2. How to code professional way? I mean how to separate code using different classes and how to link all togerther?

MVC :: Get Validation Message If Click Submit Without Entering Anything In The Input Field?

Mar 12, 2011

I'm a total newbie with MVC -- learning it with MVC3 using Razor.

I just watched the video on PluralSight and was just following along with the example. I created my own Movie and MovieRepository objects. I then created a strongly typed view for adding a new movie. This is what's in the view:

[Code]....

My Movie object looks like this:

[Code]....

If I click submit without entering anything in the input field, I get validation messages i.e. The Rating field is required or if I enter non-numeric data, I get The field Rating must be a number.

I didn't wire this and wanted to understand where this is coming from.

Using Webform User Control On Webform In MVC Project?

Feb 26, 2010

I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:

The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).

I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event

I am using this signature control. Here's the web.forms code...

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="KahunaCentralTIDRevamp.SignatureCapture.Index" %> [code]....

Security :: Allowing User To Input HTML Code Securely?

Jan 30, 2011

I have a CMS page that allows the user to paste in or type HTML code into a TextBox in a FormView, then do an INSERT or UPDATE operation to an nvarchar(MAX) column in an SQL table. This is using an ObjectDataSource that refers to an insert or update method in a TableAdapter in my dataset.

When testing, the server initially warned me when I tried to input or update text containing HTML code; so I set the validateRequest="false" in my page header.

I gather this can be a serious security risk. What's the proper way to "validate" the string being input? Am I opening the database to SQL injection?

Only the site administrator has access to the CMS, but malicious could theoretically bust their way in...

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?

Fuga.

VB.NET Web Application Input Box / Input Box That Comes Up When A User Clicks 'Find' Button?

Aug 4, 2010

I would like to program an Input Box that comes up when a user clicks 'Find' button. It asks 'Please enter an employee number'. Then it takes the employee number typed into a text box and searches a dataset for that specific employee record.

I know that it should be server side because the client may not have the proper javascript installed or diabled. Therefore, can someone give me some code to put in code behind that can pop up an input box and use the input after, if this can be done?

Is It Possible For A User To Recover Their Password By Entering Their E-mail Address Alone

Jan 19, 2010

Is it possible for a user to recover their password by entering their e-mail address alone?

Right now I am using the PasswordRecovery control, and i have security questions disabled. So all the user has to do is put their User Name, and hit submit, then their password is e-mailed to them.

But, a lot of my users forget their User Name, so right below I have a User Name recover section. The user inputs their e-mail address, and their corresponding user name shows up.

I would like to simplify this and just require the user's e-mail address to provide them their user name AND password.

I am struggling to login into my web portal on my new sony vaio laptop. I think that I need to do some settings, or download some plugin. Infact I don't know what to do, as I have spent many hours trying to login, but no success. Below is my office website:[URL]When I enter my credentials and click login, the web page gets refreshed, i.e username and password get erased, rather than taking me into my web-portal. The laptop is having windows 7 home premium, with ie8. I have also tried installing firefox, chrome, opera and safari, but same problem.

as sony has refused to take the laptop back and they are saying that there is problem with website. Similarly, website staff are saying that there is a problem with the laptop and not with the website.
