  • How do I get 2-way data binding to work for nested asp.net Repeater controls

    - by jimblanchard
    I have the following (trimmed) markup: <asp:Repeater ID="CostCategoryRepeater" runat="server"> <ItemTemplate> <div class="costCategory"> <asp:Repeater ID="CostRepeater" runat="server" DataSource='<%# Eval("Costs")%>'> <ItemTemplate> <tr class="oddCostRows"> <td class="costItemTextRight"><span><%# Eval("Variance", "{0:c0}")%></span></td> <td class="costItemTextRight"><input id="SupplementAmount" class="costEntryRight" type="text" value='<%# Bind("SupplementAmount")%>' runat="server" /></td> </tr> </ItemTemplate> </asp:Repeater> </div> </ItemTemplate> </asp:Repeater> The outer repeater's DataSource is set in the code-beside. I've snipped them, but there are Eval statements that wire up to the properties in the outer Repeater. Anyway, one of the fields in the inner Repeater needs to be a Bind instead of an Eval, as I want to get the values that the user types in. The SupplementAmount input element correctly receives it's value when the page loads, but on the other side, when I inspect the contents of the Costs List when the form posts back, the changes the user made aren't present. Thanks.

  • force users to logout

    - by lipkee85
    Currently I have a client and admin webpage. There are multiple users who will login to the client page. While in admin page, when I restored the database inside the admin page, I need to logout all the users who are currently login to the client page. Any ideas how it should be done? My current language using is classic ASP. If it can be done in ASP.NET, its fine too. Thanks.

  • Custom session state provider needed for DB storage?

    - by subt13
    I know this question is related to many others, but please bear with me. I am trying an experiment to store all information in database tables instead of the ASP.NET session. In ASP.NET 4 one can create a custom provider for session. So, again should I implement a Custom Session-State Provider or should I just disable session (in Web.config)? Thanks! From the comments my question can be misunderstood. Hopefully this tidbit will help clarify: I don't want to store the session in the database. I want to store information in the database that you would typically store in the session. One reason why: I don't want to carry around a session on every page, especially if that page doesn't care about 90 percent of the information in the session

  • Facebook Card Game? Which architecture?

    - by Ben
    I am developing a Facebook Card Game for my thesis and i am wondering which architecture fits best? I am going to develop the game using Silverlight + ASP.NET. On the one side the game should contain player vs. player card games. On the other there will be also a lot of contant similar to Mafia Wars(or any other game like that) where you just interact with the server (incl. database) I read a lot about ASP.NET MVC, Silverlight MVVM and that stuff. But what fits best for a game like that? Also i am not sure if i should go with Silverlight 4 already? I don't want to start the wrong way. I really appreciate your help.

  • Switching to FormViewMode.Edit is very slow

    - by Tim
    When i switch an ASP.Net Formview from readonly mode to edit mode it takes more than 6 seconds(from edit to readonly takes a split second). I have no idea whats the reason for it. The EditItemTemplate contains a lot of controls(table,textboxes,dropdownlists) but in fact not more than the ItemTemplate has. Yet i have even commented out the complete FormView.DataBound where the controls are data bounded but without significant change. My ASP.Net Web Apllication is using Ajax and the Formview is completely nested in an UpdatePanel. Any suggestions or assumptions for this behaviour?

  • Avoiding try/catch hell in my web pages

    - by Shaun_web
    I am writing an ASP.NET website, which is a new framework for me. I find that I have a try/catch block in literally every method of my codebehind. All these try/catch blocks do is catch the exception and then pop-up an error message to the user. Isn't there some sort of global error handler in ASP.NET? It's worth noting that my error handling is within control (ASCX) pages, and I would like a way to simply get each ASCX to handle its own errors without forcing all error handling just to a single master page or a redirect...

