  • Searching major search engines with text such as <%#

    - by Daniel Dyson
    If I type '<%# vs <%"' into any of the major search engines, everything is stripped out except the 'vs'. I understand why they do this. I would just like to know if anyone knows of a way to escape illegal characters so that they are searched properly. I know this is not strictly a programming question, but it is relevant.

  • ASP.NET make a panel visible on click of hyperlink (whilst also cuasing postback for page navigation

    - by Helen
    I may be asking the impossible but let me set out my problem: I have a menu in a MasterPage which uses images and mouseover mouseout events for design purposes. On one of the menu options I need to display a set of sub menus options on the click of the parent menu item. The menu item itself also needs to navigate to a specified url. I was originally trying to use an AJAX accordion panel but as I only had one accordion panel it was always displaying the sub menu items and was not collapsing. I have also tried putting the options in a div and setting the display via javascript. This worked but then was overwritten once the page navigation postback occurred.

  • Package and Publish Web Sites with TFS 2010 Build Server

    - by jdanforth
    To package and publish web sites with TFS 2010 Build Server, you can use MSDeploy and some of the new MSBuild arguments. For example: /p:DeployOnBuild=True /p:DeployTarget=MsDeployPublish /p:MSDeployPublishMethod=InProc /p:CreatePackageOnPublish=True /p:DeployIisAppPath="Default Web Site/WebApplication1" /p:MsDeployServiceUrl=localhost Does all the work for you! Unfortunately these arguments are not very well documented, yet. Please feel free comment with pointers to good docs. You can enter these arguments when editing the Build Definition, under the Process tab and the Advanced section: If you’re working with these things, I’m sure you’ve not missed the PDC 2009 presentation by Vishal Joshi about MS Deploy. A few links on the topic: http://stackoverflow.com/questions/2636153/where-is-the-documentation-for-msbuild-arguments-to-run-msdeploy http://blogs.msdn.com/aspnetue/archive/2010/03/05/automated-deployment-in-asp-net-4-frequently-asked-questions.aspx http://www.hanselman.com/blog/WebDeploymentMadeAwesomeIfYoureUsingXCopyYoureDoingItWrong.aspx

  • NuGet, ASP.Net MVC and WebMatrix - DB Coders Cafe - March 1st, 2011 With Sam Abraham

    - by Sam Abraham
    I am scheduled to share on NuGet (http://nuget.codeplex.com/) at the Deerfield Beach Coder’s Café on March 1st, 2011. My goal for this talk is to present demos and content covering how to leverage this new neat utility to easily “package” .Net-based binaries or tools and share them with others, who in-turn, can just as easy reference and readily use that same package in their Visual Studio 2010 .Net projects. Scott Hanselman has recently blogged in great detail on creating NuGet packages. For hosting a local NuGet package repository, Jon Galloway has a nice article update with a complete PowerShell script to simplify downloading the default feed packages which can be accessed here. Information on my upcoming talk can be found at: http://www.fladotnet.com/Reg.aspx?EventID=514 The following is a brief abstract of the talk: NuGet (formerly known as NuPack) is a free, open source developer focused package management system for the .NET platform intent on simplifying the process of incorporating third party libraries into a .NET application during development. NuGet is a member of the ASP.NET Gallery in the Outercurve Foundation. In this session we will: Discuss the concept, vision and goal behind NuGet See NuGet in action within an ASP.Net MVC project Look at the NuGet integration in Microsoft WebMatrix Create a NuGet package for our demo library Explore the NuGet Project site Configure a NuGet package feed for a local network Solicit attendees input and feedback on the tool  Look forward to meeting you all there. --Sam

  • So what are zones really?

