Hi Mansoor After writing something in the textboxmove the cursor out of the textbox. Try this... Untitled Page ForeColor=Red Width=100px> ontextchanged=TextBox1_TextChanged> using System; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { string connStr = ConfigurationManager.ConnectionStrings[ConnectionString].ConnectionString; SqlDataAdapter ad = new SqlDataAdapter(); SqlCommand cmd = new SqlCommand(); SqlDataAdapter sqlda; DataSet ds; string str; protected void TextBox1_TextChanged(object sender EventArgs e) { SqlConnection conn = new SqlConnection(connStr); conn.Open(); str = select * from Contacts where name like ' + TextBox1.Text + %'; cmd = new SqlCommand(str conn); sqlda = new SqlDataAdapter(cmd); ds = new DataSet(); sqlda.Fill(ds Contacts); conn.Close(); GridView1.DataSource = ds; GridView1.DataMember = Contacts; GridView1.DataBind(); } } Thanks
