.NET Framework Class Library

FormView.ItemCreated Event

Note: This event is new in the .NET Framework version 2.0.

Occurs after all the rows are created in a FormView control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

Syntax

Visual Basic (Declaration)

Public Event ItemCreated As EventHandler

Visual Basic (Usage)

Dim instance As FormView
Dim handler As EventHandler

AddHandler instance.ItemCreated, handler

public event EventHandler ItemCreated

C++

public:
event EventHandler^ ItemCreated {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}

/** @event */
public void add_ItemCreated (EventHandler value)

/** @event */
public void remove_ItemCreated (EventHandler value)

JScript

JScript supports the use of events, but not the declaration of new ones.

Remarks

The ItemCreated event is raised after all rows are created in a FormView 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-handling method that performs a custom routine, such as adding to or modifying the contents of a row, whenever this event occurs.

Note
The ItemCreated event occurs before the FormView control is bound to data. To modify the value of a bound field, use the DataBound event.

You can access the header, footer, and pager rows in the FormView control by using the HeaderRow, FooterRow, TopPagerRow, or BottomPagerRow properties, respectively. To access the data row, use the Row property.

For more information about handling events, see Consuming Events.

Example

The following example demonstrates how to use the ItemCreated event to update the text of a Label control contained in the pager row.

Visual Basic

<%@ Page language="VB" %>

<script runat="server">

  Sub EmployeeFormView_DataBound(ByVal sender As Object, ByVal e As EventArgs)

    ' Get the pager row.
    Dim pagerRow As FormViewRow = EmployeeFormView.BottomPagerRow

    ' Get the Label controls that display the current page information 
    ' from the pager row.
    Dim pageNum As Label = CType(pagerRow.Cells(0).FindControl("PageNumberLabel"), Label)
    Dim totalNum As Label = CType(pagerRow.Cells(0).FindControl("TotalPagesLabel"), Label)

    If pageNum IsNot Nothing And totalNum IsNot Nothing Then

      ' Update the Label controls with the current page values.
      Dim page As Integer = EmployeeFormView.PageIndex + 1
      Dim count As Integer = EmployeeFormView.PageCount

      pageNum.Text = page.ToString()
      totalNum.Text = count.ToString()
    
    End If

  End Sub
    
</script>
