  • Alert on gridview edit based on permission

    - by Vicky
    I have a gridview with edit option at the start of the row. Also I maintain a seperate table called Permission where I maintain user permissions. I have three different types of permissions like Admin, Leads, Programmers. These all three will have access to the gridview. Except admin if anyone tries to edit the gridview on clicking the edit option, I need to give an alert like This row has important validation and make sure you make proper changes. When I edit, the action with happen on table called Application. The table has a column called Comments. Also the alert should happen only when they try to edit rows where the Comments column have these values in them. ManLog datas Funding Approved Exported Applications My try so far. public bool IsApplicationUser(string userName) { return CheckUser(userName); } public static bool CheckUser(string userName) { string CS = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); DataTable dt = new DataTable(); using (SqlConnection connection = new SqlConnection(CS)) { SqlCommand command = new SqlCommand(); command.Connection = connection; string strquery = "select * from Permissions where AppCode='Nest' and UserID = '" + userName + "'"; SqlCommand cmd = new SqlCommand(strquery, connection); SqlDataAdapter da = new SqlDataAdapter(cmd); da.Fill(dt); } if (dt.Rows.Count >= 1) return true; else return true; } protected void Details_RowCommand(object sender, GridViewCommandEventArgs e) { string currentUser = HttpContext.Current.Request.LogonUserIdentity.Name; string str = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); string[] words = currentUser.Split('\\'); currentUser = words[1]; bool appuser = IsApplicationUser(currentUser); if (appuser) { DataSet ds = new DataSet(); using (SqlConnection connection = new SqlConnection(str)) { SqlCommand command = new SqlCommand(); command.Connection = connection; string strquery = "select Role_Cd from User_Role where AppCode='PM' and UserID = '" + currentUser + "'"; SqlCommand cmd = new SqlCommand(strquery, connection); SqlDataAdapter da = new SqlDataAdapter(cmd); da.Fill(ds); } if (e.CommandName.Equals("Edit") && ds.Tables[0].Rows[0]["Role_Cd"].ToString().Trim() != "ADMIN") { int index = Convert.ToInt32(e.CommandArgument); GridView gvCurrentGrid = (GridView)sender; GridViewRow row = gvCurrentGrid.Rows[index]; string strID = ((Label)row.FindControl("lblID")).Text; string strAppName = ((Label)row.FindControl("lblAppName")).Text; Response.Redirect("AddApplication.aspx?ID=" + strID + "&AppName=" + strAppName + "&Edit=True"); } } } Kindly let me know if I need to add something. Thanks for any suggestions.

  • Comparison operators not supported for type IList when Paging data in Linq to Sql

    - by Dan
    I can understand what the error is saying - it can't compare a list. Not a problem, other than the fact that I don't know how to not have it compare a list when I want to page through a model with a list as a property. My Model: Event : IEvent int Id string Title // Other stuff.. LazyList<EventDate> Dates // The "problem" property Method which pages the data (truncated): public JsonResult JsonEventList(int skip, int take) { var query = _eventService.GetEvents(); // Do some filtering, then page data.. query = query.Skip(skip).Take(take); return Json(query.ToArray()); } As I said, the above is truncated quite a bit, leaving only the main point of the function: filter, page and return JSON'd data. The exception occurs when I enumerate (.ToArray()). The Event object is really only used to list the common objects of all the event types (Meetings, Birthdays, etc - for example). It still implements IEvent like the other types, so I can't just remove the LazyList<EventDate> Dates' property unless I no longer implementIEvent` Anyway, is there a way to avoid this? I don't really want to compare a LazyList when I page, but I do not know how to resolve this issue. Thank you in advance! :)

