Its our old friend again…..
I am recieving this error and i cant think why. I have checked the number of parameters being passed as well as the number of required paramaters from the sp ,regenerating the data set has given me no look. I must have missed something basic. Another pair of eyes would be helpfull.

Thank you in advance 

    Public Sub GetRows(ByVal [Option] As String, ByVal searchString As String)

    Me.DataSet11.Clear()

    SqlSelectCommand1.CommandType = CommandType.StoredProcedure
    SqlSelectCommand1.Parameters.AddWithValue("@Option", [Option])
    SqlSelectCommand1.Parameters.AddWithValue("@searchString", searchString.ToUpper)

    Try
        SqlConnection1.Open()
        'execute reader
        'rdr = SqlSelectCommand1.ExecuteReader
        Me.DataGridViewAvItems.DataSource = DataSet11.design_sp_search_drawings
        Me.SqlDataAdapter1.Fill(DataSet11, "design_sp_search_drawing")

    Catch ex As Exception
        MessageBox.Show(ex.Message)
    Finally
        'close the conenction
        SqlConnection1.Close()
    End Try

End Sub

///DESIGNER CODE

Me.SqlSelectCommand1.CommandText = "dbo.design_sp_search_drawings"
    Me.SqlSelectCommand1.CommandType = System.Data.CommandType.StoredProcedure
    Me.SqlSelectCommand1.Connection = Me.SqlConnection1
    Me.SqlSelectCommand1.Parameters.AddRange(New System.Data.SqlClient.SqlParameter() {New System.Data.SqlClient.SqlParameter("@RETURN_VALUE", System.Data.SqlDbType.Int, 4, System.Data.ParameterDirection.ReturnValue, False, CType(0, Byte), CType(0, Byte), "", System.Data.DataRowVersion.Current, Nothing), New System.Data.SqlClient.SqlParameter("@searchString", System.Data.SqlDbType.VarChar, 20, System.Data.ParameterDirection.Input, False, CType(0, Byte), CType(0, Byte), "", System.Data.DataRowVersion.Current, "TES0201"), New System.Data.SqlClient.SqlParameter("@Option", System.Data.SqlDbType.VarChar, 20, System.Data.ParameterDirection.Input, False, CType(0, Byte), CType(0, Byte), "", System.Data.DataRowVersion.Current, "site_code")})

    Aren’t you adding the Option and SearchString parameters more than once? In the designer code you showed at the bottom, you add the parameters @RETURN_VALUE, @searchString, and @Option with the call to AddRange and you are adding them again at the top of the code when you call AddWithValue for each one of them. So to me it looks as if you have added 5 parameters. Am I missing something? What does the sproc require?
