Enable/Disable Save Button on Master page based on Child page record

Unfortunately we do not have such sample code available.
Most likely you need to add this code to Details table Add/Edit page JavaScript OnLoad event.

Here is the code to enable/disable button:

Thanks Admin for reply. But it did not work for me. Because "SAVE" button is on Master Add/Edit Form in my case not on Detail Add/Edit Page. Detail Add/Edit form is in "Tab" folder on my Master Add/Edit page, so there is only one "SAVE" button on Master form only. Another thing how can I put the condition for enable/disable in the code you provided. Thanks again.

I can confirm that code added to Details table Add/Edit page Javascript OnLoad event is able to disable/enable Save button of the Master table.

Thanks Admin for so quick reply. I used Detail Form as "Inline Add/Edit" only to accommodate into "Tab" folder on Master page. I didn't create any separate Add/Edit page for detail table. How and where then I should put those code on detail table page? Thanks again.

I checked with your advice and its work now. I see "SAVE" button can be disabled. I put that code to Details table Add/Edit page Javascript OnLoad event. But I like to enable this button when user complete the required fields on detail page. How can I can make this happen conditionally? Could you please give me with some example code? Thanks a lot.

You need to add your code to 'onchange' event of those required fields.
Take a look at this example:

Your code will be fired every time the content of one of fields is changing and this is where you can conditionally enable or disable Save button.

Dear Admin, Thank you so much. I used this code with no luck. Could you please help me out again? I am not pro php but learner. Thanks.
var ctrlsaveButton = Runner.getControl (pageid, 'saveButton');

var ctrlProviders = Runner.getControl(pageid, 'detailid');
ctrlProviders.on('change', function(e){
if (this.getValue() == '$('input[type=select]'){
ctrlsaveButton.enable();

}else{

ctrlsaveButton.disable();

}

});

Unfortunately we do not have sample code tailored for this specific task. You either need to learn a bit of Javascript or to hire someone to do this for you.
