C# - Get Variables From JavaScript To (MVC)
Mar 6, 2010
I'm using ASP.NET MVC (I'm really new to both asp.net and the asp.net mvc type projects, but trying hard to learn).
I've set up MVC with a controller so that it runs a C#.net method which;
queries an mssql db
converts it to json
returns the json string
It's called from the javascript by requesting an url with a parameter. But what I need now is for the C# part to read two integer variables from the javascript. What would be the best way to do that, and does anyone have any good examples/code that I could look at?

I have this code in javascript: var x = e.mapX; It gets the X-coordinate of a map. What I want to do is that I want to store this into a c# variable. I have a class named Test with an integer property X. I want to store var x into X. In the codebehind, I have this on the Page_Load: Test test = new Test(); Then I am trying this on the javascript code: var x = e.mapX;

I have a webpage in which I declared a variable in my code-behind as:
Code : Private ok As New HiddenField
I have a javascript function that sets this variable to either "T" or "F". However, I have a server-side button control that in the click() event, it checks the "ok" variable like this:
Code:
If ok.Value = "T" Then
FormatFields()
End If
The javascript function initializes the "ok" variable to "T". It goes thru a series of field edits. When a field doesn't pass the edit, it sets the "ok" variable to "F". Either way, this variable has a value. When the code-behind event above checks the "ok" variable, it's value is "".

var elem = document.getElemntId('<%=control1.ClientID %>');
var elem2 = document.getElemntId('<%=control2.ClientID %>');
var elem3 = document.getElemntId('<%=control3.ClientID %>');
Can I do it in some form of concenation like:

Is there a way to assign/pass/copy a javascript variable to a server side variable in C#? For the sake of argument, let's say that I was able to parse some JSON for variables that I want to store and assign them on the client (ie. var = FirstName and var = 25 and var = someDateTime, etc) .

I have a nested ListView (Master/Detail) and want to invoke a JavaScript function in the detail ItemTemplate so that this function can call a static method on the server site and post the field update. I need to include three data variables in the function call, two of which must come from the ListItem data. The JavaScript call to SaveAnswer that is contained in a list item embedded in the inner listview does not render properly. The code must pass three variables: ThisPAQID is a public variable from the codebehind. I could probably make it a hidden variable on this page. QuestionID is a variable from the current listitem and is contained in the table cell immediately preceeding the SaveAnswer method call.
The nested listview works great, and if I dummy the PAQID and QuestionID values in the function call (e.g. SaveAnswer(1,1, this.Value), it works fine.
<asp:ListView ID="lstQuestions" runat="server" OnItemDataBound="lstQuestions_ItemDataBound">
<LayoutTemplate>
<table>[code]....
When I put a breakpoint into this code in FireFox, the break never fires. Do I need an "OnBlur" tied to this code? Clearly I am not a JavaScript wizard.

I am working with Google maps api V3. I need to get the values of the getSouthWest & getNorthEast bounds of my map. To do this the 'bounds_changed' event needs to be fired in order to get the new values. This is all good, however, I need to access these values from outside the event and passed to a server side function (more specifically, I don't want to call my server side function every time the map bounds are changed).
My code is:
//Global
var sw, nw, Searchbounds;
function myFunc(){
google.maps.event.addListener(map, 'bounds_changed', function() {
Searchbounds = map.getBounds();
sw = Searchbounds.getSouthWest();
ne = Searchbounds.getNorthEast();
});
CallServerSideWebService(sw.lat(), ne.lng(), ne.lat(), ne.lng());
}
When executing this code I get the error message sw is undefined.

For some reason it seems as though variables that I declare in javascript sometimes persist themselves across applications even when I do a response.redirect. I thought that a response.redirect would clear them out.

From what I understand, the id of the master on an ASP.NET page is "aspnetForm". I noticed today that for some reason in one of our pages it's now "form1". What would cause this change? Where should I look for the root cause of this naming change? We've got a lot of JavaScript variables that (sign) reference "aspnetForm" that are now broken.

whats the exact use of static variables in overall programming in .net and for asp.net...
Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.

I cant figure out how to use the Application["myvar"] variable to store data for the application in asp.net 4.0 web app using c#. It say Application is not a known object and I can't for the life of me figure what to do a "using" on to expose it. I am in a static class at the time I cant use it. It seems to work in other units?

I have this function that I want to pass the IP and port to and check for a connection. It works fine if I put "127.0.0.1" in the tcpClnt.Connect line. But if I pass the IP2 as shown in the line commented out, it tells me No such host is found. It's like it thinks "IP2" is the host name. How can I pass a variable in there?

I know what they are and how they are used but i am not sure about their feasibility. Their use is always advised to be avoided. can some one explain me when they should be used and when not?
Aif i have a choice between static veriable and session for just storing an integer which one of these should i prefer??

I have some WCF services. These services run in ASP.NET. I want these services to be able to access a static variable. My problem is, I'm not sure where the appropriate server level storage mechanism is. I don't want to use the database because of speed. But, I want the static variables to stay in memory as long as possible. In fact, I'd like it to stay until I restart my server if it all possible.

I'm having some troubles using Session Variables as they are being used as Reference and I want to use them as value.
I got to this debuging my solution and I created something like:
DataTable dt =
(DataTable)HttpContext.Current.Session[
"SearchReturn-DataTableSchema"];
// Adding Rows of Data to DataTable dt
HttpContext.Current.Session["SearchReturn-DataTable"] = dt;

why I couldn't get the variable from the URL.
<meta property="og:title" content="<% Response.Write(Request.QueryString["title"]); %>"/>
For some reason the code, <% Response.Write(Request.QueryString["title"]); %>, does not retrieve the data in this case. It works fine if I put it in the title tag though.

This question actually refers to a classic ASP page I'm working on, but I'm assuming that app variables work the same in both ASP and ASP.NET Let's say we have a bunch of websites, owned by different people. The sites are all different, but the common theme is they are car enthusiast websites. Each of these websites has their own unique index page (of course), but also "common" pages, which are pages shared by all the websites.
One of the common pages, checks for the value of an application variable, which may or may not exist. For example, lets call this page luxurycars.asp, which is a simple page that shows the top 10 luxury cars of this year. This common luxury car page will pull and use the app variable like so:
[CODE]
Dim SiteOwner
SiteOwner = Application("OwnerName")
Response.Write("This site is managed by " & SiteOwner)
[/CODE]
This app variable is set uniquely in each clients index.asp page like so:
[CODE]
Application("OwnerName") = "John Doe"
[/CODE]
Will this work? I just started learning classic ASP (for my job), and I'm reading that application variables are universal and only one copy of the variable will exist. So does this mean if John Doe sets Application("OwnerName") to "John Doe" in HIS index.asp page, will everyone that visits the common luxury car page see John Doe's name? Regardless of whether they got to that page via John Doe's page or someone elses? And if so would using a Session variable instead solve this problem? Sorry if this sounds confusing, let me know if I need to re-word it or give more detail...

This is my first time working on a secure website. It's for a pet project I have.
For security purposes, where is it best to store information like SQL connection strings, database encryption keys, etc? Is it better to use web.config, store them in a class that accesses a database (like dataBaseHelper.cs or something), or somewhere else?
I intend to obtain an SSL cert as well. When communicating with the database, should I always use the secure connection?
