Validation Support

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :WPF
I have a page that shows customer information. I have a Customer class in my business layer project that I want to contain the validation logic. I'm struggling with the best way to achieve this using the built in mechanisms that WPF provies (assuming that's the best route to go). I've seen examples where people throw exceptions from the individual field getters/setters of their business classes. I can't do that because this class is generatd by LINQ to SQL so all the fields getters/setters are already defined in the auto generated partial class. I decided I would just create a Validate() method on the Customer class that returns a list of errors and call that when the user clicks the Save button. I could just put some kind of logic in the UI to show a panel with a listing of errors or set some tooltips on the form fields, but I was wondering if WPF had some built in support for this type of validation.

ASP.NET, HTML, JavaScript Snippet Support (VS 2010 and .NET 4.0 Series)

This post covers another useful improvement in VS 2010 - HTML/ASP.NET/JavaScript snippet support. Snippets allow you to be more productive within source view by allowing you to create chunks of code and markup that you can quickly apply and use in your application with a minimum of character typing.

Visual Studio has supported the concept of "snippets" for VB and C# in previous releases - but not for HTML, ASP.NET markup and JavaScript. With VS 2010 we now support snippets for these content types as well.

Multiple database support with Entity Framework

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

.NET 3.5 Adds Named Pipes Support

you want a named pipe server, all you have to do is create some instances of NamedPipeServerStream to handle each client connection. I stole the following code straight from the MSDN documentation.

Server side validation of Fileupload control not working

Can anyone help me please?


I have been producing a registration form using html and asp.  I have managed to get it to send an email having copied script from a previous website which someone developed for me.  I now get the response going to the old address and with then old text.  How can I change it all to the new site?

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

VS 2010 HTML validation "in CSS" option - where the hell is it?


In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.

1. am I blind?

2. they decided it is too convenient to use and removed it?

3. they will "introduce" it in SP1?

What is going on? That one thing made me move back to VS 2008 web developer.


PHP support for VS 2010


While I do most of our development in .net, we do have some systems in php. I was just wondering if there is any php support for VS 2010. I found vs.php 2.7, but frankly, VS is expensive enough, I don't want to have to buy something else for php support. I use eclipse right now which works fine, I just kind of wanted to consolidate my editors and only have one. Does anyone have any ideas for me? Thanks,

deploying to msdeploy does not support a proxy server


I am trying to deploy through webmatrix but my system Proxy server configuration is not being used. I assume that webmatrix would detect the proxy server settings and use that for the msdeploy calls under the hood. Can anyone confirm this is a know issue?

set messageTemplateResourceName from resource file in Validation appication block.



  I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.

Here is my code:

<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250"
              upperBoundType="Inclusive" negated="false" messageTemplate=""

              tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris
