  • ASP.Net Problem with Event Handlers and Control Creation Timing

    - by Oliver Weichhold
    What I am trying to achieve here is to display a number of LinkButtons in a RadGrid Column. The buttons are generated from a collection property member of the bound grid row item. The CollectionLinkButton control is nothing more than a asp:Panel derived control that populates its Child Controls from "DataItem.SomeCollection" and this is working fine. The problem I am facing is with this part: Collection='<%# DataBinder.Eval(Container, "DataItem.SomeCollection") %' This is because databound Collection Property is populated so late in the lifecycle of the page that the LinkButton Controls that the CollectionLinkButton class creates from the collection are not available yet during Postback when the Click event Handler is supposed to fire and I have currently no idea how to solve this problem. <radG:RadGrid ID="grid" runat="server" DataSourceID="ds_AB"> <MasterTableView> <Columns> <radG:GridTemplateColumn> <ItemTemplate> <local:CollectionLinkButton ID="LinkButton1" runat="server" CssClass="EntityLinkButton" Collection='<%# DataBinder.Eval(Container, "DataItem.SomeCollection") %>' CollectionProperty="Id" CollectionDisplayProperty="Name" Text='<%# DataBinder.Eval(Container, "DataItem.Name") %>'</local:CollectionLinkButton> </ItemTemplate> </radG:GridTemplateColumn>

    - by dominic
    Hi I am having a problem debugging an issue on a website. Everything works locally, the local and server databases are the same The strange thing about the error is that it points to my local dev machine in the error stack.

  • NetworkStream.Read delay .Net

    - by Gilbes
    I have a class that inherits from TcpClient. In that class I have a method to process responses. In that method I call I get the NetworkStream with MyBase.GetStream and call Read on it. This works fine, excpet the first call to read blocks too long. And by too long I mean that the socket has recieved plenty of data, but won't read it until some arbitrary limit is reached. I can see that it has recieved plenty of data using the packet sniffer WireShark. I have set the recieve buffer to small amounts, and very small amounts (like just a few bytes) to no avail. I have done the same with the buffer byte array I pass to the read method, and it still delays. Or to put it another way. I am download 600k. The download takes 5 seconds (at a little over 100k/second connection to the server which makes sense). The initial Read call takes 2-3 seconds and tells me only 256 bytes are availble (256 is the Recieve buffer and the size of the array I read in to). Then magically, the other few hundred thousand bytes can be read in 256 byte chunks in only a few process ticks each. Using a packet sniffer, I know that during those initial 2-3 seconds, the socket has recieved much more than just 256 bytes. My connection wasn't .25k/second for 3 seconds and then 400k for 2 seconds. How do I get the bytes from a socket as they come in?

  • Copy EXIF Metadata from TIF to JPEG in C# / VB.NET

    - by George
    Hello! I would really appreciate if you could shed light on this problem. I have 2 images, one was created from TIF file with metadata, the other is an in-memory image that will be saved as jpeg. Then I use this routine to transfer exif metadata from first image to the second one (that is from the one created from tif file to the in-memory image): For Each _p In image1.PropertyItems image2.SetPropertyItem(_p) Next And this works perfectly fine. All exif items are successfully copied. I confirmed this by using watches in debug mode. The problem comes when you save image2 as jpeg using this: Dim eps As EncoderParameters = New EncoderParameters(1) eps.Param(0) = New EncoderParameter(Encoder.Quality, 85) Dim ici As ImageCodecInfo = GetEncoderInfo("image/jpeg") image2.Save("C:\1.jpg", ici, eps) Only very few EXIF properties are saved with image2 jpeg file however, namely only camera model and camera maker. However If I save image2 as TIF, all properties from the original tif will be there. Can anyone explain why is that? Thanks.

