Sitecore Feed latest 2 items

Sitecore Feed latest 2 items - c#

I have a sitecore web part that I am trying to get to display the top 2 most current items by date. I am having trouble because I am only able to get the latest item to show.
For the ascx Code:
<asp:Repeater ID="newsContainer" runat="server">
<ItemTemplate>
<div class="newsItem">
<h2>News</h2>
<a href="<%# SitecoreUtility.NavigateUrl((Item)Container.DataItem)%>" class="newsHeadline">
<span> <sc:Date ID="Date1" Item="<%# Container.DataItem %>" Field="Posted-Date" Format="MM.dd.yyyy" runat="server" />
<sc:Text ID="Text1" Item="<%# Container.DataItem %>" Field="Title" runat="server" />
</span>
</a>
<!-- <p class="newsSummary">
<asp:Literal ID="litBody" runat="server" Text="<%# SitecoreUtility.TruncateByWords(((Item)Container.DataItem).Fields[Constants.Fields.BODY].Value, 20) %>"></asp:Literal>
...
+ More</p> -->
</div>
</ItemTemplate>
</asp:Repeater>
<asp:Panel ID="pnlPagination" runat="server"></asp:Panel>
<asp:Panel ID="pnlArchive" runat="server">
<!-- <div class="newsArchiveLink">
View Archived News
</div> -->
</asp:Panel>
<asp:Panel ID="pnlCurrent" runat="server">
<div class="newsArchiveLink">
View Current News
</div>
</asp:Panel>
For the ASCX.CS File:
public partial class Homepage_NewsListing : BaseSublayout
{
int CurrentPage = 1;
int PageSize = Constants.Values.SEARCH_SMALL_LIST;
protected void Page_Load(object sender, EventArgs e)
{
CurrentPage = int.Parse(WebUtil.GetQueryString("page", "1"));
List<Item> newsListings = new List<Item>();
Item newsItems = SitecoreUtility.Db.GetItem(Constants.Items.NEWS);
if (WebUtil.GetQueryString("type", "") == "archive")
{
newsListings = newsItems.Children.Where(item =>
(SitecoreUtility.FormatDateAtMidnight(item, Constants.Fields.ARCHIVEDATE) <= DateTime.Now)
&&
(!string.IsNullOrEmpty(item.Fields[Constants.Fields.ARCHIVEDATE].Value))
).OrderBy(item => item.Fields[Constants.Fields.POSTED_DATE].Value).ToList();
pnlArchive.Visible = false;
//pnlCurrent.Visible = true;
pnlCurrent.Visible = false;
}
else
{
newsListings = newsItems.Children.Where(item =>
(SitecoreUtility.FormatDateAtMidnight(item, Constants.Fields.ARCHIVEDATE) > DateTime.Now)
||
(string.IsNullOrEmpty(item.Fields[Constants.Fields.ARCHIVEDATE].Value))
).OrderBy(item => item.Fields[Constants.Fields.POSTED_DATE].Value).ToList();
//pnlArchive.Visible = true;
pnlArchive.Visible = false;
pnlCurrent.Visible = false;
}
newsContainer.DataSource = DisplayResults(newsListings.OrderByDescending(item => item.Fields[Constants.Fields.POSTED_DATE].Value).ToList());
newsContainer.DataBind();
}
protected List<Item> DisplayResults(List<Item> results)
{
pnlPagination.Controls.Add(new Pager(results.Count, PageSize, CurrentPage).BuildPaging());
if (CurrentPage > 1)
return results.Skip((CurrentPage - 1) * PageSize).Take(PageSize).ToList();
return results.Take(PageSize).ToList();
}
}

I would first try to make your code a bit more simple (for debugging) and use a fast query to pull items within a date range.
var date = DateTime.Now.AddMonths(3);
var dateString = date.Year.ToString() + date.Month.ToString().PadLeft(2, '0') + date.Day.ToString().PadLeft(2, '0');
var newsList = Sitecore.Context.Database.SelectItems("fast:/sitecore/content/home/your-path-to-news/*[##templatename='Your template name' and #POSTED_DATE > '" + dateString + "']").ToList();
newsList = newsList.OrderByDescending(n => n.Fields["POSTED_DATE"].Value).Take(2).ToList();
newsContainer.DataSource = newsList;
newsContainer.DataBind();

How to split datetime and display on each dropdownlist column in C# aspnet

I have a TimeTable table and a Product table. Each product will have 4 timetable.
At my update product page, it should able to retrieve the latest timetable and split every timetable into respective dropdown list. Currently when i click update page, it only show the null calendar which is not I want. I want the calender to populate with the database time. My idea was to split the [day] [time] [am/pm] and then push to the dropdown list, But I do not know how can I achieve that. Anyone willing to guide me will be much appreciate thank you.

