So now that Editable Grids are released for Dynamics 365, there has also been a few new client side scripting methods made available to interact with the editable grid object.

This post will give you an example of a validating input data for an editable grid using client scripting.


Say I want to get the value of an editable grid cell on change and add some validation on it.

I have a field called ‘Contact Code’ and I want to be notified if I enter a value that is less than 4 characters.


We need a way to reference the current field that was entered and validate its value.

getFormContext Method (Introduced in Dynamics 365)

The key is to pass the context object a parameter to the OnChange grid event and then use the getFormContext method to return the reference of the grid.

The handy thing about this is that it can return a reference to either a Form or Grid control depending on where it was called.

The following code will validate user input through the editable grid for a Contact Code.


Notice how the new methods getByName and getByIndex are used? You can run your debugger to see what other methods are available for the grid object



Once you have created your code, you can upload your grid control (either on form, subgrid or homepage) by navigating to the Events tab.

Upload your script under Form Libraries like you normally do.



Under Event Handlers, specify your Entity, Field and select ‘OnChange’ for the Event.

Effectively, you are going to call a function for the OnChange event that performs the field validation.

Click on Add to add your Jscript library and enter the name of the Function.


Click on ‘Pass execution context as first parameter’ and hit OK. This will pass the executionContext object to the function.



Publish your changes and you will see it in action !

So there it is, you can do basic string validation for editable grids using the new getFormContext method
