Examples

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

ASP.NET (C#) 

<%@ 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>

<html xmlns="http://www.w3.org/1999/xhtml" >
  <head runat="server">
    <title>GridView Constructor Example</title>
</head>
<body>
    <form id="form1" runat="server">

      <h3>GridView Constructor Example</h3>

      <asp:placeholder id="GridViewPlaceHolder"
        runat="Server"/>

      <!-- This example uses Microsoft SQL Server and connects  -->
      <!-- to the Northwind sample database. Use an ASP.NET     -->
      <!-- expression to retrieve the connection string value   -->
      <!-- from the Web.config file.                            -->
      <asp:sqldatasource id="CustomersSource"
        selectcommand="Select [CustomerID], [CompanyName], [City] From [Customers]"
        connectionstring="<%$ ConnectionStrings:NorthWindConnectionString%>" 
        runat="server"/>

    </form>
  </body>
</html>

Remarks

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.
