So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); }); $('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); }); and of course, my div in html like <div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?
I want to create a custom attribute to check if the browser has cookies and javascript enabled. I'm guessing I would create a ActionFilterAttribute that would redirect to a controller action to load a page to check cookies and javascript on the client side. If they are enabled then it would redirect to the desired action, otherwise display an error message. Is this a correct approach or is there a better way to do this?

I've got a bit of a problem UpdatePanelAnimationExtenders. Here's an example of the code structure I have:
[Code]....
Now here's my problem. When dd1 triggers the postback both dd1 and dd2 get disabled (instead of just dd1) and after the request is complete only dd1 gets enabled back. The behaviour is also true the other way around (if dd2 triggers the postback both dropdowns get disabled but only dd2 gets enabled back). I'm not really sure what to make of this.
I have an asp.net ajax enabled form that looks like this:
[Code]....

As you can see in the OnPreRender event, the Save button gets enabled or disabled depending on whether the datagrid is in edit mode or not. When I step in the code, it operates correctly in the code, but it does not get reflected correctly on the screen. That is, even when btnSave.Enabled set to true in the code, the browser displays the disabled button. Any idea why this might be happening?
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'.
There are tons of references for this error message on the Web, but I can't figure it out. The problem is that the application works fine when I run it locally or when deployed to other servers. There is just one server where I get this error during a post back from an Update panel (it is supposed to populate and open a popup panel). There is no Response.Write() anywhere in the code and the other either. I think. The next thing I will try is install the remote debugger. In the meantime, can someone tell me how to check if server trace is enabled (IIS 6)?
My only requirement is to find a selected pdf in a folder is Reader enabled or not, more specifically if usage rights are defined in a way that allows people to add annotations (e.g. comments).
I am doing this in windows application. If I click a button, an event is triggered searching a folder for PDF files. This event needs to check whether or not the PDFs in the folder are Reader enabled for comments. If they are, I need to remove the comment usage rights or revert the PDF back to its original version.
My code can only find PDF files in the folder. I don`t know how to check if the selected PDF is comment enabled or not.
private void button1_Click(object sender, EventArgs e) { { string[] filePaths = Directory.GetFiles("D:myfolderpdffolder"); List<ListViewItem> files = new List<ListViewItem>(); foreach (string filePath in filePaths) { ---need to check comment enabled or not--- } } }
So to ensure that javascript is enabled on a browser, you need to check wheather the returned valued is either equal to or bigger than 1. This works on normal browsers, but when I test it on my phone the returned value is always 0.0, no matter if my javascript is enabled or disabled. Is there a way to check if javascript is enabled on a mobile browser or will the browser handle the incapability on it's own?
In browsers such as firefox Sometimes on some users JavaScript can be enabled as false. In my website it is a bit compulsory to make it enabled=true. So On my page load I need to check the visitor's browser if it is enabled or not.
I am having a .aspx page which contains a checkbox,a button and atextbox which is in disable mode.When I check the checkbox then only the textbox need to be enabled.And after enabling if the textbox is empty and when clicked on the button an error msg should be displayed like "Textbox cannot be left empty"and this should be done dynamically.I dont want to add the requiredfield validator during design time instead I want to generate the required field validator when the button is clicked and msg to be displayed.
