问题 I'm working on an ASP.NET web forms application. In my Page I have an UpdatePanel and a user control with an UpdateProgress and a bunch of buttons. When the user clicks one of the buttons, I'd like to perform an asynchronous postback and show the UpdateProgress . Can anyone help me with making the postback asynchronous (looks like it works) as well as making the UpdateProgress appear (doesn't work yet)? Usually, this can be done pretty easily by defining an UpdateTrigger in the page markup.

问题 We have several pages in our ASP.net Ajax application which auto refresh the UpdatePanels contents based on a timer event but the problem is that we have a requirement to timeout the web session and the auto refresh is preventing that. Is there a way to prevent the timer postback event from modifying the web session or any other alternate solution to allow the web session to timeout while auto refreshing the UpdatePanel contents? Here is an example to illustrate this problem. I set the

问题 Is there a way to detect when an update panel is done refreshing? I want to fire some javascript methods when the update panel is finished. Perhaps via the UpdateProgress control? 回答1: You can use: Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function EndRequestHandler(sender, args) { // do what you want here } Of course, this will caputure every AJAX EndRequest call so you'll have to make your EndRequestHandler function see what has been requested or play

问题 I'm trying to get an aspx datagrid control to perform a post that results in a partial postback (asynchronous) rather than a full postback. I've added scriptmanager, an update panel, and a content template wrapper and yet it still refreshes the page when i select a data item and click add. <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="True" ></asp:ScriptManager> <asp:UpdatePanel ID="upPnlLookup" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="True">

问题 In an asp.net/c# application, I have an update panel on my main page. And everything on the page is updated via the update panel. So there is only one page and all the changes are made in update panels using asynchronous postback (partial postback) My question is: Is there a way to make the browser BACK button works and return the page to it's previous state? Hope I was clear Thank you very much for any help more info: I tried to implement this http://rchern.wordpress.com/2008/05/11

问题 I am making a web application. I have gotten a weird error with update panels. Ok, so say you have two update panels and each update panel has a textbox in it. Both of these textboxes are auto-postback and the update panels update conditionally. Well, from the behavior I'm observing it seems like if the server isn't faster than the user at processing a request then it sorta gets ignored on the client side. Like say you type something in 1 of these text boxes and then quickly tab to the next

问题 I have a gridview in an updatepanel with sorting enabled and an event handler as follows: protected void MyGridSort(object sender, GridViewSortEventArgs e) { var TheDirection = (e.SortDirection).ToString(); var TheColumn = (e.SortExpression).ToString(); } I put a breakpoint just after these lines. Every time I press the column header, my variable TheDirection is always showing Ascending. Why is it not toggling from ascending to descending and back? Thanks. 回答1: You could keep the direction in

问题 I have a form with update panel and containt a gridview.
