c# Order Processing ASP.NET Page
Question
I am building a ASP.NET page which is an Sales Order Processing Form I have two Last issues that due to my lack of experience in the language I am struggling with hopefully you can help.
Issue 1 - I have a field <asp:DropDownList runat="server" ID="txtProduct"></asp:DropDownList> that is pulling from a database table Called Products to populate its options list. I need to automatically pull the SalesPrice value and insert it into the txtUnitAmount field based on the selection of the Product.
Issue 2 - Once the form has been filled and there are records in the DataTable I then need to insert all of the rows into the Database table SalesOrders when a user clicks a button.

I think with a bit of help and guidance I will be done and ever so grateful this will also stand me in good sted for further projects, thanks in advance to everyone who answers I will of course give full props to everyone who helps out.
In the mean time a thank you to @Slappy, @Nick & @MikeEast and the other many who have been really helpful thus far.

As I can't write the entire code, so only giving you some hints.
1. Create a class with the field name you want to insert into you DB.
Like for Sales order, whatever fields you have in your form,
create properties for the same.
2. Bind the grid and Dropdowns from the database using the datatable.
3. Put a hidden field on the form to detect insert or update process
4. On selection chnage of grid or dropdown fill the form fields,
you have for sales order. By extracting the rows from the datatable
and fill it to textboxes.
5. While save button click , create a method that will be used for filling
up the SalesOrder Class object. pass this object to data layer, extract
the properties and pass it as parameter in your AddUpadte query.

which framework are you using? Dropdown list auto postback=true should be set, then create event SelectedIndex Change then write your code to auto fill the text post ( textboxName.text = dropdownlistName.selectedItem.Tex ).
Hope it helps:)
