protected void Button1_Click(object sender, EventArgs e) 
{ 
GridView1.Visible = true; 
DataTable dt = new DataTable(); 
DataRow row = dt.NewRow(); 
for (int i = 0; i < GridView1.Rows.Count; i++) 
{ 
TextBox txtUsrId=(TextBox)GridView1.Rows[i].FindControl("Your textbox id"); 
string UserID = txtUsrId.Text; 
string q="insert into details (name) values('"+UserID+"')"; 
SqlCommand cmd = new SqlCommand(q, con); 
SqlDataAdapter da = new SqlDataAdapter(cmd); 
da.Fill(dt); 
} 
}
