Object created in one function, is null in an other function

Hey,

I would like to use the same Object in two functions. But somehow this object is null in the second function.

You first have to click on btnOrder and than you can see the btnConfirm. Because this btnConfirm is on a other panel, which is invisible at start.


Here's my code


private OrderBO order;
protected void btnOrder_Click(object sender, EventArgs e)
{
order= new OrderBO();
order.Adress = txtAdress.Text;
order.BookID = bookID;
order.City = txtWoonplaats.Text;
order.Count = Int32.Parse(txtCount.Text);
order.Date = DateTime.Now;
order.Email = txtEmail.Text;
order.Name = txtNaam.Text;
order.Pc = Int32.Parse(TxtPostcode.Text);

panelOrder.Visible = false;
panelConfirm.Visible = true;
}

protected void btnConfirm_Click(object sender, EventArgs e)
{
lblErrorInsert.Text = OrdersDAL.InsertOrder(order).ToString(); //Here is order null, why?
lblErrorInsert.Visible = true;
}


In the function btnBevestig_Click is the Object order null, I don't see why?

Is there perhaps some other code that could be responsible which you have not shown here?

For one thing, the global order is called "order," and in the confirm click, you are referencing ordersDAL, which I don't see ever being created in the code you posted....

Looking at this, I would guess that odersDAL is throwing the null reference exception, not order.

You can test by moving your instantiation outside of your method:

private OrderBO order = new OrderBO();

if you still get the null reference exception, you are not dealing with a null order.

I don't see why either, but it would help if you posted the code for the btnBevestig_Click method. Also, is this method called after the btnOrder_Click method?
