I'm trying to write a templated user control that get's as a template the js code from the user,And minifies it on the fly (OnInit), and actually prints the minified JS.That means that I need a code that receives a string, and returns a string.All I found untill know are programs that uses the input output from the hard-drive, something that I can't allow.Is there any C# Libraries relevant to my issue need ?
View 1 RepliesI am working on a big .NET project. I am currently creating an automated minifier for JS and CSS files using YUI compressor. After doing some research, I found that the heaviest files in the project are actually .NET resources (Like MS ajax file). They are very big and unminified.I am wondering, is there any way to minify them?

I've installed Firebug and Page Speed minifying my HTML output. I'm also using VS2008, ASP.NET 3.5, AJAX, and IIS 7.5; along with URL-Rewriting. I want to minify my HTML, JavaScript, and CSS. Optimally, I'd like the minifying process to happen at compile time. I've spend hours looking online but couldn't find a decent solution,

View 1 RepliesThis program in asp.net 2.0 is a Spanish/English Dictionary.
It consists of two textboxes,one button and a datalist. The datalist is bound to an acces database consisting of two columns; One Spanish and one English. When a user enters a Spanish word in textbox1 and clicks the button, the meaning of the word appears in textbox2. Now sometimes a user enters a word that is not in the database. I want, in this case, to have a javascript messagebox to popup saying “Either the word is not listed or misspelled”.
I tried several javascripts to popup in code behind but that did not work. I know that a clientside should be included but I am not able to do that.
The sub below is the one I am using to fetch the words and it is working perfect as long as I enter a word that is already in access database. The words in the rows in database are separated by hyphens so I am using a “Split” fuction which is also working perfectly.

I wanted to disable a button after it is clicked and at the same time fire the post back event to generate a report. My first set of code did not work because soon after the button is disabled the page won't submit/post back. here's the first set of code which was not implemented. the onclientclick calls a javascript function which has these lines
document.getElementById('btnGenerateReport').disabled=true;
GetPostBackEventReference(btnGenerateReport,'');
since it was not posting back,i tried the following on page_load code behind
btnGenerateReport.Attributes.Add("onclick", "this.disabled=true;" + ClientScript.GetPostBackEventReference(btnGenerateReport, ""))
that worked well. but I tried to copy the javascript that got generated and pasted directly on design view
onclick="this.disabled=true;__doPostBack('btnDownloadClientsWithConviction','');"
its not working from client side alone after I disable the code behind attributes.add
but when I check the view source the 2 pages are the samewhy am I not able to move the code from code-behind to design view?

I've developing an ASP.NET application that interfaces with Google Maps and retrieves marker information from a database. The marker information is split into tables in the database, where the name of the table reflects a company (e.g. CompanyA_MarkerData, CompanyB_MarkerData etc). In order to periodically update the map with new marker data, I use setTimeout in JavaScript to regularly call my 'UpdateMarkers' JavaScript function. 'UpdateMarkers' makes a call to a web service which performs the database query and returns a list of markers back to the JavaScript, which in turn updates the map.
The main issue I have with this method is that my web service requires that I pass it the name of the company so that it knows which table in the database to access. As you can imagine , this poses a security risk as anyone can pass a different company name to the web service and be able to retrieve the data from other companies, as well as their own.
In order to avoid this problem, I am restructuring my program as follows: When the system administrator creates users for my application, they can also assign a company ID to this user. The company ID is stored using the Profile object in ASP.NET. I am moving the web service code into a class with shared functions so that they can be called only within my pages (but not by anyone, like with web services). The functions will still require a company name passed to be passed to them. However, rather than the JavaScript making direct calls to these shared functions, the JavaScript will call a set of page methods (which as I understand it, are not public like web services). These page methods will then use the Profile object to retrieve the company name attached to the user currently logged in and then make a call to my shared database functions and return the info back to the JavaScript.
I think that this second method is more secure than the first, because I don't allow the client to pass different options to my code and retrieve unauthorized data. The server side code works out the parameters that need to be sent. However, I am wondering if there is a better way of doing this that I am missing out?
how to call code behind from javascript without postback ?
View 7 RepliesMe with C# asp.net I am displaying a pop up window using javascript in the page load like
<body onload ="Popup.showModal('modal')">
I want to call this popup in the code behind
protected void Page_Load(object sender, EventArgs e)
{
want to call it here
}
how can I write JavaScript code in asp.net in code behind using C#.
For example, I have click button event when I click the button I want to invoke this java script code:
alert("You pressed Me!");
I want to know how to use java script from code behind.
I have a web application that will need to access code behind methods as well as javascript methods. For this particular implementation it doesn't really matter which order they are called in from a program flow perspective.
I'm looking for insight into when it would be appropriate to use a code behind to call javascript and when it would be appropriate to call javascript from a code behind. Are there any ramifications of doing it one way or the other that I should be aware of before moving forward with an implementation?
Is there a best practice way to do it or is it very specific to the actual implementation?
Some time ago (like 3 or 4 years) I heard about ability to generate JavaScript (client) code based on C#.NET source code. I don't remember details, probably that was for validation purposes only.

and this is the code behand of btnPreviwe onclick event:

as you can see, when the btnSave is clicked, it is programmatically clikced the btnPrevew first, and btnPreview registers and fires the required JavaScript. But actually once the btnSave clicked, it does go to the btnPreview_OnClick event, but for some unknow reasons, the javascript in btnPreview_OnClick doesnt work, however, when i just put cstext2.Append("alert('hi')" instead of cstext2.Append("'SaveSignature()'", the javascript does executed, and also if i modifed the asp.net code for btnPreview to this, it works too.
