Handling images and on the fly re-sizing in DD4T

When it comes with DD4T we have plenty of control on the data and we can decided on how we wanted the page to be rendered. The traditional approach of having difference size of same image is replaced in DD4T to have one single image and generate the thumbnail on the fly. In this approach, we will have only one image published in tridion, and rest will be created on the fly based on the request. Just by adding below configuration on the web.config modules session will enable this feature <modules runAllManagedModulesForAllRequests="true">   <add name="BinaryModule"         type="DD4T.Web.Binaries.BinaryDistributionModule" />  </modules> The BinaryDistributionModule process the request as below Process the Binary Request Check if the file is already in the file system. If file is available compare the last published date of the binary against the broker. If the file is updated, update the existing file in the file system....

Navigation in DD4T

There always been a question on What is the best approach for building navigation with DD4T and ASP.NET MVC? Answer is: There is TridionSiteMapProvider as part of the DD4T.Mvc project, which can be used out of the box. The  DD4T.Examples.Templates project also have a example on how Sitemap can be generated from the template ( TBB ) Many organization will have different kinds of navigation structure, It can be from very simple structure or it can be a heavily complex in nature. In this article you can see how the default SitemapProvider can be used and how we could customize to achieve complex Navigations like Megamenu or similar using TridionSiteMapProvider. Setting up the default TridionSiteMapProvider The only configuration you would need to do in web.config is set the your default sitemap provider is as below. <system.web> <siteMap defaultProvider= "TridionSiteMapProvider" enabled= "true" > <providers> <clear/> ...

Dynamic Publication Resolving in DD4T

DD4T is a great framework which would give you everything in place what you basically needed. Here we will see how we could resolve the publication based on the URL,  when we work with multiple publications accessing same web site, our DD4T would need to query dynamically to different publications. Many times it can be based on URL, based on the domain or language we could resolve the publication. It’s obviously up to us how we implement it. By default the DD4T framework queries the publication that we have mapped in the key: <add key="DD4T.PublicationId" value="7" /> or keep it 0 to query all publications We can make it dynamic simply by implementing the IPublicationResolver class Step 1: To resolve publication dynamically, we can write a class that implement DD4T.ContentModel.Contracts.Resolvers.IPublicationResolver namespace Indivirtual.DD4T.Mvc.Resolver { public class SitePublicationResolver : IPublicationResolver { ...
