"The Ribbon Tab with id: "Ribbon.Read" has not been made available for this page or does not exist. Use Ribbon.MakeTabAvailable()"


Have you come acrossthis error on your page?
Then don't worry. its not your fault but a riddle left by MSFT. 
I know that you got this error when playing with wiki pages. Yes, if wiki pages are rendered in IFrame (SPModalDialogue) or wiki page url has IsDlg=1(as part of querystring) this error shows up in sharepoint logs. 
Solution:
You can simply fix this by changing the type of the page from wiki to webpart page.

The steps going to be easy and I will demonstrate along with screenshots and examples with the Google PostMan RESTClient . I have explained the steps below which follows the OAuth 2.0 protocol. All the steps are straight forward, but constructing the URLs are little tricky!

SharePoint 2013 REST API Reference

SharePoint 2013 introduces a Representational State Transfer (REST) interface that opens the SharePoint 2013 development platform to standard Web technologies and languages. These comparable to the existing SharePoint   client object models . Now, developers can interact remotely with SharePoint data by using any technology that supports REST web requests. This means that developers can perform   Create ,   Read ,   Update , and   Delete   (CRUD) operations from their apps for SharePoint, solutions, and client applications, using REST web technologies and standard Open Data Protocol (OData) syntax. Reference Sample REST endpoint: http://server/site/_api/lists/getbytitle('listname') the above api gets the List ‘listname’, by the method ‘getbytitle’.     Before it can do anything with SharePoint, your remote Web or mobile application must obtain authorized access. One of the approach would be using Oauth. The MSDN Library...

Simple Risk Assessment Matrix table with resultant risk calculation

-
Image
This post is not related to SharePoint and can be used in any web application with simple html and Jquery. I was preparing a risk matrix table for one of my projects and thought it is worth sharing it here. " A Risk Assessment Matrix is a project management tool that allows a quick view of the probable risks evaluated in terms of the likelihood or probability of the risk and the severity of the consequences. " . Let us build the below table. Once you have the page ready, you can calculate the resultant risk by passing the likelihood and the severity to the page using query-strings. For example your page is riskMatrix.html, then: http://mySitename/pages/riskMatrix.html?L=2&S=3 , so here Likelihood=3 and Severity=3, so the resultant risk is highlighted as M. Below is the complete code HTML, CSS and JS. Make sure you have referenced bootstrap and jquery (offline copy/CDN) in your page. <table class="table table-bordered table-responsive...

Kendo UI (Core JavaScript)  grid Server Paging, Server Sorting and Server Filtering with Dynamic SQL queries Introduction Writing this post after a long time. Came across Kendo UI components in one of the projects. Kendo UI Grid (paid!) is one of the amazing html components from Kendo with excellent features like filtering, sorting, grouping, re-arranging, paging etc. Problem I recently came across a requirement where I had to pull data from MSSQL server and display it on a kendo grid. But it was about pulling thousands of records to the grid, which would slow down the app for the first time, but I did not want that to happen. So thought of implementing kendo Server paging which is readily available with Kendo Grid. But since I use Kendo UI core pure JavaScript framework and not the kendo wrapper for asp.net mvc etc, paging, filtering and sorting need to be handled manually by the developer. After Googling for a while, I did not find any help relevant to implementati...

As you know in SharePoint , ribbon button images are coming from a built in image called formatmap32x32.png and formatmap16x16.png which are located at: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\1033\IMAGES So if you are creating custom ribbon buttons, and if you want to use one of the built in button image, then how would you set Image32by32Top and Image32by32Left ? Here is the answer. Get the image from from the above path. Choose the icon image which you would like yo use. As shown below, say the icon which chose is a pie chart as marked with black outline. Count its position from top. its 7. also count its position from left, its 8.  Since the image is 32*32, you would calculate as left=32*8= 256 and Top=224. Now in your Elements.xml use this counts as: Image32by32="/_layouts/$Resources:core,Language;/images/formatmap32x32.png" Image32by32Top="-224" Image32by32Left="-256" Use the similar s...
