What is difference Between
protected void Page_Load(object sender, EventArgs e)
and
protected void btn_edit_Click(object sender, EventArgs e)
where as i declare a table through this code
adpt2 = new MySql.Data.MySqlClient.MySqlDataAdapter("select * from tbluser", cn);
adpt2.Fill(ds, "user");
in pageload function and after that i can used this table user can access in anywhere but when i declared this table within the btn_edit_click event that time i can't used this table outside this function. Why?
