dont allow user to select existing date

12-Dec-12 4:33

Hey guys so atm when the user goes to the holiday page, they can do 1 of 2 things

1)use a drop down box to select 'person name' and click 'view' this will display all the current holidays for this person

2)click 'create new' which will bring the user to a create page which allows them to add a new holiday(from here they select person name from drop and and select what date from calender)

This all works, however if the user originally follows the first path of selecting a person name and clicking view(it will display their holidays) if they then take the path of 2 and click 'create' it will jump to the create page. however the drop down box will be back at 'select' i would like the existing person selected from the previous drop down to display in this drop down.

A cookie or url/parameter?

anyway Im stuck please help

I've tried a cookie.

So the user selects holidays (start and end dates) from two calendars, the dates from start to end are then stored in the DB in separate records per date.

(thanks to help from a previous question this all works fine)

Now, I want some sort of error message which doesnt allow the button to be clicked if the dates the user are selecting already exist in the DB.

Im unsure if this is done from the view, or controller?

View:

HTML

<form action ="ListHolidays" id="listHolidays" method="post">

                    db.SaveChanges();



                    //say start date is 10. AddDays(1) will make it 11 then return it to startDates in 'startDates' = startdates,
                    //but doesnt chage the value of startdates = 'startdates'
                }

                startDates = startDates.AddDays(1);
            }

            return RedirectToAction("Index");

so...? if holidayDate = db.exisitng date?

Unsure how to go about this.

Please advise.

thanks

I'd be tempted to use this logic:

JavaScript

$(function () {
//3 methods below dont allow user to select weekends
    $('.date-pick').datePicker(
       {
           createButton: false,
           renderCallback: function ($td, thisDate, month, year)
           {
               if (thisDate.isWeekend())
               {
                   $td.addClass('weekend');
                   $td.addClass('disabled');
               }
               if (thisDate.isHoliday()) // You need to code the method that supports this.
               {
                   $td.addClass('holiday');
                   $td.addClass('disabled');
               }
           }
       }
)

Where you do the check for thisDate.isWeekend, add in a check to see if the date has previously been selected as well. That way you give the user a good UI experience because you can show that a date has previously been selected. Now, you will also need to add a check in to the controller to prevent the user from adding a date that's previously been selected because you are working in a multi-user system here.

Ahh yes i see...the holiday method was a ice feature as well...I get what your saying Pete, but unfortunately I don't know how to hard code a check for the UI that will show what dates are already chosen, how can i pull the dates across?

Also regarding putting a check in the controller could you give any advice on this? I know what I am meant to do but don't know the syntax

datetime startDate

if statedate = db.holidayDate
MessageBox("error")

Hi Pete,
Im trying to give the UI experience of date if it has been previously accepted.

In My JS file:

HTML

/**
* An Array of day names starting with Sunday.
*/
Date.dayNames = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];

/**
* An Array of abbreviated day names starting with Sun.
*/
Date.abbrDayNames = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];

/**
* An Array of month names starting with Janurary.
*/
Date.monthNames = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];

/**
* An Array of abbreviated month names starting with Jan.
*/
Date.abbrMonthNames = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];

/**
* The first day of the week for this locale.
*/
Date.firstDayOfWeek = 1;

/**
* The format that string dates should be represented as (e.g. 'dd/mm/yyyy' for UK, 'mm/dd/yyyy' for US, 'yyyy-mm-dd' for Unicode etc).
*/
Date.format = 'dd/mm/yyyy';

/**
* The first two numbers in the century to be used when decoding a two digit year. Since a two digit year is ambiguous (and date.setYear
* only works with numbers < 99 and so doesn't allow you to set years after 2000) we need to use this to disambiguate the two digit year codes.
*/
Date.fullYearStart = '20';

(function () {
    function add(name, method) {
        if (!Date.prototype[name]) {
            Date.prototype[name] = method;
        }
    };

    /**
    * Checks if the year is a leap year.
    */
    add("isLeapYear", function () {
        var y = this.getFullYear();
        return (y % 4 == 0 && y % 100 != 0) || y % 400 == 0;
    });

    /**
    * Checks if the day is a weekend day (Sat or Sun).
    */
    add("isWeekend", function () {
        return this.getDay() == 0 || this.getDay() == 6;
    });

I'm tryihg to add a check into 'isWeekend' to include dates that already exist but don't know how.

Can you Advise?

Thanks

Hmm - I would do this differently. In order to get the dates that had already been selected, I would call back to the server to retrieve those dates and use that to blank out those dates in the UI.

Im using the kelvin luck J query datePicker....

Is this any help?

http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/datePickerDefaultToday.html[^]

It already selects todays date, maybe I could edit this somway to include dates that exist in the DB...just not sure of the syntax, ay help?
thanks

Maybe, for simplicities sake, you should just stick to informing the user that the date they picked is invalid. You seem very new to this, and adding complexity like this could well be beyond you right now - unfortunately, I don't have the time to write a fully working sample for you to demonstrate how this all hangs together.

Re: Run through loop for week and dont select weekends

10-Dec-12 4:13

SQL

So the user can select 2 different dates, a start date and an end date from 2 calendars, when they click 'add' the dates between&including the dates selected will be added to the DB, each date as a separate record.

This works fine however I dont want weekends to be added to the DB.

Iv updated the UI of datepicker http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/datePickerCustomCellRender.html but if a user selects fri-mon for example fri,sat,sun and mon will be added to the db Iv tried to only run the code if datyofweek is not saturday or sunday

public ActionResult listHolidays(Holiday holiday, int? PersonId, string HolidayDate, string endDate)
       {
           DateTime startDates = Convert.ToDateTime(HolidayDate),
                    endDates = Convert.ToDateTime(endDate);

           while (startDates <= endDates)
           {
               if (startDates.DayOfWeek != DayOfWeek.Saturday || startDates.DayOfWeek != DayOfWeek.Sunday)
               {
                   Holiday holiday1 = new Holiday();
                   holiday1.PersonId = PersonId.Value;
                   holiday1.HolidayDate = startDates;

                   db.Holidays.AddObject(holiday1);
                   db.SaveChanges();

               }

That's an AND condition, not an OR condition. It should read:

if (startDates.DayOfWeek != DayOfWeek.Saturday && startDates.DayOfWeek != DayOfWeek.Sunday)

Hi,

I have created a windows service, I want to deploy it on the server. Can anybody please help me in deploying it. When I googled for it, I found that I have to have project installer file in my project.

What is project installer file, how should I write it to deploy my windows service. I am new to this windows service field, any kind of help, code snippet, or link would be very helpful.

Thanks in advance.

Thanks & Regards,

As long as you aren't using Visual Studio 2012, this[^] should help.

Hi,

I am using Visual Studio 2010 but .Net Framework 3.5, I think it should work?

It should work. The steps really didn't change.
