  • ASP.Net: Expiring a page when navigating back

    - by K2so
    Basically all pages on this site I am building cannot be accessed when the user clicks on "Back" (or with key control) in the browser, and the page should expire if one is trying to navigate back in history. I put into Global.asax::Application_BeginRequest Response.Cache.SetCacheability(HttpCacheability.NoCache) Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1)) Response.Cache.SetValidUntilExpires(False) Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches) Response.Cache.SetNoStore() This would clear out the cache and disallow going back to any pages when the user is logged out, but doesn't do the job while the user is logged in. I saw posts where people suggested using a javascript approach, by calling History.Forward(1) on the page. But I wouldn't like to do this, as it will require javascript enabled to work (which user can disable). Appreciate any suggestions.

  • Passing additional data value to strongly typed partial views in ASP.NET MVC

    - by fearofawhackplanet
    I have an OrderForm domain class, which has property subclasses, something like: interface IOrderForm { int OrderId { get; } ICustomerDetails CustomerDetails { get; set; } IDeliveryDetails DeliveryDetails{ get; set; } IPaymentsDetails PaymentsDetails { get; set; } IOrderDetails OrderDetails { get; set; } } My "Details" view is strongly typed inheriting from IOrderForm. I then have a strongly type partial for rendering each section: <div id="CustomerDetails"> <% Html.RenderPartial("CustomerDetails", Model.CustomerDetails); %> </div> <div id="DeliveryDetails"> <% Html.RenderPartial("DeliveryDetails", Model.DeliveryDetails); %> </div> ... etc This works ok up to this point, but I'm trying to add some nice ajax bits for updating some parts of the order form, and I've realised that each of my partial views also needs access to the IOrderForm.OrderId. Whats the easiest way to give my partials access to this value?

  • ASP.NET Template Selector/Builder - Dynamic CMS

    - by Ugene
    I am currently building my own CMS for various reasons that could take a long to explain... However i am looking for a dynamic solution to create templates for pages within the CMS and all areas must be editable via the administration area, maybe large text areas broken into multiple areas, text and image area on a page etc. Following on from the above i would like to create the following: Create a new page (selecting a pre-defined template like below) http://img525.imageshack.us/img525/9872/nestedpages.png and then upon editing the page it would have created as many text editors required for each editable region or a file upload control for an image area for example. i am thinking of using nested masterpages for the design elements, just unsure the best-practice way to achieve the above (db structure etc) I somehow hope this provides enough information but are happy to answer any questions you may have. Thanks

  • Session State ArrayList in Shopping Cart ASP.NET

    - by user330342
    Hi guys, I'm creating a shopping cart application and I'm having some issues with implementing a session state for my arraylist. in my page load i declared if (Session["Cart"] == null) { Session["Cart"] = new ArrayList(); } else { ArrayList cart = (ArrayList)Session["Cart"]; } to create the session if it doesn't exist yet. then i have an event handler for a button to add items to the arraylist protected void onClick_AddBooking(object sender, EventArgs e) { int ClassID = Convert.ToInt32(Request.QueryString.Get("Class_Id")); ArrayList cart1 = new ArrayList(); cart1 = Session["Cart"]; cart1.Add(ClassID); i'm guessing i just don't know how to handle session states yet, thus the confusion. I'm essentially storing the class_ID then when the student confirms i'll store that to the DB and associate that ID with the Class Details. Thanks in advance guys!

  • Unable to bind in asp.net grid Template Column

    - by OneSmartGuy
    I am having trouble accessing the data field. I receive the error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. I can get the value but using <%# getOpenJobs((string)Eval("ParentPart")) % but I need to use it in the if to display a certian picture if it passes the condition. Is there a better way to do this or am i just missing something simple? <telerik:GridTemplateColumn UniqueName="hasOpenJobs" HeaderText=""> <ItemTemplate> <% if (getOpenJobs((string)Eval("ParentPart")) > 1) { %> <img src="../images/job-icon.gif" alt="Open Jobs" /> <%} %> </ItemTemplate> </telerik:GridTemplateColumn>

