• Updating an image's ImageUrl within a Repeater

  - by Django Reinhardt

  I hope someone can help me. It's a pretty newbie question, I'm afraid. I have an image inside a repeater, and I would like to change its IMAGEURL based on parameter that's being passed to it. <asp:Repeater ID="Repeater" runat="server"> <HeaderTemplate> <asp:Image ID="imgType" runat="server" /> </HeaderTemplate> <ItemTemplate> <%# Eval("DisplayName")%> </ItemTemplate> <SeparatorTemplate> <hr /> </SeparatorTemplate> </asp:Repeater> There is a SWITCH statement in the code behind that is altering the IMAGEURL depending on what's being passed to it. Inevitably, however, the images ID ("imgType") is not visible to the SWITCH statement (presumably because it's inside a REPEATER). Any suggestions on the best way to implement this would be greatly appreciated. Sorry for such a newbie question.

• page variable in a repeater

  - by carrot_programmer_3

  Hi I'm having a bit of an issue with a asp.net repeater I'm building a categories carousel with the dynamic categories being output by a repeater. Each item is a LinkButton control that passes an argument of the category id to the onItemClick handler. a page variable is set by this handler to track what the selected category id is.... public String SelectedID { get { object o = this.ViewState["_SelectedID"]; if (o == null) return "-1"; else return (String)o; } set { this.ViewState["_SelectedID"] = value; } } problem is that i cant seem to read this value while iterating through the repeater as follows... <asp:Repeater ID="categoriesCarouselRepeater" runat="server" onitemcommand="categoriesCarouselRepeater_ItemCommand"> <ItemTemplate> <%#Convert.ToInt32(Eval("CategoryID")) == Convert.ToInt32(SelectedID) ? "<div class=\"selectedcategory\">":"<div>"%> <asp:LinkButton ID="LinkButton1" CommandName="select_category" CommandArgument='<%#Eval("CategoryID")%>' runat="server"><img src="<%#Eval("imageSource")%>" alt="category" /><br /> </div> </ItemTemplate> </asp:Repeater> calling <%=SelectedID%> in the item template works but when i try the following expression the value of SelectedID returns empty.. <%#Convert.ToInt32(Eval("CategoryID")) == Convert.ToInt32(SelectedID) ? "match" : "not a match"%> the value is being set as follows... protected void categoriesCarouselRepeater_ItemCommand(object source, RepeaterCommandEventArgs e) { SelectedID = e.CommandArgument); } Any ideas whats wrong here?

• undefined method `build_users' with nested models

  - by Cédric

  I've got into trouble with nested attributes. Here is my Account model : class Account < ActiveRecord::Base has_many :products has_many :blogs has_many :openings has_many :users has_one :logo, :class_name => "AccountPicture" has_one :address, :class_name => "AccountAddress" has_and_belongs_to_many :options accepts_nested_attributes_for :logo, :allow_destroy => true accepts_nested_attributes_for :address, :allow_destroy => true accepts_nested_attributes_for :users, :allow_destroy => true end And here is my User model : class User < ActiveRecord::Base belongs_to :account end As you can see, Account accepts nested attributes for logo, address, and users. While testing, i can use nested attributes for logo and address, but not for user. a = Account.new => #<Account id: nil, hostname: nil, subdomain: nil, name: nil, description: nil, base_line: nil, footer: nil, phone_number: nil, mobile_number: nil, email_address: nil, created_at: nil, updated_at: nil> # building the address works fine >> a.build_address => #<AccountAddress id: nil, account_id: nil, country: nil, state: nil, county: nil, city: nil, suburb: nil, zipcode: nil, street: nil, streetno: nil, longitude: nil, latitude: nil, error_code: nil> # building the users fails >> a.build_users NoMethodError: undefined method `build_users' for #<Account:0x7f6862a5f948> from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):2 Thus, in my views, when i use the nested forms, i got this error back : User(#69850615730460) expected, got Array(#69850664775200) Any help would be appreciated.

