I have this table in a repeater that lists all contacts from database, if the user clicks on a specific contact, that contact should be highlighted with blue background color. I have tried this code, but it does not work...!
ASPX:
<asp:Repeater runat="server" OnItemCommand="rptList_OnItemCommand" ID="rptList">
<HeaderTemplate>
<table id="tblListContact">
<tr id="tblRowContact">
<th>
<asp:Label runat="server" Text="TRNSLTName" />
</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<%# ContactId.HasValue && ContactId == Convert.ToInt32(Eval("ID"))? "<tr style='background-color: #67C6FA;'>" : "<tr>" %> // Shouldn't this code make it work?
<td>
<asp:LinkButton runat="server" CommandName="selectContact" CommandArgument='<%# Eval("ID") %>'><%# Eval("Name") %></asp:LinkButton>

I am creating a quiz application in ASP.net (c#) and I currently have one question at a time displaying with the use of a datapager. However, when i move from question 1 to question 2 and then back to question 1 the radiobutton selection disappears.
EDIT - I now have the radio button retaining a selection whenever I move from next to previous, HOWEVER, If I chose radiobutton1 and then move on to question 2, It has radiobutton1 already selected, even though I am yet to answer that question. So for some reason whatever selection I make on question 1 is being duplicated to the other questions.
Question1 example

Try overriding LoadViewState and SaveViewState to maintain the state of your radio buttons. For example, try something like the following, and pull the values back out of ViewState wherever you need them:
protected override void LoadViewState(object savedState)
{
base.LoadViewState(savedState);
if (ViewState["Radio1"] != null)
Radio1.Text = (int)ViewState["Radio1"];
...
}
protected override object SaveViewState()
{
ViewState["Radio1"] = Radio1.Text;
...
return base.SaveViewState();
}
I have items in a database. The columns are ID, Region, and Report. I display all these in an asp listview. I need combine each of these items and display them in one row for each id. So for example if ID = testuser Regions = 1, 2 Reports = A, B
Right now the list displays something like this:
testuser | 1 | A
testuser | 1 | B
testuser | 2 | A
testuser | 2 | B
I want it to be:
testuser | 1,2 | A,B
Here is the front end:
<ItemTemplate>

{
List<string> selectedRegions = RegionsCheckBox.Items.Cast<ListItem>()

List<string> selectedReports = ReportsCheckBox.Items.Cast<ListItem>()

