由 人走茶凉 提交于 2019-12-04 06:41:03
问题 I am creating an MVC app where the user can add items to their cart. They can also make partial payments on certain items so I have a TextBox for them to specify how much they want to pay. I am using an Ajax ActionLink to handle the Update/Add to cart actions so that I can increment the cart count without refreshing the screen using a partial view. My issue is that I can't find a way to pass in or access the value entered in the TextBox to my PartialViewResult function. Here is my Model...

When I make a jQuery AJAX JSON request, it responds with a "d" attribute. Why is this? here a good article about it http://encosia.com/2009/06/29/never-worry-about-asp-net-ajaxs-d-again/ “.d” what? If you aren’t familiar with the “.d” I’m referring to, it is simply a security feature that Microsoft added in ASP.NET 3.5’s version of ASP.NET AJAX.

Why is the form action attribute empty on production server?

由 丶灬走出姿态 提交于 2019-12-04 04:46:48
问题 After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem: xmlRequest.open("POST", action, true); The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like: <form method="post" action=

How to get the id of Updatepanel which initiated a postback

由 徘徊边缘 提交于 2019-12-04 04:45:45
Hi I need to intercept server callback after udate panel async post back and determine which panel initiated the request. The code is pretty simple: Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(InterceptUpdateCallback); function InterceptUpdateCallback(sender, args) { var updatedPanels = args.get_panelsUpdated(); for (idx = 0; idx < updatedPanels.length; idx++) { if (updatedPanels[idx].id == "myUpdatePanel") { StartSmth(); break; } } } And it works when UpdatePanel is not inside another UpdatePanel. But when it is inside another UpdatePanel updatedPanels[idx].id has parent

问题 I have three updatepanels in hierarchy: UpdatePanel1--Root UpdatePanelChild1 UpdatePanelChild2 Can I update a control in updatePanel1 on an event of the updatepanel2? 回答1: I'm not a big fan of every updatepanel updating all the time - that seems to undo the locality update panels get you. Another option is to specifically call the .Update() method of the OTHER update panel in your code. For example, suppose you have a button on UppdatePanelChild1 that does some processing and modifies a

问题 I have an ASP.NET page that uses the ASP.NET Ajax Control Toolkit TabContainer. In the Page_Load event, I am hiding some of the tabs based on the data given to the page.