  • Hiding Url for asp.net page

    - by user204588
    Hello, I'm creating an html page that is posted to another page for processing. I don't want users to see the weird URL they are redirected to and I was using FRAMES but I can't figure out how to add my HTML page dynamically because I need the variables and either add frames or try another way to accomplish this. So, based on how I'm creating the page below, how can I hide the URL and add something that I want. Here is how I'm creating the page. StringBuilder sb = new StringBuilder(); sb.Append("<html><head></head>"); sb.Append("<body onload=\"document.frmLaunch.submit();\">"); sb.Append("<form name=\"frmLaunch\" action=\"" + variableTargetURL + "\" method=\"post\">"); sb.Append("<input type=hidden name=\"testVariable\" value=\"" + variableTest + "\">"); sb.Append("</form>"); sb.Append("</body></html>"); HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Write(sb.ToString()); response.End();

  • ASP.NET MVC model state as text

    - by David Moorhouse
    Is there an easy way to get a summary string of the errors that have been added to a controller's modelstate? I'm looking to return this in an Ajax method and want the validation errors etc to be returned to the client (i.e. the view does not exist for this method call). Or do I have to loop through the modelstate and look at each object and extract the error text manually?

  • Saving a modified object from ASP.NET MVC View Using Entity-Franework 4

    - by Dani
    I retrieve an object graph from DB using EF4. The context is closed as soon as the data retrieve and the data passes to the controller, and then to the view. in the view the data is modified, and then the controller gets it back. From the controller I run Repository.Update(MyEmp); and in my repository the code goes: using (var context = new mydb()) { if (myEmp.ID != 0) // Checking if it's modified or new { context.Emp.Attach(MyEmp); int result = context.SaveChanges(); return myEmp.ID; } } The problem - once attached, the object entityState goes to unchanged, and not modified, and of course - nothing is saved to the database. What am I doing wrong ?

  • Javascript check all checkboxes in a table / asp.net

    - by SLC
    I have a table with rows in, and each row has a few <td> elements. The last element has a checkbox in. They are in a <div> which is set to runat="server". I have another checkbox on the page called "chkAll" that when clicked, I want to javascript check or uncheck all of the checkboxes in my table. I'm not very good at Javascript, so I am not sure what to do. I added a javascript onclick method, and put document.getelementbyid and put in the div.clientID, but I wasnt sure what to do from there. Any ideas?

  • Cross Domain Cookies Problem (ASP.NET)

    - by Laserson
    Hi guys, i have a problem with cross-domain cookies. I read a lot of documentation about sharing cookies between subdomains. The main idea of all articles is set Domain property to something like ".mydomain.com". I've created two domains on local IIS server - test1.local.boo and test2.local.boo. They works great and visible with browser. I have the following code: Site test1 - Writes cookie: HttpCookie myCookie = new HttpCookie("TestCookie"); myCookie.Domain = ".local.boo"; myCookie["msg"] = "Welcome from Cookie"; Response.Cookies.Add(myCookie); Site test2 - Reads cookie: HttpCookie cookie = Request.Cookies["TestCookie"]; if (cookie != null) { Response.Write(cookie["msg"]); } else { Response.Write("FAILED"); } This code always shows FAILED message. So it means that second site can't read cookie from the same subdomain. Where is my mistake??

  • asp.net drop down list viewstate issue after client side Ajax update

    - by DSharper
    In my aspx page I have drop down list that initialy in page load event loads up with list of values which is shown to client(drop down list "A") and in client side, depending on client selecion of another drop down list(drop down list "B") I have written a javascript to update drop down list "A" with corresponding values with Ajax behaviour(without full page postback). But when we post page to the server, in server side page load event shows initialy sent list of values for drop down list "A" but not the values that were loaded by Ajax calls due to ViewState not being updated correctly due to Ajax call. I could fix this easily with update panel but it increased Ajax request size to 44KB which is much higher than what currently is for hand made Ajax script I have written( 0.5KB) Is there special way of fixing this rather than using update panel?

  • ASP MVC Creating Form Rows Dynamically

    - by Jonathan Stowell
    Hi Guys, I haven't even attempted this yet and am creating this question for advice really. I have a strongly typed page which receives a form model composed of several components. It is to create a mitigating circumstance (MC) for a student at a university for my final year project. A MC can be composed of the initial problem, assessment extensions, and I use a multi select box to allow the user to select staff retrieved from the database which are able to view the MC once created. The thing is I feel that a student could be granted many assignment extensions for one problem. I am wander if it is possible to include a button/image on the form which when clicked will create a new assessment extension object, and duplicate the form components to set the values for the object? This would all need to occur without any page refreshes. Any advice, or links to good tutorials would be appreciated. I have so far been unable to find any suitable examples. Thanks, Jon
