Hi guys,

For model-driven form, how to make the whole control read only or un-editable by certain condition ?

For example, in one of its field, I have Posted field. When Posted filled with Yes, all the controls in the form will be read only, cannot edit.

Thanks

You can accomplish this with business rules or with javascript.

In business rules, you would set up your condition, then look through all the controls one at a time and set each to read only. This is an easy, no-code solution but any time you add more fields you will need to add them to the rule.

In Javascript, you can retrieve the tabs and sections on the form, then for each section you can retrieve all controls. This makes for a pretty easy way to loop through all controls and set them Disabled one at a time without needing to explicitly name them all. So, while this approach does require code, it would self-scale and handle any fields being added or removed from the table/form without you needing to make updates.

Hello @Axal,

You can write JavaScript to disable all the fields

function disableAllFields(executionContext) { var formContext = executionContext.getFormContext(); if(formContext.getAttribute(FieldLogicalName).getValue()=YES){ formContext.ui.controls.forEach(function (control, i) { if (control && control.getDisabled && !control.getDisabled()) { control.setDisabled(true); } }); }}
Call the above function in OnLoad Operation

Hi @Pooja08

Unfortunately we cannot Lock Subgrid in OOB way, you need to use document.getElementById to do the same.

let me know if you need more information
