I have a sql stored procedure that runs for about 3 minutes, I am looking to execute this stored procedure from asp.net, but I know that if I do, that asp.net will most likely time out.
I'm thinking of just creating a job within sql to have it execute that stored procedure, and have asp.net call a stored procedure to call that job. I have a table that is updated when the stored procedure starts, and when it ends.
My application will use this to determine when the script has finished, however, I wanted to know if there is another way to run the stored procedure and not have it wait for it to finish to push a response back.
I just want to know if there is a more efficient way to do this, or if I should just stick to creating jobs for scripts that take forever to run.
What I'm trying to do is fill in a questionnaire, and have the option to not complete it then it automatically saves, once clicked on "Save" button. However, what I want to search for is previously non-completed questionairres.
Would I have a "status" field in the questionairre table to trigger either "completed"/ "non-completed" when the "Save" button is clicked (in the event of non completed questionaires? How is this normally done?? Im sure there are a hundred and one different ways to do it!

How can i display a loading gif image before completion of the code behind code.
ps: if you can post some real code examples, not just concepts and how to do... i've tried many things so far without success, including pre-loading images using javascript and MS AJAX toolkit stuff.
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.
View 5 RepliesI 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 .
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
database before the user resubmits. So I want to run some code when the error fires, how can i do this?

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:

Detecting Page load Completion? How could we do this using jscript or jquery, would it be possible? Kindly give your views and ideas. I have an asp.net web page, which is huge and takes time to load. If the user clicks on any buttons on the page, before the page completes it's load, we get error messages. Since some of the hidden field values in the page, have value=0 because the page did not complete it's load. I hope I was clear with my question. Meanwhile I need to work on improving my code to process quick.
I do have an update panel, on my page.
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.

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.

View 2 RepliesI have a button where I use an Animation Extender. When I click the button I have to set OnClientClick="return false;" otherwise the Animation Extender closes.
So that causes my problem. How do I execute server side code from this button?
I have tried this code in my code behind, but there is an error:
Code:
Dim strScript As String
strScript = "<script>"
strScript = strScript & "return false;"
strScript = strScript & "</script>"
ScriptManager.RegisterStartupScript(Me, GetType(Page), "MyScript", strScript, False)
This is my code for the Animation Extender:
