问题 I'm implementing noCAPTCHA reCAPTCHA into an existing form with VB.Net. It is located within an UpdatePanel and uses server side validation to verify the user has completed the CAPTCHA (See Validating Recaptcha 2 (No CAPTCHA reCAPTCHA) in ASP.NET's server side) If a user fails to the CAPTCHA or any other of the validated fields, the CAPTCHA fails to reload due to postback. How do resolve this and make it so that the CAPTCHA does not disappear after a postback? My CAPTCHA code: <div id=

问题 I am creating an enterprise web template to be used for development of all our web applications. Many of our existing applications take a while to load because of the amount of data and geographic distance of the data source, so users frequently click the same buttons and links twice. I plan to add a Please Wait message to come up when the page is posting back. I figured there are two obvious ways to do this: 1. AJAX Tools Using the AJAX UpdatePanel and progress loader, I can easily show a

问题 I am using an update panel . In this update panel, there is a listbox control. I actually set autopostback property to false in code behind. But still it executing SelectedIndexChanged event if the selected index is changed. Why this happens? <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:MultiView ID="mvForms" runat="server" ActiveViewIndex="1"> <asp:View ID="View1" runat="server"> <asp:Panel ID="Panel5" runat="server" GroupingText=

问题 Ok my first post and i hope the title makes sense. I have an updatepanel, and inside it resides a fileupload control with a button to trigger an upload. Beneath that i have a ListView which is databinded in the behind file with a list of files that is uploaded. The updatepanel has a "PostBackTrigger" pointed to the upload button. All of this works just as it should. For each item that is listed, there is a linkbutton which deletes that specific file. That also works as it should BUT here is

问题 I have got a grid[Grid1] that build its dataRows when a button[search] is clicked, I managed to Ajaxify it by placing it in an UpdatePanel and it worked fine. Before Ajaxifying Grid 1, another grid[Grid2] and some other controls[Text and Labels] used to get populated/updated when a row in Grid 1 was clicked . The Grid2 and other controls used to get populated/updated on the OnItemCommand Event of Grid 1.Its the code in the OnItemCommand that binds the related data to Grid2 and other controls.

问题 I have an asp.net page which has amoungst some basic labels etc, and an updatepanel containing a dynamic list of UserControls. Each control has its own UpdatePanel, and basic controls. I have hatched together a collaps/expand feature for these controls and has been working fine to date. To make the page more efficient I have been working to 'Async-ify' the heavy data processing that happens during load, to display in these fields and user controls. After all of these changes everything still

问题 I have a problem with this that works for one button and not for another. The one that works is a button that calls a ModalPopup to add a new row to a GridView inside an UpdatePanel. If it's successful, it pops up an alert with a message, else another alert with the Exception message. The code is very similar to the other one's, except it's in a ModalPopupExtender. The button that throws the known exception about the EventValidation goes as follow: Web: <asp:Button ID="btnAlquilar" runat=

问题 I have some Update Panels on a webpage all set to UpdateMode="Conditional", however when the AsyncPostBackTrigger on one of the Update Panels is triggered, all of the Update Panels refresh. The following is one of the update panel HTML markup: <asp:UpdatePanel ID="pnls1FieldUpdate" runat="server" UpdateMode="Conditional"> <ContentTemplate> <table class="FillInGrid" cellpadding="0" cellspacing="0"> <tr> <td> <asp:TextBox ID="txtS1ExpDate" runat="server" Width="67px" TabIndex="14"></asp:TextBox

问题 While doing asynchronous postback page losings gridviewscroll script even after i did script register on code behind. (I have grid in update panel.. This happen when clicking "add new row" in asp.net grid view.) I have tried with the following three methods. ScriptManager.RegisterStartupScript(UpdatePanel_Objective, this.GetType(), UpdatePanel_Objective.UniqueID, "gridviewScroll();", true); ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "script", "gridviewScroll();", true);
