Step 1. Create the calendar view
Create a View for the Calendar
Create a new Razor view named Calendar.cshtml in the Views/Home directory and include the FullCalendar setup.
Initialize the JS and CSS file as the below attachment.
<div class="col-lg-5 ">
<div class="w-100 m-t-6 task-calendar">
<div class="card mb-0">
<div class="card-header">
<div>
<h5>Task Calendar</h5>
<span class="d-inline-block calender-date"></span>
</div>
<div>
<!-- Status badges will be dynamically appended here -->
</div>
</div>
<div class="card-body p-3">
<div class="table-scrol">
<table class="table table-bordered mb-0 tblTaskDetails">
<thead>
<tr>
<th>Sl#</th>
<th>Activity</th>
<th>Region</th>
<th>Mines</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
</div>
</div>
</div>
</div>
</div>
Step 2. Write the Javascript code
<script type="text/javascript">
document.addEventListener('DOMContentLoaded', function () {
var calendarEl = document.getElementById('calendar');
var calendar = new FullCalendar.Calendar(calendarEl, {
initialView: 'dayGridMonth',
headerToolbar: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay'
},
events: function (fetchInfo, successCallback, failureCallback) {
$.ajax({
url:"@Url.Action("FetchCalenderData", "User")",
method: 'GET',
dataType: 'json',
success: function (response) {
if (response.status === "Successful") {
// Aggregate events by date and status
var aggregatedEvents = {};
response.data.forEach(function (item) {
var date = item.actionDate;
var status = item.actionStatus;
if (!aggregatedEvents[date]) {
aggregatedEvents[date] = {};
}
if (!aggregatedEvents[date][status]) {
aggregatedEvents[date][status] = 0;
}
aggregatedEvents[date][status]++;
});
// Transform aggregated data into FullCalendar event format
var events = [];
for (var date in aggregatedEvents) {
for (var status in aggregatedEvents[date]) {
events.push({
title: status + ' (' + aggregatedEvents[date][status] + ')',
start: date,
extendedProps: {
status: status,
statusCount: aggregatedEvents[date][status]
}
});
}
}
successCallback(events);
} else {
console.log('Error: Data status is not successful');
failureCallback();
}
},
error: function (jqXHR, textStatus, errorThrown) {
console.log('Error: ' + textStatus);
failureCallback();
}
});
},
eventClick: function (info) {
var status = info.event.extendedProps.status;
var clickedDate = info.event.start;
/*Date Formating For Send To DB for Filter*/
const CurrentDateForDB = new Date(clickedDate);
const year = CurrentDateForDB.getFullYear();
const month = String(CurrentDateForDB.getMonth() + 1).padStart(2, '0');
const day = String(CurrentDateForDB.getDate()).padStart(2, '0');
const ClickedformattedDate = `${year}-${month}-${day}`;
/*END*/
var options = { day: 'numeric', month: 'short', year: 'numeric' };
var formattedDate = clickedDate.toLocaleDateString('en-US', options);
// Make an AJAX call with the status name
$.ajax({
url: "@Url.Action("FetchActivityDtlsByStatus", "User")",
method: 'GET',
data: { ActivityStatus: status, ActivityDate: ClickedformattedDate },
success: function (response) {
console.log(response);
if (response.status === "Successful") {
var tbody = $('.tblTaskDetails tbody');
tbody.empty(); // Clear existing rows
response.data.forEach(function (item, index) {
var row = '<tr>' +
'<td>' + (index + 1) + '</td>' +
'<td>' + item.activiTyName + '</td>' +
'<td>' + item.regionName + '</td>' +
'<td>' + item.minesName + '</td>' +
'</tr>';
tbody.append(row);
});
if (clickedDate) {
$('.calender-date').text(formattedDate);
} else {
$('.calender-date').text('No Date Clicked');
}
// Clear existing status badges
$('.card-header div:nth-child(2)').empty();
// Display all unique statuses
var statusColors = {
'Approved': 'text-bg-success',
'Open': 'text-bg-primary',
'InProgress': 'text-bg-warning'
};
var uniqueStatuses = [...new Set(response.data.map(item => item.activityStatus))];
uniqueStatuses.forEach(function (status) {
var badgeClass = statusColors[status] || 'text-bg-secondary'; // Default color if status is not mapped
var statusBadge = '<h5>Status</h5><span class="badge ' + badgeClass + ' calender-status">' + status + '</span>';
$('.card-header div:nth-child(2)').append(statusBadge);
});
} else {
alert('Error: Data status is not successful');
}
},
error: function (jqXHR, textStatus, errorThrown) {
console.log('Error: ' + textStatus);
}
});
}
});
calendar.render();
});
</script>
Step 3. Write the Controller code
#region------------------------Calendar View-------------------------------------
/// <summary>
/// CalenderView Page
/// </summary>
/// <returns></returns>
[HttpGet]
public IActionResult CalenderView()
{
return View();
}
/// <summary>
/// Fetch Data For Calendar Added By Prakash on 24-May-2024
/// </summary>
/// <returns></returns>
[HttpGet]
public async Task<IActionResult> FetchCalenderData()
{
FetchCalendarData fcdaTa = new FetchCalendarData();
try
{
using (var httpClient = new HttpClient(_clientHandler))
{
var response = await httpClient.PostAsJsonAsync(_options._apiRootURL + "User/GetCalendarData", fcdaTa);
if (response.StatusCode.ToString() != "ServiceUnavailable")
{
string apiResponse = await response.Content.ReadAsStringAsync();
var ResultData = JsonConvert.DeserializeObject<FetchCalendarDataInfo>(apiResponse);
return Json(ResultData);
}
}
}
catch (Exception ex)
{
throw ex;
}
return Json("");
}
/// <summary>
/// Fetch Data for Activity Table By Activity Status Added By Prakash on 24-May-2024
/// </summary>
/// <returns></returns>
[HttpGet]
public async Task<IActionResult> FetchActivityDtlsByStatus(FetchActivityDetailsData fcdaTa)
{
try
{
using (var httpClient = new HttpClient(_clientHandler))
{
var response = await httpClient.PostAsJsonAsync(_options._apiRootURL + "User/GetActivityDtlsByStatus", fcdaTa);
if (response.StatusCode.ToString() != "ServiceUnavailable")
{
string apiResponse = await response.Content.ReadAsStringAsync();
var ResultData = JsonConvert.DeserializeObject<FetchActivityDetailsDataInfo>(apiResponse);
return Json(ResultData);
}
}
}
catch (Exception ex)
{
throw ex;
}
return Json("");
}
#endregion-----------------------------------------------------------------------
Step 4. Page load JSON response

"data": [
{
"actionDate": "2024-05-23",
"actionStatus": "Open"
},
{
"actionDate": "2024-05-23",
