I have to return collection of parent and child objects in a web service but I am not being able to solve this.
look below code blocks where i will try to explain my problem:
This is my web method which returns a list of parents
[Code]....
[Code]....
Below is my child Class:
[Code]....
I have following doimain objects:
public class ComponentType
{
public int ComponentTypeID { get; set; }
public string Component_Type { get; set; }
public string ComponentDesc { get; set; }
}

How is it possible to return some kind of list from a wcf serivce, this the method in my wcf service
my interface:
[Code]....
and this how my GetRootLocations looks like, It returns IQueryable, I wounder if I can maybee return Iqueryable from my svc-service?
[Code]....
I am developing an application with WCF services. The basic functionaloty of a screen is to provide an entry screen to add particular entity. Once save even fired It will save the data to the database and call the bind method to bind into the grid by refreshing the latest data.
When I am running the site from my source (Visual Studio) , it works perfectly. When the client calls method to fetch the data the WCF service, it returns latest (added) data. But the issue comes in the server when it works with IIS. I deployed the code in the server, once the data added I am getting the old data only. But after two refresh I am getting the latest data.
what required to be done to get the latest record.
I am trying to deploy a wcf service. I have created a simple service, basically I have created a new wcf service and tried to deploy it however I get this error
The type 'WCF_Application.Service1', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.
I am trying to deploy my service to a subdomain like
https://services.mydomain.com/business
My config looks like this
[Code]....
Ok so I am trying to setup a WCF web service. I thought I had my .svc and webConfig ready to go, but when I hit this service all I get is a blank page.

I'm using a web service and I want to return a list to my client. I am nearly newby at web services and I can't return a List<String> object to my client. But when i call the method it says "Unable to cast object of type 'System.Collections.Generic.List`1[System.String]' to type 'System.String[]'" What should I do?
View 2 RepliesI've been reading quite a few tutorials on web services and xml files and one thing isn't quite clear to me. If I want to create an XML file on the fly the tutorials are pretty straight forward but, I want to grab an existing XML file from the web server and return the whole thing. Do I need to read the XML file and send each individual node or is there a way to send the file all at once? The tutorials imply that the whole file could be a node but I'm not clear on what that entails or if it would work. Also do you have a link to an example?
View 1 RepliesI Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.
I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).
My present code for converting the table data to the xml format is below.
public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");
[Code]....
I need to eliminate this way of generating xml for each table records.
Simple and blunt: my cascading dropdownlists clear when a postback occurs. Does anyone know a quick way around that?For more information, read on...
I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project). I've built the SQL Select statement behind the lists that filters (accurately).
have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>
In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes
itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.
I have a WCF service with cyclic references that I was using the CyclicReferencesAwareAttribute attribute (http://chabster.blogspot.com/2008/02/wcf-cyclic-references-support.html) to solve. However now I want to use the same service with a Silverlight client. Receiving data works well on the Silverlight client with this method, however the CyclicReferencesAwareAttribute attribute does not work on the Silverlight side when I want to send objects back again.
I have changed to use the IsReference property on the data contract which is supposed to get round with this issue. However now the objects that are returned are empty! (All fields are either default or null). This is the same in my ASP.NET client (original) and my Silverlight client.
Has anyone hit is issue before? Here is the attribute [System.Runtime.Serialization.DataContract(Namespace="http://testnamespace.co.uk/entities", IsReference=true)]
Is it possible to refresh parent page from child's child page using javascript.
I have a webform which opens a child window, a button on child window closes the present child window and opens a subchild window. Now a button on subchild should close the window and refresh the parent form.

