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.

Hi, I am working on a web project, its mainly for the back office ppl. But the problem is, say I logged in to the application, and got the main menu I clicked on one of the menus, a new window appears for that menu. And if the user again clcicks on the same menu item, the window gets refreshed instaed of opening another new window. The other main thing is when I access the same application through other PC, Like say my pc uses http:\\localhost\\default.aspx and accessing the same link using other PC like http:\\OtheCompName\\default.aspx.....it gives conflict. It opens the window in the same window of the localhost PC rather than this PC's path http:\\OtheCompName\\default.aspx .......Any Help would be appreciated..!!
Thanks in Advance!

What would be the reason for using localhost, this should only really be used on one machine
Is there not a server you could put the app on and then people access it from there?

Hi thanks for the reply, I used the localhost just for an example...but if the Appplication is installed over two servers and if we access both the links from a same client PC then it would create a conflict as I stated in the first post.
Thanks Again for taking Interest.

I dont think you can do this
It might be better to use asp.net buttons and then use css to style the buttons to make a tabbed menu look.
You could use a panel as the area to display the information

thank you ...
i was also thinking the same ..

i mean that i fill my grid view with data by a dataset ..
then i add the grid view to a specific date cell for ex. (3-18-2008) ..
so the gridview will appear in the calender in the date 3-18-2008..
|

Are you trying to filter GridView or what else?!
I Love T-SQL
|
|
|
|
|
OK so you add the gridview to the calendar, you click on a date and a gridview should appear yeah?
Id it appearing?
What event isn't firing for the gridview?
|
|
|
|
|
The event is Gridview RowCommand .. I wanna fire this event when the gridview is in the Calendar ..
|
|
|
|
|
OK this is very vague so far.
What is exactly happening when you click on a date in a calendar, is the gridview displaying at all?
The row command should start when the someone click on the gridview yeah? Check that this command runs when it is not in the calendar
also post your code it might help us more

hey when my page is accessing through IE its looking fine but when i am using netscape navigator cotrols are moving to other places .. plz help me in this..
|

You need to be clearer about your problem.
Is this a page you have created that you are then viewing both in Explorer and then Netscape and it renders differently in both?
Very often pages will look different in different browsers: that is why the phrase 'cross browser compatability' was coined. Whatever design methods and styles you have chosen need to be reviewed and revised.
Without seeing your markup (I don't want to see it) I couldn't possibly guess what the reasons are. Suffice to say that you need to use a style or set of styles that will render correctly regardless of broswer. There are large numbers of sites that offer advice in this area. Go google.
