GridView.RowCreated Event

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

Occurs when a row is created in a GridView control.

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

public event GridViewRowEventHandler RowCreated
/** @event */
public void add_RowCreated (GridViewRowEventHandler value)

/** @event */
public void remove_RowCreated (GridViewRowEventHandler value)

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

Before the GridView control can be rendered, a GridViewRow object must be created for each row in the control. The RowCreated event is raised when each row in the GridView control is created. This allows you to provide an event-handling method that performs a custom routine, such as adding custom content to a row, whenever this event occurs.

A GridViewRowEventArgs object is passed to the event-handling method, which allows you to access the properties of the row being created. To access a specific cell in the row, use the Cells property of the GridViewRowEventArgs object. You can determine which row type (header row, data row, and so on) is being created by using the RowType property.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to use the RowCreated event to store the index of the row being created in the CommandArgument property of a LinkButton control contained in the row. This allows you to determine the index of the row that contains the LinkButton control when the user clicked the button.

<script runat="server">

  void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
    // If multiple buttons are used in a GridView control, use the
    // CommandName property to determine which button was clicked.
      // Convert the row index stored in the CommandArgument
      // property to an Integer.
      int index = Convert.ToInt32(e.CommandArgument);
      // Retrieve the row that contains the button clicked 
      // by the user from the Rows collection.
      GridViewRow row = CustomersGridView.Rows[index];
      // Create a new ListItem object for the customer in the row.     
      ListItem item = new ListItem();
      item.Text = Server.HtmlDecode(row.Cells[2].Text);
      // If the customer is not already in the ListBox, add the ListItem 
      // object to the Items collection of the ListBox control. 
      if (!CustomersListBox.Items.Contains(item))

  void CustomersGridView_RowCreated(Object sender, GridViewRowEventArgs e)
    // The GridViewCommandEventArgs class does not contain a 
    // property that indicates which row's command button was
    // clicked. To identify which row's button was clicked, use 
    // the button's CommandArgument property by setting it to the 
    // row's index.
    if(e.Row.RowType == DataControlRowType.DataRow)
      // Retrieve the LinkButton control from the first column.
      LinkButton addButton = (LinkButton)e.Row.Cells[0].Controls[0];
      // Set the LinkButton's CommandArgument property with the
      // row's index.
      addButton.CommandArgument = e.Row.RowIndex.ToString();
