  • How can a multi-select-list be edited using asp.net mvc?

    - by Anders Juul
    I'd like to edit an object like the one below. I'd like the UsersSelectedList populated with one or more Users from the UsersGrossList. Using the standard edit-views in mvc, I get only strings and booleans (not shown below) mapped. Many of the examples I find on google utilizes early releases of the mvc framework whereas I use the official 1.0 release. Any examples of the view is appreciated. public class NewResultsState { public IList<User> UsersGrossList { get; set; } public IList<User> UsersSelectedList { get; set; } }

  • How do I install an ASP.Net MVC application on IIS 7 using Wix?

    - by Simon Steele
    For IIS6 I can use the IIS helpers in Wix to install a web application like this: <iis:WebAppPool Id="AP_MyApp" Name="My Application Pool" Identity="networkService" /> <iis:WebApplication Id="WA_MyApp" Name="MyApp" WebAppPool="AP_MyApp"> <iis:WebApplicationExtension CheckPath="no" Executable="[NETFRAMEWORK20INSTALLROOTDIR]aspnet_isapi.dll" Verbs="GET,HEAD,POST"/> </iis:WebApplication> Unfortunately, this doesn't work for IIS7. We don't want to use the aspnet_isapi.dll mechanism, and instead want the integrated pipeline to handle the request routing. The app pool created by this script is in Classic mode not Integrated mode so none of the handlers get run correctly. How can I correctly install an MVC app on IIS 7?

  • 'Please wait' screen between pages in C# ASP.NET. Best practice?

    - by Glinkot
    Hi, I have a gridview with some imagebuttons, each of which kicks off a report page for that item. The report take 10-15 seconds to run, so I'd like a popup 'Generating report, please wait' type thing. I can think of a few ways but would like the opinion of those more experienced than I. The options I was considering: a) link my imagebutton to an intermediate page that says 'please wait', and then refer it onto the report page from there. Seems a bit clunky b) Investigate using jquery or similar. I have telerik controls, they have a few things but it isn't clear if any are suitable. c) Define some kind of CSS layer with a please wait warning on it, and make it visible as part of the button's onclick event d) Look into jquery or similar Any thoughts? Thanks!

  • How can I validate the result in an ASP.NET MVC editor template?

    - by Morten Christiansen
    I have created an editor template for representing selecting from a dynamic dropdown list and it works as it should except for validation, which I have been unable to figure out. If the model has the [Required] attribute set, I want that to invalidate if the default option is selected. The view model object that must be represented as the dropdown list is Selector: public class Selector { public int SelectedId { get; set; } public IEnumerable<Pair<int, string>> Choices { get; private set; } public string DefaultValue { get; set; } public Selector() { //For binding the object on Post } public Selector(IEnumerable<Pair<int, string>> choices, string defaultValue) { DefaultValue = defaultValue; Choices = choices; } } The editor template looks like this: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <select class="template-selector" id="<%= ViewData.ModelMetadata.PropertyName %>.SelectedId" name="<%= ViewData.ModelMetadata.PropertyName %>.SelectedId"> <% var model = ViewData.ModelMetadata.Model as QASW.Web.Mvc.Selector; if (model != null) { %> <option><%= model.DefaultValue %></option><% foreach (var choice in model.Choices) { %> <option value="<%= choice.Value1 %>"><%= choice.Value2 %></option><% } } %> </select> I sort of got it to work by calling it from the view like this (where Category is a Selector): <%= Html.ValidationMessageFor(n => n.Category.SelectedId)%> But it shows the validation error for not supplying a proper number and it does not care if I set the Required attribute.

  • How can you inject an asp.net (mvc2) custom membership provider using Ninject?

    - by AlDev
    OK, so I've been working on this for hours. I've found a couple of posts here, but nothing that actually resolves the problem. So, let me try it again... I have an MVC2 app using Ninject and a custom membership provider. If I try and inject the provider using the ctor, I get an error: 'No parameterless constructor defined for this object.' public class MyMembershipProvider : MembershipProvider { IMyRepository _repository; public MyMembershipProvider(IMyRepository repository) { _repository = repository; } I've also been playing around with factories and Initialize(), but everything is coming up blanks. Any thoughts/examples?

  • How I can export a datatable to MS word 2007, excel 2007,csv from asp.net?

