View 4 RepliesI 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?

Now, how can I check from codebehind that Browser's Popup Blocker is enabled or Disabled and show such message.
How to find whether a user has enabled or disabled JavaScript in the browser or the browser does not support JavaScript?
View 5 RepliesI want to check if a mobile browser has javascript enabled before displaying a page to the user. The code I've found from my research is:
System.Web.HttpBrowserCapabilities browser = Request.Browser;
Response.Write(browser.EcmaScriptVersion.ToString());
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?

View 5 RepliesSys.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---
}
}
}
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.

View 1 RepliesI have a site created using .net and the ajaxcontroltoolkit. When some users log on they do not see the controls on the page. I can duplicate this if I disable active scripting in ie. The problem is that the users I have spoken with have active scripting enabled. I have had them navigate to a site that tests javascript and it passes. Has anyone experienced this problem? If so what was your solution?
View 1 RepliesI've searched high and low for some resolution to this problem. Hopefully someone here can explain!!I create a usercontrol that uses .NET web controls, but I want to create a smoother user experience by avoiding full postbacks, so I write some JQUERY to capture click events on the client and in this way do the processing without going back to the server.
$("#tblLedgerEntries :checkbox").click(function () {
var value1 = $(this).closest("tr").find("td.invoiceAmount").html();
var value2 = $('#<%=hdnTotalToPay.ClientID%>').html();
CalculateTotalPayable(value1, value2, $(this).attr("checked"));

Within an ASP.NET AJAX UpdatePanel on my page I have a submit button which has some custom javascript validation applied which set a global _cancelGeneralSettingsUpdate flag depending on the results of the validation.In this case the variable _cancelGeneralSettingsUpdate is correctly set to false but the initializeRequest function is not called before the page attempts to postback via AJAX, causing the postback to fail. I need to be able to have postbacks succeed once the invalid input has been corrected and the user clicks the submit button again. Unfortunately I do not seem to be properly wired into the PageRequestManager pipeline once postback has been cancelled. If I refresh the page, everything works again, but cancelling the postback via args.set_cancel(true)

View 3 RepliesI use AJAX controls a lot - AJAX update panels, AJAX-enabled grids, etc. (mostly from Infragistics), and most of the time, things work great. But sometimes they don't, and I have no idea where to start with debugging etc. The AJAX part of it is a black box (seemingly), and I really don't like that. I want to know enough about AJAX and javascript such that I have confidence to work with these controls instead of just praying that they work. I want to be able to debug them, and also have confidence that I am using them properly (because I don't feel I can possibly use them really properly and appropriately if I don't know what they are doing). What do I need to know to get this comfort? Where can I learn about this? How should I go about tackling learning about this?
View 3 RepliesI have a page that has 3 to 4 divs with gridviews in each that get data loaded using Ajax Xmlhttp calls.
Now the problem is that I have checkboxes in the grid and need them to be disabled/enabled
when they load to the main page in the div.
When i set the Enabled=false tag in the ASPX page to the checkbox, the UI throws an "Object required" error.
How do it exactly?
Measuring Page loading when javascript enabled / disabled
I know normally you call ConfirmButton from a control that does postbacks, but afew of my users don't have javascript enabled which is a showstopper.
So I'm trying to use a standard asp:hyperlink with a URL to the next page, and if the user has javascript it will call the ConfirmButton on the onclick event (and if returns true will follow the URL in the hyperlink).
If they dont have javascript, it will just follow the hyperlink without a confirmation.
This is similar to have a return confirm ("sure?") in the onclick event of a hyperlink, to fire a traditional js confirm
So far I have only got this:
<asp:ScriptManager
ID="man"
runat="server"
/>
[Code]....
how I can manually call the ConfirmButton with an onclick even in the hyperlink, and return true or false?
In my page, I need to enable a text box when user click on check box(checked). I have used javascript for this. It works fine but when there is postback for the page, the textbox becomes disabled again although the check box is checked. But the value in textbox still appears. Is there any method to retain the enabled state for text box on postback other than using hidden values?
View 4 RepliesScenario : I am going to access external web service [ExternalWS] using AJAX. So obviously, need to create local proxy service [LocalProxyWS] first, which in turn will access the external web service. Now, the external service webmethod [Process] basically redirects the current page on our site to their site, does some work and then return back to our site.
What I want : I want that when the user clicks the button ('Process') on our site, it should open a new window and then starts executing the request on the new window, so that I can have the page on my website to be displayed permanently (which will poll a request every 15 seconds to the external service (via local proxy) for the status).
Local Proxy service which calls external service is as follows..
[ServiceContract(Namespace = "LocalProxy")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class LocalProxyToExternalService
{
[OperationContract]
public void InitiateTransaction(string amount)
Basically, I am opening a new window from the button click and then want to process the new request in that new window, so that I can show the status to the user from the current page on my website So far, it opens the new window, but doesn't transfer the request on to that, but I get an error message in firebug as follows...
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?
In asp.net page, How can i call the javascript methods for form processing-submitting if the user browser supports javascript and use code behind events if the browser does not support javascript.I have the javascript code to send the form data to an ajax server page using jquery. Don't know how to invoke the needed one based on the browsers javascript availability
