I figured it out...Thanks for the info. for anyone else trying this, just add the controls to your toolbox via their online instructions, then you just need an asp:scriptmanager with a

after it containing all of the ajax controls.

Aspx Page Call issue

hi frnds,

i am stuck by problem of calling aspx by another aspx and these two aspx pages are in different asp.net web applications.

If i include two asp.net web application projects in solution explorer, is it possible to call aspx page of one application from aspx page of another application.

And if it is not possible the alternative which occur in my mind is that making different project for each application and deploy each project seperatly in IIS then calling aspx to aspx but still dont know is it possible.

Plz anyone suggest me the fine solution to this problem.

Thanks a lot !

Thanks & Regards

assuming you dont want to pass any kind of session info between the pages...you can use Response.Redirect(address);

since they are different projects i assume they will run under different domains, so session info wont transfer..and since they're different pages viewstate wont either. if you have to pass information between them, the only way i can think of is to either put the information into the query string and go to a "hide" page which puts it back in the session and redirects to the page you want(small security hole there..well not really small) or the better way is to put the info into a temp table in the database with a random pointless temp id that is generated each time, an dpassed to the new page in a query string, which th enew page uses to lookup the info and then delete it from the database, once its been read into memory..thereby preventing anyone from breaking in because the table will have random id's and will never have much data in it...once you're able to see the ID its already been deleted. if you want to hide the query string, you can either use a frameset when you first go to the page, or use a "hide" site to quickly move it to the session then go to the new page.

hi

Thanks for ur concern but right now i dont want to pass anything in between ....................u said response.redirect(address)

but the question is if the applications installed on the server which has the ip say for example :- 123.12.3.23 and application folder name dialgmr in wwwroot of IIS then it will be

Response.Redirect("123.12.3.23/dialgmr/default.aspx);

Is that ur mean and this will not run on asp.net server localhost
Plz Give some example if possible

Thanks a lot !

ok say i have 2 web apps... a main app and a app that lets me process credit card info..you get to the main app by going to www.jimbob.com(i dontknow if thats a real address or not), and the payment app is in a subdomain payment.jimbob.com so that i can use it from other apps when i build them. make sense so far? good, now i have a button somewhere in the mainapp that takes you to the payment piece to buy something, so in the button click i'd insert data to the db(i do need to pass things between sites) and do a Response.Redirect("http://payment.jimbob.com/payment.aspx?tempId=35hgs"); now that obvisouly wont work in my dev environment because the dns records for jimbob and payment.jimbob poitn to my production webserver. so i put an entry into the <appsettings> section of my web.config file for the main app project that looks like, <add key="paymentPath" value="http://payment.jimbob.com/payment.aspx"> so with one change i make the apps work in dev or prod(i also have one for the connection string to th db so i can switch between dev and productio ndatabases easily. with the web.config entry my button code changes to

Response.redirect(ConfigurationSettings.AppSettings["paymentPath"] + "?tempId=35hgs");

i have used this method but have not tried the code snippets here, i may and probably do have typo's,sorry. if you're in dev and your dev machine is hosting everything, you can use http://localhost/whatever but you do have to have the http part if your leaving th ecurrent project/domain(changed from www.blah to payment.blah counts as changed domains espically if you are using ssl to secure things(i recommend that) and session info wont transfer..it also wont transfer between secure and non secure as the session is encrypted comeing out of secure, and its expceted to be encryped going into it..i may be wrong with the newwer versions out now, but i remmebber having that problem a couple years ago. If however you want to simply change directories or pages in the same projet you can use relative paths ../newdir/newpage.aspx or if everything is in the same dir you can use "newpage.aspx"

hope this is more helpful. if you want the exact code or more code than i've given you i recomend asking someone else, or reading the msdn pages about Response.Redirect or some of the articles here i know deal with it. for something more complicated i may post full or more code, but i hate posting full code for people because the vast majority just copy it and never learn how it works and its mine/our fault when it breaks.

