I have the following C# method, how can I call it from an HTML a tag?
CLICK
public void MyFunction()
{
Response.Write("<script>alert('Hello');</script>");
}

You can use jQuery ajax to MVC action:
function CallMyCShartAtion(id)
{
$.ajax({
url: 'urlToController', //path to the contoller's action
data: { id: id }
}).done(function() {
alert('Added');
});
}
And then
CLICK
http://api.jquery.com/jQuery.ajax/

This isn't directly possible (at least not in the way you're trying to do it). First of all, JavaScript is typically a client-side language, which can be run in your browser, as opposed to C# (or Java or PHP or...) which is typically run on the server side.
In order to accomplish this task like you're asking for here you need to
have some kind of backend in place (say, in C#)
issue a request from the client side (frontend) to the backend (e.g. using AJAX)

Use direct javascript for that functionality, no need to use c#

Now that every thing is being converted from the conventional aspx to razor view because of its benefits,
my question is how to achieve thing similar to panel, where in we were allowed that if X is true, show the panel else visible = false.
How can we achieve a similar thing in MVC?

You can do it with razor in the view:
#if(condition) {
<div>............ </div>
}

The panel is actually <div id="yourdivid">...</div> element in MVC view, thus you can either process condition directly on view as Matteo1010 said, or use JS if you want to setup views with only passed values and HTML helpers:
<script type="text/javascript">
var condition = '#[passed condition value here]';
if (condition) {
// show panel
document.getElementById("yourdivid").style.visibility = "visible";
}
else {
// hide panel
document.getElementById("yourdivid").style.visibility = "hidden";
}
</script>
<div id="yourdivid"></div>
I think JS approach with passed value has more advantage to control the view behaviour in client-side than write C# code directly inside the view.

I have a website where a user logs in, can see his information and edit it. There is also another website, something like a site only for admins, where if I click a link it redirects me to the first website, logged in as that user but I can only read his information not edit it. I am having trouble finding out how to make website 1 both readable only and read/writeable.
I am doing this in Asp.NET mvc using C#.

One method would be to check for authorization in the Razor view.
Psuedocode:
#if(User.IsAuthorizedForEdit()
{
#*your edit view code*#
}
else
{
#*your readonly view code*#
}
This does make for some bloaty Razor. The other (arguably, better) alternative is to direct them to the appropriate view in your controller based on user.
Handy-wavy psuedocode to give you an idea:
public ActionResult ViewProfile(int profileId)
{
var user = GetCurrentUser();//without looking at your code, I can't infer this piece.
var profile = GetProfile(profileId);
if(IsAuthorizedToEdit(user, profileId)
{
return View("edit", profile);
}
else
{
return View("view", profile);
}
}
In theory, you already have a read-only view and an edit view, so the latter would be more reusable.

I am coding in c# asp.net using razor technology, I am still getting errors in designing a button that each click considered as vote , and I should display that! But i cant get it in a right logic :(
Here is my code in the view
using (Html.BeginForm("OpenBidPanelOnItem", "Home", FormMethod.Post))
{
<button name="Vote" value="Vote" style="background-color: green; width: 60px">
<b style="color:snow">Vote</b>
</button>
<h3>Total Votes for #registerMember.UserName is : #Model.NumberOfVotes votes</h3>
}
Where should I increment the number of votes by 1.

You will have a OpenBidPanelOnItem action on your HomeController and persist the change to datastore for next render. It would look something like this in C#.
public ActionResult OpenBidPanelOnItem() {
var model = GetModelFromSomewhere();
model.NumberOfVotes++;
SaveModelToPersistentDataStore(model);
}
Your button I assume will need to be your submit button so add type="submit" to the button attributes.
Hope this helps and makes sense.

I am new to asp.net mvc.
now the requirement is that I have to handle following URLs in same ActionResult
if HTTP//jpripu/Handset/shop_code=&hosho_date= then do something.
if HTTP//jpripu/Handset/shop_code=Cust01&hosho_date=20131212 then do something
if HTTP//jpripu/Handset/hosho_date= then do something
if HTTP//jpripu/Handset/shop_code= then do something
Is it feasible to execute above conditions separately?
could anybody help me on this. Thanks.

If you mean URLs like http://jpripu/shop_code=&hosho_date=20130923
then this controller is for you:
public class HandsetController : Controller
{
public ActionResult Index(string shop_code, string hosho_date)
{
ViewBag.shop_code = shop_code;
ViewBag.hosho_date = hosho_date;
return View();
}
}
Note: Index - is default Action, defined in your routing.
Also I suggest Pluralsight Introduction to ASP.NET MVC 3 screencasts as a quick-start quide to ASP.NET MVC.
