Changing Display="None" to Display="Dynamic" in the asp:CustomValidator causes the asterisk to appear. Changing ShowSummary="false" to ShowSummary="true" in the asp:ValidationSummary causes the error message to appear in the summary. share|improve this answer answered Dec 19 '12 at 20:14 Carson63000 3,26311534 I realized

This is not inside an update panel or anything. I'll try to post the all the related code. <%@ Control Language="C#" AutoEventWireup="true" CodeFile="AccessorialManager.ascx.cs" Inherits="Controls_AccessorialManager" EnableViewState="true" %>
Accessorial Setup - Dry Run Max Charge: https://blogs.msdn.microsoft.com/rickandy/2008/12/31/custom-validation-error-message-not-displayed/ Products table from the NorthWind Db to reproduce the problem and show a work-around. Create a partial class for the Products entity: [MetadataType(typeof(ProductsMD))] public partial class Products { public class http://www.c-sharpcorner.com/uploadfile/manas1/displaying-dynamic-error-message-in-asp-net-custom-validator/ ProductsMD { [DataType("dummy", ErrorMessage = "El campo debe ser un entero positivo")] [DisplayName("En la acción")] public object UnitsInStock { get; set; } } }VB _ Public Class Products Public Class custom validator ProductsMD _ Public Property UnitsInStock() As Object End Property End Class End Class

Navigate to the Products table, edit a row, and change the UnitsInStock to a letter. Select update and you will get a default error message, not the message applied with the DataType attribute. The example above validator error message was doomed to failure as the DataType attribute above does not match the DataType enum or have a matching field template. There are a couple of possible solutions for displaying custom validation errors on integer conversion failure. You can add the compare validator message that will be displayed for any validation error. The code should be added as the last statement of the Page_Load method in the DynamicData\FieldTemplates\Integer_Edit.ascx.cs (or .vb) file. CompareValidator1.ErrorMessage = String.Format("El campo {0} debe ser un entero", Column.DisplayName); or for VB CompareValidator1.ErrorMessage = String.Format("El campo {0} debe ser un entero", Column.DisplayName) Entering a non-integer such as Z to the units in stock field now yields the following error message: El campo En la acción debe ser un entero Adding the CompareValidator1.ErrorMessage to the integer template works for every scaffolded integer. For more flexibility, you can extract the custom message from the data model partial class. Replace the CompareValidator1.ErrorMessage line above with the following in the Page_Load method. var dataTypeAttribute = MetadataAttributes.OfType().SingleOrDefault();

if (dataTypeAttribute != null) { CompareValidator1.ErrorMessage = dataTypeAttribute.FormatErrorMessage(Column.DisplayName); }

VBDim dataTypeAttribute = MetadataAttributes.OfType(Of DataTypeAttribute)().SingleOrDefault()

If dataTypeAttribute I