• Alternative to Nested Loop For Comparison

  - by KGVT

  I'm currently writing a program that needs to compare each file in an ArrayList of variable size. Right now, the way I'm doing this is through a nested code loop: if(tempList.size()>1){ for(int i=0;i<=tempList.size()-1;i++) //Nested loops. I should feel dirty? for(int j=i+1;j<=tempList.size()-1;j++){ //*Gets sorted. System.out.println(checkBytes(tempList.get(i), tempList.get(j))); } } I've read a few differing opinions on the necessity of nested loops, and I was wondering if anyone had a more efficient alternative. At a glance, each comparison is going to need to be done, either way, so the performance should be fairly steady, but I'm moderately convinced there's a cleaner way to do this. Any pointers?

• Using Synology NAS attached to WDS-Repeater

  - by Kai B

  I'm using the following devices for my home network: Router 1: Speedport W 723 V (192.168.2.1) Router 2: AVM Fritzbox 3270 (192.168.2.2) NAS: Synology DS 207+(192.168.2.3) I successfully set up a WDS connection between the two routers. The Speedport acts as basestation, the Fritzbox repeats the WIFI signal of the Speedport. Everything fine, so far. Now I'm trying to achieve the following: Client → Speedport (Base) → Fritzbox (Repeater) → Synology NAS I want to use my Synology NAS attached to the Fritzbox (which is in repeating mode). I already gave it a static IP (as written above) but all connection attempts failed. Did I miss something out or is this set-up simply impossible?

• ASP.NET Repeater Control Not Working in FireFox

  - by Robert Hyland

  everyone: I have an ASP.NET Application that uses a Repeater control to display a thumbnail gallery. When the user mouses over one of the thumbnails, the main image will present that thumbnail. It uses a Repeater control in a UserControl like this: <asp:Image ID="pictureImage" runat="server" Visible="true" Width="200px" /> <asp:Repeater ID="rpProductImages" runat="server" Visible="false"> <ItemTemplate> <div> <div style="float: left" id="smallImage" runat="server"> <div class="smallAltImage" onmouseover="showImage();" style="border: 1px solid #999999; margin: 5px 5px 5px 4px; width: 45px; height: 45px; background-position: center; background-repeat: no-repeat; background-image: url('<%#ResolveClientUrl(productImagesPath)%><%# String.Format("{0}", DataBinder.Eval(Container.DataItem, "ImageName")) %>');"> </div> <asp:Label ID="lblImageName" runat="server" Visible="false"><%# Eval("ImageName")%></asp:Label> </div> </div> </ItemTemplate> </asp:Repeater> Then, in a javascript file, this: function showImage(){ // Get thumbnail path. var img = (this.style.backgroundImage).substring(4, (this.style.backgroundImage).length - 1); $('#ctl00_ContentPlaceHolder1_ProductDetails1_pictureImage').attr('src', img); } It works fine in IE9, displaying the fully-qualified path for the image. In FireFox8, however, the img src looks like this: ""ProductImages/K42JY_500.jpg"" ... with two-sets of quotes! I think that the Repeater control is the central cause of the problem but I Googled and Googled again and could not find anyone that has experienced this similar situation! In fact, I'll PayPal anyone who can help me solve this with $50.00 (can't you tell I'm in the XMAS spirit, here?!) Any help is appreciated and "Thank You" in advance!

