WCF / ASMX :: Enum Mapper - C# 3.5 / Easiest Way To Achieve Mapping Without Writing Tedious Switch Statements?
May 25, 2010
We are developing SOA based application using .NET 3.5 and WCF & WPF.
One common issue we are facing is mapping between WCF enum and WPF enums. We had to do mapping between WCF enums to WPF enums. Following is sample code
Switch(WCFServiceObject.Status)
{
Case WCFServiceStatus.Married[code]....
You can see that we have to do mapping WPF and WCF enums. Is there any easiest way to achieve this mapping without writing tedious switch statements? One way of doing this is using Dictionary, but apart from this, is there any good way? We have lots of enums for which have to do mappings.

Is there any design pattern or architectural design that prevent the following type of code, where I have an enum with different fileformats and I have to make a switch anywhere I want to distinguish between the different fileformats?
[Code]....
If add an item to the enum definition in this case I have to change all the code that uses switches and that kind og enum which, I guess, is a bad approach in terms on maintenance of the application?

I am facing an critical problem in Enum serialization in WCF. Here is the scenario: I have an enum like this...
[Serializable] [DataContract(Namespace = "http://www.geniusdoc.portal.com/serivces/2011/v1/GdService", Name = "AppointmentMode")] public enum AppointmentMode : int { // 1: Email, 2: Phone [EnumMember(Value = "1")] None = 1, [EnumMember(Value = "2")] Email = 2, [EnumMember(Value = "3")] Phone = 3 }
Here I decorated each enum value with [EnumMember], so that I can use the Enum as Data Contract in WCF.
And, AppointmentMode will be saved as INTEGER in database. So I need to serialize this Enum to its value. So I have specified value to each member like... [EnumMember(Value = "1")]
Problems:
If I use the above code as it is...SvcUtil not considering Enum Text, and generating the Enum in Proxy as below...
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AppointmentMode", Namespace="http://www.geniusdoc.portal.com/serivces/2011/v1/GdService")] public enum AppointmentMode: int { [System.Runtime.Serialization.EnumMemberAttribute(Value="1")] _1 = 1, [System.Runtime.Serialization.EnumMemberAttribute(Value="2")] _2 = 2, [System.Runtime.Serialization.EnumMemberAttribute(Value="3")] _3 = 3, }
If I remove the Value from [EnumMember(Value = "1")], while deserialization is considering Enum Text, and giving results as below
<AppointmentMode>None</AppointmentMode>
Expected result:
1. Enum in the Client proxy should be same original Enum.
2. Enum Deserialization should consider EnumValue, such a way that it will return
<AppointmentMode>1</AppointmentMode>
How to get this done?

i am generating a wcf data contract from a schema, using svcutil /d: option, however the enum of type xsd:int in schema is generating all the values as ints, with underscores, obviously to make valid code. How can i get the actual value of 1000
E.g Enum Impact with values 1000,2000,3000 generates code
public enum Impact : int
{
[System.Runtime.Serialization.EnumMemberAttribute(Value = "1000")]
_1000 = 1,
[System.Runtime.Serialization.EnumMemberAttribute(Value = "2000")]
_2000 = 2,
[System.Runtime.Serialization.EnumMemberAttribute(Value = "3000")]
_3000 = 3
}

I have a webmethod that has three parameters:
public AuthenticationResult Authenticate(Enum type, string userName, string password) But the problem I had is that if a null/invalid enum is entered for the type variable it throws an error message.
So the obvious solution is to use a string/int instead but I am cannot do this as current users already use the existing webmethod.
So i was thinking:
public AuthenticationResult Authenticate(object type, string userName, string password) and handling the casting myself but the problem I had with this is that now my users do not have access to the Enum type.
So my question is can I publish the enum type without having it as a parameter/return value? Allow the client to access the Enum so they can pass it into the method. Would using a method that returned a type that was my enum work? Or is there a way to catch this custom error: (I dont think so as it appears to be on the client end when converting Enum to xml). The error is: (System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: Instance validation error: '45465' is not a valid value for Enum.)

