- Getting control of Items within a DatalistI have a problem as I have placed a dropdownlist in a datalist.
Whenever the selected index changes I need to change a label inside
the datalist.
The problem is I can't get control of the label.
When dropdownlist changes it goes to a function with args of
systemEvent than a DataListItemEventArgs so I have no way getting
control of the item in the datalist to change the label.
Can someone please help me.

Lee, please narrow this down to a small reproducer and post the code here.
I don't know of any reason why there would be a duplicate web form. In fact,
I don't know what you mean when you say "duplicate web form".

- Capture hyperlink text propertyI have an aspx page (referred to here as page_1) with a datagrid whose first
column contains hyperlinks. When a user clicks one of these hyperlinks, he
will navigate to another aspx page (referred to here as page_2). I need to
cache the value of the link's text (hyperlink.text property) so that I can
use it in the page_load event of page_2.
I've thought of using a hidden field and then calling
Request.Form("hdnClickedLinkText") in the Page_Load event of page_2. What I
don't know is how to populate the hdnClickedLinkText field on page_1 when the
hyperlink is clicked. I've thought about using AddHandler but there is no
exposed click event for the hyperlink control. I could design a custom class
which inherits from the hyperlink class and implement my own Click event, but
this seems a bit much when a simpler solution may exist.
Does anyone have any other ideas?
TIA,

- not properly authenticating?hey all,
i have a simple asp.net app that using window authentication integration and
disallowing anonymous users.
well, when a user tries to browse to this page she gets a "The page cannot
be displayed error." I figured I'd at least get the asp.net error page.
any ideas?
some environment notes:
windows 2000 server sp4
windows 2003 r2 sql server 2005 sp4
xp pro sp2 vs2005 sp1 is my dev
xp pro sp2 is the user's machine with nothing but ie on it.
i'm thinking it's the user is not properly authenticating to active
directory because when i changed iis settings for the app to allow anonymous
the user can get to the page that way. but i'm not user how to troubleshoot
this if this is the case.
thanks,
rodchar

- TIP: httpRuntime executionTimeoutI had noticed a number of people posting that they where having
trouble getting the Web.config httpRuntime executionTimeout attribute
to work as expected.
I realized today that if the compilation debug attribute is set to
"true" in the configuration, then the framework doesn't seem to
timeout requests (probably because this might be annoying if you had a
debugger attached and were stepping through code).
It would be nice if the MSDN documentation for the executionTimeout
config attribute referenced this dependency. A similar thing that
threw me for awhile was that a trace="true" at the page level seems to
implicitly cause a No-Cache directive to be issued in the response.
Hope this helps someone.

- network (drive) access/impersonate identity problemI am experiencing difficulty access a mapped network drive in an ASP.NET
application.
While using the .Net framework v 1.1 implementation of
System.IO.Directory.Exists(), it fails to recognize a mapped network drive.
This is true if the path specified uses a mapped drive letter or is
expressed as a UNC address. I have also tried the drive letter and UNC
paths with and without trailing backslashes, respectively.
No luck with ASP.NET, but it does work when I create a simple C# console
test harness application. This indicates to me to be a security concern with
ASP.NET. Funny thing is - no exception is returned. For all combinations,
System.IO.Directory.Exists returns false. (If so, this behavior is very
inconsistent with the System.Security thrown for things like trying to write
to a file, execute code on another machine, etc.)
The following knowledge base article:
307901: INFO: Permissions to Connect to a Remote Access Database from
ASP.NET
http://support.microsoft.com/default.aspx?scid=kb;en-us;307901&Product=aspnet
recommends using impersonation, but an error occurs even before the 1st line
of my ASP.NET code is executed.
No windows event is logged either.
How do I get the ASP.NET worker process to recognize another machine's hard
drive, folders and files?
Any help is appreciated. Thanks!

