Render Charts.js on backend side asp.net
The below is some code I've used in a similar situation, which takes some html and produces an image of it (cropping whitespace). I'm not sure when in the page lifecycle Chart.js draws it's charts however so this may not work. You could adapt it to load an actual page rather than passing in HTML. Not pretty, not platform agnostic, and could have varying results depending on versions of IE etc. (e

Response.Write and postbacks in ASP.NET

Is it possible to do unit-test ASP.net MVC views without precompiling the views?
You can render Razor views standalone using RazorEngine or one of the solutions here. This will give you HTML which you will have to parse. However, the reason you haven't found any examples of testing views is that few people do it. Views are declarative; they don't have logic. It takes time and effort to develop a test strategy for views. A better strategy might be to move any logic contained

Is it possible to use jquery ui controls instead of web controls in asp .net web forms?
You can use any controls you want. However, non asp.net controls will not postback to your server. You will need to manually call the __doPostBack(); asp.net method using javascript. Also, since none of you controls will be wired to do postbacks using the built in asp.net mechanism, you will need to force your page to generate that code for you by calling something like this: var cs = Page.Client

Accented characters of a vCard not displaying in Windows Contacts
Just because you add a "CHARSET=utf-8" parameter doesn't mean the value will be written in UTF-8. You are probably not setting the character encoding to "UTF-8" when you write the vCard. Also, note that vCard version 4.0 does not support the "CHARSET" parameter. The specification states that all vCards MUST be written in UTF-8.

Pass User info to WCF Web service with WCF method vs with Soap header
I believe it's better to pass some kind of user ID in a header of every message you send to your WCF service. It's pretty easy to do, and it's a good way to get info about user + authorize users on service-side if needed. And you don't need 4000 instances of webservice client for this. You just need to create Behavior with Client Message Inspector on client side(and register it in your config).

In the test/Default.aspx example, you are creating a web request that is originating on the server, hence the "runat='server'" parameter. If you are trying to create an ajax request that originates from the client, you will need to use a client side script like javascript. You could use jQuery to do this by doing something like: $.ajax({ url: "/?eval=zGetClientInfo" }).done(function(data) {

You are doing the validation wrong. First of all ValidationGroup is used to group validations so in a button click you validate the fields in that group.

Checking the value in this property will not indicate that your values in your controls are valid or not. So t

Difference between AJAX Helper and async/await
They are actually completely different. The key to understanding the difference is to think about the HTTP protocol. In the HTTP protocol, you have one request and one response. That's it. The client makes a request, and the server creates and sends a response. When you use async and await in a request handler (such as an MVC action), you still only have one response. async doesn't change the HT
