| Re: shouldn't the DIV remember this? Are you setting ScrollLeft using JavaScript or during a postback? If you are setting it using JavaScript it will not be remembered because the JavaScript will not modify the ViewState. It may also be helpful if you showed us your code. -- Nathan Sokalski njsokalski@hotmail.com http://www.nathansokalski.com/ "rodchar" <rodchar@discussions.microsoft.com> wrote in message news:A102FB1B-8EF2-475A-85FE-176DD042CAB8@microsoft.com... > hey all, > i have a div on my page where i set the ScrollLeft value. when i do a > postback the div is set back to 0. i've made the DIV runat server and > enabled > viewstate. what would i have to do to make this work? > > thanks, > rodchar |

| Re: shouldn't the DIV remember this? There is no way to have ViewState remember values set using JavaScript, but what you can do is create an <input type="hidden"> and set the value property as part of the function. Then when you postback you can have ASP.NET use that value when generating the returned page. This is usually the best way to avoid losing values set by JavaScript.
