Problem with stored procedure

[Guest]

I am trying to query two tables with a stored procedure but I get the
following error:

"Procedure Details has no parameters and arguments were supplied."

Here is my stored procedure as created by Visual Studio:

ALTER PROCEDURE dbo.Details
AS
SET NOCOUNT ON;
SELECT Events.KeyID, Events.StartDate, Events.StartTime, Events.EventName,
Events.StartLocation, Events.EndLocation, Events.AvailableSeats,
Events.Description, Events.RateAdult, Events.RateChild, Events.RateSenior,
Reservations.KeyID AS Expr1, Reservations.EventID, Reservations.AccountID,
Reservations.qntyChild, Reservations.qntyAdult, Reservations.qntySenior,
Reservations.GroupID, Reservations.Status FROM Events INNER JOIN Reservations
ON Events.KeyID = Reservations.EventID

Here is the code being used to query the Stored Procedure in the page_load
event:

int EventID = Convert.ToInt32(Request.QueryString["ID"]);

this.sqlSelectCommand1.CommandText = "Details";
this.sqlSelectCommand1.CommandType = System.Data.CommandType.StoredProcedure;
this.sqlSelectCommand1.Connection = this.sqlConnection2;
this.sqlSelectCommand1.Parameters.Add(new
System.Data.SqlClient.SqlParameter("@EventID", System.Data.SqlDbType.Int, 4,
System.Data.ParameterDirection.ReturnValue, false, ((System.Byte)(0)),
((System.Byte)(0)), "", System.Data.DataRowVersion.Current, null));

this.sqlSelectCommand1.Parameters.Add("@EventID",
System.Data.SqlDbType.NVarChar).Value = EventID;

sqlConnection2.Open();
myReader = sqlSelectCommand1.ExecuteReader();

if (myReader.Read())
{
txtEventName.Text = myReader["EventName"].ToString();
}
sqlConnection2.Close();

Any ideas on why this isn't working?

This is my first time using a stored procedure in a project so any help
would be great.

Thanks, Justin.

You're stored procedure doesn't have a parameter and in your code you specify
a parameter. The stored procedure must begin like:

ALTER PROCEDURE dbo.Details
@EventID int
as begin
.......

and in the where clause:
where Reservations.EventID = @EventID

The code looks something like:
SqlParameter sqlPar = new SqlParameter("@EventID", SqlDbType.Int);
sqlPar.Value = EventID;
this.SelectCommand1.Parameters.Add(sqlPar);
