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'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
{

Can I use VB and C# classes together in the same asp.net 3.5 project?

The problem is when I use Guid UserId = Guid.NewGuid ();.
In Table I UserId type: unique Therefore it does not work. If I use the UserId type: int working.

I've got a page with two ContentPlaceHolders. In first there is UpdatePanel with GridView. In second I located DropDownList which is trigger for UpdatePanel.
<asp:UpdatePanel ID="stanUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true" >
<ContentTemplate>
GridView & other stuff
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ATDropDownList"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
Running the page causes error: "Control with ID 'ATDropDownList" could not be found for the trigger in UpdatePanel". I thought it was because the ATDropDownList is located inside ContentPlaceHolder. So I changed ATDropDownList's ID to UniqueID as follow:
<asp:AsyncPostBackTrigger ControlID="ctl00$ContentPlaceHolder2$ATDropDownList" (...)>
Everything works good, but I want to change it from page's code-behind. I tried to put

somewhere in code, but without luck so far.

I have created my first Custom asp.net server control.But i think such projects probably contains AssemblyInfo file.But i am missing that. When i created project that file was not added.
I am working on VS 2008 Team System Edition,with VB.NET language.How to get that file ?
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 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

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 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.
