
    catch (FormatException)
    {
      Message.Text = "Invalid page number.";
      return;
    }
    catch (OverflowException)
    {
      Message.Text = "Invalid page number.";
      return;
    }

    int newIndex = (newPageNumber - 1) * e.Item.Pager.PageSize;
    //Verify if the new index is valid
    if (newIndex >= 0 && newIndex <= e.TotalRowCount)
    {
      //Set the new start index and maximum rows
      e.NewStartRowIndex = newIndex;
      e.NewMaximumRows = e.Item.Pager.MaximumRows;
    }
    else
      Message.Text = "Invalid page number.";
}
Protected Sub TemplatePagerField_OnPagerCommand(ByVal sender As Object, _
  ByVal e As DataPagerCommandEventArgs)
  
  ' Get the new page number 
  Dim PageNumberTextBox As TextBox = _
    CType(e.Item.FindControl("PageNumberTextBox"), TextBox)
  
  Dim newPageNumber As Integer = -1
  Try
    newPageNumber = Convert.ToInt32(PageNumberTextBox.Text.Trim())
  Catch fex As FormatException
    Message.Text = "Invalid page number."
    Return
  Catch oex As OverflowException
    Message.Text = "Invalid page number."
    Return
  End Try
      
  Dim newIndex As Integer = _
    (newPageNumber - 1) * e.Item.Pager.PageSize
  
  'Verify if the new index is valid
  If newIndex >= 0 AndAlso newIndex <= e.TotalRowCount Then
    'Set the new start index and maximum rows
    e.NewStartRowIndex = newIndex
    e.NewMaximumRows = e.Item.Pager.MaximumRows
  Else
    Message.Text = "Invalid page number."
  End If
  
End Sub
