I have a form that the users fill out and submit, sometimes there is an error and I need to delete the submitted data from the

I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.

I have a web app that needs to do two things at the same time. After a user clicks a button on the site, a javascript function needs to execute and while thats working I need the server side code for the button click to execute without waiting on the client side to finish.
To be more specific, the client side function takes about 23 seconds to complete, and while that is running the server side code promts the user for printing a document. So I need the javascript to run "in the background".
I use a js function in a source page as below
<a href="javascript:;" onclick="openwin('Sample.aspx?DID=<%#Eval("UID") %>', '', '700','300','yes'); return false ">
I need to excute this function from vb.net code behind page .

View 1 RepliesExecuting Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>

I have a web app which displays some data in a GridView. This GridView is populated with a method called BindGrid. The user selectes one or more rows from the grid, then clicks the Process button. What needs to happen is that the selected rows are assembled into a CSV file which is downloaded to the browser, then the database is updated to reflect which rows were selected, and the grid is refreshed so the previously selected rows are no longer displayed. This all sort of works, except...
My code is below, which is very similar to lots of snippets found in this forum.
The problem is that if I uncomment Response.End(), or replace it with ApplicationInstance.CompleteRequest, it all works great except none of the code after Response.End() executes, and so the log entry is not made and the grid is not refreshed.
If I comment Response.End(), as in the snippet below, the code following does run, including the log entry and the call to BindGrid. (I know that because log entries inside BindGrid are made.) However, the page does not refresh. If I press F5 to refresh the page, it redraws correctly refreshed.
So the question is, how do I refresh the page after downloading the file?
I have tried calling both Response.Redirect and Server.Transfer after BindGrid
For what it is worth, I am using IE7.

[Code]....
and this is the code behand fo btnSave onclick event:
[Code]....
and this is the code behand of btnPreviwe onclick event:
[Code]....
as you can see, when the btnSave is clicked, it is programmatically clikced the btnPrevew first, and btnPreview registers and fires the required JavaScript. But actually once the btnSave clicked, it does go to the btnPreview_OnClick event, but for some unknow reasons, the javascript in btnPreview_OnClick doesnt work, however, when i just put cstext2.Append("alert('hi')" instead of cstext2.Append("'SaveSignature()'", the javascript does executed, and also if i modifed the asp.net code for btnPreview to this, it works too.

I have an asp:DataGrid with templated columns. Here's one of those columns:
<asp:TemplateColumn>
<ItemTemplate>
<asp:LinkButton ID="btnDetails"
Runat="server"
CommandName="details"
Text="Details"
Font-Size="0.8em"
CommandArgument='a=<%# Eval("a")%>&b=<%# Eval("b")%>' />
<...>
When the command fires, the CommandArgument comes back unevaluated - it is the string a=<%# Eval("a")%>&b=<%# Eval("b")%>, not a=5&b=6 as I want. What's wrong with how I'm doing this?
I'm trying to find a hook / way to run some initial code to wire up a bunch of things before a service is called.