Missing Parameters in call to WebService

I have a trivial webservice set up that takes a single parameter and returns a number of items according to the value of the parameter:

[WebMethod( Description="Returns the top 'count' latest articles.")]
public XmlDataDocument GetLatestArticles( int count )
{
	if (count < 1)
		count = 1;
	if (count > 100)
		count = 100;
	return ArticleCache.GetLatest( count );
}

I have some simple parameter checking, such that the method will always return at least one article and at most, 100 articles.

However, if the client does not provide the count parameter at all, a System.ArgumentException is thrown before the webmethod is called and an ugly error is returned to the client. I would like to be able to catch this exception and supply a 'default' value to the inner method call, so that the client continues to function.

I tried making the count parameter nullable, but then the default WsdlHelpGenerator.aspx doesn't display it, because "The test form is only available for methods with primitive types as parameters." This makes it rather difficult to test - especially as the services are for consumption by a third party developer.

Is there any (elegant and easy) way of catching the exception and handling it gracefully?

Thanks.

Can't load WebControl from subfolder

31-Jul-08 8:24

depending on how you have things set up..i wrote an xml file and from there had a wsdl and server stubs generated, but in the XML i'm pretty sure that you can make the parameter optional, then look for it in the server and give it a default value if it s not there. or you might be able to set a default value in the XML...since you typically need a wsdl and the xml file(maybe) to generate a client app, it should work for everyone. i believe setting the minoccurs attribute to 0 in the xml file makes it optional, but i have not tried it.

Hi there,

I've craeted a new WebControl in my controls subfolder of my project named myWebControl. VS2005 now created a public partial class controls_myWebControl which derives from System.Web.UI.UserControl. My myWebControl has some Properties, The trouble I have is to load this control in Webpages (project folder) calling
<code>controls_myWebControl myCtrl = (controls_myWebControl)Page.LoadControl(path to myWebControl);</code>
I can only create an instance of WebControl but now I can't use my properties. Any advice? Thanx in advance!!!

Hi,

Just check whether you have set accessors also defined for the properties in your user control.
And also just check whether the access modifier of the field is private and the property is public.

As i see there is no problem the way you have done it..

Hope it helps
Thx,

Web.Config vs. Machine.Config

Our shop is just starting to write ASP.Net applications. We're trying to think ahead and write our applications with easy maintenance in the design.

We'd like to put some of our connection strings that will be used by multiple web applications in one area. We were thinking about the machine.config file but we're not sure if this is as secure at the web.config is supposed to be or not?

Any suggestions? Confused | :confused:

Hi there,

I'm currently trying to fix a bug in a site that uses a gridview to load info from a database via a few dataviews into several tabs in a tab control.

Part of this information is the latitude and longitude which is used to display a map on virtual earth. I am having a problem in that the javascript GetMap() is called by adding an onload command to a body I have nested in the fourth tab.

This means that the javascript is only getting called once as I'm using an update panel to remove full postback.

I'm calling the javascript from the dataview databinding sub on the server side to prevent the map from being loaded too early without the necessarry information.

How can I call the javascript eveytime the index is changed on my gridview??

You can see the problem on http://www.ozfarmguide.com/Farms.aspx[^]

Many Thanks

No you are not. Server side code cannot call/execute client side code.

JimBob SquarePants wrote:

As I stated above you can't. What one can do is take advantage of whatever client side mechanism they are using, like body.onload event, to execute javascript code. In your case since you are using an Ajax call (update panel) then you need to use whatever mechanism it supplies to execute client code upon return of the request to the browser.

Yeah sorry, call was probably not the best choice of words.

I tried adding OnLoad="GetMap()" to the markup on my UpdatePanel but I returned this compilation error: 'GetMap' is not a member of 'ASP.farms_aspx'The client side attributes are not available in the code behind unlike the body.

Javascript is a great unknown to me. I had real trouble getting the map to show properly in the first place.

What's your advice?

My general advice is not to work with technology that is unknown to you without first learning it. As to your current problem, I have never worked with the update panel but I imagine there must be a client side mechanism to leverage upon return to the browser. I would also imagine there is some small amount of example code in the MSDN documentation for the update panel control. I would certainly start by looking there. If that is not enough I would goolge for something like: ASP.NET UpdatePanel tutorial
