Using a RegularExpressionValidator, I want my textbox to accept a max of 20 chars, and only English characters A-Z (upper and lowercase), 0-9, hyphens (-), underscores (_), and spaces. That's it.
Now that I think about it, since this text will be used by a proprietary software to create a file of the same name, and will also be included in the querystring when the page is redirected (so that I can find the file so the user can download it), I'm not sure if I should keep it safe and not accept spaces.
I then retrieve the data from the DataTable into an anonymous type:
var feeds = from feed in categoryProducts.AsEnumerable()[code]....
This all works great.
However, I would like to extend the code to perform some evaluation checks (e.g., check that various columns in the DataTable are not NULL) and other pre-processing (e.g., call various functions to build the image URL based on the image ID - which is another column in the DataTable not shown in the code fragment) before I return the resulting rows of the DataTable as an anonymous type to the client-side.Basically, I want to iterate through the DataTable, perform the evaluation checks and pre-processing, while building my anonymous type manually as I go. Or maybe there is a better way to achieve this?
[ActionName("about-us")] public ActionResult EditDetails(int id) { // your code }
The above works for actions but I would like to be able to do the same (or similar) for controllers, ie have a hyphen in the URL name too. Is there any easy way to achieve this (I tried the ActionName attribute but no luck)
I am attempting to compare one of ASP.NET's membership userID's with the current userID in an SQL query, however because of the "hyphens -" in the uniqueidentifier field type of userID, i am unable to compare the ids. is there a way around this? (in my example, family_id from tblFamily is the userID that has type uniqueidentifier). my code as it stands is:
Dim UserID As String = New String(Membership.GetUser(User.Identity.Name).ProviderUserKey.ToString()) Response.Write(UserID) Dim strConn As String = ConfigurationManager.ConnectionStrings("ApplicationServices").ConnectionString Dim SQLI As New Data.SqlClient.SqlCommand("SELECT family_name FROM tblFamily WHERE [family_id] IS " & UserID & "") Dim sqlCon As New Data.SqlClient.SqlConnection(strConn) sqlCon.Open() SQLI.Connection = sqlCon Dim RSI As Data.SqlClient.SqlDataReader = SQLI.ExecuteReader() RSI.Read() Dim FamilyName As String = "0" While RSI.Read FamilyName = Convert.ToString(RSI("family_name")) End While Response.Write(FamilyName) RSI.Close() sqlCon.Close()
I've heard from a couple of different sources that when using HTML helpers in ASP.NET MVC2, one can create custom attributes with dashes in them (e.g. <a data-rowId="5">) by using an underscore in place of the dash, and when the HTML is written to the page the underscores will be replaced by dashes.
So, something like this:
<%= HtmlActionLink(Model.Name, "MyView", null, new {data_rowId = Model.id}) %>
should render as
<a data-rowId="0" href="myURL">Row Name</a>
But... it's not. I think that maybe this feature is only enabled in the MVC3 Beta preview (as it's mentioned in the MVC3 preview release notes), but this thread is about the same thing, and it's regarding MVC2.
I know I can use the other solution presented in that thread, but I'd rather not have to resort to using the dictionary if a more elegant solution exists.
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
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
I know how to bind a simple objects to a dropdown list. However I am having problems binding my objects which contains sub objects to the control.i.e. with simple object i just do ddl.DataValueField = "myproperty" with my objects they contains sub objects which i want to bind. I have tried ddl.DataValueField = "sub-object.myproperty" which doesnt work.
firstly a static class only ever exists once and is not an instance. Any static members (ie static int NoOfPeople;) is stored in one place and is shared between all sessions (like the old global variables). Now static methods is where i'm not 100% sure. If I have a static method that doesn't use any other static members could this cause inconstant results, example (this is a fairly pointless method but just a quick example of the top of my head)
[Code]....
So in this example if two sessions (or threads) were to call this at the same time - would they both get back the expected results, because the method only uses private data (a, b and totalToReturn).Im sure this sounds a little simple but I will be using static methods to build user objects and various other objects that there will have to be a 100% garentee that the objects will not get mixed up between sessions and the wrong things return to the user.
I'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?
Lets say I am doing a shoping cart. I authenticate the user with a session variable.For example:
If(Request.IsAuthenticated) // Here I want to add to the shoping cart. // Can I do the following Session["Cart"] = "Washing Machine"; Now will this Session["Cart"] value which is washing machine here be unique to diff customers?
