Hi, just wondering if there are any articles on MSDN on how to tackle 2 way data binding on complex objects aka composite objects? Seems to be a bit of a black hole in terms of documentation or at least my ability to find it. Cheers dan.
# re: ASP.NET 2.0 Tips, Tricks, Recipes and Gotchas

# re: ASP.NET 2.0 Tips, Tricks, Recipes and Gotchas
Tuesday, August 08, 2006 6:45 AM by Daniel
Hi Scott, Thanks for the quick reply. I have seen these articles and they all use typed data sets. I have a collection of complex objects that I am binding to. if I have Simple properties such as Person.Name then it works fine, no problems, however if I have a property that is an object and I try to access its properties, i.e Person.Address.Postcode then databinding fails. I have worked around this by handling the objectdataSource Updating event and adding the values into the object manually however I was wondering / hoping that there is a better solution for this? cheers dan.
# re: ASP.NET 2.0 Tips, Tricks, Recipes and Gotchas
Friday, August 11, 2006 2:52 AM by ScottGu
Hi Dan,
You can do 1 way evaluation of complex objects using the <%# Eval() %> syntax:
<%# Eval("Person.Address.Postcode") %>
Unfortunately two-way binding of sub-properties via the <%# Bind %> syntax isn't supported though. For these types of operations you'd want/need to use the event approach you mentioned above.
Hope this helps,
Scott

Hi scott, one problem i always face is the treeview state in a masterpage. It never keeps its state and the nodes get collapsed. Is there any article on how to keep the state?
# re: ASP.NET 2.0 Tips, Tricks, Recipes and Gotchas
Thursday, August 31, 2006 1:49 AM by ScottGu
Hi Chris,
One approach you could take would be to add a Page_Load event handler within the master-page, and use it in conjunction with the SiteMap API to expand the current node in the site that you are visiting.
Hope this helps,

Hi Scott. Your blog is a great asp.net resource and as i am new to asp.net, it has helped me in many ways. I have one question to ask, I have a master page that uses
some images and a css file that are placed in root\images folder. if i use deny users="?" in root web.config and go to login.aspx, the master page is loaded but without images or css styles. I have to place a web.config in the images folder with allow users="*" to make master page work correctly. Is my solution correct or is there something i have missed? or is there a better/recommended way to do it?
Shouldn't asp.net allow master pages to load resources from subfolders even with anonymous user?

I've succeeded in rewriting 404 requests from IIS back to their original url in ASP.NET, but IIS 5.1 doesn't allow post-backs to unmapped extensions.
Does IIS6 allow the POST verb to unmapped extensions?
How bad is the performance hit when IIS is configured to send * to the runtime?
Thanks,

# URL Rewriting
Thursday, January 25, 2007 9:21 AM by Nathanael Jones
I just read that ASP.NET 2.0 is now capable of sending requests back to IIS for proccessing, so mapping * to aspnet_isapi.dll doesn't invoke a performance hit.
I originally read something (probably regarding 1.1), that stated how deadly it was to map * to aspnet_isapi.dll, due to performance issues.
Is this correct? I've tried to do URL mapping in various ways without this, and failed miserably. I have tried leveraging the 404 rewrite in IIS, using a mixed rewrite/redirection system, and many other less successful approaches.
Thansk,
Nathanael
# re: ASP.NET 2.0 Tips, Tricks, Recipes and Gotchas
Tuesday, January 30, 2007 12:36 AM by ScottGu
Hi Nathanael,
You can now enable * mapping much more efficiently using IIS6. For static files (like .htm and .asp), ASP.NET will then call back into IIS to have it process them.
Can you send me an email regarding url rewriting? I can then loop you in with someone to help.
Thanks,
Scott

