I've got my validation wired up through my Service layer, and my Birthdate property looks like this.
[Code]....
The client side validation works properly if I input something like `12/12/1990` but when the form is submitted, the server side validation trips and I'm told the entry is invalid. I'm using the jQuery-UI Datepicker to input the date, however when I disable the datepicker, the problem persists.Am I missing something here? I thought the client side and server side would be the same thing.If I remove

Then the form submits. It's obviously something to do with the Regex.

My problem is that once the data submitted to their site my page receives a response code. (1 = Member Added, 2 = Updated Member...)
How do I go about capturing this response code? Currently I end up with a blank page and a number in the upper left corner.

Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated -

For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.

i have issue with browser close prompt;
"the webpage you are viewing is trying to close the window"
in ie6 i prevent this by using coding
self.opener = this;
self.close();
in ie7 and ie8 i prevent this by using coding
window.open('', '_self', '');
window.close();
but, problem is which code will prevent for all brower(ie6,7,8) asking the message.
The web app in question provides a UI for editing a client (in the business sense, not the browser sense), identified by a ClientID. I store the ClientID in Session, which gets passed from page to page, along with a number of other pieces of data in Session. Works great.
The problem is that if the user opens a new browser window using Ctrl N or File->New Window (in IE), the new window comes up with the same page as the current page, with the same session info. Then if the user navigates to a different client in the 2nd window, the ClientID in session refers to the new client. If they go back to the original browser window and save, the original client gets saved using the 2nd ClientID, and all hell breaks loose, because now the data from the two jobs are intertwined.
I have enabled trace and verified that the new browser window uses the same SessionID as the original. If an entirely new instance of IE is opened, it has a different SessionID, so is not a problem. I have not yet investigated other browsers, such as Chrome or Firefox.
Is there any way to determine if a browser instance is opened for a web app which is already open in another window or tab? Or to prevent that from happening?
My problem is am filling a form in a webpage, and click on save for instance, take the URL of mu webpage and paste it in a new window and it loads all the information I subscribed, how can I prevent that knowing that I used the Below code and it does nothing
I need to know how to add a randomly generated token as an additional parameter in my request.

i just like to ask if you have any idea of preventing the Back button of the browser to navigate back to the previous page after a user log in.Ex:After a user successfully logged in to my website and he/she hit the Back button of the browser.I want this to not redirected to the previous page instead redirected to the same page which is my Main page.Also after a user logged out to my website and again he/she hit the Back button of the browser.I also want this to not redirected to the previous page instead redirected to my login page.

View 6 RepliesI have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
Edit
I've accomplished this by doing the following:
protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}

View 2 RepliesI have use fckeditor in asp.net. When user open the page containing fckeditor in Chrome. User can resize the text area of fckeditor. I want to prevent this.i.e.user should un-enable to resize the text area.
View 2 RepliesSo its a ASP.NET problem where two users using the same machine, same browser:
User 1 logs in the domain.
User 1 changes some data without saving it.
User 2 logs in the domain in a separate tab.
User 1 switches back to his tab and saves the data.
User 1 actually saved the data into User 2!!
This is caused by the following mechanism:
Different tabs in the same browser seems to share the same session id.
We are storing user auth in cookie and the cookie is shared between tabs (same domain)
Therefore, when User 1 request to save, it is recognized as User 2 since the cookie has been updated to User 2.
So I'm wondering if there's any other methods to prevent this from happening, other than:
1. Use cookieless session so the session is embedded in uri.
2. Always include a hidden field in page to indicate which user owns the page.
I have ASP.net application that is basically a data entry screen for a physical inspection process. The users want to be able to have multiple browser windows open and enter data from multiple inspections concurrently. At first I was using cookie based sessions, and obviously this blew up.I switched to using cookie-less sessions, which stores the session in the URL and in testing this seemed to resolve the problem. Each browser window/tab had a different session ID, and data entered in one did not clobber data entered in the other.
However my users are more efficient at breaking things than I expected and it seems that they're still managing to get the same session between browsers sometimes. I think that they're copying/pasting the address from one tab to the other in order to open the application, but I haven't been able to verify this yet (they're at another location so I can't easily ask them).Other than telling them don't copy and paste, or convince them to only enter one at a time, how can I prevent this situation from occurring?
