Rob is a CRM developer in an organization; he comes across a requirement that needs him to deactivate the Contact form if the parent account status is inactive. He figures he can use JavaScript to solve this problem. We will make a Web API call for the account to check its status and then deactivate the form using a JavaScript function.

First, we will retrieve the statuscode field of the parent account. Then, we need to check if the status of the parent is inactive; if yes, then we need to deactivate the form. We will write a JavaScript function for this. The whole process is shown in the following code:

function checkAccountStatus()
{
  //Fetch parent account
  var accountAttribute = Xrm.Page.getAttribute("parentcustomerid");
  var accountId;

  //Check if account is not null
  if (accountAttribute != null)
  {
    //Get value of account attribute
    accountId = accountAttribute.getValue();
    if (accountId != null)
    {
      //Gets the account Id
      accountId = accountId[0].id.replace(/[{}]/g, "");

      //Initializes new request.
      var req = new XMLHttpRequest();
      //Open the request
      req.open("GET", Xrm.Page.context.getClientUrl() + 
      "/api/data/v8.2/accounts(" + accountId + ")?
      $select=name,statuscode", true);
      //Sets the Request Headers
      req.setRequestHeader("OData-MaxVersion", "4.0");
      req.setRequestHeader("OData-Version", "4.0");
      req.setRequestHeader("Accept", "application/json");
      req.setRequestHeader("Content-Type", "application/json; 
      charset=utf-8");
      req.setRequestHeader("Prefer", 
      "odata.include-annotations="*"");
      //Function to detect ready state
      req.onreadystatechange = function ()
      {
        //Check if request is completed
        if (this.readyState === 4)
        {
          req.onreadystatechange = null;

          //Check if status code is 200 for success
          if (this.status === 200)
          {
            var result = JSON.parse(this.response);
            var name = result["name"];
            var statuscode = result["statuscode"];

            //checks if statuscode is inactive i.e 3
            if (statuscode == 2)
            {
              deactivateForm();
            }
          }
          else
          {
            Xrm.Utility.alertDialog(this.statusText);
          }
        }
      };
      req.send();
    }
  }
}

//Function to deactivate the form
function deactivateForm()
{
  var allAttributes = Xrm.Page.data.entity.attributes.get();
  for (var i in allAttributes)
  {
    if (allAttributes[i].getName() != null)
    {
      var attribute = Xrm.Page.data.entity.attributes.get(
      allAttributes[i].getName());
      if (attribute != null)
      {
        var name = attribute.getName();
        if (name != null)
        {
          var control = Xrm.Page.getControl(name);
          if (control != null)
          {
            Xrm.Page.getControl(name).setDisabled(true);
          }
        }
      }
    }
  }
  Xrm.Page.ui.setFormNotification('Information:Form Disabled!', 
  'INFORMATION');
} 

Here is the output of the preceding code:
