问题 I would like to trigger a PostBack when the asp:LinkButton "addToCartButton" is clicked (see code below). I have declared a PostBack Trigger with the asp:UpdatePanel "updPnlProductsList" (see code below). <asp:Panel ID="pnlProductsList" runat="server" Visible="false"> <asp:UpdatePanel ID="updPnlProductsList" runat="server" UpdateMode="Conditional"> <ContentTemplate> <div class="featured"> <h3>Product listing</h3> <div class="product clearfix"> <asp:DataList ID="productsList" runat="server"

问题 I have an ASP.NET form that the user can make lots of changes to, each time they make a change the page PostsBack and the details are updated. If the user hits the browser back button they go back through all the previous versions of the page. Is it possible to stop each PostBack being treated by the browser as a new page? So the would make any changes they like and if they hit the back button it brings them to the previous form and not the same form but a different version? I know I could

问题 How do I check which LinkButton is clicked in the Page_Load of the page. This is to avoid calls to service so that it only executes what is present in its event. 回答1: The only thing that should be running in your Page_Load is the code you want to happen always with everyt request, OR have the code that you only want to run once wrapped in a post back check. For example: protected void Page_Load(object sender, EventArgs e) { // Put the all code you need to run with EVERY request here // Then

问题 So, I've been trying to get this page working for a couple of days now, when I clicked the send button it would work, but if you tried to hit enter it would just do a postback to the same page. Yesterday I thought I finally got it so it would work on chrome (it has been working just fine on firefox, but breaking on chrome/safari and it is an app for the iphone). But, even though I finally got it so it would change pages, it is now displaying an error. I narrowed down the cause to a postback

问题 I have a CheckboxList that seems to load and do everything right, except for when I do a postback, it will not have the Item.Selected property set. I have viewstate disabled for the entire page. I load it like so(inside Page_Load on every load): foreach (DataRow service in d.Tables[0].Rows) { cblServices.Items.Add(new ListItem((string)service["description"], service["id"].ToString())); } My markup is simple: <asp:CheckBoxList runat="server" ID="cblServices" Width="300px"></asp:CheckBoxList>

问题 I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet: $("#MyList_btnAddAll").click(function(e) { e.preventDefault(); $('#MyList_lstAll option').appendTo('#MyList_lstSelected'); }); The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as elements, as you'd expect. The jQuery is working great, the items are moving
