How to cast integer values as an array of enum values?


Hello all!

I'm working with VS2010 Beta2, ASP.NET and Dynamic Data. I'm using VB but will certainly be happy to receive a C# example if necessary. Laughing

I used a few of Steve's examples (Writing Attributes and Extension Methods for Dynamic Data and Dynamic Data - Hiding Columns in selected PageTemplates) to create a custom property attribute to be applied to a dynamic data column and want it to accept an array of enum values (each value will represent a dynamic data page template where this column should not be displayed).  My new attribute works fine when I hardcode it like this, meaning the HideColumnIn attribute is properly populated with the array of enum values:

<HideColumnIn(PageTemplate.List, PageTemplate.Edit)> _
Public Property My_DD_Column As Object


However, I want to store the values to be used for the HideColumnIn in the DB as integer values that correspond to the

How to switch between HTTP and HTTPS in ASP.NET MVC2


ASP.NET MVC2 has the new RequireHttpsAttribute that you can use to decorate any action to force any non-secure request to come through HTTPS (SSL).  It can be used as simply as this:

        public ActionResult LogOn()

Now any request to the LogOn action that is not over HTTPS will automatically be redirected back to itself over HTTPS.  This is very useful and easy to implement.

Unfortunately though, once the scheme is changed to HTTPS, all following requests will also be under HTTPS, which is not necessarily what you want.  In most cases you do not need all requests to your site to be secure but only certain ones such as the logon page or pages that accept credit card information. 

To handle this you can override the Controller.OnAuthorization method.  From within this method, you can check to see if the RequireHttps attribute is set on the Controller Action by searching the Attributes collection of the ActionDescriptor object. If the RequireHttpsAttribute is not set AND the request is under SSL, then return a redirect result to the HTTP (no

Switch views when opening a form depending on submit locations?



I would like to know it was possible to switch views when opening a form depending on where the form has been submitted.

I am submitting my form to library A and library B and want to be able to open it in view 1 in library A and in view 2 in library B.

Is there a way to set some url conditions in the open behavior rules?

Thanks a lot!

Bug: Specifying values in the definition of an enum in Web Parts in subsites

Pardon the cumbersome title, but I wanted to make it as descriptive as possible! Anyway, I stumbled upon this bug and spent a good while trying to figure out what was wrong. I'm developing a WebPart for use in MOSS 2007. The WebPart in question is mostly unremarkable, but I was getting the following error when editing the WebPart properties: "Some of the properties for this Web Part cannot be displayed properly. For more information, see your site administrator." I've searched Google, Bing and Yahoo for this error and have found nothing, so hopefully this post will be of use to anyone else who searches for it. Turns out the problem was in the enumerator definition. It looked like this:   public enum KPIPalette { Grey = 1, Green, Blue, Orange }   The colour palettes of the components we're using started at 1, so I set the enumerator to do that also. SharePoint, however, had other ideas. The solution is to leave enumerator definitions out. When the number was required later in code, a 1 was added. Error begone, problem solved!

How to cast integer values to an array of enum values?

Hello all! I'm new to VB.NET (and OOP in general) and am struggling a bit...  I'm working with VS2010 Beta2, ASP.NET and Dynamic Data, however I'm thinking this question may be more related to VB so hopefully I've chosen the correct forum. I have a list of integer values stored in the DB and would like to cast them to an array of enum values so that they may be passed to my constructor.  The values in the DB directly correspond to the enum values.  Here is stripped down version of the code that hopefully highlights what I'm attempting to do:Private _pageTemplate() As PageTemplate Public Sub New(ByVal ParamArray pageTemplateArray As PageTemplate()) _pageTemplate = pageTemplateArray End Sub Public Enum PageTemplate Details = 1 Edit = 2 Insert = 3 List = 4 ListDetails = 5 End Enum What I'm having difficulty with is reading integer values from the DB and casting them to an array of PageTemplate() to be passed to the constructor above.  The integer values in the DB will be 1 through 5 to correspond to the enum values listed above.  Here is how I'm trying to build the ParamArray to be passed to the attribute constructor:Dim hideFieldsIn(-1) As PageTemplate Dim rowCount As Integer = -1 If reader.HasRows Then While reader.Read() rowCount += 1 ReDim hideFieldsIn(rowCount)

How to switch to a different Web Part page layout?

I'm not sure if the capabilities are available in SP2010, but I have a web part page that I would like to change to a different layout. In the past I have always recreated the page, which takes a ton of time, but I would rather switch to a different layout on the fly and move everything around again. Is this possible?

How to expose an enum type to a client via WCF if it isn't used as a param type in any service oper

Hi,   I want to 'expose' an enum type from my server via WCF so that my client can access it. This happens automagically if I use the enum as a parameter type within a service operation, however, what if the particular enum isn't part of any service operation?   In other words, I've defined serveral enums within my Server that are quite useful to my client (even though they don't appear in any of my paramter declarations for the service operations).   The only way I can get this to work is simply create dummy service operations that contains these enum's as arguments. The MEX page then exposes these types for my client to use, but this seems a bit naff.   Thanks   Paul.

Javascript error when attempting to switch page layouts in SharePoint 2010

I hope I put this in the correct forum. I am experiencing the following error when attempting to change the layout of an existing SharePoint 2010 page. But it does not seem to happen on all page types, just publishing pages. This error is happening on both the development server and both test servers. I have look in to the logs, since if it a javascript error there was nothing, which would be expected but I had to try. I have look at the cui.js file but was unable to spend enough time trying to figure out what exactly is going on in this file. Error being received ...
