In my application, the client must sign (using a certificate) and send data to the server.My doubt is how should I do it?
To sign on the client side, I should use ActiveX right? My problem is that firefox doesn't support it.
Signing on the server side I have two options:
Save the private key on the server and use it when necessary (if the data is modified during the transaction it will sign false data)Send the private key when necessary (may comprise the key)
Despite using SSL, I'm not very confortable with any of the two options for signing on the server side...
I have to implement the print functionality on aspx page like on click of print image icon user will be able to get the print out of aspx page .aspx page will contain the server controls like textboxes , Gridview etc which one approach will be the best server side or client side printing ?
I have two applications one already installed at client side, and a web application hosted on some server, in web application there is a page from which there is an option to run that application,how can I do this.
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript"> function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
[code]... Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?
I Getting A Problem In DataGrid's ItemDataBound Event. I Am Calling A JavaScript Function In DataGrid's ItemDataBound Which Retrun The CellIndex And RowIndex Number On Which UserClick After That I Am Re-Binding The DataGrid With jQuery Function After That ItemDataBound Event Not Working. I Want To Call The Same Function Again. Is Their Any Method To Call A Server-Side Function On ItemDataBound Event Except Client-Side Function..
I have an application that exposes a number of ASP.NET web services at an internet location. For security reasons, I want to be able to authenticate clients, and reject any that are not authorised. The authorised clients in question will be ASP.NET web applications, but I do not have guaranteed access to their IIS configuration, nor to their local certificate stores, therefore the solution must not involve any of these items.
However, authorised clients, will always make calls to the web services using wrapper methods provided by an assembly that I do have control over. My idea is to digitally sign that assembly, and use that signature as the basis for authenticating the client.For that to work, the assembly will need to be able to construct an X509Certificate object from itself, and to attach it to the call to the web service:
Then the web service must be able to compare the incoming request certificate to its own signing certificate to authenticate the client:
X509Certificate requestCert = new X509Certificate(Context.Request.ClientCertificate.Certificate); X509Certificate signingCert = X509Certificate.CreateFromSignedFile(Assembly.GetExecutingAssembly().Location);[code]...
The documentation for the method doesn't help much, other than remarking that ASN.1 DER is the only certificate format supported by the method. if I am signing the assembly incorrectly, misunderstanding the method itself etc.? Or more generally if the approach I am taking will work or is flawed?
We currently have the code in WCF to sign the outgoing client requests' SOAP Body, however we need the same code for use with WSE 3.0. I can't find any examples of this.
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?
I m using site login Control in my login.ascx file and disaplaying login control in Div so if there is login link in page and i click on that then Login Div will popup which is site login.May i know how can handle error like username or password is incorrect on client side instead server side?
i can use escape() and unescape() functions by Client side easily, but the problem when i have use escape() method for peice of HTML , then i dont know how to unescape this piece of HTMl By Server Side not By Client Side. how i can unescape (escapped HTML) by server side?
I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.
I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)? Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
If I have a standard HTML textbox: I can retrieve the value using Request.Form. But how do I go about populating this textbox from the server-side? I tried Request.Form["txtTest"] = "blah"; but got a readonly error.
The idea is that a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button). These rows contain textboxes, dropdownlists, checkboxes and other input controls. When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on server side, validate it and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows. put me in the right direction?? Or someone offering a better solution to the problem?
I have a content-sensitive firewall between my clients and my server. If we exclude SSL solution (it's not available in my case) then I was thinking of a javascript library which encrypts custom fields at client-side and a .NET class decrypts them at server-side. Is there any solution out of the box (maybe a server control) ?
