It helps quite a lot when you learn to use the debugger.
The exception is very obvious, you have not create a relationship. How does the framework know the data in a DataTable has any relationhip unless you tell it. Software development isn't magic.

Reading the documentation and understanding the tools you are working will help great deal.

Hi,
I having trouble with assigning dynamically checkbox's Checked value using values from a datatable.
Here's my code
<asp:checkbox runat="server" id="chk1" checked="<%# (DataBinder.Eval(Container.DataItem,"Enable")) %>">
How can i automatically convert the field Enable which is from datatable so it will be assigned as Checked's value?
That field's type is bool and values 0 or 1.
Many Thanks!

Checked='<%# IIF(ISDBNULL(Eval("dbFlg")),0,Eval("dbFlg")) %>'>

i made a Web Service project in visual studio 2008.
then added 2 "Web Service" files to the project.
Service1.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <system.web.script.services.scriptservice()> _
<system.web.services.webservice(namespace:="http://tempuri.org/")> _
<system.web.services.webservicebinding(conformsto:=WsiProfiles.BasicProfile1_1)> _
<toolboxitem(false)> _
Public Class Service1
Inherits System.Web.Services.WebService
<webmethod(true)> _
Public Function HelloWorld() As String
Session("foo") = "bar"
Return "Hello World"
End Function
End Class
Service2.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <system.web.script.services.scriptservice()> _
<system.web.services.webservice(namespace:="http://tempuri.org/")> _
<system.web.services.webservicebinding(conformsto:=WsiProfiles.BasicProfile1_1)> _
<toolboxitem(false)> _
Public Class Service2
Inherits System.Web.Services.WebService
<webmethod(true)> _
Public Function HelloWorld() As String
If Session("foo") <> "bar" Then
Throw New UnauthorizedAccessException
End If
Return "Hello World"
End Function
End Class
After i made a windows application, where i made a "Service Reference" to both web service classes/files.
The problem is that Service1.asmx doesn't share it's session with Service2.asmx,...
I get the thrown "UnauthorizedAccessException" on calling "Service2.HelloWorld()" because the session is not created in Service2.asmx after calling Service2...
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim bhp As New System.ServiceModel.BasicHttpBinding
bhp.AllowCookies = True
Dim x As New ServiceReference1.Service1SoapClient(bhp, New ServiceModel.EndpointAddress("http://localhost/ImsBrowserWebService/Service1.asmx"))
Dim y As New ServiceReference2.Service2SoapClient(bhp, New ServiceModel.EndpointAddress("http://localhost/ImsBrowserWebService/Service2.asmx"))
MsgBox(x.HelloWorld)
MsgBox(y.HelloWorld)
' Dim x As New localhost.Service1
' MsgBox(x.HelloWorld())
' Dim y As New localhost1.Service2
' MsgBox(y.HelloWorld())
End Sub
End Class
How to share the session between those files,... In Visual Studio 2003 it works fine when calling the service from javascript,... Now in visual studio 2008 with the soap client wizards it doesn't...
Any help would be welcome,
...
allowcookies="true"

Having problems with free PDF library sharpPDF and allowing it to write PDF file to child directory within ASP.NET application. The PDF is created just fine in my development environment but when deployed to production application (on same computer just separate folder) I receive the below exception.
I tried several different things such as:
- adding <trust level="Full"> to my web.config file for the application.
- verifying NTFS security settings on app directory. Added IIS_WPG with modify privileges. IIS_USRS had modify access already. As well NETWORK SERVICE has modify privileges.
Let me know any suggestions.

ASP.NET has it's own user-account, called ASP.NET[^]. Does that one have the appropriate rights?

Just tried that. Didn't notice that user account, but it doesn't work. Still receive exception.
|
|
|
|

My apologies, simply assumed that the account lacked read/write rights. You could try changing the trust level[^]

The error says "please contact your system administrator or change the application's trust level in the configuration file"
Did you do that?
|
|
|
|
|
Yes. I tried that with the below excerpt from my web.config file...The articles on this subject were very confusing, so I was hoping someone could shed light on if this is the proper direction for fix.
Regarding the below config file excerpt there were some articles that had a blank "originalurl" attribute. I tried that as well, and till same exception.
Could it be a trust level associated with the specific library?
<system.web>
<trust level="Full" originUrl="" />

Hi
I am showing some data from the database in the repeater like this.
<ItemTemplate>
<asp:Label ID = "lbl_CourseName" runat="server" Text='<%# Eval("Name") %>'/>
<asp:Label ID = "lbl_SectionID" runat="server" Text='<%# Eval("ID") %>' Visible="false"/>
</ItemTemplate>
So now what i want is when i click the Name, it should go to the "admin.ascx" page along with the corresponding ID. Any ideas ??

Hi Experts,
In my applicaition User will be receiving mail through the applicaiton to Outlook and Lotus Notes. Now the problem is the applications sents the mail with the formatted text to the plain mail or to the Lotus Notes.
Now my requirement is if it is sending to the Outlook then it must be a HTML and if it is sending to the Lotus Notes then it must be a plain text. Any idea is much appreciated.
|
|
|
|
|
And what if the Outlook user has set it to read email in plain text format? You cannot control how users will read their email, nor even determine what method they use to do so. You need to send your emails in multi-part form - an HTML part and a plain text part - and let the email client determine which to use. See here[^] for guidance.
