Whenever I want to get selected items I have to loop through each item and see if it's selected. They even have a SelectedItem (no "s" at the end) member which seems odd for a CheckBoxList. It seems like a logical thing to have, does anyone know why they haven't added it?
View 4 RepliesCan a CheckBoxList.SelectedItems be used as a Gridview datasource?
View 8 RepliesI have created a ASP.NET 3.5 web application and in it I have SearchGridView.vb class file in the directory Old_App_Code. This file creates a namespace MyApp.WebControls, which is also referenced in web.config in a namespace tag, as well as included as an import directive at the beginning of my content page. Unfortunately, I receive the following error: Warning 1 Namespace or type specified in the project-level Imports 'MyApp.WebControls' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. Here's the first several lines of my class file SearchGridView.vb:

why this is happening, as well as possible fixes? I cannot impement the asp:SearchGridView due to this error.

View 2 RepliesI have two member roles at my project:
1.) Administrator
2.) Member
From the toolbox in Visual Studio 2008, I have dragged and dropped the create user wizard into the stage. I aim that a guest can register itself and automatically join the "member" role. Not the role "administrator". How can I do that?
int val = lstvRecordsCus.SelectedItems[0].SubItems[0];
The returned value is an int in a string datatype. I need the right hand side to return the value in int instead of string.
I tried Convert.ToInt32, it didn't work.
All the values that comes from SelectedItems[0].SubItems[0] is of type int.
I have following model class:
public class WebModel
{
public List<ArticleModel> Articles { get; set; }
}
public class ArticleModel
{
public int ID { get; set; }
public double ValueParam { get; set; }
}
Then I have the controller with the two actions:
[Authorize]
public ActionResult Index()
{
WebModel model = new WebModel();
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
[Authorize]
[HttpPost]
[ValidateInput(false)]
public ActionResult Index(WebModel model, string saveButton)
{
ModelValidation.ValidateWebModel(model, ModelState);
if (ModelState.IsValid)
{
return RedirectToAction("Create", "Article");
}
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
And this is my view:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Web.Models.WebModel>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<%var controller = Session["controller"] as Web.Code.SessionController; %>
<%Html.BeginForm(); %>
<div>
<table width="100%">
<%foreach (var article in Model.Articles)
{%>
<tr style="text-align: right">
<td>
<%:Html.DropDownListFor(m=>m.Articles.FirstOrDefault(f=>f.ID == article.ID).ID, new SelectList(controller.CurrentProdukt.Articles.AsEnumerable(), "ID", "Name", article.ID)) %>
</td>
<td>
<%:Html.TextBoxFor(m => m.Articles.FirstOrDefault(f => f.ID == article.ID).ValueParam)%>
</td>
</tr>
<%} %>
</table>
</div>
<table style="width: 100%">
<tr>
<td>
<input type="submit" name="saveButton" value="Save" />
</td>
</tr>
</table>
<%Html.EndForm(); %>
</asp:Content>
If I press the submit button, I get to the second action method in the controller (the one with the HttpPost attribute). In this action, the object model itself is not null, but the "Articles" list inside is null.
I use ResolveClientUrl to include css files in my page. When launched through web-server everything is OK, but in design mode css styles are not applied to the page. I use VS 2010 beta 2.
<link href= "<%= ResolveClientUrl("~/Styles/Site.css") %>" rel="stylesheet" type="text/css" />
Same thing happens when I use any expression to specify an url for css How can I fix it? Or is it a bug of beta?

I'm trying to create a member section for my website and a non member section. I want the nonmember pages to have access to all the member pages but just not certain features like saving to the database. Is there a way to have the same page for both members and non members but have certain controls like buttons and other things that are only usable to the member that is logged in?

I'm about to design my Web service API, most of the functions of my API is basically very simular to my web application. Now the question is, should I create 1 single method and reuse them for both the web application and the web service api? (This seems to be the logical solution, however its very complicated; it's much easier to duplicate the method used by the web application, and keep both separate, ie one method for the web application and one method for the web service.)
1) REUSE: one main method and reuse them for both web application and web service application (I like this but it's complicated)
WebAppMethodX --uses-->
COMMONFUNCTIONMETHOD_X
APIMethodX ---uses---->
COMMONFUNCTIONMETHOD_X
ie Commonfunctionmethod_x contains reusable set of common features
PRO: less code, less maintenance, less bugs.
CON: very complicated
2) DUPLICATE: two methods, one method for the web application and one method for the web service.
WebAppMethodX
APIMethodX
PRO: simple
CON: duplication = more code, more maintenance, more bugs!

BC30456: 'RenderPartial' is not a member of 'Html'.
<asp:Content ID="Content1" ContentPlaceHolderID="Head" runat="server">

'DropDownListFor' is not a member of 'Html'
<li>* Choose Country

It's odd because all instance of 'Html' at Views are getting such errors. I did build/rebuild/clean the project but still the same errors.
I'm building a Javascript application and eash user has an individual UserSession. The application makes a bunch of Ajax calls. Each Ajax call needs access to a single UserSession object for the user.
Each Ajax call needs a UserSession object.
Data in the UserSession object is unique to each user.
Originally, during each Ajax call I would create a new UserSession object and it's data members were stored in the ASP.NET Session. However, I found that the UserSession object was being instantiated a lot. To minimize the construction of the UserSession object, I wrapped it in a Singleton pattern and sychronized access to it.
I believe that the synchronization is happening application wide, however I only need it to happen per user. I saw a post here that says the ASP.NET cache is synchronized, however the time between creating the object and inserting it into the cache another Thread could start construction it's another object and insert it into the cache.
Here is the way I'm currently synchronizing access to the object. Is there a better way than using "lock"... should be be locking on the HttpContext.Session object?
