Rowcount And SQLDataReader

Hi, from what I can find, there isn't a way to get the number of rows returned from a SQLDataReader command. Is this correct? If so, is there a way around this? My SQLDataReader command is as follows:
Dim commandInd As New System.Data.OleDb.OleDbDataAdapter(strQueryCombined, connInd)
Dim commandSQL As New SqlCommand("GetAssetList2", connStringSQL)
Dim resultDS As New Data.DataSet()
'// Fill the dataset with values
commandInd.Fill(resultDS)
'// Get the XML values of the dataset to send to SQL server and run a new query
Dim strXML As String = resultDS.GetXml()
Dim xmlFileList As SqlParameter
Dim strContainsClause As SqlParameter
'// Create and execute the search against SQL Server
connStringSQL.Open()
commandSQL.CommandType = Data.CommandType.StoredProcedure
commandSQL.Parameters.Add("@xmlFileList", Data.SqlDbType.VarChar, 1000).Value = strXML
commandSQL.Parameters.Add("@strContainsClause", Data.SqlDbType.VarChar, 1000).Value = strContainsConstruct
Dim sqlReaderSource As SqlDataReader = commandSQL.ExecuteReader()
results.DataSource = sqlReaderSource
results.DataBind()
connStringSQL.Close()
And the stored procedure is such:
DROP PROC dbo.GetAssetList2;
GO
CREATE PROC dbo.GetAssetList2
(
@xmlFileList varchar(1000),
@strContainsClause varchar(1000)
)
AS
BEGIN
SET NOCOUNT ON
DECLARE @intDocHandle int
EXEC sp_xml_preparedocument @intDocHandle OUTPUT, @xmlFileList
SELECT DISTINCT
AssetsMaster.AssetMasterUID,
SupportedFiles.AssetPath,
FROM
AssetsMaster,
OPENXML (@intDocHandle, '/NewDataSet/Table',2) WITH (FILENAME varchar(256)) AS x,
SupportedFiles
WHERE
AssetsMaster.AssetFileName = x.FILENAME
AND AssetsMaster.Extension = SupportedFiles.Extension
 
UNION
SELECT DISTINCT
AssetsMaster.AssetMasterUID,
SupportedFiles.AssetPath,
FROM
AssetsMaster,
OPENXML (@intDocHandle, '/NewDataSet/Table',2) WITH (FILENAME varchar(256)) AS x,
SupportedFiles
WHERE
AssetsMaster.AssetFileName <> x.FILENAME
AND CONTAINS ((Description, Keywords), @strContainsClause)
AND AssetsMaster.Extension = SupportedFiles.Extension
ORDER BY AssetsMaster.Downloads DESC
EXEC sp_xml_removedocument @intDocHandle
END
GO
How can I access the number of rows returned by this stored procedure?
Thanks,
James
