WCF Services : System.ServiceModel(serviceBehaviors and bindings) settings for Http and Https.

Goal

When a WCF service is converted from HTTP to HTTPS the service stops working. Here are the web.config settings. Which can fix the issue.

[KnockOut.js]Sample code to for beginners.

Goal

The blog is to create a working form using KnockOut.js, generic handler(ashx) and JQuery. This is strictly for beginners, who want to use KnockOut.js. I am not giving any solution in this blog, this is just a starting thread for the people who are still having trouble using KnockOut.

Steps

  1. Create a visual studio project. I have named the solution as Sample and project name is Sample.KnockOut.
  2. Tools > NuGet Package Manager > Package Manager Console > Run "Install-Package knockoutjs" (CLICK HERE)
  3. Tools > NuGet Package Manager > Package Manager Console > Run "Install-Package jQuery" (CLICK HERE)
  4. Add the files which are shown in the Solution Explorer image below and use the code which is mentioned in the blog.

Create virtual directories and application pools using PowerShell scripts

Purpose

This script will create an application pool if its does not exists and a virtual directory for the site using PowerShell.

Scenario

Suppose we have a website(in this case we have test.maulikdhorajia.com). And we have to create 100 virtual directories in the same website with same structure. But some Virtual Directories are already there and some needs to be created. Some of them uses framework 2.0 and some 4.0. Some of them are having 32 bit enabled and some of them don't need it. Using this script we can do it with saving a lot of time in doing manual process.

### Author : Maulik Dhorajia
### Purpose : This script will create an application pool if its doesnot exists and will create a virtual directory for the site using PowerShell.

# IMPORT WebAdministration Module

Filter OOTB SharePoint ListView web part using IWebPartRow connection Interface and WebControl.

Related Blog

In one of my old blogs I tried to explain the similar thing(Filter OOTB SharePoint ListView web part using IWebPartRow connection Interface.). The purpose of that blog was just show a simple way of using the IWebPartRow connection and a ListView WebPart.

Goal

In the current blog we will try and filter ListView WebPart using Connection object in IWebPartRow. Also there will be a RadioButtonList using which we can drill down the filter.

Create a custom list

  1. Site Actions > View All Site Content
  2. Create new List
  3. Custom List
  4. Name the list "Sample".
  5. Visit list settings and add new column "Year".
  6. Add a few sample data.
  7. Alter the "All Items" and add ID in the view.
  8. Now the list will look like below given image.

Web part for Conncetion

  1. Open Visual Stuido 2010
  2. Create new project
  3. Select "Web Part". Don't mistake using "Visual Web Part".
  4. Rename the WebPart1 to "SampleConnection".
  5. Use the below given code to be used as a sample.
#region System

How to use?

  1. SharePoint Site > Edit a page.
  2. Click "Add a Web Part".
  3. Top ribbon > List and Libraries > Select "Sample".
  4. Again Click "Add a Web Part".
  5. Top ribbon > Custom > Select "SampleConnection" web part.
  6. The screen will have now 2 Web Parts. Check out the below given image.
  7. This happens in Edit Mode of page only, so make sure the page is in Edit Mode. Have a look at the image below to select a connection web part.
  8. A box will popup to to select a filter. I will select Year. Click "Finish".
  9. Now to test this stuff. Select the year from the Year from the "Sample Connection" web part.

  10. So this was if a ListView needs filter. If we want to remove it. Just go through step 7 and click "Remove Connection" from the popup box. And the screen will be back to as it was.

Sharepoint 2010 - Strange blog URL issue with site using Variations(Multilingual site). - REALLY WEIRD ISSUE!

Scenario/Symptoms

  • We have a site with variations. English/Spanish
  • Structure
    • Main Site > en > English Blog(Add 1 or 2 sample blogs)
    • Main Site > es > Spanish Blog(Add 1 or 2 sample blogs)
  • On the "Main Site" we added a "Content Query Web Part". Apply the below given setting.
  • Click on the link of any English blog. IT WORKS FINE!!!
  • Now click on the Spanish blog link. IT SAYS "PAGE NOT FOUND"!!!
  • Another way to get this is.
    • Go to the URL of Spanish blog site.
    • You can find the blogs on the page.
    • Click on the blog link IT SAYS "PAGE NOT FOUND"!!!.
    • Or navigate to "Administrar entradas de blog"(AllPosts.aspx). This page will show all the blogs in the list. Click on the blog link IT SAYS "PAGE NOT FOUND"!!!


Cause

We added a column to the list "Post". Now this small thing was causing the whole havoc.


Solution

There are 3 ways to
  1. Either don't add any column to list "Post". => BAD ONE
  2. Copy SharePoint Designer > Lists > Estrada De Blog and paste it there with name "Post". Don't delete the folder. Just need to duplicate and rename the folder.
  3. Read the blog => Sharepoint 2010 - Solution to blog URL issue with site using Variations(Multilingual site) to see the feature stapler solution for this issue.


Hope this helps. If you have any questions or a better solution, I am all open for it. Thanks for reading the blog.
