I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.

On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value.
Then if user will provide some other telephone number then he allows to insert record.
For insertion of record I used ObjectdataSource.
User will enter telephone number in a simple textbox.
I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit.

I'm just stuck as I can't work out the best way to do it,
During an adaption of a book based example application, to use an access database instead of sql server - I have come up with the final issue: It will not insert into the database! I suspect it might be to do with the OrderID, I do have it set to autonumber,but I am not too sure. This is the class that does the inserts, by adding customer information to customer table, order information to order table and ordeitems information to the orderitems table. When submitting this information on the webpage, there is the custom error that an error has occurred in your order due to this code page code behind
bool success = OrderDB.WriteOrder(order);
Session["cart"] = null;
Session["order"] = null;
if (success)

Getting the message that ObjectDataSource ... count not find a non-generic method ... that has parameters ... The parameter list is fine until I get to the very end and it list the two data fields that are in my DetailsView. Using the ASP Tutorial #17 (Examining the Events Associated with Inserting, Updating, and Deleting) and the Exploring the Data Modification - specifically the one showing the INSERT of the Product Name and UnitPrice. ASPX page is pretty simple and attempting something similar, two fields to insert a new record - update the other fields later.
Full Error Message follows along with ASPX and the AsignaturasBLL.cs. Interesting thing is that when I swap the two fields in the DetailView, then the last two fields in the error message are swapped. In the error message I bolded these two fields.

I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?
