asp.net-ajax

问题 I'm trying to add a realtime progress report to my c#/asp.net 4.0 application for a slow loading page. I've look at the UpdatePanel and UpdateProgress Ajax controls but I don't think they're suitable. Basically when the user click a button the page executes a number of tasks, I'd like the user to see an update as each one completes, instead of a report when they all complete and the page load completes. The order thing would happen would be: 1. user click button to start 2. call method 1 3.

问题 I'm trying to execute JQuery after an ASP.Net Microsoft AJAX post back. When a user clicks on a link, Microsoft AJAX is used to update some fields in the DB and if success a label appears informing the user the change has been made. Unfortunately the label is not very obvious and I would like to use to fade the background from red to white. The problem is that when visible=false is set on the label, the resulting html does not include the label(span). Does anyone know how to execute JQuery

问题 I'm using the Ajax.BeginForm helper in my MVC app. Here's a simplified example: <% using (Ajax.BeginForm("actionName", new { Controller = "controller" }, new AjaxOptions { OnBegin = "doValidation", LoadingElementId = "ajaxLoader" })) { %> The problem is that if the OnBegin callback returns false, which correctly prevents the ajax call from being made, the loading element "ajaxLoader" is still displayed, and not hidden. I've tried using the OnFailure and OnComplete callbacks, but neither of

问题 I've got a web application working using VB and Ajax. I'm using updatepanels to avoid the irritating "flicker" on postbacks to the server. I would like to have a button control defined within the updatepanel itself (tried moving it outside and got some catastrophic error, so left it there) that makes the current panel not visible and a sibling panel visible. This works with the exception that the button must be clicked twice. Not double clicked, but clicked once than clicked again. In setting

问题 Hope someone can help with this. I've been up and down the web and through this site looking for an answer, but still can't get the Autocomplete AJAX control to work. I've gone from trying to include it in an existing site to stripping it right back to a very basic form and it's still not functioning. I'm having a little more luck using Page Methods rather than a local webservice, so here is my code <%@ Page Language="C#" AutoEventWireup="true" CodeFile="droptest.aspx.cs" Inherits="droptest"

问题 I've read through the net but haven't found a solution to the following problem. I have this example page (_ScriptManager.aspx) with a ScriptManager , an UpdatePanel , a MultiView with two Views and two LinkButtons two switch between the views. The second view contains some functionality which I want to load a JavaScript file for (_ScriptManager.js). Since I don't know whether the user will ever visit view 2 I don't want to include the javascript file statically on for every request. I only

问题 I am trying to submit an Ajax.BeginForm using an hyperlink as opposed to a Submit Button. I tested with the submit button and the action recognizes the post as Ajax based by test Request.IsAjaxRequest, however if I try the following IsAjaxRequest returns false: <a href="javascript:void(0)" onclick="javascript:document.forms[0].submit(); return false;">Update</a> 回答1: The form is hooked into Microsoft's Ajax library, so you can't just call form.submit() because the wired up ajax events aren't

问题 First time working with UpdatePanels in .NET. I have an updatepanel with a trigger pointed to an event on a FormView control. The UpdatePanel holds a ListView with related data from a separate database. When the UpdatePanel refreshes, it needs values from the FormView control so that on the server it can use them to query the database. For the life if me, I can't figure out how to get those values. The event I'm triggering from has them, but I want the updatepanel to refresh asynchronously.

问题 I had an ASP UpdatePanel to update a gridview which worked fine, now I wanted to also use AjaxControlToolkit for some of the controls in there, but after wiring up everything when I run I get an error "Only one instance of a ScriptManager can be added to the page." inspite of the fact that I commented off the ASP ScriptManager and am using the toolkitscriptmanager. however please note that I am still using the ASP UpdatePanels. <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat=
