  • Dynamically Adding Multiple User Controls vb.net

    - by Jamie Hartnoll
    I have a User Control which returns a table of data, which in some cases needs to be looped, displaying one on top of another. I am able to dynamically add a single instance of this by placing a fixed placeholder in the page. I am now trying to work out how to add more than one, given that I don't know how many might be needed I don't want to hard code the Placeholders. I've tried the following, but I am just getting one instance, presumably the first is being overwritten by the second My HTML <div id="showHere" runt="server"/> VB Dim thisPh As New PlaceHolder thisPh.Controls.Add(showTable) showHere.Controls.Add(thisPh) Dim anotherPh As New PlaceHolder anotherPh .Controls.Add(showTable) showHere.Controls.Add(anotherPh) How do I make it add repeated tables within the showHere div?

  • Connection Timeout exception for a query using ADO.Net

    - by dragon
    Update: Looks like the query does not throw any timeout. The connection is timing out. This is a sample code for executing a query. Sometimes, while executing time consuming queries, it throws a timeout exception. I cannot use any of these techniques: 1) Increase timeout. 2) Run it asynchronously with a callback. This needs to run in a synchronous manner. please suggest any other techinques to keep the connection alive while executing a time consuming query? private static void CreateCommand(string queryString, string connectionString) { using (SqlConnection connection = new SqlConnection( connectionString)) { SqlCommand command = new SqlCommand(queryString, connection); command.Connection.Open(); command.ExecuteNonQuery(); } }

  • APS.NET MVC Ajax: Passing a IList from the View to the Controller

    - by Bpimenta
    I need to pass the grid rows from the view to the controller using POST. The idea is to pass an IList of objects (people) that have the following structure: String Name String Address String ID I want to read the data from the JQGrid and pass it to the controller to fill the IList. I'm trying to build the data object to pass through the Ajax data parameter. Here is the Javascript code: $("#saveButton").click( function() { var returnData = '{'; var existingIDs = $('#listPeople').getDataIDs(); if (idsPeople.length > 0) { for (i=0;i<idsPeople.length;i++) { //Trying to build the obejct data ret = ret + '"people['+ i +'].Name":' $('#listPeople').getRowData(idsPeople[i]).Name + ','; ret = ret + '"people['+ i +'].Address":' $('#listPeople').getRowData(idsPeople[i]).Address+ ','; ret = ret + '"people['+ i +'].Id":' $('#listPeople').getRowData(idsPeople[i]).Id+ ','; //If it has more than one element if (idsPeople.length>1 && (i+1)<idsPeople.length) { ret = ret + ','; } } } ret = ret + '}'; My Ajax function for sending: var url_all = '<%=Url.Action("SaveData") %>; $.ajax({ type: "POST", url: url_all, data: ret, dataType: "json", success: function(){ alert("OK"); }, error: function(){ alert("Error: check SaveData"); } }); My controller: public ActionResult SaveData(IList<PeopleHeader> people){ // using debug to know if "people" variable has any values return Json(true); } The problem I'm getting is an error: "System.NotSupportedException: Fixed size collection", and no data is being delivered. I think my problem relies on creating the object... is there any simpler way of doing this procedure? Thanks in advance,

  • Rendering a view to a string in ASP.NET MVC 2

    - by Frank Rosario
    We need to render an ActionResult to a string to add pages to our internal search engine index. We settled on this solution to render to string. I've run into a problem with the ExecuteResult call used to process the View. Code Snippet: var oldController = controllerContext.RouteData.Values["controller"]; controllerContext.RouteData.Values["controller"] = typeof(TController).Name.Replace("Controller", ""); viewResult.ExecuteResult(controllerContext); // this line breaks I receive the following error: "Object reference not set to instance of object" error. I've confirmed viewResult is not null, so the exception has to be thrown internally in ExecuteResult. What could we be missing?

  • Using .net Datetime in sql query

    - by Patrick
    I have a DateTime object I want to compare against an sql datetime field in a where clause. I'm currently using: "where (convert( dateTime, '" & datetimeVariable.ToString & "',103) <= DatetimeField)" But I believe datetimeVariable.ToString will return a different value depending on the culture where the system is running. How would you handle this so it is culture independent?

