GridView Constructor

Initializes a new instance of the GridView class.

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

public GridView()

Use this constructor to initialize a new instance of the GridView class. To dynamically add a GridView control to a page, create a new GridView object, set its properties, and then add it to the Control.Controls collection of a container control, such as PlaceHolder.

The following example demonstrates how to use the constructor to dynamically add a GridView control to a page.


<%@ Page language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">

    void Page_Load(Object sender, EventArgs e)
    {

        // Create a new GridView object.
        GridView customersGridView = new GridView();

        // Set the GridView object's properties.
        customersGridView.ID = "CustomersGridView";
        customersGridView.DataSourceID = "CustomersSource";
        customersGridView.AutoGenerateColumns = true;

        // Add the GridView object to the Controls collection
        // of the PlaceHolder control.
        GridViewPlaceHolder.Controls.Add(customersGridView);

    }

</script>
