SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnStudent_db"].ConnectionString);

<configuration>

<connectionStrings>

<add name="ConnStudent_db" connectionString="Data Source=.; Initial catalog=Student_db; Uid=sa; Pwd=anita" providerName="System.Data.SqlClient"/>

GridViewRow row = (sender as Button).Parent.Parent as GridViewRow;

HiddenField hdf = (HiddenField)row.FindControl("hdnStdid");

hdnStdid1.Value = hdf.Value;

txtRoll.Text = row.Cells[0].Text;

txtName.Text = row.Cells[1].Text;

}

protected void btnUpdate_Click(object sender, EventArgs e)

{

int roll = Convert.ToInt32(txtRoll.Text);

string name = txtName.Text;

SqlDataAdapter adp = new SqlDataAdapter("UPDATE STUD SET ROLL=" + roll + ",NAME='" + name + "' WHERE STDID=" + hdnStdid1.Value + "", con);
