DetailsView.ItemCreated Event

Occurs when a record is created in a DetailsView control.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)
public event EventHandler ItemCreated
<asp:DetailsView OnItemCreated="EventHandler" />

The ItemCreated event is raised each time a record is created in a DetailsView control. This can occur when the control is first rendered, or when the user navigates to another record. You can use this event to provide an event handler that performs a custom routine, such as adding custom content to a row, whenever this event occurs.

You can access the header, footer, and pager rows in the DetailsView control by using the HeaderRow, FooterRow, TopPagerRow, or BottomPagerRow properties, respectively. To access one of the data rows, use the Rows collection.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to use the ItemCreated event to update a custom pager row with current paging statistics.

  {

    // Get the header row.
      DetailsViewRow headerRow = CustomerDetailView.HeaderRow;

    // Get the Label control that displays the current page information 
    // from the header row.
    Label pageNum = (Label)headerRow.FindControl("PageNumberLabel");

    if(pageNum != null)
    {
      // Update the Label control with the current page number.
        int page = CustomerDetailView.DataItemIndex + 1;
      pageNum.Text = "Page " + page.ToString ();
    }
  }
