All grid action server side events

Here i am going to show you simple asp grid all inline editing with sorting. Like CRUD operation in MVP structure.

.cs Page code

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
        {
            GridView1.EditIndex = e.NewEditIndex; BindData();
        }

        protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {

            CurrentUserData = new Entity.UserData();
            CurrentUserData.UserId = Convert.ToInt64(GridView1.DataKeys[e.RowIndex].Value);
            _presenterData.GetCurrentData();