try
{
if (String.IsNullOrWhiteSpace(txtCWSID.Text))
{
this.lblError.Text = "Please enter a valid CWS ID";
return;
}
if (Common.GetUserCwsId() == txtCWSID.Text.Trim())
{
this.lblError.Text = "It would not be a good idea to block yourself from the site";
return;
}
ReportPermissionsFactory.DeleteReportPermissionUser(txtCWSID.Text, Common.GetConnectionString());
foreach (string Region in selectedRegions)
{
foreach (string Report in selectedReports)
{
ReportPermissionsFactory.InsUpdReportPermissions(txtCWSID.Text.Trim(),Region, Report, Common.GetConnectionString());
}
}
txtCWSID.Text = String.Empty;
BindList();
}
catch (Exception ex)
{
Logger.HandleException(Common.GetUserCwsId(), Projects.GlobalSizingTool, "ReportPermissionsUsers", "lbAddUser_Click", ex, Common.GetConnectionString());
this.lblError.Text = "There was an error completing your request. Please try again.";
}
}
Here is how the data gets loaded:
internal static List<ReportPermissions> LoadData(string connectionString, bool refresh = false)
{
string cacheItem = "ReportPermissionsFactory";
ObjectCache cache = MemoryCache.Default;
if (refresh)
{
cache.Remove(cacheItem);
}
List<ReportPermissions> l = cache[cacheItem] as List<ReportPermissions>;
if (l == null || l.Count == 0)
{
l = new List<ReportPermissions>();
Database db = DatabaseFactory.CreateDatabase(connectionString);
DbCommand wrapper = db.GetStoredProcCommand("usp_GetReportPermissionsUsers");
IDataReader reader = db.ExecuteReader(wrapper);
using (wrapper)
{
using (reader)
{
while (reader.Read())
{
ReportPermissions obj = new ReportPermissions();
obj.CwsId= SizingDBLayer.Utilities.GetDBFieldString(reader["CwsId"]);
obj.Regions = SizingDBLayer.Utilities.GetDBFieldString(reader["RegionCode"]);
obj.Reports = SizingDBLayer.Utilities.GetDBFieldString(reader["Reports"]);
l.Add(obj);
}
}
}
cache.Add(cacheItem, l, new DateTimeOffset(DateTime.Now.AddMinutes(5)));
}
return l;
}
I would create a new class (or even an anonymous object) that holds the Id along with a CSV of the Regions and Reports. Get the data in the same way you're doing, but group it by the CwsId and build up a new list of the new class. Something like:
public class ReportPermissionsById
{
public int CwsId { get; set; }
public string Regions { get; set; }
public string Reports { get; set; }
}
public void BindList()
{
var list = LoadData(connString);
var reportPermissionsById = list
.GroupBy(r => r.CwsId)
.Select(r =>
new ReportPermissionsById
{
CwsId = r.Key,
Regions = string.Join(",", r.Select(d => d.Regions)),
Reports = string.Join(",", r.Select(d => d.Reports)),
}
);
//Use reportPermissionsById to bind your ListView
}
Here's how this ended up working:
List<ReportPermissions> finalizedItems = new List<ReportPermissions>();
foreach (ReportPermissions rp in l)
{
//Check to see if record for this user exists
if (!finalizedItems.Any(x => x.CwsId == rp.CwsId))
{
// if it doesn't exist, get it
ReportPermissions perm = new ReportPermissions();
perm.CwsId = rp.CwsId;
perm.Reports = string.Join(",", l.Where(x => x.CwsId == rp.CwsId).Select(x => x.Reports).Distinct());
perm.Regions = string.Join(",", l.Where(x => x.CwsId == rp.CwsId).Select(x => x.Regions).Distinct());
finalizedItems.Add(perm);
}
}
l= finalizedItems;
I have a page SendResults.aspx that holds a button and a ListView with ItemTemplate set to a user control (3 labels and 2 textboxes) that gets it's data from a matching object.
On Page_Load I fill the List with data (this works well).
When the button is clicked I want to take the user input in the user-control's textboxes and do something with it.
However I always get the initial value and not the updated one.
Here is the code:
The user-control "MatchControl.ascx"
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="MatchControl.ascx.cs" Inherits="TotoMondeal.Controls.MatchControl" %>
<div>
<asp:Image ID="Team1FlagImage" runat="server" />
<asp:Label ID="Team1Label" runat="server" Width="150px"></asp:Label>
<asp:TextBox ID="Team1TextBox" runat="server" MaxLength="2" TextMode="Number" Width="50px" AutoPostBack="true" OnTextChanged="Team1TextBox_TextChanged"></asp:TextBox>
<asp:Label ID="Colon" runat="server" Font-Size="XX-Large" Text=":"></asp:Label>
<asp:TextBox ID="Team2TextBox" runat="server" MaxLength="2" TextMode="Number" Width="50px"></asp:TextBox>
<asp:Label ID="Team2Label" runat="server" Width="150px"></asp:Label>
<asp:Image ID="Team2FlagImage" runat="server" />
</div>
The user-control code-behind:
public partial class MatchControl : System.Web.UI.UserControl
{
public Match Match
{
get
{
object obj = ViewState["Match"];
return (obj == null) ? new Match() : (Match)obj;
}
set
{
ViewState["Match"] = value;
}
}
public string Team1Score
{
get { return Team1TextBox.Text; }
set { Team1TextBox.Text = value; }
}
public string Team2Score
{
get { return Team2TextBox.Text; }
set { Team2TextBox.Text = value; }
}
protected void Page_Load(object sender, EventArgs e)
{
Team1Label.Text = Match.Team1Name;
Team2Label.Text = Match.Team2Name;
Team1TextBox.Text = Match.Team1Score.ToString();
Team2TextBox.Text = Match.Team2Score.ToString();
Team1TextBox.Enabled = Match.EnableTextBox;
Team2TextBox.Enabled = Match.EnableTextBox;
Team1FlagImage.ImageUrl = #"~/FlagImages/" +Match.Team1Name + ".png";
Team2FlagImage.ImageUrl = #"~/FlagImages/" + Match.Team2Name + ".png";
}
protected void Team1TextBox_TextChanged(object sender, EventArgs e)
{
TextBox textBox = sender as TextBox;
if (textBox != null)
{
try
{
Match updatedMatch = new Match()
{
MatchId = Match.MatchId,
MatchDate = Match.MatchDate,
Result = Match.Result,
Team1Name = Match.Team1Name,
Team1Score = Convert.ToInt32(textBox.Text),
Team2Name = Match.Team2Name,
Team2Score = Match.Team2Score,
EnableTextBox = Match.EnableTextBox
};
Match = updatedMatch;
}
catch (Exception ex)
{
throw ex;
}
}
}
The SendResults.aspx:
<%# Page Title="שלח תוצאות" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="SendResults.aspx.cs" Inherits="TotoMondeal.SendResults" %>