  • How to generate <a> tag from input fields

    - by NonProgrammer
    Using ASP.Net (in C#), I need to generate a tag that contains person's name, address, etc. I have barely any experience with ASP.NET (or .NET languages) and I am given this assignment. Could someone please guide me to correct path please? Link should look like this: https://example.com/PRR/Info/Login.aspx?SupplierId=36&RegisteredUserLogin=T000001&Mode=RegisteredLoginless&RegisteredModeFunction=AutoShowTotals&RegisteredModeFunction=AutoShowTotals&PayerCountry=FI&[email protected]&ExternalOrderId=1000123&ServiceId=286&Amount286=5000.00&PayerInfo286=T000001|10000123|type1|m&SuccessReturnURL=http://success.html&FailureReturnURL=http://failure.html&SuccessCallbackURL=http://youpay.com/p247/success.html&FailureCallbackURL=http://yourfailure.html following components/fields needs to be sent to API in order to pre-populate information for users: FirstName, LastName, SupplierID = integer, Person's userlogin (Should increment by 1. Example: person 1 = t00001. Person2 = t00002, etc.), PayerCountry, Email, amount For some reason, my management thinks that this is something a non-technical person can do! Any help would be appreciated! Thanks!

  • Loading user controls programatically into a placeholder (asp.net)

    - by Phil
    In my .aspx page I have; <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" AspCompat="True" %> <%@ Register src="Modules/Content.ascx" tagname="Content" tagprefix="uc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:PlaceHolder ID="Modulecontainer" runat="server"></asp:PlaceHolder> </div> </form> </body> </html> In my aspx.vb I have; Try Dim loadmodule As UserControl loadmodule = Me.LoadControl("~/modules/content.ascx") Modulecontainer.Controls.Add(loadmodule) Catch ex As Exception Response.Write(ex.ToString & "<br />") End Try The result is an empty placeholder and no errors. Thanks a lot for any assistance P.S after Fat_Tony's answer I changed the code to; Try Dim loadmodule As ASP.ContentModule loadmodule = CType(LoadControl("~\Modules\Content.ascx"), ASP.ContentModule) Modulecontainer.Controls.Add(loadmodule) Catch ex As Exception Response.Write(ex.ToString & "<br />") End Try But still no results unfortunately.

  • CMS (Web Application OR Windows Application)

    - by Raha
    I am a little bit puzzled about something. I am creating a ASP.NET MVC eCommerce application and currently I have written all the back end in ASP.NET MVC. I was thinking if its better to write all the management in WPF instead of HTML, as its probably even less prone to be exploited by hackers. I am a Windows user so I am not really bothered about using Linux/Mac at the moment so I am quite aware that having all the back-end written in HTML will allow users to have access to the admin area using other OS. I would like to see what are the advantages and disadvantages of having WPF to manage the content of the website as its probably much easier to develop and manage (think about Live Writer).

  • Shrink a cell (in an absolutely-positioned ASP.NET table) to fit its contents?

    - by Giffyguy
    My webpage currently looks like this: <asp:Table runat="server" style="position: absolute; left: 0%; top: 82%; right: 0%; bottom: 0%; width: 100%; height: 18%" CellPadding="0" CellSpacing="0" GridLines="Both"> <asp:TableRow> <asp:TableCell> Content1 </asp:TableCell> <asp:TableCell Width="2.5%"> </asp:TableCell> <asp:TableCell > Content2 </asp:TableCell> </asp:TableRow> </asp:Table> But I need it to look like this: "Content1" is of unknown size, and the table will have to adjust to fit it in, but without taking any unnecessary space away from "Content2." I can't use "display: table" because it isn't supported in IE7 and such, so I'm pretty much stuck using a regular table element unless there is something better out there that is supported in older browsers. Does anyone know how this can be accomplished?

  • Why do we need Web-Api? [closed]

    - by user437973
    I was just wondering what the deal is with Asp.net Web-Api. Why did we need a separate type of controller in order to facilitate varying content types for action results? Why wasn't this capability just baked into the ASP.Net MVC base controller? Anyway, I was just wondering if there was a compelling reason to use both types of controllers within the same project, assuming that the project was being freshly created, or if this project structure was due to an inherent technical limitation. Would it be possible to have ApiControllers fulfill the purpose of an MVC Controller in all cases by just serving HTML when that is the specified accept type? It just seems to me like a lot of unnecessary repetition to have to re-implement the same types of actions using both types of controllers if you want those actions to be available to your web application through the API and through the web interface.

