  • How to read the selected items in an Html.ListBox at postback time

    - by EasyTimer
    I have a search page on my MVC site that contains a list of strings that I think the user might wish to search for in my database. This list of strings is available in my model class, so I can populate an Html.ListBox with those strings thus: <%=Html.ListBox("SearchStrings", new SelectList(Model.SearchStrings)) % My problem is, how can I tell which strings the user selected in that list in my postback action? Any help would be most appreciated.

  • Calling jquery function from ascx not working

    - by Metju
    Hi Guys, I'm having a problem with the following situation. I have an ascx which contains a submit button for a search criteria and I am trying to call a validation function in a js file I've used throughout the site (this is the first time I'm using it in an ascx). Now I've just tried this: <script type="text/javascript" src="js/jquery-1.3.2.js"></script> <script type="text/javascript" src="js/jsAdmin_Generic_SystemValidation.js"></script> <script type="text/javascript"> $(document).ready(function () { $(".submitBtn").click(function (e) { alert("test"); alert($.Validate()); alert("test 2"); }); }); </script> The file is being referenced correctly as I am already seeing posts in Firebug that are done by it. This is the function: jQuery.extend({ Validate: function () { does validation... }); Now at first I was getting "Validate() is not a function" in firebug. Since I did that alert testing, I am getting the first alert, then nothing with no errors. Can anyone shed some light? Thanks

  • Html.DescriptionFor<T>

    - by Stacey
    I'm trying to emulate the Html Helper for "LabelFor" to work with the [Description] Attribute. I'm having a lot of trouble figuring out how to get the property from the helper though. This is the current signature... class Something { [Description("Simple Description")] [DisplayName("This is a Display Name, not a Description!")] public string Name { get; set; } } public static MvcHtmlString DescriptionFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression);

  • Intermittent error thrown, "A required anti-forgery token was not supplied or was invalid."

    - by Dave K
    I'm occasionally getting this error during normal use, and I've not found a way to stop it without removing the attribute that requires the token, which I'd rather not do. I've gotten this bug during my own testing (but seemingly randomly) and I know from my logging that actual logged-in users are getting it as well. Does anyone know what would cause the antiforgerytoken system to break (other than a real attack), and how I could fix this without opening up a security hole in my forms? Thanks!

  • Can I split system.serviceModel into a separate .config file?

    - by Mr Bell
    I want to separate my system.serviceModel section of the web.config into a separate file to facilitate some environment settings. My efforts have been fruitless. When I attempt it using this method. The wcf code throws an exception: "The type initializer for 'System.ServiceModel.ClientBase 1 threw an exception. Can anyone tell me what I am doing wrong? Web.config: <configuration> <system.serviceModel configSource="MyWCF.config" /> ....

  • Need to determine if ELMAH is logging an unhandled exception or one raised by ErrorSignal.Raise()

    - by Ronnie Overby
    I am using the Elmah Logged event in my Global.asax file to transfer users to a feedback form when an unhandled exception occurs. Sometimes I log other handled exceptions. For example: ErrorSignal.FromCurrentContext().Raise(new System.ApplicationException("Program code not found: " + Student.MostRecentApplication.ProgramCode)); // more code that should execute after logging this exception The problem I am having is that the Logged event gets fired for both unhandled and these handled, raised exceptions. Is there a way to determine, in the Logged event handler, whether the exception was raised via ErrorSignal class or was simply unhandled? Are there other Elmah events that I can take advantage of?

  • SyndicationItem.Content in .NET

    - by user102533
    Is there a reason I can get the Summary but not the Content of a SyndicationItem. I am looking for the entire post. It appears that it depends on how the RSS feed is configured. Is this true? Can I expect to read the entire content of any RSS feed from the wild? Thanks

    Hi I've got a DNN application using Telerik RadGrid. We're exporting some data from the Grid but when we drill down on the grid control and export the data we only see the initial top level data, never the updated Grid.

  • How to download .txt file from a url?

    - by Colin Roe
    I produced a text file and is saved to a location in the project folder. How do I redirect them to the url that contains that text file, so they can download the text file. CreateCSVFile creates the csv file to a file path based on a datatable. Calling: string pth = ("C:\\Work\\PG\\AI Handheld Website\\AI Handheld Website\\Reports\\Files\\report.txt"); CreateCSVFile(data, pth); And the function: public void CreateCSVFile(DataTable dt, string strFilePath) { StreamWriter sw = new StreamWriter(strFilePath, false); int iColCount = dt.Columns.Count; for (int i = 0; i < iColCount; i++) { sw.Write(dt.Columns[i]); if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); // Now write all the rows. foreach (DataRow dr in dt.Rows) { for (int i = 0; i < iColCount; i++) { if (!Convert.IsDBNull(dr[i])) { sw.Write(dr[i].ToString()); } if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); } sw.Close(); Response.WriteFile(strFilePath); FileInfo fileInfo = new FileInfo(strFilePath); if (fileInfo.Exists) { //Response.Clear(); //Response.AddHeader("Content-Disposition", "attachment; filename=" + fileInfo.Name); //Response.AddHeader("Content-Length", fileInfo.Length.ToString()); //Response.ContentType = "application/octet-stream"; //Response.Flush(); //Response.TransmitFile(fileInfo.FullName); } }

  • How to enable ajax when deriving from System.Web.UI.WebControls.WebControl on controls that are crea

    - by Dave
    I've built a class that derives from System.Web.UI.WebControl. It basically renders pagination links (same as what you see on top of GridView when enabled) for use above a repeater. I'm creating some anchor tags explicitly inside my nav control obviously, but they don't perform ajax postbacks. My understanding is that ajax requires POSTS to work right? Well, these would be GETs which I think is the problem. Is there a way to achieve what I'm trying to do? Thanks!

The page exists, I can browse to it, view it in design view and do stuff. When the site is loaded in the browser, it works fine. Any ideas?
