I have a Web Site project in VS2008, C#, .NET 3.5 and the Access to the Code-Behind has lost it's functionalilty.
i.e. I have a Button on a page... dbl-clk on button should take me to the Click Event of the button. It does nothing?
I tried exporting the Tools|Import Export Settings and re-setting them to the Default for Web Site... still no change...
I'm kinda new to web services and want to make sure I am doing things correctly.
I have a custom object which has sub objects as well. (let's say Company object, sub object is collection of Employee objects)
I want the web service to return a collection of Company objects. Do I make the service return a Dataset and custom generate a dataset with datatables representing the different objects?
What is the best way to do this? I tried to just serialize it, but that doesn't seem to work either.
I tried this dll
[URL]
But the output XML doesn't seem to include the sub object.
I created a simple gridview user control with a custom property ProfileType which should load different records depending on the ProfileType value when attaching to a web page.
This is my web page:
[code]....
how I can expose user control custom property at its code-behind file.
When i run the following code it the error as :
""Object reference not set to an instance of an object.""
Protected Sub CreateUserWizard1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles CreateUserWizard1.Load
Dim SQLData As New System.Data.SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True")
Dim cmdSelect As New System.Data.SqlClient.SqlCommand("SELECT TOP 1 EmployeeId FROM a1_admins Order by Id DESC", SQLData)
Dim label11 As Label = CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("Label11")
SQLData.Open()
Dim dtrReader As System.Data.SqlClient.SqlDataReader = cmdSelect.ExecuteReader()
If dtrReader.HasRows Then
While dtrReader.Read()
label11.Text = dtrReader("EmployeeId")
End While
End If
dtrReader.Close()
SQLData.Close()
End Sub
End Class
Is it possible to expose server control as properties? See below.

View 3 RepliesWe've got some WCF services we're hosting via IIS. The application in general uses Forms Authentication, and we'd like to continue making that available for web service clients. We just have a <authorization><deny users="?"> in our web.config and some authentication/redirection goodness that gets everything done.
The problem is we'd like for users to be able to access the metadata for the services without authentication. Can they visit /services/v1/ArtifactService.svc?wsdl anonymously and yet still require authentication for /services/v1/ArtifactService.svc/rest/GetArtifacts?studyId=123? If so, I can't figure out the right incantation in the configuration.
The best I can think of is to set an absolute URL in the metadata service behavior, but then I have to doctor the path on install anywhere we deploy. (<serviceMetadata httpGetEnabled="true" httpGetUrl=[URL]
I keep getting this error Object reference not set to an instance of an object. What i want to do is when the button is clicked my panel is visible with a textbox of the id number, of the row that they clicked. by id number i mean the column id, and the number given to it by the database.

Dim button As Button = CType(e.Row.FindControl("button1"), Button)
Dim id As Label = CType(e.Row.FindControl("id"), Label)
button.OnClientClick = _
Panel1.Visible = True
Label2.Visible = True
Label2.Text = id.Text

I'm trying to expose a webHttpBinding EndPoint using Framework 4.0.
<endpoint address="web" binding="webHttpBinding" contract="MyContract"/>
However, when browsing using WFC Test Client, I see nothing. If I change my Framework target to 3.5, it works fine.
Is there something different in 4.0 to get this to work?
I am creating a web application that allows a user to download a csv file of a gridview. However, after looking at tutorials online such as http://www.aspsnippets.com/Articles/Export-GridView-To-Word-Excel-PDF-CSV-Formats-in-ASP.Net.aspxand such, I successfully got the table I wanted but there are HTML content appended to the table as well.There was also a similar problem being brought up on the forum,http://forums.asp.net/p/1528174/3692826.aspx. The solutions didn't help me much though. However, I am not really sure how Handlers can benefit this. Furthermore, I don't want the user to be navigated to a blank page just to download the csv file. I tried to debug and insert removal code to remove the html code before the response object is being wrote out but seems even at the end of the writing method, the response object seems to be holding just the table content only.
View 4 RepliesI have a base class with several derived classes. I want all of my derived classes to have the same Public Shared (static) method with their own implementation. How do I do this?
View 3 RepliesI am using a custom membership provider. I want to expose additional properties under User class.
So in my custom membership provider class I added few Properties (FirstName, LastName, Address, etc) and set their value in ValidateUser(). However back in aspx.cs if I type User. I do not see FirstName, LastName and Address in intellisense.
Is what I'm attempting to do even possible? Or do I need to resort to using my own custom user class? In which case I wouldn't need to use custom membership provider because I can program my custom user class to do everything that custom membership provider can do. Only thing is I would need to pass this user object in session object.
I have a user control with a panel on it:
CustomControl.ascx
<%@ Control Language="vb" CodeBehind="CustomControl.ascx.vb" %>
<asp:Panel ID="myPanel" runat="server"></asp:Panel>
I'd lke to expose that panel as a property that I can use at design time.
CustomControl.ascx.vb
<ParseChildren(True), PersistChildren(False)> _
Partial Public Class CustomControl
Inherits System.Web.UI.UserControl
#Region "Members and Properties"
<PersistenceMode(PersistenceMode.InnerProperty)> _
Public Property SomePanel() As Panel
Get
Return myPanel
End Get
Set(ByVal value As Panel)
myPanel= value
End Set
End Property
#End Region
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Response.Write(myPanel.HasControls.ToString())
End Sub
End Class
And then bring the control onto a page like so:
<ucl:CustomControl runat="server">
<SomePanel>
<asp:Label ID="lblText" AssociatedControlID="txtBox" runat="server"></asp:Label>
<asp:TextBox id="txtBox" runat="server"></asp:TextBox>
</SomePanel>
</ucl:CustomControl>
When I run the page, HasControls is true but nothing is rendered. What am I doing wrong?
Pretend i have an existing web-site, e.g.:[URL]i now want to expose a mobile version of this web-site:
m.stackoverflow.com
IIS, with its host-header name resolution, would normally require two web-sites to be created:
www.stackoverflow.com
m.stackoverflow.com
Except now i have two web-sites in IIS. This means i have to duplicate code/files between them. i don't need to (nor do i want to) duplicate all the "model" and "controller" code between two web-sites. i would much rather have one web-site that exposes a mobile version.
i could have the default page in m.stackoverflow.com simply perform a redirect to a mobile landing page on the "real" web-site:
m.stackoverflow.comdefault.asp:
<% Response.Redirect "www.stackoverflow.com/mobile" %>
Then the client will end up at (for example) www.stackoverflow.com/mobile/default.aspx.
This isn't what i want. i want it to appear to the browser that they are visiting m.stackoverflow.com.
So what i could do in IIS is have two host-header names for one IIS web-site:
stackoverflow.com
m.stackoverflow.com
and inspect the http-request HOST header: [URL]
Host: stackoverflow.com

I'm having trouble exposing a method to a silverlight client from a WCF service although I can expose properties.
My WCF service has a LoadDeal method which returns a Deal object
public Deal LoadDeal(int dealerId)
{
Deal d = new Deal();
d.LoadDeal(dealerId);
return d;
[Code]....
This works fine and the Refernce property can be accessed from the silverlight client.
But when I try to expose a method such as the CancelEdit method below, I can't find a way to expose this method to the silverlight client:
public void CancelEdit()
{
//Add logic to cancel changes here.
}
I've tried adding the DataMember annotation but the compiler complains. I've re-compiled without an annotation and then updated the service reference but nothing seems to be working.
I have a WCF service with two operations GetLoan and GetBalance
I want GetBalance to be exposed to all the clients but GetBalance tobe exposed to specific clients
How can this be done?