  • asp.net - updatepannel can't read innerHTML?

    - by omega
    In my asp.net page, I have a jquery sortable accordian (in an update panel) I use so that clients can re-arrange items. Then to save it, users would click a button (thats created from jquery) and it would traverse through the accoridion in the DOM, and write the info to a asp control textbox. Then invoke the click function of a asp button control, which then reads that information and saves the data. But now I decided to simplify this step, and use html agility pack in c#, so users click the asp button control (inside an update panel), and then it would get the innerHTML of the accordian. But the problem is, the html it's getting is not the reflecting the changes a user can make to the accordion (i.e. re arranging it), it the same as when the DOM was ready on page load... But note that, using javascript to write the innerHTML to a textbox, then from the c# function, I can read the up to date html from the accordian. Does anyone know why this is happening and how to get the up to data html from the accordian in c#?

  • DevConnections Slides and Samples Posted

    - by Rick Strahl
    I’ve posted the slides and samples to my DevConnections Sessions for anyone interested. I had a lot of fun with my sessions this time around mainly because the sessions picked were a little off the beaten track (well, the handlers/modules and e-commerce sessions anyway). For those of you that attended I hope you found the sessions useful. For the rest of you – you can check out the slides and samples if you like. Here’s what was covered: Introduction to jQuery with ASP.NET This session covered mostly the client side of jQuery demonstrated on a small sample page with a variety of incrementally built up examples of selection and page manipulation. This session also introduces some of the basics of AJAX communication talking to ASP.NET. When I do this session it never turns out exactly the same way and this time around the examples were on the more basic side and purely done with hands on demonstrations rather than walk throughs of more complex examples. Alas this session always feels like it needs another half an hour to get through the full sortiment of functionality. The slides and samples cover a wider variety of topics and there are many examples that demonstrate more advanced operations like interacting with WCF REST services, using client templating and building rich client only windowed interfaces. Download Low Level ASP.NET: Handlers and Modules This session was a look at the ASP.NET pipeline and it discusses some of the ASP.NET base architecture and key components from HttpRuntime on up through the various modules and handlers that make up the ASP.NET/IIS pipeline. This session is fun as there are a number of cool examples that demonstrate the power and flexibility of ASP.NET, but some of the examples were external and interfacing with other technologies so they’re not actually included in the downloadable samples. However, there are still a few cool ones in there – there’s an image resizing handler, an image overlay module that stamps images with Sample if loaded from a certain folder, an OpenID authentication module (which failed during the demo due to the crappy internet connection at DevConnections this year :-}), Response filtering using a generic filter stream component, a generic error handler and a few others. The slides cover a lot of the ASP.NET pipeline flow and various HttpRuntime components. Download Electronic Payment Processing in ASP.NET Applications This session covered the business end and integration of electronic credit card processing and PayPal. A good part of this session deals with what’s involved in payment processing, getting signed up and who you have to deal with for your merchant account. We then took a look at integration of credit card processing via some generic components provided with the session that allow processing using a unified class interface with specific implementations for several of the most common gateway providers including Authorize.NET, PayFlowPro, LinkPoint, BluePay etc. We also briefly looked at PayPal Classic implementation which provides a quick and cheap if not quite as professional mechanism for taking payments online. The samples provide the Credit Card processing wrappers for the various gateway providers as well as a PayPal helper class to generate the PayPal redirect urls as well as helper code for dealing with IPN callbacks. Download Hope some of you will find the material useful. Enjoy.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

  • Un Web évangéliste de Microsoft critique avec humour la fin du support du H.264 dans Chrome et compare WebM à l'Espéranto

Google a motivé sa décision en indiquant qu'il souhaitait se concentrer uniquement sur les technologies ouvertes, et notamment WebM et Theora, deux codecs également soutenus par Mozilla et Opera (lire ci-avant). Tim Sneath, qui s'exprime en son nom propre, parodie cette argumentation en reprenant...
