Does anyone know how to do this? I built a backend c# class in asp.net but want to access these same classes without recreating them in silverlight. Is this a possibility?
View 4 RepliesI have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()
Can I use VB and C# classes together in the same asp.net 3.5 project?
View 3 RepliesI've created a Gridview in my aspx page, which is referenced in two separate methods in the code-behind file. When I try to run the page, I'm getting a 'does not exist in the current context' error.After a bit of poking on the internet, it seems that I might need to declare the gridview at the class level if it's going to exist in more than one method... problem is, I do that and it disappears from the page altogether.I'm obviously not doing this right - I'm declaring it like this (abridged version):

I have a method I want to use on two gridviews which contain different information, ideally i want to do an if statement, something like

// do this
}
Trying to do basic webclient data pull in C#, and the methods are not available in visualstudio, and the code is not compiling.

byte[] resp = client.DownloadData(url);

Error 1 'System.Net.WebClient' does not contain a definition for 'DownloadData' and no extension method 'DownloadData' accepting a first argument of type 'System.Net.WebClient' could be found (are you missing a using directive or an assembly reference?) C:UsersMichaelDocumentsVisual Studio 2008Projectssearch2search2MainPage.xaml.cs'm doing this in a c# file for a XAML/Silverlight project, but can't imagine why that would make a difference. I can not find any reference to this issue on the web, and I had something similar to this working last month, but in a regular ASP.NET page, not in a Silverlight app.
I have a utility project that has an "XML" folder with two XML files in it, this project is then referenced by an ASP.net web project. I was wondering do you have to set some sort of build option to place the folder in the BIN of the website, or is there another approach to referencing these two files from the web project?
View 1 RepliesI'm developing a web site, and i'm using infragistics for web, but I want to use in some pages silverlight controls (Infragistics too). Is there a way to access a silverlight control's properties and methods from an aspx page?
View 3 RepliesI have a referencing problem in my project. I have an ASP.NET application where pages are in multiple subfolders. All pages user controls are working fine.
I just want to reference a page class that is not in the root folder (in subfolder from the root folder) in my usercontrol code-behind file like this
if (Page is ar_default){ //}Where ar_default is my page class name as it is in folder name "ar"The user control is also in the same subfolder as the page being accessed.Wnen I use the same method with pages in the root folder, there is no problem at all and it is working although I notice that the classes still not appearing in the coding drop down menu but if I typed the name correctly it work.like so:if (Page is _default){ //}When using the same code with classes in subfolders it is giving this error:The type or namespace name 'ar_default' could not be found (are you missing a using directive or an assembly reference?)I'm not using any namespaces also.

View 1 RepliesI have a silverlight application project that I need to add to an ASP.NET Project. I know it can be done because you can choose to have both when you first create a silverlight project, i'm just not sure how you would do it after the fact.
View 2 RepliesI've ran trough many websites and tried soo many things that I've finally decided to try it creating a question of my own. This is the error that I get when I try to access my WCF project from my Silverlight 4 app. anyone have any idea on how to fix this error? PS. If anyone needs any more information let me know.
An error occurred while trying to make a request to [URL] This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. see the inner exception for more details.
here is simple:
I have a windows project and a web project within the same solution. I want to share the classes from the Windows project with the Web project. I do that by adding them as a linked component.
The problem is that the classes calls forms, controls and other things that when in Web project makes error.
Is there a way to ignore that kind of error? I mean, I won't even use those functions on the project, they just work on the Windows one.

View 3 RepliesI have been working with ASP.net for a while now and was very familiar with how the page lifecycle worked. I am now trying to incorporate Silverlight into my ASP.net project and I am a little confused on how it works with the ASP page lifecycle.
For example, with Silverlight, I understand you need to access the server using the web service. I am able to populate a Silverlight datagrid by calling a stored proc through the web service in the loaded event. My problem is the DataGrid does not populate until ALL the code in the loaded event has executed. As you can see below, I want to do a simple calculation after I populate the DataGrid. I need to populate the DataGrid first and then do the calculation, but the calculation is done before the grid populates.
What I need to happen:
When I call 'tpService.getStepsAsync()', I need it to go to the web service to grab the data and then populate the DataGrid. Then I need 'a = 2 + 2' to execute. How can I get this to occur?

