  • ASP.NET CompositeControl with child controls that contain children

    - by tomfanning
    I am building an ASP.NET server control which extends CompositeControl. I need fine grained control over the rendering, so I override Render() and output the child controls myself, interspersed with HTML generation code: writer.AddStyleAttribute("float", "left"); writer.RenderBeginTag(System.Web.UI.HtmlTextWriterTag.Div); writer.RenderBeginTag(System.Web.UI.HtmlTextWriterTag.Strong); writer.Write("Table"); writer.RenderEndTag(); // strong writer.WriteBreak(); tableList.RenderControl(writer); writer.RenderEndTag(); // div This works really well for user controls that just contain simple controls without children of their own. However, if I want to use something like a MultiView or an UpdatePanel I run into problems, since I can't override Render() on View or UpdatePanel without extending them, and if I do extend them the implementation would presumably have to depend on FindControl() voodoo to get references to the right controls during render. That doesn't sound like the right way to do this - is there a better way?

  • ASP.NET MVC Route Contraints with {ID}-{Slug} Format

    - by TimLeung
    I have a route like following, ideally I would like it to match: domain.com/layout/1-slug-is-the-name-of-the-page routes.MapRoute( "Layout", // Route name "layout/{id}-{slug}", // URL with parameters new { controller = "Home", action = "Index", id = @"\d+$" } ); But when I hit the url, I am keep on getting this exception: The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Index(Int32)' in .... The above route will match the following though: domain.com/layout/1-slug or domain.com/layout/1-slug_permalink Seems like the hyphen that separates the ID from the Slug is causing issues.

  • .NET Framework 3.5, Assembly Binding Logging

    - by Achilles
    I am getting the following error: Could not load file or assembly 'System.Web.DynamicData, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. I've researched the problem and some of the solutions are pointing to Turning on Assembly Binding Logging. I'm confused as to what this error is. So my question: *What does this error mean and how do I resolve it? I am not hosting the site in a shared hosting scenario, it is on a single server running .NET Framework 3.5.0 using IIS 6.0 Edit .Net Framework 3.5 SP 1 isn't installed on the server. The missing assemblies are apart of that Service Pack.

    - by ch2o
    I'm migrating a Visual Fox Pro code to C #. NET What makes the Visual Fox Pro: generates a string of 5 digits ("48963") based on a text string (captured in a textbox), if you always enter the same text string will get that string always 5 digits (no reverse), my code in C #.

  • ASP.NET MVC Authentication Cookie Not Being Retrieved

    - by Jamie Wright
    I am having a hard time implementing "Remember Me" functionality in an MVC application with a custom principal. I have boiled it down to ASP.NET not retrieving the authentication cookie for me. I have included a snaphot below from Google Chrome. Shows the results of Request.Cookies that is set within the controller action and placed in ViewData for the view to read. Notice that it is missing the .ASPXAUTH cookie Shows the results from the Chrome developer tools. You can see that .ASPXAUTH is included here. Does anyone know what the issue may be here? Why does ASP.NET not read this value from the cookie collection?

  • set label value in vb.net

    - by julio
    Hi-- I'm usually a PHP guy but got stuck doing a project in vb.net. I have a query (sqldatasource) that returns a single value (the last update date). I want to use a label to say something like "Last updated: " < Label = (returned value) In PHP this would be simple. In vb.net, all I can find are endless badly written code behinds showing how you'd execute the query onLoad then bind it to the label. Is this really the only way to do this? It seems like a ridiculously simple problem to have such a long solution. I have used a datagrid control to just bind the query result directly, but it prints the column name as well as the date, so it's not ideal. Any ideas?

  • Design Time Attribute For CSS Class in ASP.net Custom Server Control

    - by Jon P
    Hopefully some Custom Control Designers/Builders can help I'm attempting to build my first custom control that is essential a client detail collection form. There are to be a series of elements to this form that require various styles applied to them. Ideally I'd like the VS 2005/2008 properties interface to be able to apply the CSSClass as it does at the control level, i.e. with a dropdown list of available CSS Clases. Take for example the Class to be applied to the legend tag /// <summary>Css Class for Legend</summary> [Category("Appearance")] [Browsable(true)] [DefaultValue("")] //I am at a loss as to what goes in [Editor] [Editor(System.Web.UI.CssStyleCollection), typeof(System.Drawing.Design.UITypeEditor))] public string LegendCSSClass { get { return _LegendCSSClass; } set { _LegendCSSClass = value; } } I have tried a couple of options, as you can see from above, without much luck. Hopefully there is something simple I am missing. I'd also be happy for references pertaining to the [Editor] attribute

  • .Net friendly, local, key-value pair, replicatable datastore

    - by Brad Mathews
    I am looking for a key/value type datastore with very specific requirements. Anyone know anything that will work? Needs to be a component of some sort. No additional installation needed. The datastore needs to be on the local hard drive. I am using VB.Net for a desktop app running Windows XP through 7 so it needs to callable by that environment. It needs to replicatable. If I have four copies of my app running on the network, each local copy of the datastore needs to replicate with the others. As close to real time as possible. The first three are easy, I can do that with ADO.Net out of the box. The last one, replication, is the one I do not have answer to. Does such an animal exist? Thanks, Brad

  • In VB.NET how do you specify Inherits/implements on a generic class with multi-constraints

    - by Romel Evans
    When I write the following statement in VB.Net (C# is my normal language), I get an "end of statement expected" referring to the "Implements" statement. <Serializable()> _ <XmlSchemaProvider("EtgSchema")> _ Public Class SerializeableEntity(Of T As {Class, ISerializable, New}) _ Implements IXmlSerializable, ISerializable ... End Class The C# version that I'm trying to emulate is: [Serializable] [XmlSchemaProvider("MySchema")] public class SerializableEntity<T> : IXmlSerializable, ISerializable where T : class, new() { .... } Sometimes I feel like I have 5 thumbs with VB.NET :)

  • ASP.net VB Timers

    - by Tom Gullen
    I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable. In ASP it was easy with the Timer object, but in .net I can't find anything on Google. I need something along the lines of: Dim startTime Dim endTime startTime = now() doBigFunction() endTime = now() response.write("That took " & endTime - startTime & " milliseconds") Cheers!

  • VB.NET function that takes other functions as a parameter, and executes them

    - by rob
    Hello, Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object. As I am calling these, it seems like it should be able to be factored better. For instance, everytime I call any of these functions, I want to test the return value for a session drop, and do something to try and reconnect to the remote system, etc. Using .net 3.5 Thanks! -R

  • 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.

  • Problem running ASP.NET MVC 2 website on IIS7

    - by Charlie
    I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.

  • I would like to convert Joomla CMS to ASP.net as there is no CMS like Joomla in .net. Would that

    - by SIA
    Hello friends I have this idea boggling my head since a long time. As a developer, I get a lot from the community and feel like giving back something to the community. And after knowing and working on Joomla i found Joomla CMS as the most flexible, easy and user friendly cms. As a developer, I like most of the features of it. Now, i want to have a asp.net version of joomla, available free to the community. I wanted to start it from scratch and it would be a copy/same as joomla. Would that be a good idea to go with it? Are there any CMS (same as Joomla) available in asp.net? I would like to have suggestions and advice from my community developers. Critics are welcomed ;) SIA