  • How to use HtmlEncode with TemplateFields, Data Binding, and a GridView

    - by Yadyn
    I have a GridView bound to an ObjectDataSource. I've got it supporting editing as well, which works just fine. However, I'd like to safely HtmlEncode text that is displayed as we do allow special characters in certain fields. This is a cinch to do with standard BoundFields, as I just set HtmlEncode to true. But in order to setup validation controls, one needs to use TemplateFields instead. How do I easily add HtmlEncoding to output this way? This is an ASP.NET 2.0 project, so I'm using the newer data binding shortcuts (e.g. Eval and Bind). What I'd like to do is something like the following: <asp:TemplateField HeaderText="Description"> <EditItemTemplate> <asp:TextBox ID="TextBoxDescription" runat="server" Text='<%# System.Web.HttpUtility.HtmlEncode(Bind("Description")) %>' ValidationGroup="EditItemGrid" MaxLength="30" /> <asp:Validator ... /> </EditItemTemplate> <ItemTemplate> <asp:Label ID="LabelDescription" runat="server" Text='<%# System.Web.HttpUtility.HtmlEncode(Eval("Description")) %>' /> </ItemTemplate> </asp:TemplateField> However, when I try it this way, I get the following error: CS0103: The name 'Bind' does not exist in the current context

  • How to handle Booleans/CheckBoxes in ASP.NET MVC 2 with DataAnnotations?

    - by asp_net
    I've got a view model like this: public class SignUpViewModel { [Required(ErrorMessage = "Bitte lesen und akzeptieren Sie die AGB.")] [DisplayName("Ich habe die AGB gelesen und akzeptiere diese.")] public bool AgreesWithTerms { get; set; } } The view markup code: <%= Html.CheckBoxFor(m => m.AgreesWithTerms) %> <%= Html.LabelFor(m => m.AgreesWithTerms)%> The result: No validation is executed. That's okay so far because bool is a value type and never null. But even if I make AgreesWithTerms nullable it won't work because the compiler shouts "Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions." So, what's the correct way to handle this?

  • Are you as productive in Javascript as you are in .Net or Java?

    - by bglenn
    I code primarily in javascript and in vb.net. I've found that if I can achieve the same thing in both javascript and vb.net that I feel far more productive and expressive using javascript for the task. I often find myself researching server-side javascript implementations to see if anything has gone mainstream so that I can code my back-end business logic and data access in javascript. Given all the advanced tooling and language features in .Net this preference seems somewhat paradoxical to me. I'm not suggesting one is better than the other (I've been a vb programmer since I started programming), I'm just wondering if my preference is entirely subjective or if anyone else shares it. So, does anyone else enjoy coding in javascript to the point where you prefer it to the .Net and Java environment, and if, so why?

  • Asp.net Mvc 2: Repository, Paging, and Filtering how to?

    - by Dr. Zim
    It makes sense to pass a filter object to the repository so it can limit what records return: var myFilterObject = myFilterFactory.GetBlank(); myFilterObject.AddFilter( new Filter { "transmission", "eq", "Automatic"} ); var myCars = myRepository.GetCars(myfilterObject); Key question: how would you implement paging and where? Any links on how to return a LazyList from a Repository as it would apply here? Would this be part of the filter object? Something like: myFilterObject.AddFilter( new Filter { "StartAtRecord", "eq", "45"} ); myFilterObject.AddFilter( new Filter { "GetQuantity", "eq", "15"} ); var myCars = myRepository.GetCars(myfilterObject); I assume the repository must implement filtering, otherwise you would get all records.

  • How would you validate a checkbox in ASP.Net MVC 2?

    - by Scott Mayfield
    Using MVC2, I have a simple ViewModel that contains a bool field that is rendered on the view as a checkbox. I would like to validate that the user checked the box. The [Required] attribute on my ViewModel doesn't seem to do the trick. I believe this is because the unchecked checkbox form field is not actually transmitted back during the POST, and therefore the validation doesn't run on it. Is there a standard way to handle checkbox "required" validation in MVC2? or do I have to write a custom validator for it? I suspect the custom validator won't get executed either for the reason mentioned above. Am I stuck checking for it explicitly in my controller? That seems messy... Any guidance would be appreciated.

  • How do I use a datetime variable with createparameter in classic ASP?