I have two projects: A web application project, that has a webpage that hosts a Silverlight application, as well as a web service A Silverlight application project, the one hosted in the above web application
If I debug the Silverlight application, it wants to run this with a generated web page, which will of course not start my web application, and web service calls fails due to some cross-site security model. So even if I have the web application running, the Silverlight application won't use it.
If I debug the Web application (that is, set it as a start project and hit Debug), then the Silverlight application is apparently correctly hosted, but I can't debug it. Any breakpoints in it shows up as those hollow circles.
So what am I doing wrong? How should I configure my projects so that I can start the web application, host my Silverlight application, and debug it?
I'm betting it is one of those "dough" moments when someone tells me, but I can't figure it out.
This is Visual Studio 2008, .NET 3.5 and Silverlight 3.
I've got a old working project. But i like to work in 2008 with it.
So i've made a new clean project.
And imported the code, also the .cs files with the classes, the thing, i could not add a ASP.Net Folder for the App_Code (strange?).
So i made it by hand, maybe thats the problem... ?
But if i try to run the project coud'nt find the classes, while they are there, in the App_Code folder.
I'm using VS 2010. I got the references to the classes from my project, now I need the .dll files but I can't seem to find them. How do you add the .dll's?
View 1 RepliesI would like to create a dot net page and combine in it some silverlight parts / elements...
how to do that?
I have existing ASP.NET 3.5 project I migrated to Visual Studio 2010. I didn't migrate it to .NET 4.0. Every time I try to edit .aspx page, it alters the .designer.cs class to point to System.Web.UI.WebControls.WebParts.UpdatePanel class instead of
System.Web.UI.UpdatePanel
class and then the build of course produces an error. The project properties says ".NET3.5".Also the "design" tab produces just one box saying "unknown server tag asp:UpdatePanel". It seems like it is looking at .NET4.0 to generate the desgn view, not 3.5
Is there a setting somewhere I need to change?

We have shared CSharp classes put into a shared folders for re-use. Now I want to add those classes into my project by creating a new folder:
1) Right click the solution,
Add -> New Folder
Give it a new, eg. SharedClasses
2) Right click the new folder "SharedClasses"
Add- > Existing Item...
Browse to the "Shared Folder", include those shared classes. But those files are added physically into the folder "SharedClasses" rather than a reference. How do I just add a link to those shared files? Since these files might be modified from time to time, I don't want to delete and add those file frequently.
I've build a Class Library, in the same project i put a web project. But its impossible to access the classes from the dll generated by the class library. Whats wrong? JumpTide XML uses the namespace like:
namespace JumpTideClassLib
{
public class jumptidexml
{
public class MetaTags

I just want to start coding a simple master detail form but through with loosely typed datasets/objects and also layer or tier architecture. Is there any starter project for this kind of code? Most of the help I find on google discusses strongly typed data objects or very advanced designs.
View 5 Repliesthere is already an asp.net web site developed,now due to certain requirements i want to use silverlight enabled pages in my project(for its flexible designing purpose).
View 2 RepliesI work in a suite of ASP.NET applications that have several different "modules". The applications all share a main menu, so they all link to one-another. The modules are the high-level areas of the application. So, for example, it might be Payments, Orders, Customers, Products, etc. And Payments and Orders are in one app and Products and Customers are in another. Some of these menu links are "deep links", for example it might be a link to a particular page within the Customers module, such as Create New Customer.
We are about to start a project that will add several more modules to this suite, probably as a new .NET application. I'm thinking about doing these new modules in Silverlight (for various reasons that are not material to the question). If I were to do that, I need to make the menu look the same as the menu in ASP.NET, as the users still need to feel like they are inside one "application".
How should I organize the Silverlight project(s) so that I can "deep link" from ASP.NET pages into particular modules in the Silverlight app? What is even the best idea for creating these different Silverlight "modules"? If I had something that would've been a page in ASP.NET (for example - Create Customer), should each one of those be a separate Silverlight app? Or should it be a separate User Control? Or something else? Should I reuse our shared ASP.NET menu, and deep link to different Silverlight "modules" even within the new application? Or should I reimplement the menu in Silverlight for navigation within the app? Are there menu controls for Silverlight that look similar to ASP.NET menus (with flyout submenus in this case)? Could I maybe even share a SiteMap XML file between them?
