Introduction:
A DataView provides various views of the data stored in a DataTable. Using a DataView, you can expose the data in a table with different sort orders, and you can filter the data by row state or based on a filter expression. That is we can customize the views of data from a DataTable.
Example:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</div>
</form>
</body>
</html>
CS:
SqlConnection con = new SqlConnection("Data Source=.; uid=sa; pwd=wintellect;database=Rohatash;");
string strSQL = "Select * from UserDetail";
SqlDataAdapter dt = new SqlDataAdapter(strSQL, con);
DataSet ds = new DataSet();
dt.Fill(ds, "UserDetail");
con.Close();
DataView dv = new DataView();
GridView1.DataSource = ds.Tables[0].DefaultView;
GridView1.DataBind();
