MVC :: MVC3 Validations Not Firing?
Mar 21, 2011When the submit button is pressed, the form just posts. No validations occur. What am I missing???
Web Config:

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
I'm running VS 2008 and .NET 3.5 SP1.
I want to implement hit tracking in an HttpModule in my ASP.NET app. Pretty simple, I thought. However, the BeginRequest event of my HttpModule is firing twice for each page hit. The site is very simple right now...no security, just a bit of database work. Should log one row per page hit. Why is this event firing twice?
Moreover, IHttpModule.BeginRequest actually fires a different number of times for the first page hit when running for the first time (from a closed web browser)...3 times when I'm hitting the DB to provide dynamic data for the page, and only 1 time for pages where the DB isn't hit. It fires 2 times for every page hit after the first one, regardless of whether or not I'm touching the DB.
It's interesting to note that Application_BeginRequest (in Global.asax) is always firing only once.

View 13 RepliesI am new to Asp.net MVC. How to give validations for my forms.
View 2 Repliesi cant seem to selectively disable serverside validation using annotations. Data annotations and unobtrusive validation is an awesome feature and has worked out great for us thus far but trying to localize it has been fruitless.
Basicly i have a property in a model object like this (it wraps a DTO)

i can change the output text for things like data range, required, string length etc. but simple stuff like "this field has to be a number" seems hidden away.
I want to implement validations in setter of properties.
how I will do validations before setting value. but not getting what to do if passed value is not correct. Just not setting is not a acceptable solution as I want to return an appropriate message to user (in a label in web form). My example code is:
[code]....
A thought was to use return but it is not allowed.
Throwing error looks not good as generally we avoid thorwing custom errors.
1. Is it always required to use javascript to do client side validation.
2. If we dont want to use the script then can I write the code in c# for validating a control like text box using the events.
3. If I write the code in c#, does it always requires a postback?
how can I implement validations for controls in c#. I am not familiar with javascript, so is it good to write the validations in c#
In web application ,when we follow mvc design pattern ,In which part (M,V or C) does the validations take place??..if we have client side validations using JavaScript thn where they take place?.In .net web applications ,can anyone just clearly mention the differnce between model and controller with some example.
View 2 RepliesIn my form i am having 5 text boxes where onlyone text box will be active(visible=true) and i need validation for it.....Similarly i applied the same validation for all other hidden textboxes which will be activated by another add button click.So here am having only one button to submit the data basing on the user selection of textboxes.So while submitting data in single in textboxes validation is firing in another textboxes also and I dont want it...i want the validation to be fired for the textbox which i activated it.

I want to use Bootstrap validation in child page of a Master Page in asp.net. I need a example of it.
View 1 RepliesBrief overview of my problem......I have certain text boxes(say, txtbox2) in a page that have to be filled only if certain other text boxes(say, txtbox1) are filled. For this, I have disabled the requiredfield validators for txtbox2 in the asp.net code and then wrote a javascript to enable these text boxes on the required conditions. All this works well. In my submit button I have written this,
OnClientClick="if(Page_ClientValidate()) return Check();"
my javascript
Function Check()
{
var Valtxtbox1 = document.getElementById("<%=txtbox1.ClientID%>").value;
var Valtxtbox2 = document.getElementById("<%=txtbox2.ClientID%>").value;
if((Valtxtbox1 != '') && (Valtxtbox2 == ''))
{
alert('Please enter in txtbox2');
ValidatorEnable(document.getElementById('required_txtbox2'), true);

When I am using one of the default validation attributes, like [Requeried], and try to submit the form that is in an invalid state some 'magical' happens and the submit is canceled. I can even click 100x that not a single server request is made.On the other hand, I can't accomplish this behavior when I am using a custom validation attribute. Although my form was in an invalid state, a request is sent to the server anyway.I took a look at the "MicrosoftAjax.js" and "MicrosoftMvcValidation.js" but I am totally noob when it comes to Javascript.How can I accomplish the same behavior for both custom and default validations
View 16 RepliesIn forms I need to do custo validations.

Requirment is to do these on client side.
how this can be done. Secondly can there be some way we just disable a validation group and all validations in this group may be turned to disabl ?
I have a form that uses ASP.NET validations. I am using some inline C# in the aspx to show/hide certain controls depending on a user's role. I would use the Visible property, but there are so many of them, I just decided to do inline C# to show and hide (I know, not best practice, but bear with me for a second). I am having an issue where Page.IsValid is always set to False when I submit my form (when certain fields are being hidden). Will the validations still fire off even if the controls are not even rendered on the pag? Also, if this is not the case, is there an effective way of breaking down Page.IsValid to find out what is setting it to False?
View 2 RepliesWhile develop some asp site i have problem with multiple validations on one field. I have input box and 3 validations for it.
- Required Field
- Compare Validation
- Regular Expression
how to set validations priority. Ex. If Required Field catch error, then Compare Validation and Regular Expression validation messages to be hidden. If Compare validation catch error (and Required field is ok- entered something) then validation message for Regular Expression to be hidden... etc etc...

Is there anyway to throw my error message in the Validation controls as Message box instead of Label?
View 2 RepliesI'm having an accordion panel in my Master page to show all the user menus. To remember the last clicked header menu, I'm doing an async postback in selectedindexchanged event of the accordion panel and storing the new index in session and I'm using thatin my page load to set the selectedindex when user navigates to a new page.If I'm on a content page that has some validators and then click on one of the accordion headers, it's firing the validations on this current page because I'm doing an async postback (by giving the name of the updatepanel in the eventName argument) through javascript using __doPostBack.

I would like to learn to use Validations from a class library in my projects. I am trying to create a simple project, so when a button is pressed a validation from a method in the class library checks to see a textbox on my ASPX form if it has a valid integer in it and a label message display true/false. How abouts would I get this?
