The datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.
EDIT:
Is there a way to create an empty/invisible object of the type in the LinqDataSource?

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction.

How do I add a parameter so that it includes the LIKE statement?
using vb.net/asp.net 2005 and SQL Server 2005 In my vb.net code I am setting the select statement for SqlDataSource1 and after that I am setting the DatasourceID for my gridview called grdGV (see below). However no rows are being displayed in the grid and the Rows.Count that I am printing out is 0. But when I taked the SqlDataSource1.SelectCommand printed out in my response.write statement below and query this in my SQL database I see 2 records being returned. So I am very puzzled why the database will return 2 records but the same exact query that is set in the SqlDataSource and then bound to the grid does not return 2 records?
I have also checked the DataSource.ConnectionString and it matches the database I am using.

I am trying to program the where prameters for this in code behind in C#, and is there really no way to do more than one parameter? Or am I not understanding this correctly? It seems only the 2nd parameter gets executed, no matter which one is at begining. I debug and seems they both get executed fine, but my listview doesn't get filtered and instead only the 2nd paramter works. Look at my code:
Also, if I do myLinq.Where = "division ==1 and someotherInt = 2", it works fine, but if I do two different data types, it will throw error. Since I want to filter with two different data types, hwo do I do this?
Parameter pram1 = new Parameter();
pram1.Name = "division";
pram1.DbType = DbType.Int32;
