  • asp.net disappearing data from Dropdownlist inside listview when loading from DataTable

    - by piotrmichal
    Hello I have a problem with dropdowllist ddl1 that is inside of insertitem of listview. I populate it from table on page load. In Page_load I have: if (!Page.IsPostBack) { ListView1.DataBind(); InsDropDownList3.DataSource = GetAllPlayersName(); InsDropDownList3.DataBind(); } DropDownList ddl1 = (DropDownList)ListView1.InsertItem.FindControl("InsDropDownList1"); if (ddl1 != null) { DataTable t = GetAllPlayersName(); ddl1.DataSource = t; ddl1.DataBind(); } When I select a row in listview or edit it data from dropdownlist in insertitem row disappears - list became empty until I close page and open again. There is another InsDropDownList3 outside of listview and there is no problem with this one. Why one is loosing data and the other one not? As I understand ddl1 should even get data every time page loads.

  • Asp.net mvc small amount data storage

    - by Trimack
    Hi there, I am writing some learning tests (i.e. what's the answer for...; choose correct options...). Now my question is, how should I store them. SQL db seems quite an overkill, but I really don't know what would be the best choice if I wanted to select random subset of questions etc. Perhaps some simple xml files? Thanks for advice.

  • ASP.NET Writing to the Bin directory, access denied when anonymous user

    - by LeeW
    Hi all I have a program that creates a small file in the Bin directory for the purpose of tracking a license (that's the intention), all works fine when debugging but I've just realized that when I run it on a IIS server under the anonymous user account (IUSR) the file isn't created as IUSR only has read permission (I know this is correct but drat!). Can I write to another location under IUSR account or can I run my code under 'Local Service' account? Thanks

  • How to reference using Entity Framework and Asp.Net Mvc 2

    - by Picflight
    Tables CREATE TABLE [dbo].[Users]( [UserId] [int] IDENTITY(1,1) NOT NULL, [UserName] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [Email] [varchar](255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [BirthDate] [smalldatetime] NULL, [CountryId] [int] NULL, CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED ([UserId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] CREATE TABLE [dbo].[TeamMember]( [UserId] [int] NOT NULL, [TeamMemberUserId] [int] NOT NULL, [CreateDate] [smalldatetime] NOT NULL CONSTRAINT [DF_TeamMember_CreateDate] DEFAULT (getdate()), CONSTRAINT [PK_TeamMember] PRIMARY KEY CLUSTERED ([UserId] ASC, [TeamMemberUserId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] dbo.TeamMember has both UserId and TeamMemberUserId as the index key. My goal is to show a list of Users on my View. In the list I want to flag, or highlight the Users that are Team Members of the LoggedIn user. My ViewModel public class UserViewModel { public int UserId { get; private set; } public string UserName { get; private set; } public bool HighLight { get; private set; } public UserViewModel(Users users, bool highlight) { this.UserId = users.UserId; this.UserName = users.UserName; this.HighLight = highlight; } } View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcPaging.IPagedList<MyProject.Mvc.Models.UserViewModel>>" %> <% foreach (var item in Model) { %> <%= item.UserId %> <%= item.UserName %> <%if (item.HighLight) { %> Team Member <% } else { %> Not Team Member <% } %> How do I toggle the TeamMember or Not If I add dbo.TeamMember to the EDM, there are no relationships on this table, how will I wire it to Users object? So I am comparing the LoggedIn UserId with this list(SELECT TeamMemberUserId FROM TeamMember WHERE UserId = @LoggedInUserId)

  • where should i encode this html data in an asp.net mvc site

    - by ooo
    here is my view code: <%=Model.HtmlData %> here is my controller code: public ActionResult GetPage() { ContentPageViewModel vm = new ContentPageViewModel(); vm.HtmlData = _htmlPageRepository.Get("key"); return View(vm); } my repository class basically queries a database table that has the fields: id, pageName, htmlContent the .Get() method passes in a pageName (or key) and returns the htmlContent value. Right now i have just started this (haven't persisted anything to the db yet) so i am not doing any explicit encoding in my code now. What is the best practice for where i need to do encoding (in the model, the controller, the view ??)

  • Asp.Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea? Update : The error occur in a page extending System.Web.UI.Page in the method InitializeCulture() which is an override.

  • ASP.Net: Finding the cause of OutOfMemoryExpcetions

    - by Keith Bloom
    I trying to track down the cause of an OutOfMemory for a website. This site has ~12,000 .aspx pages and the last time it crashed I captured a memory dump using adplus. After some investigation I found a lot of heap fragmentation, there are around 100MB of Free blocks which can't be assigned. Digging deeper one of the Large Object Heaps is fragmented and the causes seems to be String interning as described [here][1] Could this be caused by the number of pages in the site? As they are all compiled they sit in memory and by looking at the dump they are interned and PINNED which I think means they stick around for a while. I would find this odd as there are many sites with more pages, but dynamic compilation could account for the growth in memory. What other methods are there for finding the cause of the memory leak? I have tried to capture a dump using adplus in hang mode but this fails and the IIS worker process get recycled. [1]: • http://stackoverflow.com/questions/686950/large-object-heap-fragmentation

  • "Cleanly" Deploying an ASP.NET Application with LINQ to SQL Server

    - by Bob Kaufman
    In my development environment, my SQL Server is PHILIP\SQLEXPRESS. In testing, it's ANNIE, and the live environment will have a third name yet to be determined. I would have assumed that updating the following statement in web.config would have been enough: <add name="MyConnectionString"providerName="System.Data.SqlClient" connectionString="Data Source=PHILIP\SQLEXPRESS;Initial Catalog=MyDtabase;Integrated Security=True" /> When using SqlConnection, SqlCommand, SqlDataReader and friends, that's all it took. Using LINQ, it doesn't seem to work that nicely. I see the servername repeated in my .dbml file as well as in Settings.settings. After changing it in all of those places, I get it to work. However if I'm doing a few deployments per day during testing, I want to avoid this regimen. My question is: is there a programmatic solution for LINQ to SQL that will allow me to specify the connection string once, preferably in web.config, and get everybody else to refer to it?

    - by SimonNet
    When I look at gmail on my mobile web browser the password textbox hashes the characters as I type so I can see the actual input as I type before is hashed with an asterisk. So as I enter it becomes, P -- *a -- **s etc.. How is this done? I presume its javascript? If somone can point me in the right direction that would be great.