there's an .aspx page that does absolutely nothing in the codebehind, but contains the markup for the page in the Design View. Then we have an .asmx web service that receives requests with JSON content-type. These are called by the JavaScript in the page. This web service returns .NET objects serialized to JSON in response to these JavaScript Ajax HTTP POSTs. I'd like to switch to MVC but am not sure to how switch this architecture. Basically what we're doing is two things:
1) Replying to GET /MyPage.aspx with HTML markup that represents the page
2) Replying to POST /MyPage.aspx/WebMethodName requests with .NET objects serialized to JSON.
It seems like MVC would be a good way to eliminate the need for a Page object (again, the codebehind isn't used--only the HTML markup in the .aspx file is) and an .asmx web service. No? What do I need to start changing to accomplish this switch? Is it straight-forward? Painful? Someone at work already has an MVC page running in the same directory as my Web Forms .aspx and .asmx web service, but I don't see anything in the directory about Routes, so I'm confused. He's got a Views, ViewModels, and Controllers subdirectories.

I am going to be receiving data in a web service. After I receive this data I will be mapping it to a data transfer object. I want to be able to catch exceptions if the data from the service is missing any of the required values, times out or any data is malformed.
What can I do to generally catch these exceptions?

I'm using the 'Configure Data Source' wizard to connect to my database and show the dataset in Gridview. I want to be able to update, insert and delete entries but am unsure how to build the query. I can write simple update statments to change database entries but how can I do this for entries that have been changed within the gridview?

I am a REST web service newbie, does visual studio, .NET, or some other nifty microsoft tool provide any easy way to auto generate classes to consume a REST web service? With REST services is there even a service definition like there is with SOAP (WSDL) beyond the printed documentation? There is a new service that I'd like to consume but they only wrote wrappers for PHP, Pearl, Ruby, and Java and have more or less said you are on your own with .NET. I could write it myself but I'd like to cut corners and save time wherever possible.

I've been wondering how i go about writing a MembershipProvider that authenticates using a WCF Provider. At the moment i have a wcf service that will authenticate a username and password.
I can write my own Membership provider that will authenticate using WCF calls, thats no problem. What i want is to have the WCF as the actually provider.
Meaning in the web.config file i just put the WCF service as the MembershipProvider. Or is this not possible or not the way this is to be done.

I have a situation where I have two assemblies - one called "business objects" and another called "data mapper". This is to allow me to swap out the data mapper if necessary with no change to business logic.
When loading objects from the database, there are certain methods and properties within these objects that it's convenint to allow the data mapper to access directly so as to simplify the process of construction. However, I'd like to make sure that these methods are only available to the data mapper - because otherwise you can guarantee that some developer will go and use them, short circuiting the business logic.
Even if I prefaced the method names with eg DatamapperOnly, I'd bet that someone would be stupid enough to use them "because we needed to get the application out in a hurry".
Can anyone think of any way to prevent this? For example, is it possible to create a custom <datamapperonly> attribute to be applied to methods which would cause the application to warn the developer at compile time unless the calling program implemented an interface called IDataMapper?

I have run into the issue on DataSet.WriteXml method. Apparently, if any row in a column in the DataSet has a null value, the entire column/rows will not write out in the xml file using the method DataSet.WriteXml. So, as terrible as that bug is, I need to send the data another way. Does anyone have any thoughts?

What's the easiest way to convert a BMP file to a single page PDF using ASP.net? I'm going to generate the 8.5" x 11" BMP in Flash (which means I can manipulate it to make it as easy as possible), then use a POST to upload it to an ASP page, which will convert it to a PDF and redirect the user to the PDF. I don't want to add any margins or anything else, it will be laid out properly in the BMP for full-bleed.Would it be easier to convert it to PDF in Flash, then upload?

I want to reliably and easily Uri encode paths such as "/folder/foo%bar" to "/folder/foo%25bar".
I would have hoped that HttpUtility.UrlPathEncode would do the trick but this method only escapes spaces. I don't want to url HttpUlity.UrlEncode as this will encode "foo bar" to "foo+bar" - which ain't what I want.

