  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • Why no ArgumentEmptyException in .NET ?

    - by Andrei Rinea
    I am beginning to think I am doing something wrong. I mean they did place System.String.IsNullOrWhitespace finally but no ArgumentEmptyException class. public FilterItem(string name, IEnumerable<string> extensions) { if (string.IsNullOrWhiteSpace(name)) { throw new ArgumentNullException("name"); } if (extensions == null) { throw new ArgumentNullException("extensions"); } if (extensions.Count() == 0) { throw new ArgumentOutOfRangeException("extensions"); } this.Name = name; this.Extensions = extensions; } throwing an ArgumentOutOfRangeException feels unnatural. Also an instance of ArgumentException is too general in my opinion. It's easy to me to create a new exception class call it this way and have it over with. What bugs me is that it's not in the BCL/FCL and I am beginning to think there's a good reason not to have it. Should there be one?

  • net c# lock statement in data access layer

    - by Pedro Rivera
    I saw a code where they have the data access layer like this: public class CustomerDA{ private static readonly object _sync = new object(); private static readonly CustomerDA _mutex = new CustomerDA(); private CustomerDA(){ } public CustomerDA GetInstance(){ lock(_sync){ return _mutex; } } public DataSet GetCustomers(){ //database SELECT //return a DataSet } public int UpdateCustomer(some parameters){ //update some user } } public class CustomerBO{ public DataSet GetCustomers(){ //some bussiness logic return CustomerDA.GetInstance().GetCustomers(); } } I was using it, but start thinking... "and what if had to build a facebook like application where there are hundreds of thousands of concurrent users? would I be blocking each user from doing his things until the previous user ends his database stuff? and for the Update method, is it useful to LOCK THREADS in the app when database engines already manage concurrency at database server level?" Then I started to think about moving the lock to the GetCustomers and UpdateCustomer methods, but think again: "is it useful at all?"

  • ASP.NET 4.0 webforms routing

    - by Ethan
    I have an existing site that I'd like to convert to use routing, and after reading Scott Guthrie's post here, I built a working sample that works for most circumstances. However, since not all of the pages on the existing site match a particular pattern, I'll need to check against a database to determine which route (destination .aspx page) to use. For example, most pages are like this: http://www.mysite.com/people/person.html This is fine - I can easily route these to the view_person.aspx page because of the 'people' directory. But some pages are like this: http://www.mysite.com/category_page.html http://www.mysite.com/product_page.html This necessitates checking the database to see whether to route to the view_category.aspx page or the view_product.aspx page. And this is where I'm stuck. Do I create an IRouteHandler that checks the database and returns the route? Or is there a better way? The only code I've found that kind of fits is the answer to this question. Thanks in advance.

  • ASP.NET Ajax partial postback and jQuery problem

    - by chromaloop
    A control contains some HTML and some jQuery to handle a fancy tooltip to display when you click an image within a div. The control is then used on several different pages, sometimes within an updatePanel, sometimes not. I have the following code to handle loading the jQuery after a partial postback when the control is displayed within an update panel. Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function EndRequestHandler(sender, args) { $('img.ormdShipping').each(function(){ $(this).qtip({ // some qtip options go here }) }); } Problem is, the jQuery doesn't load when the control is used anywhere other than an updatePanel. Do I need a second function that's triggered outside of the EndRequestHandler?

  • Asp Dot Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea?

  • asp.net mvc custom routes with multiple submit buttons

    - by dangerisgo
    So I have a custom route as such: routes.MapRoute( "Wizard", // Route name "Wizard/{page}", // URL with parameters new { controller = "Wizard", action = "Index" } // Parameter defaults ); and have the following on my View: <% Html.BeginForm("Continue", "Wizard"); %> <input type="submit" value="Continue" name="Continue" /> <% Html.EndForm(); %> In which I want to call this function: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Continue(string Number, string Rev) { (...) } but in turn when that button is pressed always calls the postback Index rather than the one I want. If I remove the custom route, it calls my function, but what I want to be displayed in the address bar is: localhost:xxxx/Wizard/1 where the number at the end is the page (div shown) of the wizard either 1, 2, 3, or 4. So is there something I'm missing or can it not be done? Thanks.

  • .NET WebService Security who can see and use.

    - by user295734
    Trying to firgure out how to test the security of a WebService. Is there some way to search a site for webservices? I have 2 applications one has a webservice and the other a reference to that service. I let visual studio build the reference in the App_WebReferences folder. The webservice works, but i started wondering, can anyone access this service from any website? If so, how can i test this? How do you search a site for webservices? Could I use jQuery/JSON code from a simple site to access a webservice? I guess if it is not secure, how do you secure a webservice?

  • ASP.NET: ModalPopupExtender prevents button click event from firing

    - by C. Griffin
    Here is what I'm trying to do: Click a button on my page, which in turn makes (2) things happen: Display a ModalPopup to prevent the user from pressing any buttons or changing values Call my code behind method, hiding the ModalPopup when finished Here is the ASP markup: <asp:UpdatePanel ID="UpdatePanel2" runat="server" ChildrenAsTriggers="true" UpdateMode="Always"> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnSaveData" EventName="Click" /> </Triggers> <ContentTemplate> <asp:Panel ID="pnlHidden" runat="server" style="display: none;"> <div> <h1>Saving...</h1> </div> </asp:Panel> <cc1:ModalPopupExtender ID="modalPopup" BackgroundCssClass="modalBackground" runat="server" TargetControlID="btnSaveData" PopupControlID="pnlHidden"> </cc1:ModalPopupExtender> <asp:Button ID="btnSaveData" runat="server" Text="Save Data" OnClick="btnSaveData_Click" /> </ContentTemplate> </asp:UpdatePanel> Now, here is my code behind C# code: protected void btnSaveData_Click(object sender, EventArgs e) { UpdateUserData(GetLoggedInUser()); modalPopup.Enabled = false; } Why doesn't this work? The ModalPopup displays perfectly, but the btnSaveData_Click event NEVER fires.