  • ASP.NET MVC unit testing

    - by Simon Lomax
    Hi, I'm getting started with unit testing and trying to do some TDD. I've read a fair bit about the subject and written a few tests. I just want to know if the following is the right approach. I want to add the usual "contact us" facility on my web site. You know the thing, the user fills out a form with their email address, enters a brief message and hits a button to post the form back. The model binders do their stuff and my action method accepts the posted data as a model. The action method would then parse the model and use smtp to send an email to the web site administrator infoming him/her that somebody filled out the contact form on their site. Now for the question .... In order to test this, would I be right in creating an interface IDeliver that has a method Send(emailAddress, message) to accept the email address and message body. Implement the inteface in a concrete class and let that class deal with smtp stuff and actually send the mail. If I add the inteface as a parameter to my controller constructor I can then use DI and IoC to inject the concrete class into the controller. But when unit testing I can create a fake or mock version of my IDeliver and do assertions on that. The reason I ask is that I've seen other examples of people generating interfaces for SmtpClient and then mocking that. Is there really any need to go that far or am I not understanding this stuff?

  • ASP.NET MVC download image rather than display in browser

    - by RSolberg
    Rather than displaying a PNG in the browser window, I'd like the action result to trigger the file download dialogue box (you know the open, save as, etc). I can get this to work with the code below using an unknown content type, but the user then has to type in .png at the end of the file name. How can I accomplish this behavior without forcing the user to type in the file extension? public ActionResult DownloadAdTemplate(string pathCode) { var imgPath = Server.MapPath(service.GetTemplatePath(pathCode)); return base.File(imgPath, "application/unknown"); }

  • UI form component for ASP NET MVC

    - by Bugeo
    Hi I'd like to find a component that help me to build input forms in asp MVC. I find that ther are many components (grid, tree, tab...) but not a "Form component". I know that i can use the HTML HELPER (.labelfor(.. .inputTextFor(... ) ..but i don't like to write the html tags around the fields and labels ( ... ) I want that all the form in my application look similar and, if a change is needed i want to make it in one place ( ex in the "FormComponentFactory()" for example ) I created my own FormComponent but i find myself reinvent the wheel..

  • ASP NET MVC custom route fallback

    - by manudea
    I'm wondering if it is possibile to customize routing in a way that all requests are evaluated by a piece of code, redirected to the relevant controller if a match is found or passed to next rout in list if not found. sample request: /my coolpage/another one the code searches and determine that the right controller for this is Page, action is "list" and id is "123" and so redirects another request: /products/list/5 code finds no match al passes it back to next route that knows how to handle it... any idea on how to do this?

  • .NET: How to know when serialization is completed?

    - by Ian Boyd
    When I construct my control (which inherits DataGrid), I add specific rows and columns. This works great at design time. Unfortunately, at runtime I add my rows and columns in the same constructor, but then the DataGrid is serialized (after the constructor runs) adding more rows and columns. After serialization is complete, I need to clear everything and re-initialize the rows and columns. Is there a protected method that I can override to know when the control is done serializing? Of course, I'd prefer to not have to do the work in the constructor, throw it away, and do it again after (potential) serialization. Is there a preferred event that is the equivalent of "set yourself up now", so that it is called once whether I'm serialized or not? The serialization i speak of comes from the InitializeComponent() method in the form's code-behind file. #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { ... } It would have been perfect if InitializeComponent was a virtual method defined by Control, then i could just override it and then perform my processing after i call base: protected override void InitializeComponent() { base.InitializeComponent(); InitializeMe(); } But it's not an ancestor method, it's declared only in the code-behind file. i notice that InitializeComponent calls SuspendLayout and ResumeLayout on various Controls. i thought it could override ResumeLayout, and perform my initialization then: public override void ResumeLayout() { base.ResumeLayout(); InitializeMe(); } But ResumeLayout is not virtual, so that's out. Anymore ideas? i can't be the first person to create a custom control.