- The request failed with HTTP status 502: Bad GatewayHi:
I have a running application built in VS2003 and using Net Framework
1.1. I recently upgraded to VS2005 and converted the project to use
2.0 Framework.
My call to the web service gives me "The request failed with HTTP
status 502: Bad Gateway".
Is there any special setting I need to do while calling a web service?
Any and All help will be appreciated.
Thanks,

- problem with multithreading and Web services method invocationHi:
I have an ASP.NET page which makes a synchronous Web services method
call. At the same time, however, I wanted it to load another page as an
iFrame (i've also tried as a javascript popup window) - this second
page is responsible for polling a DB and continually updating its text
box display.
The problem is that once the Web service call is initiated, the second
page becomes unresponsive exactly until the call is completed, when it
resumes. I'm baffled as to why this second page's request should have
anything to do with the first one's Web service request. I've tried to
encapsulate the time-consuming DB queries of the second page into a
separate thread and this works great (I tested it by printing a
timestamp to a file), but I also need a way of updating the display in
real-time while the Web services call is going through. Are there any
ideas as to how I can accomplish this?

- Oracle Data Provider for .NETHello to everybody,
I hope this group is the correct one for posting my problem. If I've
posted in the wrong place, could you please redirect me to the correct
group? Thank you in advance for that ;)
My problem:
I need to call an oracle function from a .NET application passing an
XmlType input parameter to it. I have no idea on how to set the value
of this input parameter. I've tried to pass a String, but it results
in a NULL XmlType parameter value (using Toad as a SQL Profiler).
Any help is welcome,
bye,
Simone.

- Understanding/explaining WebZones....The SDK has me a bit confused with respect to WebPartZones and the sections
within them. The SDK page for the WebZone has s table that lists the sections
within a zone: header/body/chrome/part controls/footer.
I get the header and footer sections, but the other three are a big hazy
to me... please correct these statements where appropirate (as I don't think
I have it just right). Two (part controls & chrome) of the items listed as
"sections" doesn't quite make sense to me as they seem to be more of categories/labels
than sections.
The body is essentially everything in the WebPart sans header and footer.
The Part Controls are essentially any controls added to the zone... correct?
The chrome is all the UI components/elements within the zone... correct?
If so, then why call chrome & part controls a section?

- Multi-threaded HTTP ModuleAll,
I am trying to write a multi-threaded HTTP module that handles the
OnBeginRequest and logs it. What I am trying to do is to offload the
logging to another thread which will allow the http module to release
the OnBeginRequest.
The issue that I have is that I keep on getting "Request is not
available in this context" exceptions.
The following is the code I am using:
using System;
using System.Web;
public class ProcessRequest
{
public HttpApplication HttpRequest;
public void ProcessingThread()
{
try
{
string sRequestUrl;
if (HttpRequest.Request!=null)
{
sRequestUrl=HttpRequest.Request.HttpMethod;
System.Diagnostics.Debug.WriteLine(sRequestUrl);
}
}
catch (System.Exception ex)
{
throw ex;
}
}
}
public class HttpRequestLogger : IHttpModule
{
protected System.Collections.Queue oHttpRequestQueue= new
System.Collections.Queue();
protected bool bModuleRunning =false;
public HttpRequestLogger()
{
}
// In the Init function, register for HttpApplication
// events by adding your handlers.
public void Init(HttpApplication application)
{
application.BeginRequest +=
(new EventHandler(this.Application_BeginRequest));
application.EndRequest +=
(new EventHandler(this.Application_EndRequest));
}
private void Application_BeginRequest(Object source, EventArgs e)
{
// Create HttpApplication and HttpContext objects to access
// request and response properties.
System.Threading.Thread oProcessingThread;
HttpApplication application = (HttpApplication)source;
ProcessRequest oRequestProcessor=new ProcessRequest();
oRequestProcessor.HttpRequest=application;
oProcessingThread =new System.Threading.Thread(new
System.Threading.ThreadStart(oRequestProcessor.ProcessingThread));
oProcessingThread.Start();
}
private void Application_EndRequest(Object source, EventArgs e)
{
// HttpApplication application = (HttpApplication)source;
// HttpContext context = application.Context;
}
public void Dispose()
{
}

- VS mangles HTMLOn one of our projects, using vs2005 professional, Visual Studio reformats
the html in an aspx page so that it is virtually impossible to work with -
although it still executes properly. For instance it takes well formed html
that is indented for readability and converts everything to uppercase and
removes all carriage returns.
it converts this...............
<table>
<tr>
<td> vAlign=top>
<asp:panel id="LEFTPANEL" runat="server" Width="400px">
<table... . . .
to this..........
<TABLE><TBODY><TR><TD vAlign=top><asp:Panel id="LEFTPANEL" runat="server"
Width="400px"><TABLE
The page is then full of errors saying that uppercase is not valid.
I don't recall this every happening before but it is happening on this
project. We don't know of any settings that have been changed.
TIA,
Gary