Consider this abstract class
public abstract class Foo
{
public Injectable Prop {get;set;}
}
i have an application that i want to enhance and simultaneously refactor for simplicity.
I have over 100 classes that call some same stuff (e.g Class Injectable) and i am thinking that this behaviour can be abstracted and set to a base class, and everybody will inherit from this base class so as to remove copy/paste code.
However, i want to avoid copy/paste code in the spring configuration file by defining an Injectable object and then define a child object foreach and every class that inherits from Foo.
I am looking for a way to set the abstract class's properties and then all child elements to automatically get them via configuration. I want to avoid to make the abstract class like this:

I want to be able to update a model and all its collections of child objects in the same view. I have been referred to these examples: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx and http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/ .
For example, I have an object Consultant, that has a collection of "WorkExperiences". All this is in an Entity Framework model. In the view, the simple properties of the Consultant object is no problem, but the collection I cannot get a textbox to show up for. I tried following the examples in the links above, but it doesn't work. The problem is, in those examples the model is just a list (not an object with a child list property). And also, the model again is an EF model. And for some reason that doesn't seem to work as in those examples.
[Code]....
This stuff with the EditorTemplate works fine in Phil Haack's sample project, which I downloaded to try, but here, with the EF model or whatever the problem is, I don't get any textbox at all. The table in the view is just there as a test, because in the table I do get the rows for WorkExperiences, whether I add an empty WorkExperience object or fill out its properties doesn't matter, the rows show up for each object. But again, no textbox...
I have a nested child and parent UpdatePanel. The problem is, when the child UpdatePanel is refreshed/posted, the UpdateProgress in parent fires up. How can I prevent this? The structure is like this:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate></ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate></ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional">
<ContentTemplate>
<asp:UpdateProgress ID="UpdateProgress3" runat="server" AssociatedUpdatePanelID="UpdatePanel2">
<ProgressTemplate></ProgressTemplate>
</asp:UpdateProgress>
</ContentTemplate>
</asp:UpdatePanel>
</ContentTemplate>
</asp:UpdatePanel>
When UpdatePanel2 is posted, UpdateProgress3 is not displayed but UpdateProgress1 and UpdateProgress2 are. What should I do?
I am new to xml, i want to looping through the below xml and save the records in the database. the below xml is parent child combination, parts as to be saved under respective parents. if the source field is M then there will be child item for that.

In asp.net, I have a parent and a child control. Within the child control I have a dropdown list. Based on dropdown list's selected value I would like to toggle Visibility of Panel in parent control. For instance if I select Show in child control dropdown list, I need to pass true to parent control to make Panel visible and vice versa. How should I do that. I have read that can be done via the event handling and have seen certain scenarios but I am not clear on that.
View 3 Repliesi am working on POCO entities. i had a requirement to provide Edit feature for parent and respective Child records in single View.
Eg: Parent-Customer, Child-Order tables
when updating the parent entity by using => UpdateModel(CustomerIns);
and updating the child entity by using => TryUpdateModel(CustomerIns.Order, "Orders");
The Child Controls Names are like Orders[0].OrderID,Oders[0].OrderDate,etc
The Parent and Child Entities are updating when UpdateModel() is called but when saving Changes by calling Context.SaveChanges() i am getting exception like:
"The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted."
I have an xml document that has a structure like so:
<?xml version="1.0" encoding="iso-8859-1" ?>
- <newdataset xml="version="1.0" encoding="iso-8859-1"">
- <officelist>
<officeid>2</officeid>
<office>Office</office>
<region>BC</region>
I would like to have the office id = 2 to be its own element. Like so
<?xml version="1.0" encoding="iso-8859-1" ?>
<newdataset xml="version="1.0" encoding="iso-8859-1"">
<officelist>
<officeid id=2/>
<office>Office</office>
<region>BC</region>
</officeid>
</officelist>
</newdataset>
xmlDS += offices.GetXml();
xmlDS = xmlDS.Replace(@"xml:space=""preserve""", " ");
XmlDocument doc = new XmlDocument();
XmlNode declaration = doc.CreateNode(XmlNodeType.XmlDeclaration, null, null);
doc.LoadXml(xmlDS);
doc.Save(Response.OutputStream);
That is my code so far... not sure how to set a child node to become a parent node

I am building treeview using asp.net 2.0/3.5 from master detail table.
ParentTable Value

---GrandChildTable1 Node
---GrandChildTable1 Value
---GrandChildTable2 Node
---GrandChildTable1 Value
I have created something like this to populate node values. But I am not sure how to display GrandChildNode and values. Could you please let me know if there are any ideas?
protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e)

switch (e.Node.Depth)

break;
case 1:
GetChildTableValues(e.Node);
break;
case 2:
