I have written an ASPX page (with few server controls on it) and a WebService module. I am invoking this Webservice from client side using JavaScript.
I need to access these server controls (present on ASPX Page) in WebService when it is being executed at server and change/add properties(at server, not client side).
I am building 2 WCF projects. On is server side and the other is AJAX (you can see here the ultimate trouble you have to go through to make it work in another domain: URL....
As we may give the website to an outside developer group I want to be able to have a small log function that will go through server side (because i don't know if the dev's will jst put the user - pass in javascript if they have the option) and write a cookie with a 10 minutes enabled pass and everything else will be in Ajax - Javascript.
To do so I need to have WCF on both forms server WCF web.config and AJAX WCF web.config. (also note that Global_asax is taking place and it may interfere).Can it be blend in web.config somehow. Maybe breaking the web config in multiple pages?
I have one application in that there are two server
1. Application Server
2. Database Server.
I have install MSSqlserver 2008 on DB server , but i dont want to give report server URL as business dont want to expose IP of DB server. Hence i install Reporting services component on Web server. I configure Successfully to Database reportserver Database.
but when i clicked on report services URL it gives error: The report server installation is not initialized. (rsReportServerNotActivated) what extra needs to configure report server?? what are the steps to configure report server ?
I need to make an ajax call from my javascript and access a control on my page. Using a webmethod wont work then since it's static, do I have any other options?

I can load a generic user control just fine in my WCF service doing the following:
UserControl userControl= (UserControl) new Page().LoadControl("~/UserControls/MyControl.ascx");
However i can't seem to find any way to do this
MyControl myControl=(MyControl)userControl;
The reason i need to do this is because my user control has a custom property, person, I need to do the following:
myControl.Person=new Person();
essentially i need to simulate:
<%@ Reference Control="~/UserControls/MyControl.ascx" %>
which normally goes inside asp.net page or master-pages.any way of doing this in an Ajax Enabled WCF Service?

View 7 RepliesThe following 'hello world' webservice works fine on my computer (VS2008) but I can't get it to work on the server--either from an aspx page (below) or when invoked directly. I get '404 page not found' on the direct invocation.
[Code]....
I added the HttpGet and HttpPost to test the web service directly on the server. I can open the page and invoke it, but then get the 404 page not found response.
this has probably been discussed before but perhaps not enough as I haven't been able to find any literature on this method (parts are documented, but not as a whole I guess)Anyways, you start with a web service, and you call that web service client side with ASP.NET AJAX javascript. Once you get a reply, you can call a artial postback using __doPostback(a, b) and "a" is the control id of an updatepanel in your page and "b" can be an indicator for which web service you are using or your resulting data or both. Lastly you add a check for "a" and "b" like this:
[Code]....
Now you can execute any code behind function when you receive a response, and because it's async anything short of leaving the page and it will still postback when you get a response.For example, I have a site which display data from a database in a gridview and uses a client side web service to get the time last updated for a database, call the web service client side every second, then, when an update is detected, call a partial postback, alert the user, and update the gridview.Though this really is a hack, so I'm not sure if there any problems with this approach, if there's a simpler and better way to go about it (I'm all ears).
I want to access simple web service inside WCF service. How can i achieve it?
View 2 RepliesI want to Access remote server( ie., want to access online server not local server) in my Application.. I change Settings in SQL surface Area Configuration---> Remote Connection ( checked the Local and Remote Connection ) Then while running the application it showing the following error.(I make off the firewall also) An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

I have a Solution in which i m using Gridview which stores image inside it. Every time when user uploads images and clicked on button, image get inserted into Gridview.
But every time user hits on button page get postback,so to avoid this i used web method which is get called when user hits on button (html button). But when i m trying to bind gridview in this method.It is not get accessed .
how i access this gridview inside web method? Why Web methods are always static?Is there any other way to do this?
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?

I'm getting a strange data download from an Access database.Using Visual Web Developer 2010 Express, I created a web service that places records from an Access database in server cache and then reads the records, one at a time, from the cache. The data in the records is converted to a delimited string. The web service is called from an e-learning program called Toolbook that places Http Post calls to the web service. The web services uses vb and .Net Framework 2.0.
All works correctly with one exception. When a record in the Access db contains "&", it is downloaded to the Toolbook e-learning program as "&". If I place && in the record, I get "&&".If I download the data from the Access db using a classic.asp file rather than the web service, the "&" displays correctly.
