Server-side validation on an Entity Framework required field (property) does not work!

Posted By:      Posted Date: August 29, 2010    Points: 0   Category :ASP.Net
Has anyone had issues getting server-side validation on an Entity Framework required field (property) to work? The data type is a string (nvarchar). Server-side validation for required fields of other data types WORK fine. Only string fields have issues. I get the following error on UpdateModel(obj); of my POST method within the controller. Exception Details: System.Data.ConstraintException: This property cannot be set to a  null value.Source Error: Line 4500:                OnTextChanging(value);Line 4501:                ReportPropertyChanging("Text");Line 4502:                _Text = StructuralObject.SetValidValue(value, false);Line 4503:                ReportPropertyChanged("Text");Line 4504:                OnTextChanged(); I've even tried data annotations like this but it seems to get ignored.     [MetadataType(typeof(ObjMD))]     public partial class Obj     {

How to use server side validation to ensure image field is not null


I'm having trouble accomplishing the above. Below is all the mark up and code. I'm not getting error messages, but the validate image function is not working (fileupload portion is working ok).

In my attempt below---not sure if it's the simplest or best validation approach anyway---the "UserId" parameter appears during rendering to be empty---but in most methods I have it successfully containing or referring to the logged-in user's identification.

Following is the control that refers to the image field (page = advertisement.aspx):

<asp:Image ID="Image" runat="server" ImageUrl ='<%#Eval("UserId","Image.aspx?UserId={0}") %>'


Following is the successful code behind for the page image.aspx referred to above (page = image.aspx.vb):

Partial Public Class Image

    Inherits System.Web.UI.Page

    Public Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Request.QueryString("UserId") IsNot Nothing Then

disable required field validator at server side


Hi everyone,

my question is very simple. I had read through many post include this: http://blog.anasghanem.com/post/How-to-get-the-readonly-textbox-value-on-the-server-.aspx

I have a calender extender and the date was target to a texbox. This textbox, i had set it to readonly and it is validate by a required field validator. so mean this texbox must have a value inside. my prob is, i bind the textbox to database and if data is NULL or empty i can't save it because the required field validator was validate textbox as empty value at cllient side. If i remove the required field validator everthing fine. But this is not i want. I have try to set the textbox to javascript onCopy,onPaste,onkeyup. but user also can delete and paste into the textbox.

i have think to disable the requried field validtor at server side when data is inserted. Anyone know how?

VS 2010: no Entity Framework or LINQ support for SQL Server 2000 SQLOLEDB connection?

Hello, I'm working with Visual Studio 2010 and for Data Connections am connecting to a SQL Server 2000 production database. When I try to drag a table to a .dbml file, the Object Relational Designer says, "The selected object(s) use an unsupported data provider."If I try to create an .edmx file via Generate from database, then the alert is, "This server version is not supported. You must have Microsoft SQL Server 2005 or later."So VS 2010 has no support for the Data Entity Framework or LINQ when connecting to a SQL Server 2000 database? If that is the case, what is the best data access strategy for this scenario?  

SQL server 2008 compact editioin + Entity Framework: Can we backup the SQL server compact edition da

Data Annotation not triggering the client side validation when used on an overriden model property

Hi all, This is a saga from a post that was recently answered:http://forums.asp.net/t/1598187.aspxMy main problem is the lack of client side validation when we use a child model class, the server side validation works like a charm whether you use the virtual/override solution or the new attribute on the child class with the getter and setter linking the property to the base class's one.The client side validation does not work with none of the solutions presented below.This is a sample code of the first solution: [Serializable] public class DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] public virtual int? Year { get; set; } ... } [Serializable] public class BirthDateViewModel : DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] [YearRange(ErrorMessageResourceType = typeof(App_GlobalResources.Messages), ErrorMessageResourceName = "Validation_Range")] public override int? Year { get; set; } ... } This is a code sample of the second solution : [Serializable] public class DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] public int? Year { get; set; } ... } [Serializable] public class BirthDateViewModel : DateViewMod

Modal Popup Extender server side Show() does not work


Hello. Im using a modal popup extender to tell my user that the page has successfully been updated and then redirect them to a new page with the ok button. The thing is that i do NOT want this extender to fire when i press the button. I would rather call the Show() function myself. Right now i have a simple test page with a button that calls the popup extender Show() function but Nothing happens. If i set the targetID to the button it works but Im not able to call it through codebehind.

Any thoughts?

Server Side Validation for SharePoint 2007 Form Fields


Hi Guys,

Need to validate NewForm.aspx and EditForm.aspx of SharePoint custom list. My current implementation is by using JavaScript. It's working fine.

Someone suggested JavaScript is not a good approach.I am unable to fetch ids dynamically by JavaScript only for few fields (people picker, calendar control) and in that case i have hard coded the ids. hardcoding is always a bad approache.

Is there any way to validate those mentioned form at server side? Is it really good way to think that my validation can put inside Event Handler?

thanksArup MCTS - SharePoint

Field validation failure on not required/blank drop-down box


I have a column in my list that is based on the records in another SharePoint list. When I try to edit a record in Datasheet View, I frequently get the following validation rule failure message:

The text entered for Client Impacted isn't an item from the list. Select an item from the list, or enter text that matches one of the listed items.

Even though the column appears to be blank to the naked eye, when you double click in the column, it selects what appears to be a space character and when you hit the delete key, it now passes the validation rule. So, my assumption is that the validation rule is saying something like "Space character isn't in the list, so you can't save the record..." Here's what's odd. I do NOT get the same validation rule warning when I edit in standard view and I know for sure that the column has not been erroneously filled with a space character. Anyone have any idea what might be going on here?

Thanks in advance for your help.


Do Ajax Toolkit Extenders participate in server side validation?


If I use the extenders (for example mask edit) in place of some of the built in validators such as RegularExpressionValidator for exampe, will Page.Validate() still be called automatically and perform server side validation using the extenders?

Server Side Validation


Hiiii Coders,

I have a listbox which has a list of customers,now i want that user must select a customer from listbox before hitting a save button. Also i have a new button for new customer. Means in case of new customer user will click on new button and a textbox will become visible just below the listbox. So in case of new customer user must enter a new customer name in textbox before clicking on save button.

It is something like requiredfieldvalidation

Also i want validation on server side

plz rep asap

thanx and regards