• adding multiple <asp:Hyperlink>s into a repeater

  - by Colin Pickard

  I have a repeater control, and I want to put an unknown number of <asp:Hyperlink>s into the template, for example if you start with this: <asp:Repeater runat="server" ID="PetsRepeater"> <ItemTemplate> <%#DataBinder.Eval(Container.DataItem, "Owner")%> <%#this.ListPets(Container.DataItem)%> </ItemTemplate> </asp:Repeater> and in code behind: public partial class test1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { PetOwner p = new PetOwner() { Owner = "Jimmy", PetNames = new List<String>() { "Nemo", "Dory" } }; List<PetOwner> PetOwners = new List<PetOwner>() { p }; PetsRepeater.DataSource = PetOwners; PetsRepeater.DataBind(); } } protected String ListPets(Object PetOwner) { StringBuilder sb = new StringBuilder(); foreach (String Name in ((PetOwner)PetOwner).PetNames) { if (sb.Length > 0) sb.Append(", "); sb.Append(Name); } return sb.ToString(); } } class PetOwner { public String Owner; public List<String> PetNames; } Now suppose instead of having the string "Nemo, Dory" in my repeater, I want something like this: <asp:HyperLink runat=server Text="Nemo" NavigateUrl="Pet.aspx?Name=Nemo" />, <asp:HyperLink runat=server Text="Dory" NavigateUrl="Pet.aspx?Name=Dory" /> How can I do that? I tried putting a foreach inline in the aspx page, but I get the error Invalid expression term 'foreach'.

• how to save nested form attributes to database

  - by siulamvictor

  I am not really understand how's the nested attributes work in Rails. I have 2 models, Accounts and Users. Accounts has_many Users. When a new user filled in the form, Rails reported User(#2164802740) expected, got Array(#2148376200) Is that Rails cannot read the nested attributes from the form? How can I fix it? How can I save the data from nested attributes form to database? Thanks all~ Here are the MVCs: Account Model class Account < ActiveRecord::Base has_many :users accepts_nested_attributes_for :users validates_presence_of :company_name, :message => "companyname is required." validates_presence_of :company_website, :message => "website is required." end User Model class User < ActiveRecord::Base belongs_to :account validates_presence_of :user_name, :message => "username too short." validates_presence_of :password, :message => "password too short." end Account Controller class AccountController < ApplicationController def new end def created end def create @account = Account.new(params[:account]) if @account.save redirect_to :action => "created" else flash[:notice] = "error!!!" render :action => "new" end end end Account/new View <h1>Account#new</h1> <% form_for :account, :url => { :action => "create" } do |f| %> <% f.fields_for :users do |ff| %> <p> <%= ff.label :user_name %><br /> <%= ff.text_field :user_name %> </p> <p> <%= ff.label :password %><br /> <%= ff.password_field :password %> </p> <% end %> <p> <%= f.label :company_name %><br /> <%= f.text_field :company_name %> </p> <p> <%= f.label :company_website %><br /> <%= f.text_field :company_website %> </p> <% end %> Account Migration class CreateAccounts < ActiveRecord::Migration def self.up create_table :accounts do |t| t.string :company_name t.string :company_website t.timestamps end end def self.down drop_table :accounts end end User Migration class CreateUsers < ActiveRecord::Migration def self.up create_table :users do |t| t.string :user_name t.string :password t.integer :account_id t.timestamps end end def self.down drop_table :users end end Thanks everyone. :)

• Error using ASP.NET 3.5 Chart control within a Repeater control

  - by tuseau

  Hi, I'm getting the error "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd" at runtime from my Chart control. I have read one solution to this error message as documented here: http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/1dc4b352-c9a5-49dc-8f35-9b176509faa1/ but this does not solve my problem. I have the Chart within a Repeater control, which is within an ajax UpdatePanel. When I take the chart out of the Repeater (but leave it in the UpdatePanel), it works. So I'm thinking it is to do with the Repeater. Anyone got any ideas? Thanks in advance.

• ASP.NET Repeater Causing JQuery Image Slider

  - by Bry4n

  I have a jquery Image slider in a content page that worked fine. Once I converted it into a asp repeater the first image of the repeater would display twice, then run normally. Any idea on why the repeater is causing this? I think I discovered that the first image link <ItemTemplate> <a href='<%#Eval("Url")%>'> <img src='<%#Eval("Image")%>' alt="Spring Break 2011" rel='<h3><%#Eval("Title")%></h3><%#Eval("Caption")%>'/></a> </ItemTemplate> I have to place class="show" in the first item only. Does anyone know how to implement this during the first time it goes through. Hmm

• Nested class or not nested class?