    - by Frank Schmitt
    I'm having a heck of a time trying to create a parameterized query that binds a date variable into a stored procedure call: twoyearsago = dateadd("yyyy", -2, date()) DataConn.ConnectionString = myConnectionString DataConn.Open Set rs = Server.CreateObject("ADODB.Recordset") Set DataCmd = Server.CreateObject("ADODB.Command") DataCmd.ActiveConnection = DataConn DataCmd.CommandText = "exec myStoredProc ?, ?" DataCmd.Parameters.Append DataCmd.CreateParameter("@start", adDate, , 10, date()) DataCmd.Parameters.Append DataCmd.CreateParameter("@end", adDate, , 10, twoyearsago) rs.Open DataCmd The stored proc returns nothing (indicating the dates aren't making it through). If I hard code dates in the query, e.g.: DataCmd.CommandText = "exec myStoredProc '01/01/2008', '01/01/2010'" I get the results I would expect. Calling CStr on my dates (if that makes a difference) returns them in the above format.

  • Receiving "Path 'OPTIONS' is forbidden." Exception in ASP.NET website

    - by Greg
    I am getting the error "Path 'OPTIONS' is forbidden." since we moved our website over to a new server setup. I am unable to recreate the error but I am receiving emails for this exception at least a few times a day. Any ideas what could be causing this and how I can fix it? EDIT: Stack Trace: at System.Web.HttpMethodNotAllowedHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) There are no directories or files named OPTIONS and I believe all permissions are correct. I am finding some information about a possible link to EXCEL getting data from the webserver, but nothing that full explains how or what is happening yet. EDIT AGAIN: Seems this has to do with Excel files opening in Internet Explorer..

  • Using HtmlAnchor for anchor tag that navigates in-page named anchor

    - by Frank Schwieterman
    I am trying to render a simple hyperlink that links to a named anchor within the page, for example: <a href="#namedAnchor"scroll to down</a <a name="namedAnchor"down</a The problem is that when I use an ASP.NET control like asp:HyperLink or HtmlAnchor, the href="#namedAnchor" is rendered as href="controls/#namedAnchor" (where controls is the subdirectory where the user control containing the anchor is). Here is the code for the control, using two types of anchor controls, which both have the same problem: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Test.ascx.cs" Inherits="TestWebApplication1.controls.Test" % <a href="#namedAnchor" runat="server"HtmlAnchor</a <asp:HyperLink NavigateUrl="#namedAnchor" runat="server"HyperLink</asp:HyperLink The generated source looks like: <a href="controls/#namedAnchor"HtmlAnchor</a <a href="controls/#namedAnchor"HyperLink</a I really just want: <a href="#namedAnchor"HtmlAnchor</a <a href="#namedAnchor"HyperLink</a I am using the HtmlAnchor or HyperLink class because I want to make changes to other attributes in the code behind. I do not want to introduce a custom web control for this requirement, as the requirement I'm pursuing is not that important and it would be hard to talk the team into abandoning the traditional ASP.NET link controls. It seems like I should be able to use the ASP.NET link controls to generate the desired link.

  • Asp.Net MVC Data Annotations. How to get client side validation on 2 properties being equal

    - by Mark
    How do you get client side validation on two properties such as the classic password confirm password scenario. I'm using a metadata class based on EF mapping to my DB table, heres the code. The commented out attributes on my class will get me server side validation but not client side. [MetadataType(typeof(MemberMD))] public partial class Member { //[CustomValidation(typeof(MemberMD), "Verify", ErrorMessage = "The password and confirmation password did not match.")] //[PropertiesMustMatch("Password", "ConfirmPassword", ErrorMessage = "The password and confirmation password did not match.")] public class MemberMD { [Required(ErrorMessage = "Name is required.")] [StringLength(50, ErrorMessage = "No more than 50 characters")] public object Name { get; set; } [Required(ErrorMessage = "Email is required.")] [StringLength(50, ErrorMessage = "No more than 50 characters.")] [RegularExpression(".+\\@.+\\..+", ErrorMessage = "Valid email required e.g. [email protected]")] public object Email { get; set; } [Required(ErrorMessage = "Password is required.")] [StringLength(30, ErrorMessage = "No more than 30 characters.")] [RegularExpression("[\\S]{6,}", ErrorMessage = "Must be at least 6 characters.")] public object Password { get; set; } [Required] public object ConfirmPassword { get; set; } [Range(0, 150), Required] public object Age { get; set; } [Required(ErrorMessage = "Postcode is required.")] [RegularExpression(@"^[a-zA-Z0-9 ]{1,10}$", ErrorMessage = "Postcode must be alphanumeric and no more than 10 characters in length")] public object Postcode { get; set; } [DisplayName("Security Question")] [Required] public object SecurityQuestion { get; set; } [DisplayName("Security Answer")] [Required] [StringLength(50, ErrorMessage = "No more than 50 characters.")] public object SecurityAnswer { get; set; } public static ValidationResult Verify(MemberMD t) { if (t.Password == t.ConfirmPassword) return ValidationResult.Success; else return new ValidationResult(""); } } Any help would be greatly appreciated, as I have only been doing this 5 months please try not to blow my mind.

