  • Render asp.net repeater as-and-when chunks of html is ready (streaming)

    - by sash
    The problem is to render huge reports. Basically we have lots of data that get rendered in html reports (mostly using repeater or gridview). As it so happens, the data started out small and now we have tons of it. There are lots of such reports already built so total rewrite is not an option. Heck, the business is not even letting us page the data. Now server memory is shooting up each time we try to render some reports. So the question is - is there some way we can bind data to repeater and have it stream html to browser as and when chunks are ready? That way we hope to not bring all that data into app server at once. I'm thinking we'll use a datareader or something to get parts of data and render it to browser. Any pointers, links, ideas?

  • ASP.NET Web Application: use 1 or multiple virtual directories

    - by tster
    I am working on a (largish) internal web application which has multiple modules (security, execution, features, reports, etc.). All the pages in the app share navigation, CSS, JS, controls, etc. I want to make a single "Web Application" project, which includes all the pages for the app, then references various projects which will have the database and business logic in them. However, some of the people on the project want to have separate projects for the pages of each module. To make this more clear, this is what I'm advocating to be the projects. /WebInterface* /SecurityLib /ExecutionLib etc... And here is what they are advocating: /SecurityInterface* /SecutiryLib /ExecutionInterface* /ExecutionLib etc... *project will be published to a virtual directory of IIS Basically What I'm looking for is the advantages of both approaches. Here is what I can think of so far: Single Virtual Directory Pros Modules can share a single MasterPage Modules can share UserControls (this will be common) Links to other modules are within the same Virtual directory, and thus don't need to be fully qualified. Less chance of having incompatible module versions together. Multiple Virtual Directories Pros Can publish a new version of a single module without disrupting other modules Module is more compartmentalized. Less likely that changes will break other modules. I don't buy those arguments though. First, using load balanced servers (which we will have) we should be able to publish new versions of the project with zero downtime assuming there are no breaking database changes. Second, If something "breaks" another module, then there is either an improper dependency or the break will show up eventually in the other module, when the developers copy over the latest version of the UserControl, MasterPage or dll. As a point of reference, there are about 10 developers on the project for about 50% of their time. The initial development will be about 9 months.

  • VB.NET Syntax Coding

    - by Yiu Korochko
    I know many people ask how some of these are done, but I do not understand the context in which to use the answers, so... I'm building a code editor for a subversion of Python language, and I found a very decent way of highlighting keywords in the RichTextBox through this: bluwords.Add(KEYWORDS GO HERE) If scriptt.Text.Length > 0 Then Dim selectStart2 As Integer = scriptt.SelectionStart scriptt.Select(0, scriptt.Text.Length) scriptt.SelectionColor = Color.Black scriptt.DeselectAll() For Each oneWord As String In bluwords Dim pos As Integer = 0 Do While scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) >= 0 pos = scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) scriptt.Select(pos, oneWord.Length) scriptt.SelectionColor = Color.Blue pos += 1 Loop Next scriptt.SelectionStart = selectStart2 End If (scriptt is the richtextbox) But when any decent amount of code is typed (or loaded via OpenFileDialog) chunks of the code go missing, the syntax selection falls apart, and it just plain ruins it. I'm looking for a more efficient way of doing this, maybe something more like visual studio itself...because there is NO NEED to highlight all text, set it black, then redo all of the syntaxing, and the text begins to over-right if you go back to insert characters between text. Also, in this version of Python, hash (#) is used for comments on comment only lines and double hash (##) is used for comments on the same line. Now I saw that someone had asked about this exact thing, and the working answer to select to the end of the line was something like: ^\'[^\r\n]+$|''[^\r\n]+$ which I cannot seem to get into practice. I also wanted to select text between quotes and turn it turquoise, such as between the first quotation mark and the second, the text is turquoise, and the same between the 3rd and 4th etcetera... Any help is appreciated!

