Dynamics 365 – Javascript – formContext – Lock form & fields after subgrid is loaded

By Ritchey Hazeu

Hi! In some scenario’s you would like to know if there are any related records and based on this condition, lock a form or any fields (or do any other action!).

First you would like to count the related records which are present in a subgrid:

var gridContext = formContext.getControl("Gridname");// get the grid context

var count = formContext.getControl("Gridname").getGrid().getTotalRecordCount();

And you would like to run this code after the Subgrid is loaded. So you will use the gridContext and let it run on load (apart from the form).

gridContext.addOnLoad(GridOnloadFunction);

How does this code look when you would like to lock fields?

function lockFieldsOnCount(executionContext) {

var formContext = executionContext.getFormContext(); // get the form context
var gridContext = formContext.getControl("Gridname");// get the grid context
    
var GridOnloadFunction = function () { 
var count = formContext.getControl("Gridname").getGrid().getTotalRecordCount();

if (count > 0){
                
var lockAccount = formContext.getControl("field1").setDisabled(true);

var lockContact = formContext.getControl("field2").setDisabled(true);

}

else {
                
var lockAccount = formContext.getControl("field1").setDisabled(false);

var lockContact = formContext.getControl("field2").setDisabled(false);
}
	
};
    gridContext.addOnLoad(GridOnloadFunction); //run onload of subgrid
}

function lockFieldsOnCount(executionContext) {

var formContext = executionContext.getFormContext(); // get the form context
var gridContext = formContext.getControl("Gridname");// get the grid context
    
var GridOnloadFunction = function () { 
var count = formContext.getControl("Gridname").getGrid().getTotalRecordCount();

if (count > 0){
                
formContext.data.entity.attributes.forEach(function (attribute, index) {    
var control = Xrm.Page.getControl(attribute.getName());
if (control) {
control.setDisabled(true)
	
}
});
	
else {
formContext.data.entity.attributes.forEach(function (attribute, index) {    
var control = Xrm.Page.getControl(attribute.getName());
if (control) {
control.setDisabled(false)
	
}
});
}
	
};
   gridContext.addOnLoad(GridOnloadFunction); //run onload of subgrid
}
