Getting started with TypeScript

TypeScript is an open-source programming language developed and maintained by Microsoft.

TypeScript adds Type support to JavaScript, which makes sure type checking is done resulting in fewer bugs, adds autocomplete supports in the TypeScript editor, supports Object Orientation and structuring and packing of the code, etc.

The code written in TypeScript transpiles to JavaScript by TSC i.e. TypeScript Compiler.

The easiest way to install TSC is to install it as a Node.js package using NPM i.e. Node Package Manager at the command line.

Download and install Node.js first if it is not already installed.

Make sure to include Node.js runtime and npm package manager.

Now to install TSC, open the terminal and type the below command

npm install -g typescript

g makes sure that it is installed globally and not just in the directory from which we are running the command.

There are different editors available for TypeScript

Let us see how to configure TypeScript for Visual Studio Code.

Download link for Visual Studio Code (if not already installed)

Open Visual Studio Code and select the working folder or

in Node.js command prompt, create the directory and open the visual studio code from there

From file explorer in Visual Studio Code, create the new .ts file

Create the typescript file with the extension .ts and add the JavaScript code

To compile the TypeScript code, open the integrated Terminal in Visual Studio Code and type

tsc <<FileName.js>>

This creates a new corresponding JavaScript file for the TypeScript file.

To run it use the node command

node <<filename>>

We can also modify the TypeScript compiler’s default behavior by adding tsconfig.json.

Here we have added tsconfig.json file in the project with the following code

Check below link for different compilerOptions

To configure the build, execute Run Build Task…

As we have created the tsconfig.json file earlier, we will be presented with the following option

Select tsc: build to run the build task.

If tsc: watch is selected the compiler will watch for the changes in TypeScript files and runs the transpiler whenever the changes are saved.

To set the build or watch task as default, select Configure Default Build Task from the Terminal menu.

On selecting tsc: build task, tasks.json file is added inside .vscode

This sets build task as default, so now when we run the Run Build Task, we are not prompted to select a task.

This completes the basic environment setup for using TypeScript with Visual Studio Code.

How to – Showing Total in Footer in jqGrid.


We recently had a requirement to show total for 2 of our decimal columns in jqGrid.

We need to set the following properties footerrow and userDataOnFooter and the a function on loadComplete of grid

Hope it helps..


Fixed – Grid can not be used in this (‘quirks’) model in jqGrid

We got the above error in an HTML Web Resource which was using jqGrid. The page was working fine in IE 10 browser only in IE 8 we got that error.

The solution was to use the following meta tag inside the HEAD tag of the html page.


More details on this meta tag

Hope it helps.

Fixed – Expected identifier, string or number error in HTML Web Resource in IE.

We recently developed an html web resource which was using jqGrid. The web resource was working properly on machines having IE 10 browser, but got the above error in case of IE 8.

As it turned out extra “,” i.e. trailing comma was the reason for the error.

Removing it fixed the issue. IE 10 was more forgiving.

Hope it helps.

‘_formHierarchy’ is undefined error in CRM 2011


We recently faced this issue while opening one of our entity’s form.

This issues comes if we have specified bracket while defining JavaScript function on form.

For e.g. CheckFinancialStatus()

Changing it back to
CheckFinancialStatus resolved the issue.

Hope this helps.

Sample JavaScript Code to retrieve all the members of a Static Marketing List in CRM 2011


We recently had a requirement to retrieve all the members of a particular static marketing list through Jscript. The difficult part was to fetch all the records in case of more than 5000 records. Here we had to repeatedly check the soap result to see if there are any more records and if so create the fetch xml query in runtime and again execute it till we get all the members.

This particular post was of immense help

// call this function and pass the id of the static marketing list to it
 function GetAllMembers(listGuid)

 _sOrgName = "";
 memberArray = new Array();
 morePages = 'true';
 pageNumber = 1;
 pageCookie = '';

 context = typeof (Xrm) == "undefined" ? GetGlobalContext() : Xrm.Page.context;
 var _sServerUrl = context.getServerUrl();
 if (_sServerUrl.match(/\/$/)) {
 _sServerUrl= _sServerUrl.substring(0, serverUrl.length - 1);



function GetMarketingListMembers(listGuid) {

 fetchOnLoad(pageNumber, pageCookie, listGuid);

for (var i = 0; i < memberArray.length; i++) {

 // Iterates over numeric indexes from 0 to 5, as everyone expects

function fetchOnLoad(pageNumber, pageCookie, listGuid) {

 recordGuid = listGuid;

var sFetch = "<fetch mapping='logical' page='" + pageNumber + "' count='5000' paging-cookie='" + pageCookie + "' version='1.0'>" +
 "<entity name='listmember'>" +
 "<attribute name='entityid' />" +
 "<filter>" +
 "<condition attribute='listid' operator='eq' value='" + recordGuid + "' />" +
 "</filter>" +
 "</entity>" +

_oService = new FetchUtil(_sOrgName, _sServerUrl);
 _oService.Fetch(sFetch, myCallBack);

 function myCallBack(results) {

// add all the member in the array

for (i in results) {

if (morePages == 'true') {
 fetchOnLoad(pageNumber, pageCookie, recordGuid);


function FetchUtil(sOrg, sServer) { = sOrg;
 this.server = sServer;