  • asp.net MVC ActionMethod causing null exception on parameter

    - by David Liddle
    I am trying to add filter functionality that sends a GET request to the same page to filter records in my table. The problem I am having is that the textbox complains about null object reference when a parameter is not passed. For example, when the person first views the page the url is '/mycontroller/myaction/'. Then when they apply a filter and submit the form it should be something like 'mycontroller/myaction?name=...' Obviously the problem stems from when the name value has not been passed (null) it is still trying to be bound to the 'name' textbox. Any suggestions on what I should do regarding this problem? UPDATE I have tried setting the DefaultValue attribute but I am assuming this is only for route values and not query string values ActionResult MyAction([DefaultValue("")] string name) //Action - /mycontroler/myaction ActionResult MyAction(string name) { ...do stuff } //View <div id="filter"> <% Html.BeginForm("myaction", "mycontroller", FormMethod.Get); %> Name: <%= Html.TextBox("name") %> .... </div> <table>...my list of filtered data

  • Empty Postbacks on ASP.NET pages

    - by AaronLS
    We are having a problem that seems to only be a problem when accessing our websites from internal intranet machines. When logged into the domain, and accessing our websites, postbacks are not working. Basically the page behaves as if it were refreshed and nothing was changed. When logging the GETs and POSTs with an HTTP analyzer, the post is complete empty and the ContentLength is 0. It is also very sporadic, but seems to be happening fairly often. In the case where it failed, we could see that there was an extra item in the Header for the POST, it was "Authorization" and the value was the word "Negotiate " followed by a space and then a bunch of characters and two equal symbols at the end, which looked like some kind of base64 encoded value. In a case where it succeeded, this Authorization item was no in the header, but I have logged more than one successful cases to know if that is consistent. We have seen this occur only with IE8 so far, and when it occurs it is sometimes sporadic. I can close and open the browser and it will begin working sometimes, and other times it is still broken. What might be causing the postback to be empty? This means the viewstate is not sent to the server which makes the page basically broken. It seems to certainly be a client side issue, but not sure if it's not aggravated by some server settings. Thanks in advance.

  • Get ViewData IList back on postback in ASP.NET MVC

    - by Thomas
    I have the following in my view: <%using (Html.BeginForm()) {%> <% foreach (var item in Model.Cart) { %> <div> <%= Html.TextBox("Cart.Quantity", item.Quantity, new { maxlength = "2" })%> <%= Html.Hidden("Cart.ItemID", item.ItemID)%> </div> <% } %> <input name="update" type="image" src="image.gif" /> <% } % I then have this code in my controller: public ActionResult Index() { CartViewData cartViewData = new CartViewData(); IList<Item> items = ItemManager.GetItems(); cartViewData.Cart = items; return View("Index", cartViewData); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(CartViewData cartViewData) { // cartviewData is null } Is there a way to grab the List on the postback to see if the values in the textboxes have changed? Thanks Below is a simplified example since it was requested: <% for (int i = 0; i < Model.Cart.Count; i++ ) { %> <a href="javascript:void(0);" onclick="removeItem(<%= Model.Cart[i].ShoppingCartItemID %>);">Remove</a> <% } %> Hope this helps.

  • Threading multiple WebBrowser in VB .net

    - by Code_Seeker
    I'm building a multiple webbrowser inside tabs( 1 predefine webbrowser control per tab) and I want them all to load at the same time or other words must run in thread. Unfortunately I feel a valid fact came from the error message that this is something not possible. Pls help me to check my simple program code below and its error in case i tried releasing 2 webbrowser controls but when I leave it to single web browser control it works fine. Any workaround? Imports System.Threading Public Class Form1 Dim mythread1 As Thread Dim mythread2 As Thread Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load mythread1 = New Thread(AddressOf mysub1) mythread2 = New Thread(AddressOf mysub2) mythread1.IsBackground = True mythread2.IsBackground = True mythread1.Start() mythread2.Start() End Sub Public Sub mysub1() Dim HTML As String WebBrowser1.Navigate("about:blank") mythread1.Abort() End Sub Public Sub mysub2() WebBrowser2.Navigate("about:blank") mythread2.Abort() End Sub