My web app (asp VB 2005) uses Windows authentication. If the user isn't part of a specific AD security group they don't get to edit the data; instead I redirect the user to a read-only page.The program works fine in the IDE.I published the web app to my laptop and Disabled anonymous access. When I ran the program I got redirected to the read-only page. I added a write event to the application event log to see what was going on, and found that the WindowsPrincipal.Identity.Name contained my laptop's ID, not my user name.I reassert: anonymous access is disabled in IIS and the web.config file has Windows Authentication.
I am working on an internal application... i setup IIS 7 to use windows authentication since its behind the firewall and on the domain.. there is a "public" side.. and an "internal" side... if your not part of IT.. you should get the public side.. this is just informational.. my problem is that there is 1 or two pcs that are not on the domain and nobody is logged into them.. how can i just redirect anonymous users to another site?
everything i read says you can't use anonymous AND windows auth.. so my thought was to just redirect the anonymous users to another site.. how can you do that?
I am trying to figure out how to get at an anonymous typed object's properties, when that anonymous type isn't created in the current function.
Specifically, I am binding an ASP.NET ListView to LINQ resultset, then trying to process each item in the ItemDataBound event.
Option Explicit On Option Strict On Class MyPageClass Private Sub Bind() Dim items As ItemData = FetchItemData() Dim groups = From s In items Group s By Key = s.GroupId Into Group _ Select GroupID = Key, GroupData = Group ' This works fine: Dim groupId As Integer = groups(0).GroupID lvGroups.DataSource = groups lvGroups.DataBind() End Sub Private Sub lvGroups_ItemDataBound(ByVal sender As Object, ByVal e As ListViewItemEventArgs) Handles lvGroups.ItemDataBound If e.Item.ItemType = ListViewItemType.DataItem Then Dim item As ListViewDataItem = DirectCast(e.Item, ListViewDataItem) Dim groupData = item.DataItem ' This is the anonymous type {GroupId, GroupData} ' Next Line Doesn't Work ' Error: Option Strict disallows late binding Dim groupId As Integer = groupData.GroupId End If End Sub End Class
What do I need to do in lvGroups_ItemDataBound() to get at the item.DataItem.GroupId?
Basically, I have a repeater control, and a Linq query that retrieves some items. Ordinarily I would databind straight to the query and use Eval to populate the template with the results.
However, it doesn't come through in quite the right format - for example, if EndDate is null (it's a DateTime?) then I want to substitute it with "Present". I am using only a couple of the properties in the query result objects.
I use LinqToSql in my project. I have a class called MessageBLL and this class has a method called GetAll which returns List<object>. I returned object because I get data from two tables. Here is my code;
[Code]....
I want to use this in my Default.aspx.cs as like this but intellisense is not show CategoryName :[Code]....suggest me return as IQueryable but I couldn't do it in that way.
I have a Postgre profile provider that runs ok with membership, roles, profiles etc.. But I have a problem.I'm trying to have a anonymous user profile but the provider get an error when I try to save the profile.It says:
Error 23503: insert or update on table "profiles" violates foreign key "pofiles_username_fkey"I configured my web.config with anonymousIdentification enabled, and profile ok, But it seems that when the profile saves, it can not find the anonymous user in the users tables that it's related with profles user. I googled for long time and I think I have all good configurated, but somehow, profiles with anonymous user is not working.
I'm looking for a way to configure caching only for anonymous users only. The reason I'm looking to do this is when users are logged in and they create content they don't immediately see the content. In our old system (linux/php/mysql) we had it configured to cache only the anonymous users and this wasn't an issue.
Right now we have caching setup in the web.config like this
[code]....
I know that I can add a varyByCustom="userName" like this post is talking about. But this doesn't solve my problem. It still caches the users login and the same problem exists.
Do any one know how to return an anonymous type. I am using Linq where i need to return the following code
private <What's the return type to be provided here> SampleLinq(Int32 Num) { var query = (from dept in obj.DeptTable where dept.Id == Num select new { dept.DeptName, dept.DeptId }); return (query) }
I'm trying to add a directory for anon access in IIS 7.5. It works under Web Dev but not IIS 7.5
I'm currently using this web.config in the directory. This is a directory with style sheets:
<?xml version="1.0"?>
Note: As an alternative to hand editing this file you can use theweb admin tool to configure settings for your application. Use the Website->Asp.Net Configuration option in Visual Studio. A full list of settings and comments can be found in machine.config.comments usually located in WindowsMicrosoft.NetFrameworkv2.xConfig
I've went to the folder and under Authentication, I've changed anonymous authentication from IIS_USR to pool. This seems to have correct it.
I will reward anyone who provides a very good explanation and resources for understanding this setting. Also, how to apply it globally would be good to know -- for all folders.
