View 2 RepliesForms Data Controls :: Bind A GridView To A DataTable (in Viewstate) With Full In-line CRUD?
Sep 24, 2010I need a bit of help with a scenario. I am working on a web application that requires huge amounts of data to be Added, Deleted, and Updated. The data entry forms are divided into logical groups through Multiviews. All the information is saved when the mighty Finish button is pressed. The current setup (previous developer) does not allow me to use transactions. Therefore, if I am to save a new Courier to the database, I need to add his/her Distance and Rate info. In addition, I need to add his/her Banned Areas info (Area Name, Post Code).This is where it gets interesting. Obviously, the DistamceAndRate table and the BannedArea table in my SQL Server will have the CourierID as a foreign key. Since I'm going to save the Courier as well as the Rates and Areas info in one go, I cannot have the newly created CourierID before. Therefore, I cannot bind my Grids for Distance + Rates and Banned Areas directly to database.What I am doing is creating two DataTables and managing them in Viewstate through properties as follow:
[Code]....
So, on page load, the DataTables are initialized with a blank schema. Here are the attempted CRUD implementations (Distance and Rate only):
[Code]....
I am having issues when I am canceling a new entry and when I am editing a new entry. In addition, for Distance and Rates, Rate is acting as unique (cannot be repeated) and attempting to control that is also giving me a headache. I end up creating blank rows.And here's the ASPX cut-out:
[Code]....
Hope to get an answer soon.Also, off-topic, I'm using LINQ here. In order to save a Courier and his/her extra details, I first save his/her address to DB. Then I take the ID of the address and save the courier. now the courier ID is avaliable and i start filling extra tables related with the courier table. If something goes wrong, I have to manually delete created rows. LINQ uses transaction internally but only until a SubmitChanges() call. I'm forced to save each entity so I keep calling SubmitChanges().I tried manual transaction but after saving the address inside a transaction, the Address.OID (Address table's mapped prime-key) had a 0. attempting to use this newly added address while saving Courier in the same transaction threw an exception. If there is a way to get the primary key for entities created in a transaction that is yet to be commited, please mention that'll as well.
