Cannot Refresh The Page After Calling Server Side Code Using Javascript

Apr 4, 2011

I am using Ajax's EnablePageMethods way to call server side code using javascript. The problem is that in IE8 the page automatically refreshes after the ajax call has been completed i.e. the server side function has been executed successfully. I want the same to happen with Chrome and Firefox but it doesnt refresh the page once the server side function has been executed.

I am using this way to call server side code from Javascript -- [URL]

this is the javascript function:

[code]...

this is where i am calling the javascript event:

<a href='myPageName.aspx' onclick='javascript:editNode(1);return false;'>Delete</a>

Using Ajax Script To Load Content From An Aspx Page On Another Server Than The Page Calling The Content

Mar 22, 2010

I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.

I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.

Javascript - Jquery.ajax Set With Async=true To Send Data Back To Server Not Working If Page Redirects/reloads.

Sep 3, 2010

I'm trying to save some content whenever a button/hyperlink is clicked using jquery.ajax (Using Asp.net 3.5). The logic is as follows:

Through .bind in jquery I bind my own method(MakeLog) to a button click or hyperlink click. The click events of button/hyperlink contain nothing, I need to use .bind for selective controls.Now we have a button whose click event will fire a method, say MakeLog.Code snippet for MakeLog is as follows:

var xhr = jQuery.ajax({
url: "/Logger.aspx",
data: { content: logContent }, [code]....

This works fine in IE but in Firefox this is not sending the data back as expected.I tried to identify the issue and came across the following: http://stackoverflow.com/questions/3522944/jquery-ajax-calls-async-false-vs-async-true .What I understand is that, whenver page is redirecting/reloading due to button click or hyperlink click the async call is not working properly.

DataSource Controls :: How To Configure To Allow Windows Services Running On The Web Server To Access Sql Server

Jan 14, 2010

We have a cient we are stting up that has 2 separate physical servers, one that is the web server the other the database server. Using impersonation we have been able to get the website to connect and retrieve data from the sql server so that part is not an issue. The problem is I have a windows service application that must be installed on the web server (as it process files downloaded to an ftp site) and it must be able to connect and write to the sql server as well.We tried adding a system.web block with the impersonation stuff to the app.config file which of course did not work. Can anyone tell me what/how we need to configure this properly?

WCF / ASMX :: Calling A Web Service On A Remote Server From A ASPX Page (website Project VS2005)?

Aug 30, 2010

I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder. When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.

The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for the new web service i'm trying to call. Have I missed any steps?

C# - Validating Textbox Content On Blur By Calling Server - Side Method Without Affecting Page Behaviour

Oct 21, 2010

I have a textbox in one grid-view column where upon entering a particular value and losing focus of the textbox, should post to the server to get the text validated through a server-side method. If the entry is valid, a result set to fill rest of row cells would be returned, else the bgcolor of the textbox needs to be changed to Red.

I tried posting back through the obvious way, i.e. making the textbox's autopostback as true and wiring up a server-side OnTextChanged event handler to validate the entered value.

It is working with this setup, but is also affecting the remaining page controls behaviour. For example, if I click a button in some other grid after entering some text in the textbox, the OnTextChanged handler gets called thus preventing the button's click event, which I also wish to call to execute its functionality.

"access Denied" When Access Server's COM Port Through Javascript

Aug 29, 2010

I've written a Generic Handler so I can access my server's COM port through javascript. I'm doing this, because I'm writing a Web Interface to an ESP-88 from BOSE, for internal use. The code must be configurable, and I added routines for both TCP/IP support and RS232. In a desktop app, the code runs fine, but in an ASP.net 4.0 App, the code crashes with the error "Access to the port 'COM2' is denied.". TCP/IP connections work, but serial is also required for us.
