Hello together,

I want to add a order number, then add a material number with quantity.

Master, Detail with C#

OrderNumber = ………

Fill the list OrderNumbers

On right site I need a MaterialList

Input: Material = …….. Quantity = ……

     Add, Edit, Delete Button

Fille the list with MaterialNumbers and Quantity

Save it as XML.

Should be possible to reload it.

I'm looking for a good sample code.

Thanks in advance for your help!

Regards Markus

Hi Peter,
Workflow.
Start Application
Add new OrderNo with OrderName
Fill the list with material
Add next OrderNo and OrderName
Fill list with material
and so one.

Another application ask me about the material. Is material empty (processed) I go to the next order automatically.

Normally is to start the application with no order, empty.
Only in case the another application makes an error, we should reload the current state.

Maybe later I need to load the order and material list.
Like this --> Load OrdersVW.xml
Like this --> Load OrdersOpel.xml
and save as.

Order 1:n Material

How you solve it the same OrderNo? Can you show me the code?

On the edge. The forum takes getting used to.
Formatting and did I post? Code sequences.
I thought the old one was better. Maybe it'll be better here.

Hi Markus, in my last demo each "Add" generate a new OrderNumber:

case "AddOrder": int newOrderNumber = (this.col1.Count > 0) ? this.col1.Max((ord) => ord.OrderNumber) + 1 : 1;
