customvalidator

问题 Writing a custom validator for a dropdownlist that is using autopostback. Seems to ignore the validation altogether. Why is it ignored and is there an easy fix? Note I did not use ControlToValidate asp.net: <asp:UpdatePanel ID="updatePanel" runat="server" UpdateMode="Conditional" Visible="true" RenderMode="Inline"> <ContentTemplate> <asp:DropDownList ID="ddlCommandAssign" runat="server" AutoPostBack="true"> </asp:DropDownList> <asp:CustomValidator id="val_command_assigned" runat="server"

问题 I have a DTO class that looks, for example, like this: public class ExampleDto { [DataMember(Name = "Date", IsRequired = true, Order = 1), Required] public DateTime Date { get; set; } [DataMember(Name = "ParentExample", IsRequired = false, Order = 2, EmitDefaultValue = false)] public Guid? ParentExampleId { get; set; } } If, as an example, a user provides an incorrect date, such as this: <?xml version="1.0" encoding="UTF-8" ?> <ExampleDto xmlns="http://customurl/"> <Date>2012-05-25T18:23

问题 I'm trying to implement a .NET Custom Validator that uses $.ajax to query a WebMethod on the same page and return a boolean value to indicate whether the result is true or false. The WebMethod I'm using is really simple [WebMethod()] public static bool IsPromoValid(string code) { string promoCode = "ABCDEFG"; bool result = code.ToLower() == promoCode.ToLower(); return result; } The CustomValidator looks like this <asp:CustomValidator ID="cvPromoCode" Display="None" ControlToValidate=

问题 I would like to be able to use the MVC validation + my custom javascript validation. The MVC validation is really nice for Model Validation. The main problem here, is that I have more complexe validation. Ex: Case with MVC Validation <div class="editorSmall"> <div class="editor-label bold"> <%: Html.LabelFor(model => model.Location.CurID)%>: </div> <div class="editor-field"> <%:Html.DropDownListFor(model => model.Location.CurID, Model.CurrenciesList)%> <%: Html.ValidationMessageFor(model =>

问题 I have a webform with two custom validators: One to validate that a string is a date. I don’t care what format, so long as it’s parseable. Another to ensure that one date is equal to or greater than another. I just couldn’t get the compare validator to play nice with any date format. <asp:TextBox ID="txtResourceStartDate" runat="server" CssClass="textBox mandatory dateField" /> <asp:CustomValidator ID="valResourceStartDateIsDate" runat="server" ControlToValidate="txtResourceStartDate" Display

问题 Hi I am working on a custom form field validator, it seems like the custom validator is working by not allowing it to continue to the next page, but it doesn't update the Validation Summary nor does it display the asterisk and the labels that i've made visable. I also have other validators like RequiredFieldValidator on the same field. My ValidationGroup is set, as is the Text and IsValid. I even wrote and set a dummy client side validation method in javascript as some workarounds suggests.

问题 I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one) <asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" /> <asp:TextBox ID="FromDate" runat="server" Columns="8"></asp:TextBox> <asp:TextBox ID="ToDate" runat="server" Columns="8"></asp:TextBox> <asp:CustomValidator ID="DateValidator" runat=

问题 Scenario: I've added a client side url validator using the following regex pattern. The pattern is supposed to check whether the URL input matches. ^(?#Protocol)(?:(?:ht|f)tp(?:s?)\:\/\/|~\/|\/)?(?#Username:Password)(?:\w+:\w+@)?(?#Subdomains)(?:(?:[-\w]+\.)+(?#TopLevel Domains)(?:com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|museum|travel|[a-z]{2}))(?#Port)(?::[\d]{1,5})?(?#Directories)(?:(?:(?:\/(?:[-\w~!$+|.,=]|%[a-f\d]{2})+)+|\/)+|\?|#)?(?#Query)(?:(?:\?(?:[-\w~!$+|.,*:]|%[a-f\d{2}])+=