</asp:ListView>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
</div>
</asp:Content>
the SendResults code-behind:
public partial class SendResults : Page
{
protected void Page_Load(object sender, EventArgs e)
{
List<Match> matches = new List<Match>();
matches = Queries.GetTodayMatches(DateTime.Now);
foreach (Match match in matches)
{
match.EnableTextBox = true;
}
this.TodayMatchesList.DataSource = matches;
this.TodayMatchesList.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < TodayMatchesList.Items.Count; i++)
{
MatchControl match = (MatchControl)TodayMatchesList.Items[i].FindControl("MatchControl");
TextBox textBox = (TextBox)match.FindControl("Team1TextBox");
string txt = textBox.Text;
}
}
}
The problem is that in this line:
TextBox textBox = (TextBox)match.FindControl("Team1TextBox");
string txt = textBox.Text;
I always get the initial value from the database, and not the user updated input.
Please help I'm new at this.
Your List is getting overwritten every time you post back. Add this in Page_Load for SendResults
if ( !Page.IsPostBack )
{
List<Match> matches = new List<Match>();
matches = Queries.GetTodayMatches(DateTime.Now);
...etc...
}
In addition to checking IsPostBack you need to handle saving your control properties in the ViewState. As suggested here: User control (ascx) and properties
Example from post:
public string Title {
get { return Convert.ToString(ViewState["Title"]); }
set { ViewState["Title"] = value; }
}
You would do this in your control class.
This is sort of a weird question, but is there a way to insert <p> tags around some imported text? I have a list of blog entries, each of which comes from its own source (I think it's a copy-paste job into Sitecore). All entries have an "Introduction" which is the blurb about the article. Some of these has <p> tags enclosing them and others do not (I'm not sure why and I can't change the source material--I can only have control on how it looks when it comes into the blog listing page) I'm thinking there should be a check to see if they do exist first, although I am not sure how that could be done.
This is the front end for the blog listing:

