Using Multiple Calendars in WebCalendar

Continuing my posts about Intersoft WebCalendar control for ASP.NET, I have described how to configure the holiday collection in WebCalendar, and how to get selected dates and perform multiple selection. If you missed the blog posts, please check it out here.

In this post, I will show you about how to configure WebCalendar to multiple calendars in multiple columns. Let’s start configuring the WebCalendar.

Unlike similar calendar controls, WebCalendar enables you to display multiple calendars. This behavior is controlled by the NumberOfCalendarDisplayed property.

When multiple calendars feature is enabled, only 1 calendar will be active when users switched to the year view or decade view.

The following screenshots show the multiple calendars feature in WebCalendar using different type of view mode.

As you can see from the above screenshots, WebCalendar’s default behavior is to display the multiple calendars in one column. To enable multiple columns option in WebCalendar, we can customize the CalendarItemWidth property to set the width of each calendar, and the Width property to control the WebCalendar’s width.

As an example, I will show you how to display a whole year calendar in 4×3 configurations.
Please follow the steps below.

  1. Set the NumberOfCalendarDisplayed property to 12.
  2. Set the CalendarItemWidth to 170px. The CalendarItemWidth is 1/4 from the entire WebCalendar’s width.
  3. Set the CalendarItemHeight to 180px. The CalendarItemHeight is 1/3 from the entire WebCalendar’s height.
  4. Set the Width property to 680px. We can get the Width property value from multiply the total column with CalendarItemWidth’s value.
  5. Set the Height property to 540px. We can get the Height property value from multiply the total row with CalendarItemHeight’s value.

Here is the result from the above WebCalendar configurations.

Get Multiple Selected Dates with WebCalendar

Calendar is a control that looks simple but very useful in desktop or web development, so there is no question why there are lots of calendar control out there. Those calendar controls usually can select single date or can return single date only.

In certain scenario, there is a requirement where you would like to be able to perform multiple selections or get multiple dates from the calendar control. For example in scheduling scenario, there is a condition that the event will be a range event or occur in custom date (the dates does not align), and many other scenarios that require more than just single selection or single date.

To overcome the above scenarios, WebCalendar control is implemented with “MultipleSelection” feature which can give you a range of date and multiple selections. In this post, I will show you how to enable this feature.

For your information, WebCalendar is part of WebEssentials suite for ASP.NET which contains 8 new controls such as WebAccordion, WebProgressBar, WebListBox, etc. For further information about WebEssentials can be found here.

Enable MultipleSelection in WebCalendar

The default selection behavior in WebCalendar is single selection. In single selection, you can access WebCalendar’s selected date value in SelectedDate property. In multiple selections, you can access WebCalendar’s slected dates value in SelectedDates collection property.

To enable MultipleSelection in WebCalendar, set EnableMultipleSelection property to True.

The following images show SelectedDate, SelectedDates and EnableMultipleSelection property in WebCalendar control.

When multiple selections feature is enabled, you can highlight multiple dates in WebCalendar using mouse. The behavior is the same with performing multiple selections in desktop OS (press, hold and drag the mouse).

Actually, you can also perform the multiple selections using keyboard. In order to use the keyboard action, EnableKeyboardSupport property in WebCalendar should be enabled. You will get the comprehensive multiple selection behavior in WebCalendar with the combination of mouse and keyboard. Like desktop OS, you can highlight WebCalendar’s date with click and drag using mouse, use CTRL, SHIFT, or CTRL + SHIFT to get random selections.

When keyboard support is enabled, you can also start using the directional keyboard keys to move between months and dates in WebCalendar. [Enter] key is used to select a date and [Space] key is used to cycle through the available views (Day, Month, Year) in WebCalendar.

Some illustration of multiple selections in WebCalendar is shown in the following screenshots and video.

For your information the multiple selections feature in WebCalendar is designed to work in Day view mode only.

Get Multiple Selected Dates from WebCalendar

In this post sample, I will show you how to get the previous/old selected dates and the latest/new selected dates from WebCalendar through OnSelectedDateChanged client side events and display the information for user. OnSelectedDateChanged client side event is the client side event in WebCalendar that will be triggered when WebCalendar’s SelectedDate or SelectedDates property value is changed.

First, enable WebCalendar’s EnableMultipleSelection and EnableKeyboardSupport property by set the property value to True then start implementing OnSelectedDateChanged client side event.

The following screenshots show the implementation of OnSelectedDateChanged client side event in WebCalendar.

image

function WebCalendar1_OnSelectedDateChanged(controlId, oldDates, newDates)
{
	var WebCalendar1 = ISGetObject(controlId); 

	return true;
}

Notice that OnSelectedDateChanged client side event has 3 parameters:

  • controlId is the id of the WebCalendar control
  • oldDates is the collection of the old selected dates
  • newDates is the collection of the new selected dates

Next, I will write simple code that will get the old and new selected date and put them as the div element’s innerHTML like illustrated in the following sample.

Here is the result after the above code implementation.

function WebCalendar1_OnSelectedDateChanged(controlId, oldDates, newDates)
{
    var WebCalendar1 = ISGetObject(controlId); 

    var oldDatesDiv = document.getElementById("oldDatesDiv");	    var newDatesDiv = document.getElementById("newDatesDiv");

    for (var i = 0; i < oldDates.length; i++)
	oldDatesDiv.innerHTML += oldDates[i] + "<br />";
	         for (var j = 0; j < newDates.length; j++)
	newDatesDiv.innerHTML += newDates[j] + "<br />";

    return true;
}

Here is the result after the above code implementation.

How to Configure Holiday in WebCalendar

Since Intersoft WebUI Studio 2010 R1, there is a new suite called WebEssentials for ASP.NET. WebEssentials contains 8 new controls in this release. WebCalendar control is one of the new controls which are part of WebEssentials. Further information about WebEssentials can be found here.

In business applications that use calendar user interface to create appointments or events, it is common to show the days which are holiday, and the days which are working days. This is important to avoid arranging meetings or events in undesired schedule. Our new WebCalendar control provides built-in features that let you easily define the holidays, which will be consequently marked in different color. In this post, I will show you how to setup the holiday in WebCalendar.

You can specify holiday in WebCalendar’s Holidays collection property as illustrated in the following screenshot.

Click on the Holidays property to open Holidays collection editor, as illustrated in the following screenshot.

Here are several points that should be notes in the Holidays Collection property.

  • Name
    The name of the holiday
  • Description
    The description of the holiday. This is the value of the WebCalendar’s date tooltip. Date The date of the holiday
  • IsGeneral
    The property that indicates whether date with the same specified date and month even though it is not in the same year will be set as a holiday. For example, you can specify IsGeneral to True when the specified holiday is Christmas Day.

Input the holiday value and click the Add button to add the new holiday to WebCalendar. Repeat the same steps to add another holiday.

Save and run the page after you have finished specifying the holiday to WebCalendar. You will have something like the following screenshot.

Notice that in WebCalendar, the holiday is marked with red color. This is because WebCalendar has a style which will be assigned to each of the holiday. The style property is called HolidayStyle. The default style for holiday in WebCalendar is marked the date with red color. However you can custom your own holiday style too by customizing the HolidayStyle property.

In this post you have learned how to create holiday in WebCalendar. For more information about WebCalendar and its feature, please click here.
