updatepanel

问题 In reference to my question, Page.Unload Event inside a Update Panel I am able to make it work but I got two buttons that do partial post back and then in my script I can do what I want, but I want it to work for just one button not two of them, best thing is button I want to make this request work for is Image button whereas other button is just a simple button. This is a User Control in ASP.NET by the way. <script type="text/javascript"> // if you use jQuery, you can load them when dom is

问题 I have the following code inside of an update panel. When the screen loads, the SignalR code works fine. However, after the first time, once I click a button, the SignalR code does not fire anymore until I cause a redirect back to the page. Basically what I am doing is when the user clicks the preview button, it fires off the reporting process. An Ajax modal popup is displayed with a progress indicator and a cancel button. If the user clicks the cancel button, the cancelation token is set,

问题 I have this UpdatePanel I want to use in my website. Basicly the idea is that a user clicks on a link and start a service on the server that will change a database. So what I want to write is a method that wil return true or false if the database is updated. The method should run on timed intervals. If the database has been updated it will return true and that should trigger the UpdatePanel to update. I know you can add triggers through controls. But is it possible to do so through code as

问题 I'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls. protected override void OnLoad(EventArgs e) { base.OnLoad(e); RenderDynamicControls() } private void

问题 I haven't started writing any code for this program, but here's what I need to do in C#/ASP.NET, both of which I'm just starting to learn. I have a DIV on a page that I want to update with information from an MS SQL Server every five seconds. Would it be better to create my countdown timer on the JavaScript or C# side? Would UpdatePanel or creating a Page Method be more efficient for updating the DIV with the database information? Load times are a serious issue for this application, so the

问题 i have two buttons inside a update panel.i need to trigger update progress and show a .gif image for each button click.when i press a button1 only the associated update progress should be displayed and the other one should be invisible 回答1: You can associate the UpdateProgress control with a single UpdatePanel control by setting the progress control's AssociatedUpdatePanelID property. In that case, the UpdateProgress control displays a message only when a postback originates inside the

问题 I have an update panel in my page which runs a function and sends an e-mail fine but when I added in the code below it doesn't seem to add it correctly to the page Page.ClientScript.RegisterClientScriptInclude("myscript", "/scripts/myscript.js") All the other stuff in my Sub runs fine but it just seems to not run that bit? Any ideas? EDIT Here's my code <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="button1" EventName="Click" /> </Triggers>

问题 Apologies for such a broad, sweeping question, but I can't really give specific code examples because as far as I can tell from research this problem is unique to the particular page I'm working on and if I knew what to do to replicate it then I'd most likely be able to fix it. I have an asp.net vb (v3.5 using the ajaxcontroltoolkit v4) page essentially binding some straight forward SQL database data to a gridview. The gridview's in an update panel and whenever I do anything that causes a

问题 I have a webform with two upload controls and a number of textfields. When the button is pressed the files get uploaded and then get processed. The upload takes no time, but the processing does. I know I can't have an upload control in an update panel, so I can't work out how to use the update progress control to show my progress. My page with an updateprogress control that does work is as follows: <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:UpdateProgress ID=

问题 I have an update panel that includes a gridview. This grid has a drop down list column.
