Trying To Make A Client Side Browser Within Webpage
Mar 26, 2011
I am trying to make a client side browser within my webpage so that the user is able to open the file chosen and read the contents in a textbox.
I've read a lot on the internet and all i came across was how to upload a file.

Have some problems with client side validation (using RequiredFieldValidator, RegularExpressionValidator, CustomValidator with client side validation logic). It seems that WebForm_DoPostBackWithOptions is not fired or causes unhandled exception that makes the form to do the postback regardless it's valid or not.
I tried using a ValidationSummary, hiding it if javascript is supported:
<script>
$(document).ready(function() {
$("#javascriptDisabled").hide();
[code]...
Every thing works fine on Chrome with disabled javascript on my laptop, but not on my Android phone. The problem is that on the phone Javascript is not disabled, it's enabled, and correctly hides the ValidationSummary, but does not perform client side validation for some reason that i can't understand (no developers tools on Android browser :(( ).This is very frustrating! :(

In asp.net website, i am using crystal report. My question is very generic i.e. How it is possible to display client side (browser) date and time?
Actually in my case our website is going to hosted at India, while that site is used by user's at SWEDEN.
Now the problem is that when user request for report then it is displaying server side date time because i have used PRINTTIME control of crystal report. But user should have date and time of their PC. because that time is basically a report generates date time.

I am developing a web application that needs to retrieve, display and write data to an SQL database. I'm trying to use AJAX and Javascripts in order to populate fields, lists and data, and to have button and calendar controls on the page that can update the page without refreshing and losing the data page. Therefore, it's necessary that I find ways to doing as much as possible client-side, without page refreshes.
Now, for security purposes, I've heard that there's a method for retrieving a copy of all relevant data from SQL at loading time, keeping a copy of it, perhaps on a separate page, and send-retrieve-display this data on my page, and then, at Submission time, write this data back to the Server. This is to minimize hits to the Server and to preserve data integrity. I've heard that doing this is called using an Extender, but we can't find examples of how this works so far.

I'm curently developing web application which uses standard form authorization and, of course, server session objects (quite classic app). Now I'm developing client side component, which base functionality is to allow users to acquire tiif/jpg/pdf document from scanner (client side) and send it to server. Because of scan complexity and need for very user friendly interface i decided to implement Activex object (object written in .net 2.0). Until now all was ok, so I have got activex which succesfully registers and scan documents on client - but i cannot manage with sending files to server.
My concept of sending files was like that:
- preparing Upload.aspx web page wich is used for reciving files sended by POST method and saving files in database (of course to proper save in database i need some current user context information) - in ActiveX i decided to use System.Net.HttpWebRequest object to prepare and send data the problem was third point:
- i thought that in-proc activex object would "derive" web session form web page activex is placed on - but i was wrong (or i made it wrong). Whenever i send request form Activex, in response i got login.aspx page - so it looks that new session is created and new authorization is needed.
I was trying to pass to my Activex values stored in "ASP.Net_SessionId" and ".ASPXAUTH" cookies, as i found that these are the values identifying session and athorized user - but with no luck.
I think, that becaause HTTP is stateless protocol all information needed to "connect to/share" existing session on IIS server need to be included in request data, so there must be way to add these information to request sended from my activex.
I would be very grateful, if someone could provide me information what should i add (headres/cookies/etc... ?) to my request data so it could share session from "parent" web page.

My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

Here is the code I have so far:

When I click submit, It does the validation on the server side, I kinda like it to validate on the Client instead of taking a trip to the server right away.

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)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
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.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[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.

When I open my webpage locally on my computer, the webpage does not through any error but from the server, I get those: Message: ASP.NET Ajax client-side framework failed to load.
Message: 'Sys' is undefined
Line: 678
Message: 'Sys' is undefined
Line: 2542
In the web.config file I changed: <compilation debug="true"> to <compilation debug="false"> wich solved the first error(ASP.NET Ajax client-side framework failed to load.)
1. I wonder if that is okay to solve that error like that?
2. Then I wonder for the 'Sys' is undefined, what is causing that error. I googled and could solve the first error but this Sys error it seems to have countless of solutions that have not worked for me, so I might wonder what can cause this

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'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