  • MVC 3 ModelView passing parameters between view & controller

    - by Tobias Vandenbempt
    I've been playing with MVC 3 in a test project and have the following issue. I have Group & Subscriber entities and those are coupled through a SubscriberGroup table. Using the DetailView of Group I open a view of SubscriberGroup containing all subscribers. This list has the option to filter. So far it all works, however when I call the AddToGroup method on the controller it fails. Specifically it goes into the method but doesn't pass the subscriberCheckedModels list. Am I doing something wrong? View: SubscriberGroup Index.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.master" Inherits="System.Web.Mvc.ViewPage<Mail.Models.SubscriberCheckedListViewModel>" %> … <h2 class="common-box-title"> Add Subscribers to Group</h2> <p> <% using (Html.BeginForm("Index", "SubscriberGroup")) { %> <input name="filter" id="filter" type="text" /> <input type="submit" value="Search" /> <%} %> </p> <% using (Html.BeginForm("AddToGroup", "SubscriberGroup", Model,FormMethod.Get, null)) { %> <fieldset> <div style="display: inline-block; width: 70%; vertical-align: top;"> <% if (Model.subscribers.Count() != 0) { %> <table class="hor-minimalist-b"> <tr> <th> Add To Group </th> <th> Full Name </th> <th> Email </th> <th> Customer </th> </tr> <% foreach (var item in Model.subscribers) { %> <tr> <td> <%= Html.CheckBoxFor(modelItem => item.AddToGroup)%> </td> <td> <%= Html.DisplayFor(modelItem => item.subscriber.LastName)%> <%= Html.ActionLink(item.subscriber.FirstName + " " + item.subscriber.LastName, "Details", new { id = item.subscriber.SubscriberID })%> </td> <td> <%: Html.DisplayFor(modelItem => item.subscriber.Email)%> </td> <td> <%: Html.DisplayFor(modelItem => item.subscriber.Customer.Company)%> <%= Html.HiddenFor(modelItem => item.subscriber) %> </td> </tr> <% } %> <% ViewBag.subscribers = Model.subscribers; %> probeersel <%= Html.HiddenFor(model => model.subscribers) %> probeersel </table> <%} %> <%else { %> <p> No subscribers found.</p> <%} %> <input type="submit" value="Add Subscribers" /> </div> </fieldset> <%} %> Controller: SubscriberGroupController using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Security; using Mail.Models; namespace Mail.Controllers { public class SubscriberGroupController : Controller { private int groupID; private MailDBEntities db = new MailDBEntities(); // // GET: /SubscriberGroup/ public ActionResult Index(int id) { groupID = id; MembershipUser myObject = Membership.GetUser(); Guid UserID = Guid.Parse(myObject.ProviderUserKey.ToString()); UserCustomer usercustomer = db.UserCustomers.Single(s => s.UserID == UserID); var subscribers = from subscriber in db.Subscribers where (subscriber.CustomerID == usercustomer.CustomerID) | (subscriber.CustomerID == 0) select new SubscriberCheckedModel { subscriber = subscriber, AddToGroup = false }; SubscriberCheckedListViewModel test = new SubscriberCheckedListViewModel(); test.subscribers = subscribers; return View(test); } [HttpPost] public ActionResult Index(string filter) { MembershipUser myObject = Membership.GetUser(); Guid UserID = Guid.Parse(myObject.ProviderUserKey.ToString()); UserCustomer usercustomer = db.UserCustomers.Single(s => s.UserID == UserID); var subscribers2 = from subscriber in db.Subscribers where ((subscriber.FirstName.Contains(filter)|| subscriber.LastName.Contains(filter)) && (subscriber.CustomerID == usercustomer.CustomerID || subscriber.CustomerID == 0)) select new SubscriberCheckedModel { subscriber = subscriber, AddToGroup = false }; SubscriberCheckedListViewModel test = new SubscriberCheckedListViewModel(); test.subscribers = subscribers2.ToList(); return View(test); } [HttpPost] public ActionResult AddToGroup(SubscriberCheckedListViewModel test) { //test is null return RedirectToAction("Details", "Group", new { id = groupID }); } } } ViewModel: SubscriberGroupModel using System.Collections.Generic; using Mail; namespace Mail.Models { public class SubscriberCheckedModel { public Subscriber subscriber { get; set; } public bool AddToGroup { get; set; } } public class SubscriberCheckedListViewModel { public IEnumerable<SubscriberCheckedModel> subscribers { get; set; } } }

  • Compiling code at runtime, loading into current appdomain.