  • Check malicious Redirect URL in ASP.NET

    - by acidzombie24
    I heard of sites using other site to redirect users either to their own site or to hide behind another site. In my code i redirect in a few places such as post a comment (its easier to use a return url then figure out the page using data given). How do i check if the return URL is my own url? I think i use absolute paths so i can easily check if the first character is '/' but then i will lose relative flexibility. This also disallows me from doing http://mysite.com/blah in the redirect url. I could patch the url by adding mysite + string but i'll need to figure out if string is a relative url or already a mysite.com url. Whats the easiest way to ensure i am only redirecting to my site?

  • Unit Testing functions within repository interfaces - ASP.net MVC3 & Moq

    - by RawryLions
    I'm getting into writing unit testing and have implemented a nice repository pattern/moq to allow me to test my functions without using "real" data. So far so good.. However.. In my repository interface for "Posts" IPostRepository I have a function: Post getPostByID(int id); I want to be able to test this from my Test class but cannot work out how. So far I am using this pattern for my tests: [SetUp] public void Setup() { mock = new Mock<IPostRepository>(); } [Test] public void someTest() { populate(10); //This populates the mock with 10 fake entries //do test here } In my function "someTest" I want to be able to call/test the function GetPostById. I can find the function with mock.object.getpostbyid but the "object" is null. Any help would be appreciated :) iPostRepository: public interface IPostRepository { IQueryable<Post> Posts {get;} void SavePost(Post post); Post getPostByID(int id); }

  • Separate functionality depending on Role in ASP.NET MVC

    - by Andrew Bullock
    I'm looking for an elegant pattern to solve this problem: I have several user roles in my system, and for many of my controller actions, I need to deal with slightly different data. For example, take /Users/Edit/1 This allows a Moderator to edit a users email address, but Administrators to edit a user's email address and password. I'd like a design for separating the two different bits of action code for the GET and the POST. Solutions I've come up with so far are: Switch inside each method, however this doesn't really help when i want different model arguments on the POST :( Custom controller factory which chooses a UsersController_ForModerators and UsersController_ForAdmins instead of just UsersController from the controller name and current user role Custom action invoker which choose the Edit_ForModerators method in a similar way to above Have an IUsersController and register a different implementation of it in my IoC container as a named instance based on Role Build an implementation of the controller at runtime using Castle DynamicProxy and manipulate the methods to those from role-based implementations Im preferring the named IoC instance route atm as it means all my urls/routing will work seamlessly. Ideas? Suggestions?

  • [ASP.NET] IIS7 downloading file length

    - by GTD
    I've following code for file download: FileInfo fileInfo = new FileInfo(filePath); context.Response.Clear(); context.Response.ContentType = "application/octet-stream"; context.Response.AddHeader("Content-Disposition", "attachment; filename=" + System.IO.Path.GetFileName(filePath)); context.Response.AddHeader("Content-Length", fileInfo.Length.ToString()); context.Response.WriteFile(filePath); context.Response.End(); When I run it on my local IIS6 it works fine. Web browser (tested on IE8, Firefox 3.5.2, Opera 10) shows file length before I start download the file. When I run this code on remote IIS7, web browser doesn't shows file length. File length is unknown. Why I don't get file length when this code runs under IIS7?

  • ASP.NET Loading a User Control in a Repeater

    - by user70192
    Hello, I have a Repeater control that loads instances of a custom control I have built. This repeater looks like this: <asp:Repeater ID="myRepeater" runat="server" OnLoad="myRepeater_Load"> <HeaderTemplate> <table border="0" cellpadding="0" cellspacing="0"> </HeaderTemplate> <ItemTemplate> <tr><td><my:CustomControl ID="myControl" runat="server" OnLoad="myControl_Load" /> </td></tr> </ItemTemplate> <FooterTemplate> </table> </FooterTemplate> </asp:Repeater> I bind to the Repeater through the myRepeater_Load event handler. My custom control is used to render an item within the Repeater. Because of this, I am trying to set properties on the custom control during the myControl_Load event handler. However, I do not know how to access the current item during the myControl_Load event. Is there a way I can pass along the current item or access the current item during the myControl_Load event? If so, how? Thank you,
