Can ObjectDataSource use table-valued parameters

If an ASP.NET web page uses an ObjectDataSource, can you configure it to use a stored procedure that uses table-value parameters?

User-defined type:

CREATE TYPE [dbo].[integer_list_tbltype] AS TABLE
(
 [n] [int] NOT NULL,
 PRIMARY KEY CLUSTERED 
)

Stored procedure:

CREATE PROCEDURE [dbo].[GeneralReport]  
@intList integer_list_tbltype READONLY
AS
BEGIN
    SELECT * FROM ...
END

ASP.NET

<asp:ObjectDataSource ID="GeneralDataSource" runat="server" 
    SelectMethod="GetDataByRange" 
    TypeName="MyProject.GeneralDataSetTableAdapters.GeneralViewTableAdapter" 
    >
    <SelectParameters>
        <asp:Parameter Name="intList" />            
    </SelectParameters>
</asp:ObjectDataSource>

I've tried hooking into the ObjectDataSource's Selecting event like this:

protected void GeneralDataSource_Selecting( object sender, System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs e )
{
    var zeroList = new List<SqlDataRecord>();
    var tvp_definition = new[] {new SqlMetaData( "n", SqlDbType.Int )};
    var sqlDataRecord = new SqlDataRecord( tvp_definition );
    sqlDataRecord.SetInt32( 0, 0 );

    zeroList.Add( sqlDataRecord  );

    e.InputParameters[ "intList" ] = zeroList;        
}

But that just results in a "System.ArgumentException: UdtTypeName property must b开发者_C百科e set for UDT parameters." being thrown

I do not know why you wish to do it this way. See this blog post by Lenni Lobel and see if that works for you.

*UPDATE:*For reporting I use this technique as shown on Codebetter.com

For the sake of completeness, this is a possible solution (though it probably does fall into the 'horrible' category!)

Override the table adapter that was generated by the strongly-typed dataset. eg.

public class GeneralViewTableAdapter2 : GeneralViewTableAdapter
{
    public override GeneralDataSet.GeneralViewDataTable GetDataByRange( object intList )
    {
        try
        {
            return base.GetDataByRange( intList );
        }
        catch ( ArgumentException e )
        {
            foreach ( SqlParameter parameter in this.Adapter.SelectCommand.Parameters )
            {
                if ( parameter.SqlDbType == SqlDbType.Structured )
                    parameter.TypeName = "integer_list_tbltype";
            }

            return base.GetDataByRange( intList );
        }
    }
}

Then update the Type attribute on the ObjectDataSource control to refer to this new class. eg. "MyProject.GeneralDataSetTableAdapters.GeneralViewTableAdapter2"

Would love to see a 'cleaner' answer than this!
