public DataPagerFieldItem Item { get; }

Property Value

Type: System.Web.UI.WebControls.DataPagerFieldItem
The DataPagerFieldItem object that contains the DataPagerField object and the DataPagerField object's container DataPager object.

The DataPagerField object, which is contained in the DataPagerFieldItem object returned by this property, contains the button that was clicked. Alternatively, you can use the PagerField property to retrieve the DataPagerField object.

The following example shows how to use the Item property to retrieve a TextBox control that is contained in the TemplatePagerField object. 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.";
}