    - by Richard Friend
    Hi Im compiling some code at runtime then loading the assembly into the current appdomain, however when i then try to do Type.GetType it cant find the type... Here is how i compile the code... public static Assembly CompileCode(string code) { Microsoft.CSharp.CSharpCodeProvider provider = new CSharpCodeProvider(); ICodeCompiler compiler = provider.CreateCompiler(); CompilerParameters compilerparams = new CompilerParameters(); compilerparams.GenerateExecutable = false; compilerparams.GenerateInMemory = false; foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies()) { try { string location = assembly.Location; if (!String.IsNullOrEmpty(location)) { compilerparams.ReferencedAssemblies.Add(location); } } catch (NotSupportedException) { // this happens for dynamic assemblies, so just ignore it. } } CompilerResults results = compiler.CompileAssemblyFromSource(compilerparams, code); if (results.Errors.HasErrors) { StringBuilder errors = new StringBuilder("Compiler Errors :\r\n"); foreach (CompilerError error in results.Errors) { errors.AppendFormat("Line {0},{1}\t: {2}\n", error.Line, error.Column, error.ErrorText); } throw new Exception(errors.ToString()); } else { AppDomain.CurrentDomain.Load(results.CompiledAssembly.GetName()); return results.CompiledAssembly; } } This bit fails after getting the type from the compiled assembly just fine, it does not seem to be able to find it using Type.GetType.... Assembly assem = RuntimeCodeCompiler.CompileCode(code); string typeName = String.Format("Peverel.AppFramework.Web.GenCode.ObjectDataSourceProxy_{0}", safeTypeName); Type t = assem.GetType(typeName); //This works just fine.. Type doesntWork = Type.GetType(t.AssemblyQualifiedName); Type doesntWork2 = Type.GetType(t.Name); ....

  • Inject Html Into a View Programmatically

    - by madcapnmckay
    Hi, I have a tricky problem and I'm not sure where in the view rendering process to attempt this. I am building a simple blog/CMS in MVC and I would like to inject a some html (preferably a partial view) into the page if the user is logged in as an admin (and therefore has edit privileges). I obviously could add render partials to master pages etc. But in my system master pages/views are the "templates" of the CMS and therefore should not contain CMS specific <% % markup. I would like to hook in to some part of the rendering process and inject the html myself. Does anyone have any idea how to do this in MVC? Where would be the best point, ViewPage, ViewEngine? Thanks, Ian

  • Reusing datasource

    - by nubby
    I'm tying to use one database call and reuse that data for other controls - without having to do another call. Scenario: I call the books table which returns all the authors and titles. I create an author's list control called list1 to displays all the titles by Shakespeare and a list2 to display titles by Charles Dickens. Void Bindme() { string commandText = "Select * from books"; SqlCommand mycommand = new SqlCommand(commandText, datasource1); datasource1.Open(); SqlDataReader myReader1 = mycommand.ExecuteReader(); list1.DataSource = myReader1; list1.DataBind(); list2.DataSource = myReader1; list2.DataBind(); datasource1.Close(); } In my example only the first bind to the source, list1, gets data. Any ideas?

  • Streaming content from (sharepoint) web part

    - by Mikko Rantanen
    How does one stream files, html or custom AJAX responses from web parts? Our current quick-and-very-dirty solution is to make the web part call the current page with certain query parameters, which the web part checks and instead of performing normal load it writes the required things to output and calls response end. This sounds bad since SharePoint might load other web parts and execute their code before reaching our web part. The web part is configured with data source settings which means the streaming context must be specific to the web part so it can acquire the correct data source settings.

  • OpenExeConfiguration Path Issue

    - by Harry
    I'm trying to load an web.config from a server. Its placed at: \server\folders\web.config when i try this: ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.config"); it searches for: web.config.config and fails. ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web"); it fails, because there is no folder \server\folders\web\ So i tried several things and it seems as its checking wether the file the path is pointing on exists, and afterwards it appliers a .config and gets the config file. Just for fun i created an web.loaders file, and a web.loaders.config file. with ConfigurationManager.OpenExeConfiguration(@"\\server\folders\web.local"); it loads the \server\folders\web.local.config perfectly, but throws Exceptions without the web.local file. So there a many ways to get this small thing loaded, but isn't there a more nice one than using a temp .web file or something? Any help i highly appreciated, yours Harry

  • Replace relative urls to absolute

    - by Rocky Singh
    I have the html source of a page in a form of string with me: <html> <head> <link rel="stylesheet" type="text/css" href="/css/all.css" /> </head> <body> <a href="/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> I want to convert all the relative paths to absolute. I want the output be: <html> <head> <link rel="stylesheet" type="text/css" href="http://mysite.com/css/all.css" /> </head> <body> <a href="http://mysite.com/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="http://mysite.com/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> Note: I want only the relative paths to be converted to absolute ones in that string. The absolute ones which are already in that string should not be touched, they are fine to me as they are already absolute. Can this be done by regex or other means?

