 Step 1.


Step 2.

Step 3.

Let me explain the scenario…

Suppose we have City Lookup on Lead entity and we want to populate Region (Lookup), State (Lookup) and Zone (Lookup) on selection of particular City from City Lookup. You need to write below code on OnChange event of City Lookup field.

if(crmForm.all.new_cityid.DataValue !=null)

{

    var citylookupValues = crmForm.all.new_cityid.DataValue;

    if(citylookupValues[0] !=null)

    {

        var cityID = citylookupValues[0].id;

        var regionID = GetAttributeValueFromID(“new_city”, cityID , “new_regionid”);

        var stateID = GetAttributeValueFromID(“new_city”, cityID , “new_stateid”);

        var zoneID = GetAttributeValueFromID(“new_region”, regionID , “new_zoneid”);   

        if(regionID != null)

        {

            //Create an array to set as the DataValue for the lookup control.

            var regionlookupData = new Array();

            //Create an Object add to the array.

            var regionlookupItem= new Object();

            //Set the id, typename, and name properties to the object.

            regionlookupItem.id = regionID;

            regionlookupItem.typename = ‘new_region’;

            regionlookupItem.name = regionName;

            // Add the object to the array.

            regionlookupData[0] = regionlookupItem;

            // Set the value of the lookup field to the value of the array.

            crmForm.all.new_regionid.DataValue = regionlookupData;

            crmForm.all.new_regionid.ForceSubmit = true;

 

        }

        if(stateID != null)

        {

            //Create an array to set as the DataValue for the lookup control.

            var statelookupData = new Array();

            //Create an Object add to the array.

            var statelookupItem = new Object();

            //Set the id, typename, and name properties to the object.

            statelookupItem.id = stateID;

            statelookupItem.typename = ‘new_state’;

            statelookupItem.name = stateName;

            // Add the object to the array.

            statelookupData[0] = statelookupItem;

            // Set the value of the lookup field to the value of the array.

            crmForm.all.new_stateid.DataValue = statelookupData;

            crmForm.all.new_stateid.ForceSubmit = true;

        }

        if(zoneID != null)

        {

            var zoneName = GetAttributeValueFromID(“new_zone”, zoneID, “new_name”);

            //Create an array to set as the DataValue for the lookup control.

            var zonelookupData = new Array();

            //Create an Object add to the array.

            var zonelookupItem = new Object();

            //Set the id, typename, and name properties to the object.

            zonelookupItem.id = zoneID;

            zonelookupItem.typename = ‘new_zone’;

            zonelookupItem.name = zoneName;

            // Add the object to the array.

            zonelookupData[0] = zonelookupItem;

            // Set the value of the lookup field to the value of the array.

            crmForm.all.new_zoneid.DataValue = zonelookupData;

            crmForm.all.new_zoneid.ForceSubmit = true;

        }

     }

CrmDiscovery service is a global installable level service that allow the caller to determine the correct organization and URL for his/her need.

Below example show how to create and configure CrmDiscoveryService Web Service proxy.

 

// Create and configure the CrmDiscoveryService Web service

proxy.

CrmDiscoveryService discoveryService = new

CrmDiscoveryService();

discoveryService.UseDefaultCredentials = true;

discoveryService.Url

user belongs to.

RetrieveOrganizationsResponse orgResponse =

(RetrieveOrganizationsResponse)discoveryService.Execute(org

Request);

// Locate the target organization in the list.

foreach (OrganizationDetail orgDetail in

orgResponse.OrganizationDetails)

{

if

(orgDetail.OrganizationName.Equals(“AdventureWorksCycle”))

{

orgInfo = orgDetail;

break;

}

}

// Check whether a matching organization was not found.

if (orgInfo == null)

throw new Exception(“The specified organization was not

found.”);

 


Here we will be calling the default helloworld webservice that is already created for us when we open a asp.net webservice project template in Visual Studio.

We’ll just have a textbox(html control) which will display us the Hello World! response returned from the web service.

This is the step we need to follow

1) Create a new ASP.NET WebApplication

2) Put a html textbox control on the form

<input type=”text” id=”info”/>

3) Put this script code in the head section of the aspx page

<script language=”javascript”>

var xmlHttp;

function getMessage()

{

xmlHttp=new ActiveXObject(”Microsoft.XMLHTTP”);

xmlHttp.open(”post”, “http://localhost/WebService1/Service1.asmx/HelloWorld”, false);

xmlHttp.onreadystatechange=doUpdate;

xmlHttp.send();

return false;

}

function doUpdate()

{

if(xmlHttp.readyState==4)

{

var startTag = “<string xmlns=\”http://tempuri.org/\”>”;

var endTag = “</string>”;

var exch;

var valueStart = 0;

var valueEnd = 0;

valueStart = xmlHttp.responseXML.xml.indexOf(startTag, valueEnd) + startTag.length;

valueEnd = xmlHttp.responseXml.xml.indexOf(endTag, valueEnd+1);

exch = xmlHttp.responseXML.xml.substring(valueStart, valueEnd);

document.forms[0].elements[‘Info’].value=exch;

}

 

</script>

4) Call the getMessage function in the body’s onLoad eventHandler

<BODY onload=”getMessage()”>

5) Run the applicaton. We’ll see the HelloWorld! text in our textbox(’info’)

Now let us understand what is happening inside the javascript code

xmlHttp=new ActiveXObject(”Microsoft.XMLHTTP”)

This line of code creates the XMLHttpRequest object. This object sends request to the server and processes the responses from it.

The above code creates the object specific to Internet Explorer( <=6.o).

It is implemented as Active X for IE. However in IE 7 XMLHttpRequest will come as native JavaScript object.

For other browsers we can write

xmlHttp=new XMLHttpRequest();

or best we can write this

if(window.ActiveXObject)

{

xmlHttp=new ActiveXObject(”Microsoft.XMLHTTP”);

}

else if (window.XmlHttpRequest)

{

xmlHttp=new XMLHttpRequest();

}

 

xmlHttp.open(”post”, “http://localhost/WebService1/Service1.asmx/HelloWorld”, false);

The open method initializes the connection to the server and informs the xmlHttp object how to connect to the server.

post- it indicates how we want to send the data. It can be “get” as well

url- comes the url where we are connecting

false- this means we are making a synchronous call. To make asychronous call simply set it to true

xmlHttp.onreadystatechange=doUpdate;

This specifies the name of the function to be called whenever the state of the xmlHttpRequest changes

xmlHttp.send();

Send method than makes the request to server. This method would return immediately in case of asynchronous call and it would block until the synchronous response is received from the server.

if(xmlHttp.readyState==4)

It tells about the current state of the request

0- uninitialized

1- loading

2- loaded

3-interactive

4-complete

xmlHttp.responseXML.xml

It returns the current response from server in XML=

<?xml version=”1.0″?>

<string xmlns=”http://tempuri.org/”>Hello World !</string>

Than we are using some javascript functions to get the Hello World! and remove everything else.

document.forms[0].elements[‘Info’].value=exch;

Finally assigning the value to our textBox.

The function doUpdate() can be written differently so that we don’t have to make use of any string functions.

function doUpdate()

{

if(xmlHttp.readyState==4)

{

// Here the server is returning us XML in response so we can make use of responseXML

// Here the browser creates a DOM tree to represent that XML and puts a reference to that DOM tree

// in the request’s (xmlHttp) object’s responseXML

var xmlDoc=xmlHttp.responseXML;

var responseElement=xmlDoc.getElementsByTagName(”string”)[0];

var respText=responseElement.firstChild.nodeValue;

document.forms[0].elements[‘Info’].value=respText;

}
