The DataView provides different views of the data stored in a DataTable. DataView can be used to sort, filter, and search data in a DataTable , additionally we can add new rows and modify the content in a DataTable. A DataView enables you to create different views of the data stored in a DataTable , a capability that is often used in data-binding applications.
A DataView provides a dynamic view of data in the underlying DataTable: the content, ordering, and membership reflect changes as they occur. Also we can delete the data from the DataView . The following C# source code shows how to delete the data from DataView.
using System;
using System.Data;
using System.Data.SqlClient;
using System.Windows.Forms;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string connetionString = null;
SqlConnection connection ;
SqlCommand command ;
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds = new DataSet();
DataView dv ;
string sql = null;
connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password";
sql = "Select * from product";
connection = new SqlConnection(connetionString);
try
{
connection.Open();
command = new SqlCommand(sql, connection);
adapter.SelectCommand = command;
adapter.Fill(ds, "Delete Row");
adapter.Dispose();
command.Dispose();
connection.Close();
dv = new DataView(ds.Tables[0], "", "Product_ID", DataViewRowState.CurrentRows);
dv.Table.Rows[3].Delete();
dataGridView1.DataSource = dv;
}
catch (Exception ex)
{
MessageBox.Show (ex.ToString());
}
