Feb 13, 2010I have a masterpage with a timer that shows server time and refreshes every second, on the content page I have a chat program with ajax, refreshes every to second to get the last messages entered.
I have a Html TextBox and a hidden Submit Button, when user write a text, and hit the enter, I check to see if this is the enter key and then submit the message,it is working perfectly in IE, but in FireFox and Opera it show the same message twice.

View 7 Replies.net - Change <body> ID With Javascript From Within ContentPage?
Sep 23, 2010I'm looking to do a short term hack on a site. The site is a ASP.NET site with a master page. The body tag is in the master page. I'd like to specify which ID should be in the body tag from within various content pages. What I don't know is if you can have this type of access to the body tag when your JS is within the body tag. For various reasons, I'd like to try to accomplish this in JS, not .NET.
Rephrasing for clarity: I would like to use JavaScript to specify a body ID from within the body tag of a site. For example:
<body id="MyID">
JS to change MyID to another name

View 2 RepliesState Management :: ViewState - Does The Master Page Have Its Viewstate
Apr 30, 2010I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?
C# - Page With ViewState Disabled Still Be Validating A Viewstate Field?
Sep 24, 2010I have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.

View 2 RepliesC# - Maintaining Viewstate With Get?
Mar 11, 2011Upon page reloads I want to retain the values the user had typed in upon hitting submit. I worry about viewstates being cumbersome for pages, both in bandwidth and in time for a page viewer to download the page. I am cheap with my bytes :p
My question is instead of using server controls and such I am having the form on the page do a get to itself and on the aspx putting <input type="text" id="user_email" name="email" value="<%=Request.Form["email"] %>" /> This allows me to not use viewstate. Are there any potential shortcomings to doing things this way? My goal is always for a lighter page and efficiency even if it is more work.
