I see that basically you want to fill a datagrid, there are some cases where is needed to use a datareader, lets say that you want to interact with the values returned from the database and create your own custom table, but if you going to display the data as is, i will fill a dataset or datatable better.

'I see you have two instance one for the SqlConnection "CON" and SqlCommand "CMD"

Dim dt As New DataTable
CMD.CommandType = CommandType.StoredProcedure
CMD.CommandText = "DTAAGRID_FILL_STAFF"
CMD.Connection = CON
CMD.Parameters.Add("@STAFF_ID", SqlDbType.VarChar).Value = Convert.ToString(CboStaffNo.SelectedValue)
CMD.Parameters.Add("@START_TIME", SqlDbType.DateTime).Value = Convert.ToDateTime(DTPFromDate.Value)
CMD.Parameters.Add("@END_TIME", SqlDbType.DateTime).Value = Convert.ToDateTime(DTPToDate.Value)
Dim adapt As New SqlClient.SqlDataAdapter(CMD)
adapt.Fill(dt)
dgbStaffInfo.DataSource = dt

That error means that the your sending more parameters to the stored procedure that it supposed to received. just double check how many parameters do you have in your stored procedure.