    - by Bertrand Le Roy
    There is a (not so) particular kind of shape in Orchard: zones. Functionally, zones are places where other shapes can render. There are top-level zones, the ones defined on Layout, where widgets typically go, and there are local zones that can be defined anywhere. These local zones are what you target in placement.info. Creating a zone is easy because it really is just an empty shape. Most themes include a helper for it: Func<dynamic, dynamic> Zone = x => Display(x); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } With this helper, you can create a zone by simply writing: @Zone(Model.Header) .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Let's deconstruct what's happening here with that weird Lambda. In the Layout template where we are working, the Model is the Layout shape itself, so Model.Header is really creating a new Header shape under Layout, or getting a reference to it if it already exists. The Zone function is then called on that object, which is equivalent to calling Display. In other words, you could have just written the following to get the exact same effect: @Display(Model.Header) The Zone helper function only exists to make the intent very explicit. Now here's something interesting: while this works in the Layout template, you can also make it work from any deeper-nested template and still create top-level zones. The difference is that wherever you are, Model is not the layout anymore so you need to access it in a different way: @Display(WorkContext.Layout.Header) This is still doing the exact same thing as above. One thing to know is that for top-level zones to be usable from the widget editing UI, you need one more thing, which is to specify it in the theme's manifest: Name: Contoso Author: The Orchard Team Description: A subtle and simple CMS themeVersion: 1.1 Tags: business, cms, modern, simple, subtle, product, service Website: http://www.orchardproject.net Zones: Header, Navigation, HomeFeaturedImage, HomeFeaturedHeadline, Messages, Content, ContentAside, TripelFirst, TripelSecond, TripelThird, Footer Local zones are just ordinary shapes like global zones, the only difference being that they are created on a deeper shape than layout. For example, in Content.cshtml, you can find our good old code fro creating a header zone: @Display(Model.Header) The difference here is that Model is no longer the Layout shape, so that zone will be local. The name of that local zone is what you specify in placement.info, for example: <Place Parts_Common_Metadata_Summary="Header:1"/> Now here's the really interesting part: zones do not even know that they are zones, and in fact any shape can be substituted. That means that if you want to add new shapes to the shape that some part has been emitting from its driver for example, you can absolutely do that. And because zones are so barebones as shapes go, they can be created the first time they are accessed. This is what enables us to add shapes into a zone before the code that you would think creates it has even run. For example, in the Layout.cshtml template in TheThemeMachine, the BadgeOfHonor shape is being injected into the Footer zone on line 47, even though that zone will really be "created" on line 168.

  • Find odd and even rows using $.inArray() function when using jQuery Templates

    - by hajan
    In the past period I made series of blogs on ‘jQuery Templates in ASP.NET’ topic. In one of these blogs dealing with jQuery Templates supported tags, I’ve got a question how to create alternating row background. When rendering the template, there is no direct access to the item index. One way is if there is an incremental index in the JSON string, we can use it to solve this. If there is not, then one of the ways to do this is by using the jQuery’s $.inArray() function. - $.inArray(value, array) – similar to JavaScript indexOf() Here is an complete example how to use this in context of jQuery Templates: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server">     <style type="text/css">         #myList { cursor:pointer; }                  .speakerOdd { background-color:Gray; color:White;}         .speaker { background-color:#443344; color:White;}                  .speaker:hover { background-color:White; color:Black;}         .speakerOdd:hover { background-color:White; color:Black;}     </style>     <title>jQuery ASP.NET</title>     <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.min.js" type="text/javascript"></script>     <script src="http://ajax.aspnetcdn.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js" type="text/javascript"></script>     <script language="javascript" type="text/javascript">         var speakers = [             { Name: "Hajan1" },             { Name: "Hajan2" },             { Name: "Hajan3" },             { Name: "Hajan4" },             { Name: "Hajan5" }         ];         $(function () {             $("#myTemplate").tmpl(speakers).appendTo("#myList");         });         function oddOrEven() {             return ($.inArray(this.data, speakers) % 2) ? "speaker" : "speakerOdd";         }     </script>     <script id="myTemplate" type="text/x-jquery-tmpl">         <tr class="${oddOrEven()}">             <td> ${Name}</td>         </tr>     </script> </head> <body>     <table id="myList"></table> </body> </html> So, I have defined stylesheet classes speakerOdd and speaker as well as corresponding :hover styles. Then, you have speakers JSON string containing five items. And what is most important in our case is the oddOrEven function where $.inArray(value, data) is implemented. function oddOrEven() {     return ($.inArray(this.data, speakers) % 2) ? "speaker" : "speakerOdd"; } Remark: The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0. From http://api.jquery.com/jQuery.inArray/ So, now we can call oddOrEven function from inside our jQuery Template in the following way: <script id="myTemplate" type="text/x-jquery-tmpl">     <tr class="${oddOrEven()}">         <td> ${Name}</td>     </tr> </script> And the result is I hope you like it.

  • When and How is an image cached for an ASPX with ContentType = image/jpeg ?

    - by Aamir Hasan
     In asp.net you can cache your page. You can vary the output cache by the followingThe query string in an initial request (HTTP GET).Control values passed on postback (HTTP POST values).The HTTP headers passed with a request.The major version number of the browser making the request.      A custom string in the page. In that case, you create custom code in the Global.asax file to specify the page's caching behavior.Link: http://msdn2.microsoft.com/en-us/library/xadzbzd6(VS.80).aspxyou can set the output caching for your GetImage.aspx, so that you dont have to requery the database every image request ,but you must use varybyParam , so that you have a cached version for every parameters arrangement:set the output cache for your page like this :At top of ASPX page: <%@ OutputCache Duration="600" VaryByParam="ID,Height,Width" %>VaryByParam  attribute allows you to vary the cached output depending on the query string.Adding this will make your images cached for 600 seconds, so that if the image request within this period ,the cahed version will be returned
