Examples

The following example shows how to access properties of the DataPager control by using the Pager property in a handler for the TemplatePagerField.PagerCommand event. 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