  • ASP.NET MVC submitting json array to controller as regular post request (nonajax)

    - by j3ko
    All the examples of json I can find online only show how to submit json arrays w/ the jquery command $.ajax(). I'm submitting some data from a custom user control as a json array. I was wondering if it's possible to submit a json array as a regular post request to the server (like a normal form) so the browser renders the page returned. Controller: [JsonFilter(Param = "record", JsonDataType = typeof(TitleViewModel))] public ActionResult SaveTitle(TitleViewModel record) { // save the title. return RedirectToAction("Index", new { titleId = tid }); } Javascript: function SaveTitle() { var titledata = GetData(); $.ajax({ url: "/Listing/SaveTitle", type: "POST", data: titledata, contentType: "application/json; charset=utf-8", }); } Which is called from a save button. Everything works fine but the browser stays on the page after submitting. I was thinking of returning some kind of custom xml from the server and do javascript redirect but it seems like a very hacky way of doing things. Any help would be greatly appreciated.

  • How does .NET repaint controls?

    - by serhio
    Say I have a custom Label that I paint in my way. As lite example we have the code: Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) ' MyBase.OnPaint(e) DO NOT USE ' Dim f As Font = Me.Font Dim g As Graphics = e.Graphics Dim textRect As Rectangle = New Rectangle(Me.Location, Me.Size) Using br As New SolidBrush(Me._TextColor) g.DrawString(_Text, f, br, textRect) End Using End Sub maybe this example is useless, because does not bring different behavior that a simple label, but it just for example. Now, the problem is that if this label moves the ancient label area will not be updated, and the old text will remain until the parent will be invalidated. So the question is: How to invalidate the former control region?

  • ASP.Net MVC Ajax form with jQuery validation

    - by Tomas Lycken
    I have an MVC view with a form built with the Ajax.BeginForm() helper method, and I'm trying to validate user input with the jQuery Validation plugin. I get the plugin to highlight the inputs with invalid input data, but despite the invalid input the form is posted to the server. How do I stop this, and make sure that the data is only posted when the form validates? My code The form: <fieldset> <legend>leave a message</legend> <% using (Ajax.BeginForm("Post", new AjaxOptions { UpdateTargetId = "GBPostList", InsertionMode = InsertionMode.InsertBefore, OnSuccess = "getGbPostSuccess", OnFailure = "showFaliure" })) { %> <div class="column" style="width: 230px;"> <p> <label for="Post.Header"> Rubrik</label> <%= Html.TextBox("Post.Header", null, new { @style = "width: 200px;", @class="text required" }) %></p> <p> <label for="Post.Post"> Meddelande</label> <%= Html.TextArea("Post.Post", new { @style = "width: 230px; height: 120px;" }) %></p> </div> <p> <input type="submit" value="OK!" /></p> </fieldset> The JavaScript validation: $(document).ready(function() { // for highlight var elements = $("input[type!='submit'], textarea, select"); elements.focus(function() { $(this).parents('p').addClass('highlight'); }); elements.blur(function() { $(this).parents('p').removeClass('highlight'); }); // for validation $("form").validate(); }); EDIT: As I was getting downvotes for publishing follow-up problems and their solutions in answers, here is also the working validate method... function ajaxValidate() { return $('form').validate({ rules: { "Post.Header": { required: true }, "Post.Post": { required: true, minlength: 3 } }, messages: { "Post.Header": "Please enter a header", "Post.Post": { required: "Please enter a message", minlength: "Your message must be 3 characters long" } } }).form(); }

  • .net bitmap file type limitations

    - by David Archer
    Hi, Given the line: Bitmap bitmap = new Bitmap(stream); where stream is a System.IO.Stream, are there any limitations on the image file type e.g png, jpg, gif etc that can be handled. i.e are all image file/stream header info clear enough to say "I am an image". I haven't run into any yet, but have only being using the pretty standard ones so far. Thanks

  • Powershell in CruiseControl.net to backup existing folder before deploying new version of the code

    - by Rihan Meij
    Hi I would like to zip a bunch of files (.exe and .dll) before I overwrite them with the new build. Is there a simple way to zip files without using some sort of dll? Just creating a folder with the build number / date time stamp will also work great. How do I pass parameters from the cruise control build process into my Powershell script that will do the work then? Is this a sustainable way to do things? Thanks

  • ASP.NET MVC Viewmodel trouble...

