updatepanel

问题 I use UpdatePanel in my aspx page and DropDownList with onselectedindexchanged method. When run first time onselectedindexchanged method is working. But change selected again it return an error like that; Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: The state information is invalid for this page and might be corrupted. <asp:ScriptManager ID="ScriptManager1" runat="server" EnableViewState="False" EnableScriptGlobalization=

问题 In the following code... <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> <asp:TextBox ID="TextBox1" runat="server" OnTextChanged="TextBox1_TextChanged"></asp:TextBox> <cc1:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1" Display="Dynamic" ErrorMessage="This field is required"> *</cc1:RequiredFieldValidator> <br /> <br /> <asp:Button ID=

问题 I'm doing some straight up asynchronous calls from javascript using the XMLHTTPRequest object. On success, with certain return values, I would like to do an asynchonous post back on an update panel and run some server side methods. This is about how I'm implementing it now: <script language="javascript"> function AjaxCallback_Success(objAjax) { if (objAjax.responseText == "refresh") { document.getElementById('<%= btnHidden.ClientID %>').click(); } } </script> <asp:UpdatePanel ID="upStatus"

问题 I've seen this particular problem posted multiple times but none of the solutions I've seen actually accomplish what I'm trying to do. I have an ASP.NET page with an UpdatePanel on it. In the UpdatePanel is a button and a multiline textbox. The button's click event disables the button and enters a processing loop that updates the Text property of the TextBox multiple times. But, of course, the TextBox is not actually updated until the loop completes. I've seen suggestions to add a Timer

问题 First up, apologies for the length of this question! I have a page with several web user controls on them two of which are somewhat interdependent. In an ideal world they could be one control but for various reasons they need to be two. I need to update an update panel in one of the controls based on the action of a dropdownlist in another control, as described below. For this purpose we will call the controls JobControl and CallControl . JobControl contains a dropdown list, which is part of

问题 I am trying to show a progress image when I click an Imagebutton inside updatepanel. On button click c# code should run as well as show the update progress image. With this code, it runs the c# code but doesnt show the progress image, if i remove the postbacktrigger, then it shows the progress image but the c# doesnt run. Any idea how can I fix it ? <div id="scriptmanager"> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat=

问题 It's a common problem that jQuery widgets inside ASP UpdatePanels need to reinitialized after an ajax request, however my issue is that events are not unbound prior to replacing the HTML inside the UpdatePanel. jQuery takes care of this problem for you whenever you call .html("...") or .remove(), but the UpdatePanel doesn't utilize jQuery. I have popup elements (inside of the UpdatePanel), which need to be hidden when the user clicks outside of them so I made a jQuery Special Event for

问题 When the page initially renders, the initializeControl function is called and everything works. When the page performs a full post-back (via a submit button), the initializeControl function is also called and everything works. When there is partial post-back of the UpdatePanel , though, the initializeControl function is never called and the control stops working. HTML: <asp:ScriptManager ID="myScriptManager" runat="server" /> <asp:UpdatePanel ID="myUpdatePanel" runat="server">

问题 when my page loads very first time i see the watermark on the textbox but if any postback on the page, the watermark is cleared, is there a way to hold that watermark on the textbox? <head runat="server"> <title></title> <script src="scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="scripts/jquery.watermark.min.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { $("#txtEmail").watermark("Email Address"); }); </script> </head> <body>

问题 I have simple web user control (the code I found somewhere in the web): <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="WebUserControl1.ascx.cs" Inherits="ARP.DynamicsCRM2011.MagicWebForm.WebUserControl1" %> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged" Text="Checkbox" /> <asp:Button ID="Button1" runat="server" Text="Button" Visible="False" OnClick=