- Trying to show a Crystal Report at WebForm1.aspxTrying to show a Crystal Report at WebForm1.aspx:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
If Not Page.IsPostBack Then
showReport()
End If
End Sub
Private Sub showReport()
' Filling DataTable
'...
crReportDocument.SetDataSource(MyDataTable)
CrystalReportViewer1.ReportSource = crReportDocument
End Sub
Crystal Report shows on the web page very well. But if you click on
link page number 2, trying to get the next page, WebForm1.aspx will be
reloaded again, as page.ispostback. Then I can't see any more pages but
page1 of my Crystal Report. How could I show a Crystal Report, please?

- How to show more error message?I use these setting in Web.Config
<customErrors mode="On"
defaultRedirect="~/ErrorPage/GenericErrorPage.aspx">
<error statusCode="403" redirect="~/ErrorPage/NoAccess.aspx"/>
<error statusCode="404" redirect="~/ErrorPage/NotFound.aspx"/>
<error statusCode="500" redirect="~/ErrorPage/InternalError.aspx"/>
</customErrors>
The error of Code 403 and 404 is clear and it will transfer to a assigned
page.
But when the error StatusCode is 500 or not defined, I want to show
something more detail to user on the errorPage.
I have tried string sMsg = Server.GetLastError().Message in
InternalError.aspx and GenericErrorPage.aspx,
But the GetLastError() always return null.
How can I do?

- Can someone ExplainRun at server and Client javascriptsHi
i'm still getting my head around developing in a web environement.
I have a server button. on the load Page_Load event i use the following code
to register a client script.
btnReturn.Attributes.Add("onclick", "javascript:NewPatient()")
one thing i've noticed is that although the code fires it still seems to
come back to the server. (i had assumed that if their was only javascript
event it would only run at the client. But if there was both then it would
run first at the client and then the server)
I used a html button and in its onlick event it fired the same function but
did no do a postback to the server.
Can someone tell me a site that explains in numpty language what is going on
and how to create client side scripts/ assign them correctly.
Cheers

- TemplateColumn & BoundColumnA DataGrid can be changed to the editable mode by using a
TemplateColumn (say, with a Label in the ItemTemplate & a TextBox in
the EditItemTemplate) as well as by using a BoundColumn (which will
automatically change to a TextBox when the DataGrid is in the editable
mode).
So when should a TemplateColumn (with an ItemTemplate & an
EditItemTemplate) be used & when should a BoundColumn be used?

- shopping cart binding to datagridHi,
I'm wondering if there is a way to bind to datagrid or a gridview the
items in an arraylist. These items all have vars such as price,
qty..etc? (besides putting in a datagrid or datatable first).
ex.
ArrayList alShoppingCart = shoppingCart.GetCurrentItems;
alShoppingCart contains an array list of Item objects.
Thanks

- FormsAuthentication and Local Intranet ZoneI'm a bit stumped by this one: It seems that when I connect to my
application using the server's intranet name (http://intranetserver/MyApp/)
FormsAuthentication kicks back the user to the Login page after I call
RedirectFromLoginPage. It works fine if I access the server by IP address
(http://xx.xx.xx.xx) and if I access the server over its public domain name
(http://www.myserver.com).
Why is this happening?
I have IIS set to Anonymous Auth. Windows Auth is disabled. My web.config
auth section looks like this
<authentication mode="Forms">
<forms name=".MyAppAuth" loginUrl="Logon.aspx"/>
</authentication>
<authorization>
<deny users="?"/>
</authorization>

- How to save a TreeView?Hi Experts:
I'm using ASP.NET 2.0. I'm using a TreeView control with a design-time
configured XmlDataSource (an XML file). I use the TreeView control as a
"message board" with each node representing a message. I noticed that the
TreeView loads alright from the XML file but did not save anything. I call
the TreeView.Save() for each new node added into the TreeView. What I'm
missing here?
Thanks in advance!

- dynamic webservice creationHi all,
Is it possible in .Net 2.0 to host a Webservice without ISS? Yes, I've

creation and execution. Suggestions are welcome.
