DYNAMICS 365 HOW TO USE FORM CONTEXT IN HTML WEB RESOURCE

Everyone knows that Xrm.Page is deprecated and it is replaced by the executionContext.getFormContext() method, where the execution context is passed from the form as the first parameter to the function you are calling (reference link).

In the same above link, it is mentioned that Although Xrm.Page is deprecated, parent.Xrm.Page will continue to work in case of HTML web resources embedded in forms as this is the only way to access the form context from the HTML web resource .

However, you can access the form context from HTML web resource without using Parent.Xrm.Page and this is the topic for today.


You have to create a function that will return the formContext, then, on load of the form call this function, and finally call this function from the web resource.
  1. Declaration of a variable and function that return the formContext

    var formContext;
    function getFromContext() {
    return formContext;
    }

  2. On load of the form, fill the variable by calling the function that returns the formContext

    function onLoad(context) {
    //Set Form Context
    formContext = context.getFormContext();
    Xrm.formContext = getFromContext();
    }

  3. Call the function that returns the formContext from the web resource in the form without using parent.Xrm.Page
    var recordId = parent.Xrm.formContext.data.entity.getId();

Bonus Tip:
In case the web resource opens another web resource in a new window, you can still access the formContext as well from the new window using the following syntax:
var recordId = window.top.opener.parent.Xrm.formContext.data.entity.getId();


Hope This Helps!

    Hi there - It looks like I could use this to call an external web resource including the account name (or another field). Would you be able to explain how I would put this into practice using your code above please?

      Hello Mick,
      To call a webresource, you should add it as a web resource file into D365 and call it as follows
      var customParams = "Param1=" + YourFieldValue ;
      Xrm.Navigation.openWebResource("WebResourceName", null, encodeURIComponent(customParams));

DISABLE ALL FORM FIELDS IN DYNAMICS 365 USING JAVASCRIPT

Image
To make the form read-only in Dynamics 365 you have 3 options: changing record status to Inactive, Business rule, JavaScript. The purpose of this article is to know how to make all form fields disabled with JavaScript. Changing record status to Inactive might not very suitable for some cases where cascading rules might be applied to children records. On the other hand, even though it is a low code solution, using business rule to make all fields read-only will be very time consuming especially if a field is removed from the form or a new field is added to the form. However, using JavaScript will allow you to set all form fields to read-only dynamically with a small piece of code and you can do it based on a certain condition of an attribute value. Make read-only the whole fields of a form based on a certain condition

DYNAMICS 365 HOW TO REFRESH SUBGRID IN JAVASCRIPT

In other posts, we saw how to change the selected view of a subgrid and how to filter subgrid in JavaScript. In this post, we will see how to refresh a subgrid in JavaScript in order to show the latest records related to a parent record upon an action on the form or clicking a ribbon button. For the sake of this post, I will take the example of the cases subgrid related to an account record. Let's take the scenario, where an action is done on the client side that adds a case related to the account record. Therefore, the sub-grid should be automatically refreshed to reflect the updated list of cases. In order to do this, a JavaScript function should call the refresh() in order to refresh the subgrid and display the expected result. function refreshSubGrid(context) { var formContext = context.getFormContext();