I found a solution to my most pressing issues. You can view it here (I will try to post it below, but I don't know if it will take. My last one didn't).
http://nathanael.jones.googlepages.com/resolution
The last three questions are still relevant, if less important. Due to the lack of documentation, and 'black-box' nature of ASP.NET, I'm not too confident about these.
Thanks,
Nathanael
What do you use for URL and path manipulation? I know the runtime uses System.Web.VirtualPath and System.Web.Util.UrlPath, but they are marked ‘internal’. I’ve had to create my own class to maintain URL-parsing consistency.
Is there a reason why ASP.NET uses redirection instead of URL rewriting for error pages? I personally find it much easier to deal with errors and 404s if the URL doesn’t change on me. I hate it when I misspell one character, and the server redirects me to a new URL, denying me the chance to rectify my mistake. I have implemented a custom system in global.asax that uses Server.Transfer to handle error messages; the admin is given a page with descriptive exception details, while all the other unauthenticated users are provided with a generic message. Is this an acceptable approach?
Is it fine to ignore the url authorization system and simply use User.IsInRole throughout my code? Many of my pages do not have very clear-cut security requirements, and must perform complex role checks.
# re: ASP.NET 2.0 Tips, Tricks, Recipes and Gotchas
Tuesday, January 30, 2007 1:49 PM by Nathanael Jones
Ok, I have another problem...
I am caching ASP.NET snippets in the database for the summary field on each article.
As the paths in each snippet are relative to the parent article file, I have been creating an instance of Page and using the ParseControl method. Unfortunately, this seems to simply bring back a LiteralControl instead of the proper hierarchy.
What do you reccomend?
# re: ASP.NET 2.0 Tips, Tricks, Recipes and Gotchas
Wednesday, January 31, 2007 8:36 AM by Nathanael Jones
Addendum: I mean AppRelativeTemplateSourceDirectory, not TemplateSourceDirectory. Also, this property must be set recursively. See example below.
========================
///
/// Recursively sets the AppRelativeTemplateSourceDirectory property on the specified control and all of its children
///
///
///
public static void SetPathRecursive(Control c, string AppRelativeTemplateSourceDirectory) {
if (c == null) return;
c.AppRelativeTemplateSourceDirectory = AppRelativeTemplateSourceDirectory;
foreach (Control child in c.Controls) {
SetPathRecursive(child, AppRelativeTemplateSourceDirectory);
}
}
///
/// Renders the specified code to the specified output stream
///
/// The code to render
///
/// The parent page
/// The path the specified code should be virtually executed from. The location relative paths are resolved from
public static void RenderCode(string code, TextWriter output, Page parent, string AppRelativeTemplateSourceDirectory) {
//Parse the text into a control object (a container control object is created automatically.
Control c = parent.ParseControl(code);
SetPathRecursive(c, AppRelativeTemplateSourceDirectory);
//Render to the control
XhtmlTextWriter htw = new XhtmlTextWriter(output);
c.RenderControl(htw);
}
# Update
Tuesday, February 06, 2007 1:33 PM by Nathanael Jones
The ContentPlaceHolder patch described on http://nathanael.jones.googlepages.com/resolution isn't working properly... All of the paths are rendered by HtmlLink as if the control is located in the application root. If I set the AppRelativeTemplateSourceDirectory to "~/content/downloads/articlefolder", I get worse issues. The path resolves twice, as in "content/downloads/articlefolder/content/downloads/articlefolder/stylesheet.css" Wacky. This is when good documentation is really missed....
What do I try next? Control adapters?
Please help.
Thanks,

# The Infamous HtmlLink
Tuesday, February 06, 2007 3:02 PM by Nathanael Jones
Apparently there wasn't any problem with the code I posted... A little quirk with the HtmlLink control was tripping me up.
In a few master pages I used the Control.RenderControl method on all children of the ContentPlaceHolder object inside the HEAD.
This was used to pull out information from the meta tags and display the posted date. This had the side effect of triggering a RenderControl on my HtmlLink controls before render-time.
See ContentPlaceHolder patch, http://nathanael.jones.googlepages.com/resolution)
HtmlLink renders correctly the first time the function is called, but starts duplicating and corrupting the href element on subsequent calls. Yet another GOTCHA for the list.
Truly, this project has been agonizing like no other. Reverse engineering device drivers is lots of fun in comparison.
# offline client
Monday, February 26, 2007 4:50 AM by Yenkay

I am developing an e-magazine in asp.net 2.0 and SQL server. I want to develop an Offline Client to view the magazine offline. Any ideas about creating an Offline Client application for ASP.Net application with DB Operation.
Thanks in Advance

Hi Yenkay,
Developing an offline application using ASP.NET is pretty hard (since it needs to be connected to a web-server).
I'd probably recommend building a Windows Forms or WPF client application instead. This will enable you to work disconnected from a web-server.
Hope this helps,
Scott

Scott,
Do you have any links to information on the process of developing an ASP.NET web application using Team Foundation Server? If not, I'd love to see some posts from you along those lines or some howto videos/articles on the subject.
Interested in having my small team of developers (3) able to checkout files, update them, test/debug their changes to the site locally on the machine and then when they check in the files, only then would the changes be reflected on the development IIS server.
Thanks in advance for any help/links you can provide.
-Tom

Hi Tom,
I don't know of some off the top of my head, but Brian Harry has a great blog here and might be able to help: http://blogs.msdn.com/bharry
He runs the TFS team and blogs a lot about it.
Thanks,
Scott

On Aug 8 there was a post that stated, "I have worked around this by handling the objectdataSource Updating event and adding the values into the object manually..." Can you show an example of how to get at the object that is created?
For example, I have the below and before that update method is called I need to set a property on that Employee object that is passed to Update.
.aspx
dataobjecttypename="mynamespace.Employee"
updatemethod="Update"
.aspx.cs
protected void objectsource_Updating(object sender, ObjectDataSourceMethodEventArgs e)
{
...
}
Employee.cs
[DataObjectMethod(DataObjectMethodType.Update, true)]
public static bool Update(Employee o)
{
o.Save();
return true;
}

Hi Shawn,
I believe you can add the values using the "e" parameter to the updating event above. I believe there is a Params collection there where you can add any custom values you want.
Hope this helps,
Scott