  • Linq to Entities custom ordering via position mapping table

    - by Bigfellahull
    Hi, I have a news table and I would like to implement custom ordering. I have done this before via a positional mapping table which has newsIds and a position. I then LEFT OUTER JOIN the position table ON news.newsId = position.itemId with a select case statement CASE WHEN [position] IS NULL THEN 9999 ELSE [position] END and order by position asc, articleDate desc. Now I am trying to do the same with Linq to Entities. I have set up my tables with a PK, FK relationship so that my News object has an Entity Collection of positions. Now comes the bit I can't work out. How to implement the LEFT OUTER JOIN. I have so far: var query = SelectMany (n => n.Positions, (n, s) => new { n, s }) .OrderBy(x => x.s.position) .ThenByDescending(x => x.n.articleDate) .Select(x => x.n); This kinda works. However this uses a INNER JOIN so not what I am after. I had another idea: ret = ret.OrderBy(n => n.ShufflePositions.Select(s => s.position)); However I get the error DbSortClause expressions must have a type that is order comparable. I also tried ret = ret.GroupJoin(tse.ShufflePositions, n => n.id, s => s.itemId, (n, s) => new { n, s }) .OrderBy(x => x.s.Select(z => z.position)) .ThenByDescending(x => x.n.articleDate) .Select(x => x.n); but I get the same error! If anyone can help me out, it would be much appreciated!

  • Different users get the same cookie - value in .ASPXANONYMOUS

    - by Malcolm Frexner
    My site allows anonymous users. I saw that under heavy load user get sometimes profile values from other users. This happens for anonymous users. I logged the access to profile data: /// <summary> /// /// </summary> /// <param name="controller"></param> /// <returns></returns> public static string ProfileID(this Controller controller ) { if (ApplicationConfiguration.LogProfileAccess) { StringBuilder sb = new StringBuilder(); (from header in controller.Request.Headers.ToPairs() select string.Concat(header.Key, ":", header.Value, ";")).ToList().ForEach(x => sb.Append(x)); string log = string.Format("ip:{0} url:{1} IsAuthenticated:{2} Name:{3} AnonId:{4} header:{5}", controller.Request.UserHostAddress, controller.Request.Url.ToString(), controller.Request.IsAuthenticated, controller.User.Identity.Name, controller.Request.AnonymousID, sb); _log.Debug(log); } return controller.Request.IsAuthenticated ? controller.User.Identity.Name : controller.Request.AnonymousID; } I can see in the log that user realy get the same cookievalue for .ASPXANONYMOUS even if they have different IP. Just to be safe I removed dependency injection for the FormsAuthentication. I dont use OutputCaching. My web.config has this setting for authentication: <anonymousIdentification enabled="true" cookieless="UseCookies" cookieName=".ASPXANONYMOUS" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" /> <authentication mode="Forms"> <forms loginUrl="~/de/Account/Login" /> </authentication> Does anybody have an idea what else I could log or what I should have a look at?

  • Dynamically compose ASP MVC view based on context

    - by robertFall
    I have several views that are composed of several partial views based on context. For example, we have a Project view that shows all the details of a project, which includes the scalar values, name etc, and also all the assigned employees, tasks and/or clients. The problem I have is that certain types of project have all of the above sections while others have only two or even on section, ie. details only. What is the best way to compose the Projects master view? I don't want to have logic to check the project in the view. Is there a way to compose a view in code by programatically rendering the relevant partials and ignoring the rest? Otherwise are there any other ideas how to do this in a maintainable way? I could of course just render the partials using if statements to check if they apply, but that way the view contains VERY important logic. In another situation we want to use this method to display content based on the type of subscription a user has. Thanks!

  • Why do SQL connection leave parameters in?

    - by acidzombie24
    While coding with sqlite everytime i always had the exact number of parameters and when i executed the query i always had 0 parameters after it. I kept using the cmd object and it worked fine. Now while porting to use sql server (2008) my SqlConnection has parameters left over from a successful command. Why? I seem to be able to create tables without the problem (then again i may have use a clone of an empty cmd since i use recursion). Does SqlCommand always leave the parameters in after a query? This always breaks the following query unless i do parameter.clear(). Should i create a new SqlCommand object? or use parameter.clear() each time? I'm somewhat confused.