    This is crazy, I have been trying for hours to get this to work. My client wants to be able to reset password for uses who have forgotten them The only parameter he has is the UserName. He does NOT want the user to be able to reset the password themselves, no that would be too easy...ARGHHHHH!! Anyway, if anyone has any suggestions how I could reset someones password or give them a new temp password somehow, that would be greatly appreciated. Thank you, Steve

  • Possible Encoding Issue Reading HTM File using .Net Streamreader

    - by Brian Boatright
    I have an HTML file with a ® (copyright) and ™ (trademark) symbol in the text. These are just two among many other symbols. When I read the html file into a literal control it converts the symbols to something else. The copyright symbol converts to ? (open box in ff) The trademark symbol converts to ™ (as expected) If (System.IO.File.Exists(FullName)) Then Dim StreamReader1 As New System.IO.StreamReader(FullName) Contents.Text = StreamReader1.ReadToEnd() StreamReader1.Close() End If Contents is a <asp:Literal runat="server" ID="Contents"></asp:Literal> and it's the only control in the aspx page. From some research I think this is related to the encoding but I don't know why it would change how to fix it. The html file does not contain any Content-Type settings in the head section.

  • ASP.NET MVC null ViewResult

    - by David Neale
    How should one deal with an MVC controller returning a null ViewResult? As an example I am creating a simple edit view: public ActionResult Edit(int id) { var person = (from p in context.SWLiftShare_Persons where p.id == id select p).SingleOrDefault(); if (person != null) { return View(person); } else return View(); } I guess in reality there's no point in checking for a null result in the controller because the view picks out properties from the model: <h2>Edit - <%= Html.Encode(Model.Name) %></h2> <%= Html.ValidationSummary("Edit was unsuccessful. Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <p> <label for="id">id: <%= Html.Encode(Model.id) %></label> </p> <p> <label for="CollarNumber">CollarNumber:</label> <%= Html.TextBox("CollarNumber", Model.CollarNumber)%> <%= Html.ValidationMessage("CollarNumber", "*") %> </p> <p> <label for="Name">Name:</label> <%= Html.TextBox("Name", Model.Name)%> <%= Html.ValidationMessage("Name", "*") %> </p> <p> <label for="EmailAddress">EmailAddress:</label> <%= Html.TextBox("EmailAddress", Model.EmailAddress, new { style = "width:300px" })%> <%= Html.ValidationMessage("EmailAddress", "*") %> </p> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> I could just wrap everything in a <% if(Model != null) { //render edit markup... etc. but that seems rather unelegant. Is there a better way to deal with this?

  • How to stream video content in asp.net?

    - by Kon
    Hi, I have the following code which downloads video content: WebRequest wreq = (HttpWebRequest)WebRequest.Create(url); using (HttpWebResponse wresp = (HttpWebResponse)wreq.GetResponse()) using (Stream mystream = wresp.GetResponseStream()) { using (BinaryReader reader = new BinaryReader(mystream)) { int length = Convert.ToInt32(wresp.ContentLength); byte[] buffer = new byte[length]; buffer = reader.ReadBytes(length); Response.Clear(); Response.Buffer = false; Response.ContentType = "video/mp4"; //Response.BinaryWrite(buffer); Response.OutputStream.Write(buffer, 0, buffer.Length); Response.End(); } } But the problem is that the whole file downloads before being played. How can I make it stream and play as it's still downloading? Or is this up to the client/receiver application to manage?

  • VB.NET textbox changed but still hold initial value

    - by Jonesy
    Hi Folks, I've never come across this before: I have a series of text boxes. The text of these boxes get set on page load. then I have a submit button that calls a sub to update the table with the new values (text) in the text box. The problem is it is keeping the original text not the text that is CURRENTLY in the textbox. Anyone come across this before? Or know how to get round it? Cheers, Jonesy

  • How ASP.NET MVC passes model to the view without explicitly passing it

    - by Vlad Bezden
    Here is one of the examples that I've seen on how to do validation on Controller: [HttpPost] public ViewResult Create(MyModel response) { if (ModelState.IsValid) { return View("Thanks"); } else { return View(); } } If there are validation errors, than return View() method is called without any parameters. Obviesly you have @Html.ValidationSummary() in your View and Model has all required properties attributes. The data that was entered into the form was preserved and displayed again when the view was rendered with the validation summary. My question is how data preserved? Since it was not passed to the View like return View(response); Thanks a lot. Sincerely, Vlad

  • set current user in asp.net mvc

    - by Tomh
    Hey guys, I'm not sure if this is the best way to do it, but I want to keep a user object alive during all requests of the current user. From reading several resources I learned that you should create your own IPrinciple which holds this. But I don't want to trigger the database every authentication request. Any recommendations on how to handle this? Is caching the db request a good idea? protected void Application_AuthenticateRequest(Object sender, EventArgs e) { HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); User user; using (HgDataContext hg = new HgDataContext()) { if (Session["user"] != null) { user = (from u in hg.Users where u.EmailAddress == authTicket.Name select u).Single(); } else { user = Session["user"] as User; } } var principal = new HgPrincipal(user); Context.User = principal; } }
