Filtering news item by date range in asp.net
To filter news items by date range in ASP.NET, you can use the following steps:
Step 1: Create a date range filter
Create a DateRange
class to hold the start and end dates for the filter:
public class DateRange
{
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
}
Step 2: Create a news item model
Create a NewsItem
model to hold the news item data:
public class NewsItem
{
public int Id { get; set; }
public string Title { get; set; }
public DateTime PublishDate { get; set; }
// other properties...
}
Step 3: Create a news item repository
Create a NewsItemRepository
class to retrieve news items from a data source (e.g., database):
public class NewsItemRepository
{
public List<NewsItem> GetNewsItemsByDateRange(DateRange dateRange)
{
// retrieve news items from database or other data source
// using the date range filter
return newsItems.Where(n => n.PublishDate >= dateRange.StartDate && n.PublishDate <= dateRange.EndDate).ToList();
}
}
Step 4: Create a news item controller
Create a NewsItemController
class to handle requests for news items:
public class NewsItemController : Controller
{
private readonly NewsItemRepository _repository;
public NewsItemController(NewsItemRepository repository)
{
_repository = repository;
}
public ActionResult Index(DateRange dateRange)
{
var newsItems = _repository.GetNewsItemsByDateRange(dateRange);
return View(newsItems);
}
}
Step 5: Create a view to display news items
Create a Index.cshtml
view to display the filtered news items:
@model List<NewsItem>
<h2>News Items</h2>
<table>
<thead>
<tr>
<th>Title</th>
<th>Publish Date</th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr>
<td>@item.Title</td>
<td>@item.PublishDate.ToString("yyyy-MM-dd")</td>
</tr>
}
</tbody>
</table>
Step 6: Add a date range filter to the view
Add a date range filter to the view using HTML controls:
@using (Html.BeginForm("Index", "NewsItem", FormMethod.Get))
{
<div>
<label for="startDate">Start Date:</label>
<input type="date" id="startDate" name="dateRange.StartDate" />
<label for="endDate">End Date:</label>
<input type="date" id="endDate" name="dateRange.EndDate" />
<input type="submit" value="Filter" />
</div>
}
Step 7: Update the controller to handle the filter
Update the NewsItemController
to handle the date range filter:
public ActionResult Index(DateRange dateRange)
{
var newsItems = _repository.GetNewsItemsByDateRange(dateRange);
return View(newsItems);
}
That's it! Now you can filter news items by date range using the DateRange
filter.
