How To Validate In MVC
Sep 6, 2010
Iam using Integrating Validation and Business Rule Logic with Model Classes. But the valdidation happens only when I save to database, I have a Createpage, and a previewPage.. so Daving happens in Previewpage. So I want the validations to happen in the first page, where the filling happens. How can I make this work?
What kind of validation should I use? I read recently about dataAnnotation.. I wounder if it's good Idea?
I want also to make some length validation, and password validations.

I'm trying out the jQuery Validation plugin jQuery Docs Here is the markup of my form:
<% using (Html.BeginForm("action", "contoller", null, FormMethod.Post, new { id = "sxform" })){%>
<div id="manifest">
Manifest Option:<br />
<%= Html.DropDownList("docid", ViewData["manifests"] as SelectList, new { @class = "required" })%>
</div>
<div id="release">
Release Version:<br />
<%= Html.TextBox("release", null, new { @class = "required" })%>
</div>
<div id="locale">
Localization:<br />
<%= Html.DropDownList("localization", ViewData["localizations"] as SelectList, new { @class = "required" })%>
</div>
<div id="label">
Label:<br />
<%= Html.TextBox("label", null, new { @class = "required" })%>
</div>
<div id="session">
Session ID (optional):<br />
<%= Html.TextBox("sessionInput", null, new { @class = "required" })%>
</div>
<div id="submit"><input type="submit" value="Build" /></div>
<% } %>
JS:
$(document).ready(function(){
$("#sxform").validate();
});
I am using MS MVC HTML Helpers to render this form. The resulting markup looks fine. IE each input and selection element contains the attribute 'class' with the value 'required'. When I submit this form the validation does noting.

I have a form that looks like this :
[ enterdata: [______] ; more data: [_____] ; (SUBMITBUTTON) ]
[ Filter: [_______] ; (SUBMITBUTTON) ]
The top half has validators. I want to be able to type into the Filter textbox and press enter to fire it's submit button - but when I press enter, it validates the top half of the form also. I have all the controls in the top half on one ValidationGroup, and all of the controls on the bottom half in another.

I am using a client side validation and it is starting to get messy, considering I am making a form. With all the textbox and radio button validations, the controller will be overwhelmed. How do I validate and display the error Message for Radio Buttons and multiple textboxes in MVC on the MODEL side? A simplified version of what I have.
public class ModelData
{
public string ContactName { get; set; }
public string ContactAddress { get; set; }
public string ContactPhone { get; set; }
public bool RadioPoliceFire { get; set; }
public bool RadioComplaint { get; set; }
//The following is a Failure :(
public string RadioType
{
if (RadioType == null)
{return "Type Required";}
return null;
}
//End Failure
}
CONTROLLER...
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Info(ModelData InfoData)
{
if (infoData.RadioType == null)
{ModelState.AddModelError("RadioType", "Type Required");}
try
{ ...
return RedirectToAction("Confirmation");
catch
{ModelState.AddModelError("RadioComplaint", "Error");}
}

I have this kind of problem, that in one of my page, there is a textbox have a validator that requires inputs. So, if I leave the textbox blank, the page will be invalide to submit. In this case, if I click on loginStatus control to try to login, it will not jump to login page because I did not input anything in the textbox...
I checked the loginStatus control, it will generate html code like this:
<a id="ctl00_Header1_LoginStatus_Master" href="javascript:__doPostBack('ctl00$Header1$LoginStatus_Master$ctl02','')"> login </a>
I think it will do some post back, and because the page is invalid, it can not post back...
So, I would like to know, how to avoid the validator for loginStatus?