Your overall requirement is to split the time in the database into a single one and then get it from the database and display it on the page, right?
You can get it and then split it. I wrote a simple demo, which may help you:
Controller：
public IActionResult Index()
{
string time = "Every Monday 10 AM - 11 Am";
string[] ssize = time.Split(null);
ArrayList arlist = new ArrayList();
foreach (String s in ssize)
{
arlist.Add(s);
}
string data = (string)arlist[0];
ViewBag.data = data;
string data1 = (string)arlist[1];
ViewBag.data1 = data1;
string data2 = (string)arlist[2];
ViewBag.data2 = data2;
string data3 = (string)arlist[3];
ViewBag.data3 = data3;
string data4 = (string)arlist[4];
ViewBag.data4 = data4;
string data5 = (string)arlist[5];
ViewBag.data5 = data5;
string data6 = (string)arlist[6];
ViewBag.data6 = data6;
return View();
}
I have omitted the operation of getting the time from the database. After getting it, you can split it by space, traverse it and add it to alist, then get the data according to the subscript, and finally display it on the page.
View:
#ViewBag.data
<select><option>#ViewBag.data1</option></select>
<select><option>#ViewBag.data2</option></select>
<select><option>#ViewBag.data3</option></select>
#ViewBag.data4
<select><option>#ViewBag.data5</option></select>
<select><option>#ViewBag.data6</option></select>

Multiple upload in c# net 4.0

After saving information from a page in c# net 4.0 I need to add some pics in multiple mode.
I can't use net 4.5.
The problem :
If I open the page with multiple upload in the browser IE 11 this works correctly, and you can select multiple pics to upload.
If I open the same page as multiple upload in a window popup on IE 11, you can't select multiple pics to upload, but only a pic.
What's the problem ?
My code below, thank you in advance.

My asp:LinkButton, does not work for paging in my repeater when I first open my web page the asp:linkbutton is there, but when searched and display all the data from my page the linkbutton is gone although it display data that I searched for. But the problem is pagination doesn't seem to work. What seems to be the problem for my code? Here's the link as a reference for my code.
I'm new to c# programming(webform) and I have few knowledge about pagination in c#.

It's because of
int vcnt = cnt / pagedData.PageSize;
'cnt' you haven't set, So its always zero that's why 'vcnt' will zero.
that's why your link will visible false always after you search things.
So Solution is
int vcnt = dt.DefaultView.Count / pagedData.PageSize;
Hope this will solve your problem
Happy Coding :)

I got it right :)

HttpContext.Current.Session["MessageTable"] = dt;
foreach (string message in msgStack)

MasterPage ASP.net code:
<asp:UpdatePanel runat="server" ID="upMessage" ClientIDMode="Static" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="lblMessage" Font-Size="x-small" runat="server" Text="" ClientIDMode="Static"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
When I change the DropDown option the UpdatePanel in the masterpage doesn't update although putting a breakpoint there, shows that it is being hit.
How do I resolve the issue?

Basically, you want to expose Public Property from MasterPage. Then access it from ContentPage.
Master Page
<%# Master Language="C#" AutoEventWireup="true"
CodeBehind="Site.Master.cs" Inherits="DemoWebForm.Site" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<form id="form1" runat="server">
<asp:Label runat="server" ID="MessageLabel" />
<asp:ContentPlaceHolder ID="MainContent" runat="server">
</asp:ContentPlaceHolder>
</form>
</body>
</html>
public partial class Site : System.Web.UI.MasterPage
{
public string MessageLabelText
{
get { return MessageLabel.Text; }
set { MessageLabel.Text = value; }
}
}
Content Page
<%# Page Title="Home Page" Language="C#"
MasterPageFile="~/Site.Master"
AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="DemoWebForm._Default" %>
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
<asp:DropDownList ID="TaskNameDropDownList"
runat="server"
AutoPostBack="True"
OnSelectedIndexChanged="TaskNameDropDownList_SelectedIndexChanged">
<asp:ListItem Text="One" Value="1" />
<asp:ListItem Text="Two" Value="2" />
</asp:DropDownList>
</asp:Content>
public partial class _Default : Page
{
protected void TaskNameDropDownList_SelectedIndexChanged(
object sender, EventArgs e)
{
var master = Master as Site;
if (master != null)
{
master.MessageLabelText = TaskNameDropDownList.SelectedValue;
}
}
}
