hi try like this: it just a sample in aspx: ToolTip=Movie Details> in .cs: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Configuration; using System.Data.SqlClient; using System.Data; public partial class Default8 : System.Web.UI.Page { string connStr = ConfigurationManager.ConnectionStrings[ConStr].ToString(); protected void Page_Load(object sender EventArgs e) { bind(); } private void bind() { SqlConnection conn = new SqlConnection(connStr); SqlDataAdapter da = new SqlDataAdapter(Select * from Movie conn); DataSet ds = new DataSet(); da.Fill(ds); dgvMovie.DataSource=ds.Tables[0]; dgvMovie.DataBind(); } protected void btnSubmit_Click(object sender EventArgs e) { bind(); } } here i create a separate method for gird binding and call in page load and button click so it will bind the record when you submit.

Hi First check weather data is getting saved or not in your database. And put the below code in page load protected void Page_Load(object sender EventArgs e) { dgvMovie.DataBind(); } Regards Iftikar

I think you want to do search on button click. Provide your sql query for binding data to gridview. Regards Iftikar