  • Can't set LinqDataSource InsertParameters from my code behind.

  • ASP.NET MVC Ajax Form: Is enctype correct? Why doesn't file get uploaded?

    - by Fabio Milheiro
    In the case that the user doesn't have Javascript activated, in order to draw a form, I begin this way: <% using (Html.BeginForm("Create", "Language", FormMethod.Post, new {enctype="multipart/form-data"})) { %> If the user has Javascript activated, the following code is used: <% using (Ajax.BeginForm("Create", "Language", new AjaxOptions { UpdateTargetId = "CommonArea" }, new { enctype = "multipart/form-data" })) { %> The problem is this: In the first case, I can get the file uploaded using the following instruction in the business layer: // Get the uploaded file HttpPostedFile Flag = HttpContext.Current.Request.Files["Flag"]; In the second case, this instruction doesn't work. How do I know upload that file using the Ajax.BeginForm? Is the code right? Can anyone more experience advise about using jQuery plug-in to upload file before the form submission? Thank you

  • How to use relative URL in jqGrid url parameter in ASP MVC?

    - by Chris Herring
    I've setup a jqGrid like this $('#gridTable').jqGrid({ url: '/GridData/', ... Now if I navigate to a url such as "/Controller/id/" then the grid will send a GET to "/GridData/" instead of "/Controller/id/GridData/". Can I make the GET relative so that I can pick the id up on the server side or do I have to manually pass the id as a parmater using javascript on the client?

  • ASP.NET MVC - using model property as form, how can I post to action?

    - by Ryan Peters
    Consider the following model: public class BandProfileModel { public BandModel Band { get; set; } public IEnumerable<Relationship> Requests { get; set; } } and the following form: <% using (Html.BeginForm()) { %> <%: Html.EditorFor(m => m.Band) %> <input type="submit" value="Save Band" /> <% } %> which posts to the following action: public ActionResult EditPost(BandProfileModel m, string band) { // stuff is done here, but m is null? return View(m); } Basically, I only have one property on my model that is used in the form. The other property in BandProfleModel is just used in the UI for other data. I'm trying to update just the Band property, but for each post, the argument "m" is always null (specifically, the .Band property is null). It's posting just fine to the action, so it isn't a problem with my route. Just the data is null. The ID and name attributes of the fields are BAND_whatever and Band.whatever (whatever being a property of Band), so it seems like it would work... What am I doing wrong? How can I use just one property as part of a form, post back, and have values populated via the model binder for my BandProfileModel property in the action? Thanks.

  • SelectedIndexChanged for programmatically created dropdownlist in ASP.NET fires multiple times.

    - by Achilles
    Consider the following: dim dropdownlist1 as new dropdownlist dim dropdownlist2 as new dropdownlist dim dropdownlist3 as new dropdownlist dropdownlist1.AutoPostBack = true dropdownlist2.AutoPostBack = true dropdownlist3.AutoPostBack = true AddHandler dropdownlist1.SelectedIndexChanged, AddressOf SomeEvent AddHandler dropdownlist2.SelectedIndexChanged, AddressOf SomeEvent AddHandler dropdownlist3.SelectedIndexChanged, AddressOf SomeEvent The SomeEvent fires as expected when any of the dropdown's selection is changed. However if say DropdownList2 has a selection made then I make a selection with either DropDownList1 or DropdownList3, then SomeEvent fires again. What is causing this behavior and how do I get just a single raising of that event? I suspect that when the viewstate for the dynamcially created dropdownlists is restored and the selection restored, then the event is fired because technically the selected index did change when the control was recreated. The reason I suspect this is that the event fires the for each dropdownlist...

  • ASP.NET Creating a Rich Repeater, DataBind wiping out custom added controls...

