Recently, I added a button, a textbox and a jquery code. On click of button the textbox value was been captured in the dropdown. All my code is working fine. But, when I fill the other data and submit the form, It gives me the below error.
Also see the code for reference:-
<script type="text/javascript">
$('#ctl00_ContentPlaceHolder1_txtOtherBusiness').hide();
$('#ctl00_ContentPlaceHolder1_btnbusinessAdd').click(function (event) {

Getting an error whenever we click a particular button/link on our site. It is generating a javascript "Invalid Argument" error. I know in the other posts it is typically because it is a syntax error in the javascript however it only just seems to have started happening and it doesn't happen on all pcs.
ie. in our client's environment if I remote onto their web server and view the uat website I get the javascript error. If I remote onto their sql server and view the uat website I don't get the javascript error. If it was a syntax error then I would always get the error wouldn't I?
both browsers are the same version of IE6 (yeah I know...) :) I have tried deleting temporary internet files - including viewing the files and deleting them myself - but no joy.
client uses citrix.. and they're all getting the error :(
Update - I haven't posted specific code as there is too much to post (and I'm not sure where the error is occurring). The "button" launches a new window which in turn opens up a couple of aspx pages and calls lots of javascript. So the window opens ok, and there's a function that gets called to resize the window - but before it calls the resizing of the window/content it throws the invalid argument error. Am busy trying to get alerts to trigger to see if I can see where it's falling over but so far no luck.
Again not sure why this error doesn't occur when I use a particular PC (same browser version)
I am making a call to a WCF service(Existing) from another WCF Service(New, my service), which is configured as Anonymous access. I did a service reference of my service to web application both under same solution file and web app is configured as Windows Authentication. When I call the existing WCF Service from my web app directly, everything works fine, but when I call the same existing WCF Service from my service, I got a "user does not have valid credentials" error. To avoid this error, I published my service to a server and referenced that URL to my web app. Though I got past the error, now, I am getting "Invalid Argument" error. No further information on the error.
Error source is MSCORLIB. There is no problem in the code of my service and the existing service, because if the same value that I get from the existing service is hard coded, then everything works fine. The existing service is used by many other app and it works fine. So, its a tested service. I tried to find a solution of "invalid argument" and I found few threads where others are facing the same problem when they publish a WCF service, but I did not find any proper solution for this.

I have searched high and low on this error, but my problem stems back to which control is causing this problem. In theory the problem starts when someone goes to a specific tab and clicks a button to download a PDF file. After doing that if I use a dropdownlist the error pops up.I have checked the code etc. just cannot figure out which control is triggering the error. I can identify the control that is the problem?
View 14 RepliesI have a a dropdown on a page
<asp:DropDownList ID="drpName" AutoPostBack="true" AppendDataBoundItems="true" runat="server" ></asp:DropDownList>

When I select the items that have been added and it does a postback I get the following error:

i have had this problem before but haven't found a solution yet. The solutions that i have come across are either bad for security or worked on old versions of the .Net framework. I am using VB.net with framework 3.5 and i get the following error when clicking on a button that is a trigger for an updatepanel:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.

If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
The msg states that you need to use the ClientScriptManager.RegisterForEventValidation but i can't find anywhere which shows a working example of this in VB.net & in .net framework 3.5. Can anyone give me a step by step guide on how to resolve this postback validation error?
I have a TabContainer that has a button in one of the tabs. When i click on the button, I need to save a few items to the database and then select a different tab.
I have tried coding this tab change like this:
this.tcItems.ActiveTabIndex = 1;
And like this:
AjaxControlToolkit.TabPanel tabTwo = (AjaxControlToolkit.TabPanel)this.tcItems.FindControl("tabName");
this.tcItems.ActiveTab = tabTwo;
In both instances, I receive a scripting error message "Invalid argument." from the file "ScriptResource.axd".
After continuing or ignoring these errors (ussually three of them), the page finishes refreshing and the correct tab is selected. I'm just not sure how to get rid of these error messages or why I get them.
I have this following code but it gives me "invalid argument" error when I click on the 'a tag'. what is my mistake ?

I'm having this wierd issue I hope you could help me with.I have two drop down lists in my page, and an accordion.When a value is chosen for the first DDl it loads specific values from my database into the second ddl.I've put the second one inside an Update panel, and added the first DDL as AsyncTrigger, so whenever someone chooses a value from the first DDL it loads the second one without refreshing the page.After a value has been chosen for the second DDl the accordion should be populated with data.I've ran some tests and noticed that choosing a value from the second DDL won't populate the accordion, so I've added another PostBack trigger to the second DDL- the ddl itself.Sometimes it works fine- I choose a value from ddl2 and the accordion shows fine, but sometimes I get this error message:Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."Before putting the second ddl inside the update panel everything worked well so I'm a bit baffled here.
