I'm currently stuck with a problem with MVC2 RC and validation on a dropdownlist :
I have a page with some fields and a dropdownlist. The dropdownlist is not a mandatory field so I would like to save a null value into my property.
Unfortunately, I can't validate my page with a null selected value, because when I look into the modelstate just on the first line of my action, I've already an error telling me I must choose an item.
Is it normal working of dropdownlist validation or is it a bug ?
i am using a search box for my application which returns a dataset. however when i click on the search button it returns an empty table result. how could i add validation so it doesnt accept empty strings or numbers.
I'm pretty new to ASP.NET MVC and I'm trying to get my head around how validation of dropdown lists work. I have the following property in my ProfileViewModel class:
[DisplayName("Gender")] public bool? Gender { get; set; }
null is meant to mean "unknown", true female and false male. In the view model constructor I
AllGenders = new List<SelectListItem>(2) { new SelectListItem {Text = "Unknown", Value = "null"}, new SelectListItem {Text = "Male", Value = "false"}, new SelectListItem {Text = "Female", Value = "true"} };
First of all, it seems that I have to use strings when populating a List<SelectListItem>, which feels kinda weird. Is this really how it's done?
Secondly, when I choose "Unknown" in the list the validation fails telling me:
The value 'null' is not valid for Gender.
Why is that? When I remove the "null" option and change Gender to a simple bool, everything seems fine.
I'm trying to write a query that will work in two situations. In some situations the value for AOL will be Null and in others there will be a vnumeric value. How do I get this procedure to accept Null if its passed in but also accept a numeric value if it's passed in?
I have a javascript to validate and avoid null values for my form but there are some textboxes that I need to be 'optional'. I tried erasing the validation for province address and province contact in javascript to make it optional, but the problem is whenever I add the values in the database, an error message appears "Input string was not in a correct format". It's in C# This is my present code wherein the provincial address and provincial contact must only be optional:
Iīm creating a user page to enable editing their profiles. When hitting the "update" button, it turns out that the field still contains the old value, although youīre looking at the new one, ie the text property of the textbox isnīt the value of the parameter which in fact gets its value from the text property.As far as I know I havenīt done anything I havenīt done before, both in apps and website?
I'm using MVC 3 RTM, client side validation has been disabled.I have a simple model with one integer field.Server side validation does not accept numbers including one or more thousandseparators.
It shows: "The value '1,000' is not valid for QuantityInStock".It does not matter what culture I use. Both "1.000" and "1,000" are never accepted.
I have A textbox inside formview, ive add litered textbox from ajax and allow only numbers and "."Works fine. THe only problem they can enter multiple dots. I want textbox to accept only following formats: 100, 1234.56 - i.e integers and decimals.
I need to validate integer within a specified range for English and French culture. The integer contains group separator ("," in English culture or " " in French culture). It seems I can't do it with RangeValidator on my machine.
I just want to make sure the RangeValidator can't do this kind validation for Integer before I'm going to write my own control.
I just feel curious because RangeValidator can actually do this kind of validation for Currency!
I am working on a website. I am using C# 2008. I want to make a text box that accept only numbers & comma(,). for example-919981424199,78848817711,47171111747 or there may be a single number like 919981424199.
I was able to do one thing My text box only containing number by using this Regular Expression validation.in its property->Validation Expression i wrote "[0-9]+". This is working but now my requirement is to send bulk SMS & each number is separated by (,).
I have an invoice form where user enters items and amount. I am calculating the amount as the user enters amount in the textfield. I receive an error (Input String was not in correct format) if user enters amount with comma separated values. If there are no commas, my calculation goes through fine.
I have the below stored procedure witch has an error I cann't figure out.
What I want: Gets rankOrder. If rankOrder doesn't have a value (= null) the @num should be insertet as 1 as value. If there is a row and a rankOrder is should set the @num to insert the value + 1. The last one works perfect. But when the row I select is emty = null value the value is set to null in the insert command.
I'm trying to make filters on gridview. Gridview is bound to SqlDataSourceControl.
The problem is when there is NULL value in DB.
Parameters
Code:
[code]....
Select Statement
Code:
SELECT Name, Phone, email FROM suragch WHERE (firstname LIKE @firstname + '%') AND (phone LIKE @phone + '%') AND (email LIKE @email + '%')
Above example works fine if there is no NULL.
When users want to find email they leave phone field empty and enters the firstname. But my example doesn't displaying email of given user if phone is NULL in db.
I've created a WCF Service that Performs Insert User, What it does is, it'l get user name, age,gender,address,phone no and inserts these values into SQL database.
Problem is :
These things are working fine, if i give all the values in the WCF Test Client, It's Not working when i din't enter value for Address and click "Invoke" Button, It's throwing an Exception Procedure or Function "Insert_User" Expects
ADDRESS' Which was not supplied. I've created the SQL table Which allow Null Values for Address.
I've did the same Operaion in WebService also, there it's working fine, if i din't enter any value for tha Allow Null Colums, it's accepting the Null value and inserting into Database.
Why this Problem comes in WCF Test client, Guide me to Get rid of this Problem.
I have an sproc which selects data out of my table. The column can return integer or NULLs.
I get the 'failed to enable constraints error' when databinding. If I go to my tableadapter and select my column there is a NullValue property which has 'Throw Exception, Null, Empty'. If I try and unset the exception option it tells me only strings are allowed this. However the 'AllowDBNull' option is set to TRUE.
What is the alternative and will this be fixed in 2010?
In reference to this question that I just asked, [URL] it appears that for some reason, an empty text box's value is not being fed to SQL Server as NULL, as it ought to be.

I'm currently developping an application using MVC2 and Globalization (fr and de). I'm creating a form who use DataAnnotation on the model for validation, with localized error messages in my dataAnnotations.
Here is the trick :
I have two <input /> :
One for a required date (example : 12/05/2001) wich is a DateTime field in the model :
[Code]....
One for an optionnal hour (example : 22:30) wich is a DateTime? :
[Code]....
Erreur and LibellesSinistre are my ressources files.
I got two problems :
I can enter a date in my hour field and an hour in my date field.My error messages aren't localized. Do I need a trick or something to make it work ?

I've written a custom ASP.net control that descends from LinkButton and overrides the Render() method. I'm using it to replace ImageButtons in the site I'm working on so we don't have to have an image for each button. This control works fine, does the required post-backs etc., however it doesn't fire the validators in its validation group. This is obviously an issue. The code for the control is (condensed) as follows:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls;
Does anyone know why this would not be causing the validators to fire? I was under the impression that leaving all the other methods in LinkButton un-overridden would leave all the other functionality the same.