You can always do something like...
dr["Introduction"] = BlogEntry.Fields["Introduction"].Value
.Replace("\n\n", "</p><p>");
... or whichever escape characters are being used to denote separation of paragraphs in your source data. Alternatively, you could use Regex utilities. See Example 3 in this article for further reference.
Firstly in your GridView you've got
OnItemDataBound="EntryDataBound"
OnItemDataBound isn't an event of GridView I'm a little surprised that works!
Use
OnRowDataBound="EntryList_RowDataBound"
This is my common pattern for GridView's and Repeaters, noticed I've used a Literal control in the HTML, I'm not a mega fan of Eval! Also note that if (dataItem == null) just if there's a data item for that row, RowTypes like header and footer don't have any data, it's easier than the typical if(e.Row.RowType == DataControlRowType.Header) etc
<asp:GridView ID="EntryList" runat="server" OnRowDataBound="EntryList_RowDataBound" AllowPaging="true" PageSize="3" AutoGenerateColumns="false" EnablePersistedSelection="true" DataKeyNames="EntryID" OnPageIndexChanging="grdTrades_PageIndexChanging" GridLines="None" PagerSettings-Position="TopAndBottom" CssClass="mGrid" PagerStyle-CssClass="pagination" RowStyle-CssClass="norm" AlternatingRowStyle-CssClass="altColor" Width="100%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<li class="wb-entry-list-entry">
<div class="imgOuter">
<div class="imgInner">
<asp:Image runat="server" ID="EntryImage" CssClass="wb-image" ImageUrl='<%# Eval("Image") %>' />
</div>
</div>
<div class="outer">
<div class="wb-entry-detail">
<h2>
<%# Eval("Title") %>
</h2>
<div class="wb-details">
<%# Eval("EntryDate") %>
<%# Eval("Author") %><br />
<%# Eval("AuthorTitle") %>
</div>
<asp:Literal runat="server" ID="IntroductionLiteral"/>
<asp:HyperLink ID="BlogPostLink" runat="server" CssClass="wb-read-more" NavigateUrl='<%# Eval("EntryPath") %>'><%# Sitecore.Globalization.Translate.Text("READ_MORE")%></asp:HyperLink>
<asp:PlaceHolder ID="CommentArea" runat="server">
<span class="wb-comment-count"></span>
</asp:PlaceHolder>
</div>
</div>
</li>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<EmptyDataTemplate>
<%#Sitecore.Globalization.Translate.Text("NO_POSTS_FOUND")%>
</EmptyDataTemplate>
</asp:GridView>
.cs file
protected void EntryList_RowDataBound(object sender, GridViewRowEventArgs e)
{
var dataItem = e.Row.DataItem as EntryItem;
if (dataItem == null)
return;
var imageControl = e.Row.FindControl("EntryImage") as global::Sitecore.Web.UI.WebControls.Image;
var introductionControl = e.Row.FindControl("IntroductionLiteral") as Literal;
if (imageControl == null || introduction == null)
return;
imageControl.MaxWidth = m_imageMaxSize.Width;
imageControl.MaxHeight = m_imageMaxSize.Height;
if (dataItem.ThumbnailImage.MediaItem == null)
imageControl.Field = "Image";
if (!string.IsNullOrEmpty(data["introduction"]))
introductionControl.Text = string.Format("<p>{0}</p>", data["introduction"].ToString().Replace("\n\r", "</p><p>"));
}
Also if you've got a list of Sitecore objects why don't you just bind that to the GridView, then in your RowDataBound method get the item back
var dataItem = e.Row.DataItem as Item;
and then do the logic in the BindEntries method in there, would prob be cleaner code and you wouldn't have to use stupid DataSets! Just an idea.
I want to bind the CourseFee[] array to repeater.
I want to bind Amount and CourseFeeType.Descr in my repeater.
How do I bind it?
Sample Class
public class Order
{
public CourceFeeType FeeType;
public int Amount;
public int CourseFee;
public void AddFeeTypeDetails(CourceFeeType Fees)
{
FeeType = new CourceFeeType();
FeeType.Code = Fees.Code;
FeeType.Desc = Fees.Desc;
}
// Nested class
public class CourceFeeType
{
public String Code;
public String Desc;
}
}
Sample Form Load Code
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
List<Order> List = new List<Order>();
Order OrderObj = new Order();
Order.CourceFeeType Fees = new Order.CourceFeeType();
Fees.Code = "1";
Fees.Desc = "w2s";
OrderObj.Amount = 1;
OrderObj.AddFeeTypeDetails(Fees);
List.Add(OrderObj);
OrderObj = new Order();
OrderObj.Amount = 2;
Fees = new Order.CourceFeeType();
Fees.Code = "2";
Fees.Desc = "w22s";
OrderObj.AddFeeTypeDetails(Fees);
List.Add(OrderObj);
rpt.DataSource = List;
rpt.DataBind();
}
}
Repeater Item Bound Data Event Code
protected void rpt_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Label lbl = (Label)e.Item.FindControl("lblDescription");
lbl.Text = ((Order)e.Item.DataItem).FeeType.Desc;
Label lblAmount = (Label)e.Item.FindControl("lblAmount");
lblAmount.Text = ((Order)e.Item.DataItem).Amount.ToString();
}
}
Sample HTML
<asp:Repeater ID="rpt" runat="server" OnItemDataBound="rpt_ItemDataBound">
<HeaderTemplate>
<table>
<tr>
<td>
Amount
</td>
<td>
Description
</td>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:Label ID="lblAmount" runat="server"></asp:Label>
</td>
<td>
<asp:Label ID="lblDescription" runat="server"></asp:Label>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
