updatepanel

问题 I'm programming a Forum. My showcomment.aspx page, I use Repeater to get comment from SQL Database and display them in each topic. I use UpdatePanel to auto update the new comment inserted in Database. <asp:ScriptManager ID="ScriptManager1" runat="server"/> <div onclick="__doPostBack('UpdatePanel1', '');"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" OnLoad="UpdatePanel1_Load"> <ContentTemplate> <asp:Repeater ID="RepeaterComment" runat="server"> .... </asp: Repeater...> </ContentTemplate

问题 I have a file upload inside the update panel, and an upload button that uploads the file to the server. Is it possible to upload the file without clicking the upload button?

Or, have a 4 second timer, then call the upload_click to check if the fileupload has a file or not. How can I do it without a button inside update panel? <asp:UpdatePanel ID="UP_DDL" runat="server" UpdateMode=

问题 I don't know if this is the effects of an update panel or what, but I basically have a drop down list that allows a user to select an item as a filter.

问题 I have an aspx page. On the page I have a javascript function window.onbeforeunload = confirmExit; function confirmExit() { return "You have attempted to leave this page. If you have made any changes to the fields without clicking the Submit button, your changes will be lost. Are you sure you want to exit this page?"; } This executes when the user leaves the page.

问题 I have a form containing a list of input fields that the user populates with prices (numbers). I have set their css classes to "required" and "number" so that the jQuery validation plugin validates them accordingly. All that is working perfectly well. The errors are displayed when each field is either not a number or the value is missing etc. This entire form is actually inside a nyroModal (jQuery plugin) model popup window. But that shouldn't matter, its just an .aspx web form regardless.