  - by eriks

  I have class A and list of A objects. A has a function f that should be executed every X seconds (for the first instance every 1 second, for the seconds instance every 5 seconds, etc.). I have a scheduler class that is responsible to execute the functions at the correct time. What i thought to do is to create a new class, ATime, that will hold ptr to A instance and the time A::f should be executed. The scheduler will hold a min priority queue of Atime. Do you think it is the correct implementation? Should ATime be a nested class of the scheduler?

• Allow repeater to be arranged using drag-drop

  - by o-logn

  Hey all, I have a repeater that's bound to a SQL Data Source (using ASP.NET). Are there any JQuery plugins/efficient way of converting my repeater into something that can be sorted via drag and drop? i.e. users can rearrange the order of the data, which updates the database? Thanks

• Get the row changed in repeater

  - by o-logn

  Hey, I've got a repeater which is placed inside an updatepanel. When the user enters a new value, the repeater is updated without a postback. Is it possible to get the row that was updated in JQuery so that I can place an effect on it to make the change less subtle? For example, I'd like to fade a new color in on just the row that was changed. Thanks

• DDWRT or similar as repeater in a network.

  - by Quantumplation

  I have a friend with sever connection issues due to her wireless router being on the bottom floor of her house, and the computer being a story or two away. I have several old Linksys routers lying about, one of which is currently running DDWRT for my network. Would it be a good idea (effective) to configure one of these routers as a wireless bridge of some kind in an intermediary floor to improve her connection? Is there any specific configuration beyond the standard DDWRT setup that I would need to do? Thanks for your help. =)

• C# Wholesale Order form - textboxes in Gridviews in Repeater

  - by tnriverfish

  I'm building a wholesale order form on a website. The current plan is to... -get an ArrayList of DepartmentUnits -a DepartmentUnit has various attributes like "deptId", "description" and its own ArrayList of StoreItems -The StoreItems have attached ArrayList of various SizeOptions -The SizeOptions have an inventory count integer along with their description -Planning on putting an asp:Repeater on the page that has an asp:GridView in it -Each DepartmentUnit will have its own GridView -EachStore item will have a row in the GridView -Each SizeOption will have a TextBox in the row (approximately 10 options) -Each inventory count will be watermarked over the size option textbox The question becomes how will I then collect all this information correctly once the form has been filled out? I don't like the idea of putting all this information in an update panel and then posting back each time a GridView row or worse one of the row's textboxes changes. Any advice on putting a single save button on the page and looping through each Repeater item - and each GridViewRow - and each textbox - to get all the values entered? Better to try collecting all the items added in a single table at the bottom of the page and updating the string with jquery each time a text box is modified? Then just looping through the new table when saved? Not sure I know how to loop through that table though - updating if quantity is changed might be a bear too. If it considerably simplifies the process I could just remove the Repeater aspect and put separate GridViews on separate pages. Thanks!

• C# set custom UserControl variables when its in a Repeater

I thought I should be able to find uc by looking in the e.Item and then setting it somehow. I think this is the part where I'm missing something. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes["ParentItemID"] = i.ItemID.ToString(); } Any thoughts would be appreciated.

• ASP.NET Repeater, Dynamically starting new table row

  - by dherrin79

  I have the following repeater: <table> <asp:Repeater runat="server" ID="rptBrandRepeater"> <ItemTemplate> <tr> <td> <asp:HyperLink runat="server" ID="lnkCompanyLink"> <asp:Image runat="server" ID="imgCompanyLogo" /> </asp:HyperLink> </td> </tr> </ItemTemplate> </asp:Repeater> </table> I want to start a new row every four table cells. I don't want to used jQuery or Javascript to accomplish this. The outputted html is supposed to look like this page: http://rmtequipment.com/golfandturf.aspx I have made an interface that will allow them to add these logos on their own. So this page will be dynamically built. What is the best way to accomplish this goal? If a listview or gridview is a better approach I am open to that as well. Thanks in advance.
