How To Add A Default Value To A Custom Profile Property
Jun 16, 2010I know you can add defaultValues using the web.config like this:
<profile>
<properties>
<add name="AreCool" type="System.Boolean" defaultValue="False" />
</properties>
</profile>
but I have the Profile inherited from a class:
<profile inherits="CustomProfile" defaultProvider="CustomProfileProvider" enabled="true">
<providers>
<clear />
<add name="CustomProfileProvider" type="CustomProfileProvider" />
</providers>
</profile>
Heres the class:
Public Class CustomProfile
Inherits ProfileBase
Public Property AreCool() As Boolean
Get
Return Me.GetPropertyValue("AreCool")
End Get
Set(ByVal value As Boolean)
Me.SetPropertyValue("AreCool", value)
End Set
End Property
End Class
I don't know how to set the default value of the property. Its causing errors because without a default value, it uses an empty string, which cannot be converted to a Boolean. I tried adding <DefaultSettingValue("False")> _ but that didn't seem to make a difference.
I'm also using a custom ProfileProvider (CustomProfileProvider).

Feb 10, 2011I can create a custom control with a default value:

public bool Exclude { get { return exclue; } set { exclue = value; } }
I can Create the same thing with a nullable property:
private EntityStatuses? status = EntityStatuses.Active;

But how can i then set the property to null in markup when using the custom control?

C# - Setting Property Default Values For A Web User Control?
Apr 15, 2010I am trying to build a web user control and set some default values for its properties in the code-behind like this:
[DefaultValue(typeof(int), "50")]
public int Height { get; set; }
[DefaultValue(typeof(string), "string.Empty")]
public string FamilyName { get; set; }
[DefaultValue(typeof(Color), "Orange")]
public System.Drawing.Color ForeColor { get; set; }
When I add the user control to the page and call it without any properties:
<uc1:Usercontrol ID="uc" runat="server" />
the default values are not set and every property is 0 or null.

MVC 2 - Add A Default Property To A Strongly Typed Html.Textbox Helper
Apr 22, 2010 The strongly typed helpers are now written like this -
<%= Html.TextBoxFor(model => model.State) %>
I need to add a default value to a textbox. In the prior version of Asp.Net MVC it was easy to assign a default value. I thought doing the following would work in MVC 2-
<%= Html.TextBoxFor(model => model.CountyId, new{ value = 840 })%>
This, however, does not work for me in Asp.Net MVC 2. The value is still blank for the textbox. I want to make sure that this isn't some random error that I am having. Has anyone else encountered the same problem? I have searched and searched to find more information on the default property for the html helpers in MVC 2, but I can't find anything. Does anyone out there know how to correctly assign a default value to a textbox in Asp.Net MVC 2?

Custom Server Controls :: How To Custom Controls Derived From Existing Controls - Overriding Default Property Values
Nov 15, 2010I have some (probably very basic) questions about developing custom controls. I am wanting to derive a set of button controls, and the first one I have started on is a "DeleteButton", that has a additional property (DeleteConfirmationText) that is built into the OnClientClick attribute. To get that added, I overrode the Render method as follows:
[Code]....
This all works well. Now, I will add some logic to make sure that there is some text in the DeleteConfirmationText property, but that isn't the intent of my question.
What I am also wanting to do is to override some of the default property values, so I added that to the default constructor:
[Code]....
Now, in the designer in VS2008, and I look at the properties for the control, there isn't a default value shown in the "Properties" section, and the Causesvalidation still shows the underlying classes default value of "True". As well, in design mode, where the GridView control that containse my DeleteButton control would be displayed, there is an error box "There was an error rendering the control. 'Are you certain you want to delete this attorney?' cound not be set on property 'DeleteConfirmationText'. Here's the markup where I am defining the deletebutton control:

Security :: Allowing Access To Default.aspx With Default Document Enabled?
Jan 19, 2011I am trying to secure very mixed content that is located in an ASP.NET directory. For purposes of this question, it can be ~/MyApp/.
I want all of the content in the directory and its subdirectories restricted to authenticated users. The default.aspx page, though, should be accessible to everyone. This is the web.config in that directory:
[Code]....
Now if you are an unauthenticated user, everything works fine if you request [code]....
The problem occurs in that visitors do not always request "Default.aspx". We have a default document configured so that they get Default.aspx even if they just request "/MyApp". An authenticated user works fine, but an unauthenticated user is directed to the login page.
Now I know that essentially this happens because even though the request for "/MyApp/" will actually end up serving up "/MyApp/Default.aspx", the security system is only checking for "/MyApp/" since that is what I requested. That is then getting the default security for the directory.
How can you configure an exception to allow access when no particular file is requested in the directory??
Is there some dependency between DefaultDocumentModule and UrlAuthorizationModule? In this environment, the UrlAuthorizationModule has been removed and re-added in order to make sure it fires for non-managed requests. I would not expect that to change the order of execution, though, since UrlAuthorizationModule usually goes after DefaultDocument.
A workaround could be to set up the opposite security with the directory being open, and then trying to secure individual files. Because of the (changing) number of files, and extensions, etc, and the fact that you cannot use wildcards in a <location>, this is not really a workable solution for me.
Why Does The Default Forms Authentication Cookie Have A Leading Period In It's Default Name
Mar 21, 2011the default ASP.NET Forms Authentication cookie sets it's name as ".ASPXAUTH". Notice the first character is a period? Is there a particular reason for this? Like, does this have an impact on domain names or subdomains for the target domain.
Or is it purely some random thing an MS dev person came up with (maybe to help out the ordering of the cookies, when they were debugging or something .. as text with periods prolly get listed before other strings)?

C# - Why Does ReSharper Need To Scan All Files When Converting A Property To An Auto Property
Mar 4, 2011Is there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?
C# - Difference Between Timeout Property Specified In Web.Config And ExpiryDate Property Of FormsAuthenticationTicket?
Jul 3, 2010In the Web.Config we have a timeout property. Ex:
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>
</authentication>
When loggin in, we can specify a ticket expiry date. Ex:
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);
Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?
