Question : RDLC REPORT WITH PARAMETERS

I am using winforms on Visual Studio 2008, I have a report rdlc which get the data from a dataset
using the following query
SELECT     LABEL, SELLBY, PRICE, TARE, PLU, CODE, DATE
FROM         BIZERBA
GROUP BY LABEL, SELLBY, PRICE, TARE, PLU, CODE, DATE
HAVING      (DATE = ?)

I want to have a textbox on the form which I want to type the Date on the following format
12/24/2009 or any other date  then use this value for the report as a parameter based on the DATE field
I know I need to declare this under the form load, but I am having the difficulty doing this. Any code samples will be help . Thanks

Answer : RDLC REPORT WITH PARAMETERS

Do both solutions still raise the error "string was not recognized as a valid date time"?