    - by tonyellard
    So...I had this clever idea that I'd create my own Repeater control that implements paging and sorting by inheriting from Repeater and extending it's capabilities. I found some information and bits and pieces on how to go about this and everything seemed ok... I created a WebControlLibrary to house my custom controls. Along with the enriched repeater, I created a composite control that would act as the "pager bar", having forward, back and page selection. My pager bar works 100% on it's own, properly firing a paged changed event when the user interacts with it. The rich repeater databinds without issue, but when the databind fires (when I call base.databind()), the control collection is cleared out and my pager bars are removed. This screws up the viewstate for the pager bars making them unable to fire their events properly or maintain their state. I've tried adding the controls back to the collection after base.databind() fires, but that doesn't solve the issue. I start to get very strange results including problems with altering the hierarchy of the control tree (resolved by adding [ViewStateModeById]). Before I go back to the drawing board and create a second composite control which contains a repeater and the pager bars (so that the repeater isn't responsible for the pager bars viewstate) are there any thoughts about how to resolve the issue? In the interest of share and share alike, the code for the repeater itself is below, the pagerbars aren't as significant as the issue is really the maintaining of state for any additional child controls. (forgive the roughness of some of the code...it's still a work in progress) using System; using System.Collections.Generic; using System.ComponentModel; using System.Text; using System.Data; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; [ViewStateModeById] public class SortablePagedRepeater : Repeater, INamingContainer { private SuperRepeaterPagerBar topBar = new SuperRepeaterPagerBar(); private SuperRepeaterPagerBar btmBar = new SuperRepeaterPagerBar(); protected override void OnInit(EventArgs e) { Page.RegisterRequiresControlState(this); InitializeControls(); base.OnInit(e); EnsureChildControls(); } protected void InitializeControls() { topBar.ID = this.ID + "__topPagerBar"; topBar.NumberOfPages = this._currentProperties.numOfPages; topBar.CurrentPage = this.CurrentPageNumber; topBar.PageChanged += new SuperRepeaterPagerBar.PageChangedEventHandler(PageChanged); btmBar.ID = this.ID + "__btmPagerBar"; btmBar.NumberOfPages = this._currentProperties.numOfPages; btmBar.CurrentPage = this.CurrentPageNumber; btmBar.PageChanged += new SuperRepeaterPagerBar.PageChangedEventHandler(PageChanged); } protected override void CreateChildControls() { EnsureDataBound(); this.Controls.Add(topBar); this.Controls.Add(btmBar); //base.CreateChildControls(); } private void PageChanged(object sender, int newPage) { this.CurrentPageNumber = newPage; } public override void DataBind() { //pageDataSource(); //DataBind removes all controls from control collection... base.DataBind(); Controls.Add(topBar); Controls.Add(btmBar); } private void pageDataSource() { //Create paged data source PagedDataSource pds = new PagedDataSource(); pds.PageSize = this.ItemsPerPage; pds.AllowPaging = true; // first get a PagedDataSource going and perform sort if possible... if (base.DataSource is System.Collections.IEnumerable) { pds.DataSource = (System.Collections.IEnumerable)base.DataSource; } else if (base.DataSource is System.Data.DataView) { DataView data = (DataView)DataSource; if (this.SortBy != null && data.Table.Columns.Contains(this.SortBy)) { data.Sort = this.SortBy; } pds.DataSource = data.Table.Rows; } else if (base.DataSource is System.Data.DataTable) { DataTable data = (DataTable)DataSource; if (this.SortBy != null && data.Columns.Contains(this.SortBy)) { data.DefaultView.Sort = this.SortBy; } pds.DataSource = data.DefaultView; } else if (base.DataSource is System.Data.DataSet) { DataSet data = (DataSet)DataSource; if (base.DataMember != null && data.Tables.Contains(base.DataMember)) { if (this.SortBy != null && data.Tables[base.DataMember].Columns.Contains(this.SortBy)) { data.Tables[base.DataMember].DefaultView.Sort = this.SortBy; } pds.DataSource = data.Tables[base.DataMember].DefaultView; } else if (data.Tables.Count > 0) { if (this.SortBy != null && data.Tables[0].Columns.Contains(this.SortBy)) { data.Tables[0].DefaultView.Sort = this.SortBy; } pds.DataSource = data.Tables[0].DefaultView; } else { throw new Exception("DataSet doesn't have any tables."); } } else if (base.DataSource == null) { // don't do anything? } else { throw new Exception("DataSource must be of type System.Collections.IEnumerable.
