I think but not sure, meta tag will work only when a page is in foucs. You need to refresh only from Master Page.

The Javascript Piyush Sardhara provided is clever and it would work, HOWEVER what it's doing would cause the equivalent of someone hitting the refresh button in the browser. For some pages that's fine. For other pages it's not. Your page's OnLoad( ) function would fire as if it were not a postback. The selections the user has made in text boxes and drop downs would be gone and the page would be reset. If you want better control over what happens when the page refreshes, you need to write a custom Refresh( ) method (or whatever you want to call it) for each page. Then you need to call this method somehow. You could do it the way I suggested earlier, or you could do it with an Ajax call or some other way. There is a drag and drop timer control you can put on your page. You set its properties to say how often if fires. Then you add an event handler to catch the timer event. It's easy, no more complicated than handling any other event like a button click.

hi, Do you know any idea about "Response.Addheader" concept ?

piyush sardhara · Answer

that scripts help to auto refresh page "text/javascript" language= "javascript" > var reloadTimer = null ; var sURL = unescape(window.location.pathname); function setReloadTime(secs) { //this function is used to refresh the broswer if (arguments.length == 1 ) { //if some seconds are passed in then create and set the timer and //have it call this function again with no seconds passed in if (reloadTimer) clearTimeout(reloadTimer); reloadTimer = setTimeout( "setReloadTime()" , Math.ceil(parseFloat(secs) * 1000 )); } else { //No seconds were passed in the timer must be up clear the timer //and refresh the browser reloadTimer = null ; //passing true causes the request to go back to the web server // false refresh s the page from history //This is javascript 1.2 location.reload( true ); //This is javascript 1.1 window.location.replace( sURL ); } } script >

you can use timer control and auto refresh to set time to auto refresh page

saravanan subramanian · Answer

Thanks for the reply. could you please give the sample code for the timer control. Thank you in advance. Regard Saravanan.s

Andrew Fenster · Answer

Well, yes, you need a timer control, but using it in a Master Page is tricky. You could put a timer in the Master Page that fires some method on the Master Page every 5 minutes. The Master Page could refresh the content that's actually part of the Master Page. But then it would still have to call the specific page and have it update itself. That part is tricky. I would create an interface, IAutoRefresh. Your individual pages that are going to update would implement IAutoRefresh. When the timer posts back to the Master Page, the Master Page would update itself, and then it would do something like this to make the specific page update itself. if (Page is IAutoRefresh) { IAutoRefresh currentPage = (IAutoRefresh)Page; currentPage.Refresh(); } If you don't want a particular page to auto refresh, you would not have it implement IAutoRefresh.
