Hello everyone,
I am working on 1 healthcare project. In that project there is a provision to book an appointment of patient. For appointment booking, I am using a check box to select time slot. Now I want to show/enable checkboxes according to hour/time. Example: if right now time is 12pm so user should not able to book appointment of 10 am, she only able to book appointment after 12pm.

Can anyone give some idea what should I do??
Thanks in advance....

On page load you can check the current time and disable the corresponding text-box.

How user is suppose to select timeslot? Have you provided predefined choices using checkbox?

So you have 24hrs(12am - 12pm) or total working 8 hours(9am - 5pm) checkboxes in your application?

Hi,

Add one field called Shift (AM/PM).

In database table add Shift along with Timing in master table.

While you display that timing just check

Where Now.ToString("tt")== DBValue.Shift

This is just hint you may use this logic to solve your issue.

I would define a Dictionary<CheckBox,int> that held the CheckBoxes corresponding to the time-slots for appointments as its Keys, and the offset from midnight to the beginning of the time-slot as its values:

C#

// code shown here is done in WinForms, but should map to ASP.NET easily

private Dictionary<CheckBox, int> dctCBxDTm;

// used to hold the current hour
private int currentHour;

private void YourApp_SomeInitializationEvent()
{
    // assume hourly appointments beginning at 8AM
    // an hour break for lunch, then 1PM ~ 4PM
    dctCBxDTm = new Dictionary<CheckBox, int>
    {
        {checkBox1, 8},
        {checkBox2, 9},
        {checkBox3, 10},
        {checkBox4, 11},
        {checkBox5, 13},
        {checkBox6, 14},
        {checkBox7, 15},
        {checkBox8, 16}
    };
}

Then I'd define a schedule update function:

C#

private void ScheduleUpdate()
{
    // get the current hour
    currentHour = DateTime.Now.Hour;

    // test if in working hours assume:
    // appointments can be scheduled
    // beginning 6am up to 3:59PM
    if (currentHour < 6 || currentHour > 16)
    {
        // use whatever to show a dialog
        MessageBox.Show("Thank you for using ACA HealthCare.\r\n\r\nTry again tomorrow if you are not dead.", "Morituri te Salutamus", MessageBoxButtons.OK, MessageBoxIcon.Warning);

        // exit
        return;
    }

    foreach (var kvp in dctCBxDTm)
    {
        kvp.Key.Enabled = kvp.Value >= currentHour;
    }
}

Obviously you need to determine how you want to call the update function, how frequently, etc. I'd do that "on demand" whenever a user of the system starts your site, after, I assume, a log-in process.

Hello betu.009,

Use the Observer pattern.

Hi Betu,

I tried your requirement that you can make use of it.
I have placed three checkbox in aspx page like this

ASP.NET

<asp:checkbox id="CheckBox1" runat="server" text="3 PM"/> <!--24Hr Text="15 PM"-->
<asp:checkbox id="CheckBox2" runat="server" text="4 PM"/> <!--24Hr Text="16 PM"-->
<asp:checkbox id="CheckBox3" runat="server" text="5 PM" /><!--24Hr Text="17 PM"-->

In server side, wrote a common validation function for checkbox

C#

protected void checkboxHoursValidate(CheckBox chkBox)
       {
           int hours = Convert.ToInt32(DateTime.Now.ToString("hh")); // 12Hr time format
           // int hours = DateTime.Now.Hour; // 24hr time format
           int chkbxHr = Convert.ToInt32(chkBox.Text.Split(' ')[0]);
           chkBox.Enabled = hours < chkbxHr;
       }

And in Page_Load method, am passing my required checkbox to the validation function like this

C#

checkboxHoursValidate(CheckBox1);
checkboxHoursValidate(CheckBox2);
checkboxHoursValidate(CheckBox3);

I checked at 4:45 PM IST, at that time it disables checkbox1(3 PM) and checkbox2(4 PM) respectively
Checkbox3(5 PM) alone is enabled.
Hope this gives you some idea how to make use of.

Regards,
RK