    - by ile
    I've already started similar topic, but still didn't find final solution... So here I am with new one :) ... I'm developing NerdDinner from scratch and now I came to point where I define DinnerViewModel. Following these instructions (starting from Listing 5) I came to this: namespace Nerd.Controllers { // View Model Classes public class DinnerViewModel { public DinnerViewModel(List<Dinner> dinners) { this.Dinners = dinners; } public List<Dinner> Dinners { get; private set; } } public class DinnerController : Controller { private DinnerRepository dinnerRepository = new DinnerRepository(); .... public ActionResult NewDinners() { // Create list of products var dinners = new List<Dinner>(); dinners.Add(new Dinner(/*Something to add*/)); // Return view return View(new DinnerViewModel(dinners)); } } } Also, the Dinner table in this new version of NerdDinner is a bit shortened (it contains of DinnerID, Title, EventDate and Description fields). No matter what I try to add here dinners.Add(new Dinner(/*Something to add*/)); I always get following error Error 1 'Nerd.Model.Dinner' does not contain a constructor that takes '1' arguments C:\Documents and Settings\ilija\My Documents\Visual Studio 2008\Projects\Nerd\Nerd\Controllers\DinnerController.cs 150 25 Nerd Because I'm total beginner in C# and generally OOP, I have no idea what to do here... I suppose I need to declare a constructor, but how and where exactly? Thanks, Ile

  • ASP.NET UserControl not defined?

    - by BryanG
    I've just inherited an app that utilizes usercontrols in a couple ways which I'm not too familiar with. The problem I have right now is that when I attempt to publish this code base, I get a few errors which boil down to where some referenced usercontrols are not defined. Here's an example of one line: Private clientControl As New ASP.usercontrols_clientcontrol_ascx This is a tab strip usercontrol which references other usercontrols to dynamically create the tabs. Now, on the surface I get what is going on here...but the compiler is not accepting this. This tab strip usercontrol is in the root of the project, and the other usercontrols are in a sub folder. error BC30002: Type 'ASP.usercontrols_clientcontrol_ascx' is not defined. I'm sure this is 101 stuff here, but the build works and the publish fails. Any direction would be appreciated.

  • Conditional skin file in ASP.Net Theme based off of browser

    - by Dan Appleyard
    Is there a way to use a skin file in a theme only when a certain browser is used? The theme stays the same, I just want skin A to apply when a certain browser is used, and skin B when another browser is used. I know I can have server-side code to check and then set the SkinId of the control to either or, but is there another, more global way? Thanks

  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

  • testing the controller in asp.net mvc

    - by csetzkorn
    Hi, I would like to test the validation of submitted DTO. This is the bare bone of a controller create action: [AcceptVerbs(HttpVerbs.Post)] public RedirectToRouteResult Create(SomeDTO SomeDTO) { SomeObject SomeObject = null; try { SomeObject = this.RepositoryService.getSomeObjectRepository().Create(SomeDTO, this.RepositoryService); } catch (BrokenRulesException ex) { ex.AddModelStateErrors(ModelState, "Model"); } catch (Exception e) { ModelState.AddModelError("Exception", e.Message); } TempData["ViewData"] = ViewData; TempData["SomeDTO "] = SomeDTO; return ModelState.IsValid ? RedirectToAction("SomeObjectDetail", new { Id = SomeObject.Id }) : RedirectToAction("Form"); } The mechanics , although not relevant, is as follows: I have a strongly typed view = form which submits a dto to this action which either returns the form or the details page of the created object. I would like to unit test whether the Model contains certain key/errorMessage combinations given some invalid dto. Did someone do similar stuff? Any pointers would be very much appreciated. Thanks. Best wishes, Christian
