May 5, 2010I have couple of DDL's which let user choose couple of different values from it. Once the user has made his selection he clicks on the "Submit" buttion which redirects the user to the other page, which then displays table from backend SQL DB. The pages are named Page1.aspx and Page2.aspx resp. I am using Querystring to carry forward the values of the DDL's to Page2.aspx.
How can i modify the query in such a way that even if one of the DDL's is left blank the Query would ignore that and shall produce the table considering value of DDL2 in the where clause. In case both the DDL's are empty then the query will not have a where clause and shall showcase the complete table as such. I've written a query for this but it's not working the way it shoul.Here is my code for the SQLDataSource: [Code]....

View 6 RepliesDataSource Controls :: EF Unable To Write Smalldatetime Date In SS2005 Table?
Jun 22, 2010Not a fan of creation and modifcation data in each table's row but I don't make the rules here. Something about normal comes to mind. Simple method to insert or update data in a table ia EF. Datatype = smalldatetime and no it is not changing across schema. Don't care about milli seconds. In oOrg = null I always fail because of a datatype mismatch.Not sure but didn't M$ make both of these products, and shouldn't the EF know about a smalldatetime when it reads the schema? So what is the fix outside of changing many tables to be datetime which is frowned upon at this piont.

ADO.NET :: How To Write A Query That Pulls Records From A Master Table
Mar 18, 2011Being new to Linq and Entity Framework, I find myself struggling to write queries that are relatively simple in SQL. My latest challenge is how to write a query that pulls records from a master table and includes a column for aggregating data from related detail records. Let's start with this example:
List<Customer> list = (from x in Customer select x.Customer_ID, x.CustomerName).ToList();
Now I'd like to modify this so that I include a column indicating how many orders each customer has, where there is a one-to-many relationship between the Customer and Order entities. I suspect the solution might result in a List of an anonymous type rather than the List of Customer like my example, but that would be