I have one page with 3 FormViews + 3 Modal PopUp for them (AJAX toolkit). Works great but I have dependancy. If add a new record in one modal pop up it should be available in another one. I use autocomplete which does the work the problem and I have a hidden combo box where I get the ID for the insert.
Problem? The problem is that when I insert new record it doesn't update the asp combox box (not AJAX) so I cannot get the new id.
What would the easiest way to get ID without doing post backs. I want to avoid post back because the entry in text box might not be valid (partially typed) so I want to make sure it is typed in full so it I can get unique row = ID.

I have a datagrid with sorting. I set enable sorting to true, but that makes every column sortable. Is there a simple way to make it so that only one column header can be clicked for sorting? I feel like there should be a simple and quick fix for this, but who knows. some code:
<asp:GridView ID="ProductsGrid" runat="server"
AutoGenerateColumns="False" Height="323px"
style="margin-top: 23px; margin-left: 0px;" BackColor="White" CellPadding="0"
Width="1210px" OnPageIndexChanging="gridView_PageIndexChanging"
onrowdatabound="ProductsGridView_RowDataBound" AllowPaging="True"
PageSize="25" AllowSorting="True" OnSorting="ProductsGrid_SortCommand">
I then have several columns. Is there something I can set in the code for the column to disable all others or only make one sortable?

I have 2 web sites running on the same server. Web1 needs to transfer data to web2 (same web server, different webs), passing sensitive data from one to the next. The browser will be using https. Are cookies possible/advisable here? My initial thoughts where to encrypt the data and pass through the querystring, both sites using a shared key. Perhaps also pass an encrypted expiration date to prevent the url from being reused in history if it's on a shared computer. Figuring it's https and encrypted, initially it sounds ok. However, my gut tells me its unsecure. Another option is a session server but that seems a bit overkill for what I'm after.
What is the best way to securely transfer a single piece of data from 1 site to the next on the same web and do it relatively simply?

What is the easiest way to include a tooltip in the gridView column?
For example in this column
<asp:BoundField DataField="short_comment" HeaderText="Comments" ReadOnly="True" SortExpression="short_comment"/>
I would like to have something like
<asp:BoundField DataField="short_comment" ToolTipDataField="longer_comment"/>
Obviously the ToolTipDataField does not exist, but what would be the easiest way to achieve that functionality?

I now that I can just define the width and height of a page with the div tag to allow for dragpanels to work, but it messes things up with some browsers when rendering, sometimes shrinking the actual content to allow for the complete page and width to be shown such as on the IPAD. I have tried the Javascript below, but it doesn't work, and whenever I try to resize a page manually, it puts my computer into never never land.
Anyone have a clean Javascript that will change the width and height dynamically as I am moving a dragpanel.
I can move the dragpanel, but it snaps back as soon as I let go so in essense it doesn't work.

I have a selection list that is generated dynamically, it lists a number of checkboxes that are based on an end-user editable table, as such I have no idea what data, or how much, might be contained in this table and how many checkboxes or what they might contain, other than the primary keys of the table. The user will select the checks they wish to see, and then control is passed to another page via PostBackUrl. The second page has to figure out which records to show (build it's where clause) based on the checkboxes checked in the previous page.
So, my problem is several-fold. First, asp:CheckBoxes don't have values. This can be worked around by a number of methods. Right now, i'm using a placeholder and dynamically creating the checkboxes in the ItemDataBound event of the DataList. I set the ID to "CheckboxKey1Key2" (where Key1 and Key2 are the primary keys of the check items). Second, I have to walk through the controls of the PreviousPage to dig out all these values. That in itself is also a pain, but doable. Now, my thinking is to build the where clause of my Linq2Sql query based on the keys I got from decoding the checked checkbox names. This all seems like a lot of jumping through hoops for something that shouldn't be this difficult. Am I missing something? Does anyone have any better solutions?

What is the easiest way to save form data and retrieve it when the user navigates back to the page?
We have an application process that consists of several web forms. If the user clicks to go back a step we would like to auto-populate the fields. I am assuming there is a common generic way to do this without having to mess with individual controls - what is it?
