  • Javascript update before page loads in ASP.NET

    - by user204588
    Hello, I'm trying to update values from a xml file into textboxes. I have this javascript being called in the Page_Load event this.Page.ClientScript.RegisterStartupScript(this.GetType(), "Script", sb.ToString(), true); I click the continue button which does a post back but the values are not updated until I refresh the page again which makes me think the js isn't being run until after the page is returned. I'm wondering how to have the values updated when the page is refreshed after the button postback. thanks

  • Runtime Error in asp.net?(online )

    - by Surya sasidhar
    hi, I develop a web application it is working fine in local. When i upload the site in online through CuteFTP it is showing the error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. please help me i place the but even though it is not working it is giving same error. Thank you

  • 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();

  • How do i provide a custom session ID getter/setter in asp.net

    - by Monsters
    I want to pass the sessionID as a json parameter, I can see how to override SessionIDManager and such, but this just covers custom creation/validation of sessionID's as opposed to where it actually gets the sessionID from. There is of course 'cookieless' which puts it in the url, but that doesn't work for me either. So i'd like to override the session handling so I can specify where it should look for the sessionID.

  • 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?

  • Form with list of checkboxes (best practices)

    - by boris callens
    I have a view that allows the user to make a selection from an IEnumerable. The way I'm doing it now is to give each checkbox the id of the item and work with the form collection at the controller's side. I seem to remember there to be a better way but can't remember how anymore. Are there any better practices?

Why is that and how can I cache the images for the next year.

  • ASP.NET Custom Control With A Property That Is An Interface

    - by user129674
    I want to have a property on my custom control that is an interface type. For example: [ ToolboxData("<{0}:MyTextBox runat=server></{0}:MyTextBox"), ParseChildren(true, "Validation") ] class MyTextBox : WebControl { [ Category("Behavior"), Description("The validation to use"), DesignerSerializationVisibility(DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerDefaultProperty) ] public IValidation Validation { get; set; } } Then when I go to use my control in a web form I would like to be able to do: <my:MyTextBox ID="txt" runat="server"> <my:FancyValidator /> </my:MyTextBox> That way I will be able to define one class that could use any number of validators. When I try and do this now, I end up with an error saying: Type 'IValidator' does not have a public property named 'FancyValidator' What do I need to do to make this work? Thanks!

  • 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.

  • 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??

  • Persistent Objects in ASP.NET

    - by user204588
    Hello, I'm trying to find the best way to persist an object or in use the same object at a later point in the code. So, I create an object, then you're redirected to another page(a form) that needs to use variables from that object. That form is submitted to a third party and there is stuff done on their end and then they request a page on my application that runs some more code and needs the objects variables again. I thought about Database but this is all done at once. This is done during a user checkout process and after it's over, there's no reason to retrieve this object again. So adding and retrieving from a database seems like it would be overkill and I think it would make the process slower. Right now I'm using Session but I keep hearing not to use that but no one is really saying why I shouldn't except it is bad practice. I can't really use post back values because the pages don't work that way. The checkout process starts off in a dll code that redirects to the form that is submitted to the third party and the a page is requested by the third party. So, I'm not really sure of the best way. What are all the options and what does everyone recommend as the best way?

  • ASP.NET UserControl Caching

    - by Adam
    Hi, This thing is driving me nuts. I have a UserControl that is called WebUserControl. I need to cache this control, so I put the following in the WebUserControl.ascx: <%@ OutputCache Duration="240" VaryByParam="FeedName" %> Then I have the Default.aspx file in which I have: <div class="divInnerLeft" id="L1" runat="server"> <uc1:WebUserControl FeedId="a1" ID="a1" runat="server" FeedName=""/> </div> <div class="divInnerMiddle" id="M1" runat="server"> <uc1:WebUserControl FeedId="a3" ID="a3" runat="server" FeedName=""/> </div> In the Page_Load event I set the FeedName property - according to the user preferences. The problem is that after initially loading the page, the controls are generated OK. But then, in the Page_Load event they are not available again. So the a1 and a3 are null and I cannot set the FeedName for different user. How to solve this? Thanks!

  • ASP.NET - Google Chrome caching DropDownList selections

    - by Fake
    I'm experiencing what seems to be a caching issue with Google Chrome and Safari on my cart page. In the cart there are 2 dropdown lists. When you hit the checkout button after changing the values in the dropdown lists, it commits what's selected in the lists to the database. It's a little bit hard to explain the unexpected behavior so I will try to write it out step by step with an illustration of my problem. Lets say the first dropdown list has the values of: VALUE1 VALUE2 VALUE3 And the second dropdown list has the values of: DUMBO1 DUMBO2 DUMBO3 I add an item to my cart. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I hit Checkout. Database says: VALUE1, DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) I hit the back button. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I drop down the VALUE1 combo and select VALUE2, VALUE2 is selected momentarily and then the site posts back and VALUE1 is re-selected in the drop down list (from being reloaded from the DB) MOMENTARILY Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 THEN AFTER POSTBACK FROM DROPDOWNLIST_SELECTIONCHANGED EVENT Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 Hit Checkout. Database Says VALUE1 ,DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) Go back. Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 So it appears that it's remembering my selection of VALUE2 even though it jumped back to VALUE1 before I checked out. It seems to be a caching problem, however I've got some no-cache code to prevent caching of that page that works great in firefox and internet explorer but seems to be failing in Chrome and Safari. I'm basically returning in the headers for the cart page: no-cache, no-store, and must-revalidate to attempt to prevent caching, but based on this scenario it seems to be caching the page anyway and not reloading it when I hit the back button. I am open to any solutions or suggestions at this point. Thanks!
