I'm trying to check if the component already has the event...In my example here, I would like to know if the CollapsiblePanel already has the expandComplete handler before I add the event
[Code]....
I am writing a quick-and-dirty in-house ASP.NET application that needs to be able to run a task after a specific period of time. If it was a proper application, I'd probably use a windows service but I don't really want to bother with the extra complexity of that.I could put code in the BeginRequest handler to check whether any such tasks are due, but of course nothing would happen if nobody is using the application.at the moment the best option I can think of is something like ShellExecute("nohup sleep 1000; wget http://server/dummypage.aspx") (if you'll excuse the mixed windows/unix nomenclature).
View 2 RepliesI am trying to stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.
I would like to know how can I list for every page (child page) selected the number and id of localize component in the current page. I need this to update resources files, a button will be on the master page and when they click on it, they will go to a page which show up every data in the resource file.
View 1 RepliesRather strange behavior.I have a web application, which has a aspx page which comrises of master page, user controls, ajax tab control & infragistics grid.This page is opening fine from many clients But this page is not opening on one specific client browser and gives sys.invalidoperationexception: ctl00_ContentPlaceHolder1_tc1 component was not found., with XP & IE 6. Please note that, other client browsers with this configuration in the past never gave this problem. This is the first time in many months I have observed this error.I tried to look for various IE options as well, if it has something to do with scripting setting being enabled/disabled, but could not zero-in on anything specific.Has anyone seen this before and can help me in this regard. Any heads-up on this will be really helpful.

new to working with ajax and having a issue with the Editor component.I have a large internal website to my company and I have a page that I have added the editor control.I also have a button on the same page. In the Button click event I want to do something with the text from the editor control, like save to SQL.But it says Editor1 is not declared, and it is not intellisense anywhere.I have played with this for two days and not any closer to making it work.

I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.
View 1 RepliesI am wondering how to add a javascript event handler using asp.net ajax. I need to add event handlers after ajax update because Jquery plugin to sort tables doesn't work and the onload method to display a screen keyboard does not trigger as well. Is there a way to do that? Maybe I need to switch to some other ajax library or/and try Asp.Net MVC to accomplish?
View 1 RepliesI'm sending values to Generic Handler via Ajax like that way.
xmlHttpReq.open("GET", "AddMessage.ashx?" + (new Date().getTime()) +"&Message=" + Message,true);

I need to run a SELECT box [on]change handler after changing the selectedIndex.
I see the selectBox._events['change'][0].handler() method added by $addHandler, but what is the ASP.NET Ajax way to raise it as an event?
The backup plan is to set sel.onchange directly and skip ASP.NET Ajax events completely.
I've inherited some code that is having a serious problem. On one page, there are several pairs of "Yes"/"No" checkboxes that act like pairs of radio buttons through the use of the ACT MutuallyExclusiveCheckBoxExtender control. They work as expected. However, when I navigate away from the page, I get a "Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method." error in the dynamically-generated ScriptResource.ax...c2d9970 [dynamic] file.
The specific method in the dynamically-generated code is:
var $removeHandler = Sys.UI.DomEvent.removeHandler = function Sys$UI$DomEvent$removeHandler(element, eventName, handler)
The element is set to any of the checkbox controls (I've removed them one-by-one and it happens to ALLof them) and the eventName is "Click". I gather from the code that it's trying to do a removeHandler before the addHandler for the particular element has taken place. True, I don't have any explicit addHandler lines in my code, but I don't any explicit removeHandler lines either. About all I've got in the aspx code is:
[Code] ....
The formatting of the code in this message is a bit weird, but it's basically a simple table with three columns. On each row, there's text in the first column, the checkboxes in the second column and a button in the third. I've searched high and low on the web and nearly every thread I read about his error talks about it in relationship to the use of command buttons in an ACT UpdatePanel.
I have a complex page. Basically, it is a ListView with images displayed through handlers. Paging is done through a datapager. This is all wrapped in an Ajax UpdatePanel so it pages seamlessly.
When the user sees a image they like and click on it, it should display in an image above the ListView. This work when I DON'T use the updatePanel, but of course, then I get flicker. Wrapping it in an update panel results in the paging working. When the user clicks an image it goes to the db as expected, but it simply never updates the image being displayed.
Here is how the image that is clicked on is defined.
<asp:ImageButton ID="imgbtnImage" runat="server" ImageUrl='<%#"~HandlersThumbnailDBHandler.ashx?id=" & Eval("ID")%>' CommandArgument='<%#Eval("ID")%>'/>

Just looking for a bit of advice really my colleage suggested using a http handler .ashx file to handle the ajax calls that I will be getting on a web app via a jquery plug in on the page.What i have previously done is write a page _ControlName.aspx which looks at the url an takes or supplies what it needs in json format.What is the better way to handle ajax?

foreach (Control cPagerControls in Pager1.Controls)

View 1 RepliesI have a grid view in Ajax UpdatePanel. In a column of a grid view I have a button call btnAddNewRecord. I need to fire btnAddNewRecord.Click event once I click on that.
How can I do this?
Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?
