  • ASP.NET UpdatePanel PostBacks

    - by Matthew
    I created a marker interface: public interface ISupportAJAXPostsBacks{} I added it to my Page.. public partial class MyWebForm : PageBase, ISupportAJAXPostsBacks I have this check in my PageBase class... if(this is ISupportAJAXPostsBacks) { ... do some stuff ... } If I step through via the debugger, "this is ISupportAJAXPostsBacks" evaluates to true for the initial page load, but evaluates to false when an UpdatePanel posts back on that same page. (scratches head) What is happening under the covers to cause this and what can I do about it?

    - by Kumar
    I have a page in which I am loading a user control dynamically as follows: Default.aspx: <cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </cc1:ToolkitScriptManager> <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder> Default.aspx.cs: protected void Page_Load(object sender, EventArgs e) { var ctrl = LoadControl("~/UserCtrl1.ascx"); ctrl.ID = "ucUserCtrl1"; PlaceHolder1.Controls.Add(ctrl); } Below is the code for UserCtrl1.ascx <asp:Label ID="Label1" runat="server"></asp:Label> <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Click" /> <br /> <asp:PlaceHolder ID="PlaceHolder2" runat="server"></asp:PlaceHolder> I am dynamically loading another user control when the Button1 is clicked UserCtrl1.ascx.cs protected void Button1_Click(object sender, EventArgs e) { Label1.Text = "UserControl - 1 button clicked!"; var ctrl = LoadControl("~/UserCtrl2.ascx"); ctrl.ID = "ucUserCtrl2"; PlaceHolder2.Controls.Add(ctrl); } Below is the markup for UserCtrl2.ascx <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Label ID="Label2" runat="server"></asp:Label> <asp:Button ID="Button2" runat="server" Text="Button2" OnClick="Button2_Click" /> </ContentTemplate> </asp:UpdatePanel> UserCtrl2.ascx.cs protected void Button2_Click(object sender, EventArgs e) { Label2.Text = "UserControl - 2 button clicked!"; } After the page loads when I click the Button1 in UserCtrl1 the click event fires and I am able to see the Label1 text. It also properly loads the UserCtrl2, but when I click the Button2 in UserCtrl2 the click event dosent fire and even worse when I click the Button2 twice the UserCtrl2 control dissappears from the page. How can I fix this?

  • changing asp .net web service namespace when already in productive state

    - by eloQ
    by some unfortunate events we published a web service with the tempuri-namespace a couple of months ago and no one did notice (not in our company, not the companies connecting to the web service) even though it's live since that time and lots of companies (~25 i guess) already access this web service. now i'm thinking of correcting that mistake and have the namespace fixed to a proper value. the only problem is: as soon as we would do it, all the programs and services connected to this web service would stop working. i can't really allow that to happen. is there any way to fix the namespace for future purpose or to have the web service operate under two namespaces as one web service? any tip at all what i could do to get rid of the tempuri-namespace and have it fixed without needing to synchronize the change with all the external companies? i'm all out of ideas, so any help would be much appreciated! thanks! I hope this question is alright here, first time user, found this through using search engines on my research and found tempuri.org related posts, just not the right one..

  • How to page multiple data sets in ASP.NET MVC

    - by REA_ANDREW
    On a single view I will have three sets of paged data. Which means for each model I will have The Objects The Page Index The Page Size My initial thought was for example: public class PagedModel<T> where T:class { public IList<T> Objects { get; set; } public int ModelPageIndex { get; set; } public int ModelPageSize { get; set; } } Then having a model which is to be supplied to the action as for example: public class TypesViewModel { public PagedModel<ObjectA> Types1 { get; set; } public PagedModel<ObjectB> Typed2 { get; set; } public PagedModel<ObjectC> Types3 { get; set; } } So if I then for example have the Index view inherit from the type: System.Web.Mvc.ViewPage<uk.co.andrewrea.forum.Web.Models.TypesViewModel> Now my initial aciton method for the index is simply: public ActionResult Index() { var forDisplayPurposes = new TypesViewModel(); return View(forDisplayPurposes); } If I then want to page, it is here where I am struggling to decide which action to take. Lets say that I select the next page of the Types2 PageModel. What should the action look like for this in order to return the new view showing the second page of the Types2 PageModel I was thinking possibly to duplicate the action but use it with POST [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(TypesViewModel model) { return View(model); } Is this a good way to approach it. I understand there is always Session, but I was just wondering how such a thing is achieved currently out there. If any best methods have been mutually accepted and things. So simply, one page with multiple paged models. How to persist the data for each using a wrapper model. Which way should you pass in the model and which way should you page the data, i.e. Form Post Lastly, I have seen the routes take this into account i.e. {controller}/{action}/{id}/{pageindex}/{pagesize} but this only accounts for one model and I do not really wwant to repeat the pagesize and pageindex values for the number of models I have inside the wrapper model. Thanks for your time!! Andrew

    - by Blankman
    Using jquery, when a button is clicked (server side), I want to append #button to the url. This will only be used when there is validation errors, I want the browser to scroll to the bottom where the button is.

  • Simple Modal with Autocomplete in ASP.NET

    - by DanielJaymes
    Hello, I am quite new to this so any help is very much appreciated. I am generating a modal pop using Simple Modal, this works ok. I now want to add jquery autocomplete to the element txtEmail. When I run the page outside of Simple Modal I can use Autocomplete, however when the page is loaded through Simple Modal it does not work. I have checked to ensure the element is loaded, and it is allowing me to change the text color, but I can not add autocomplete to it. The code is /** * @author Daniel */ jQuery(function($) { $("input.ema, a.ema").click(function(e) { e.preventDefault(); $("#osx-modal-content").modal({ appendTo: 'form', overlayId: 'osx-overlay', containerId: 'osx-container', closeHTML: '<div class="close"><a href="#" class="simplemodal-close">X</a></div>', minHeight: 80, opacity: 65, position: ['0', ], overlayClose: true, onOpen: OSX.open, onClose: OSX.close, onShow: OSX.show }); }); var OSX = { container: null, open: function(d) { var self = this; $.ajax({ url: "/Message/UserMessage/", type: 'GET', dataType: 'html', // <-- to expect an html response success: function(result) { var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); $('div#osx-modal-data').html(result).find("#txtEmail").css('color', '#c00'); if ($('div#osx-modal-data').find("#txtEmail").length) { // implies *not* zero $('div#osx-modal-data').find("#txtEmail").autocomplete(data); alert('We found img elements on the page using "img"'); } else { alert('No txtEmail elements found'); } } }); self.container = d.container[0]; d.overlay.fadeIn('slow', function() { $("#osx-modal-content", self.container).show(); $('div#osx-modal-title').html("Send Email"); var title = $("#osx-modal-title", self.container); title.show(); d.container.slideDown('slow', function() { setTimeout(function() { var h = $("#osx-modal-data", self.container).height() + title.height() + 20; // padding d.container.animate({ height: h }, 200, function() { $("div.close", self.container).show(); $("#osx-modal-data", self.container).show(); }); }, 300); }); }) }, close: function(d) { var self = this; d.container.animate({ top: "-" + (d.container.height() + 20) }, 500, function() { self.close(); // or $.modal.close(); }); }, show: function(d) { // $('div#osx-modal-data').find("#txtEmail").css('color', '#ccc') } }; });

  • IIS5, ASP.NET (3.5) Application and Visual Studio 2008

    - by Lakeshore
    I have a solution that was developed in VS 2008 that is configured to use IIS. I configure the Virtual directory in IIS the same way I have with other working solutions using IIS. When I either build and run the solution in VS 2008 or browse the virtual directory using IIS, I get the following error message. Internet Explorer cannot display the webpage What you can try: It appears you are not connected to the Internet, but you might want to try to reconnect to the Internet Retype the address Go back to the previous page. Most likely causes: You are not connected to the Internet The website is encountering problems There might be a typing error in the address. Why might this be?

  • ASP.Net MVC - which is the best approach for multi select grouping using JQuery Dialog

    - by Rajeesh
    This is my scenario I have an view(page) with list of items, a user could select single or multiple items from this page and click on a "Add to Group" button. Then a modal dialog(JQuery dialog) will be shown, from that he could select group, then press the add button. Which causes the items selected in the parent page is added to that particular group. So, which is the best way to pass the selected items to the modal pop-up? Though the query string ? - what happens if the no:of items selected is large, will the url support that much characters Keep the list in the parent page in a javascript variable and return the selected group from the modal pop-up? Or is there is any other better option? Thanks, Rajeesh

  • asp.net MVC ActionMethod causing null exception on parameter

    - by David Liddle
    I am trying to add filter functionality that sends a GET request to the same page to filter records in my table. The problem I am having is that the textbox complains about null object reference when a parameter is not passed. For example, when the person first views the page the url is '/mycontroller/myaction/'. Then when they apply a filter and submit the form it should be something like 'mycontroller/myaction?name=...' Obviously the problem stems from when the name value has not been passed (null) it is still trying to be bound to the 'name' textbox. Any suggestions on what I should do regarding this problem? UPDATE I have tried setting the DefaultValue attribute but I am assuming this is only for route values and not query string values ActionResult MyAction([DefaultValue("")] string name) //Action - /mycontroler/myaction ActionResult MyAction(string name) { ...do stuff } //View <div id="filter"> <% Html.BeginForm("myaction", "mycontroller", FormMethod.Get); %> Name: <%= Html.TextBox("name") %> .... </div> <table>...my list of filtered data

  • ASP.NET Ajax Error: Sys.WebForms.PageRequestManagerParserErrorException

    - by Phil Bennett
    My website has been giving me intermittent errors when trying to perform any Ajax activities. The message I get is Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' So its obviously some sort of server timeout or the server's just returning back mangled garbage. This generally, unfortunately not always, happens when the site has been idle for a while. Anybody else been able to overcome this? Thanks

  • ASP.NET DropDownList Replacement

    - by user302004
    Currently, I'm populating a drop down list when a file is created in a configurable folder. if (!downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.FullName)) Then, I add the file and remove "No Responses Available". However, if the same file is resubmitted (i.e., the file name is the same but the timestamp is different), then I want to remove the older entry and replace it with a new entry in the drop down list. I have the filename, so I go into the "else" block from the line of code above. From there, I'm checking to see if I have the same filename and a different creation time. if (downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.FullName) && downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.CreationTime) From here, I want to find the position, remove it, and add the new text. This approach isn't working. Can anyone offer an alternate approach?
