Power Apps Portals - Make subgrid read-only dynamically

Hi community, 

 

I want to make a Subgrid dynamically read-only. I added a subgrid in one of the entity forms and I would like that the subrid gets read-only after the first interaction. More specifially: I want that the user is able to associate data in the subgrid for the first time they see it. After the first time (when subgrid contains data) I want that it gets read-only and not editable from the user. Does someone know a way to achieve this? 

 

I could achieve that for entity form fields with custom JavaScript but I don't know how to do that for the subgrids. 

 

Thanks in advance for the help! 

 

Cheers, 

Selim

I am assuming that by "read-only" you mean removing the create button is that it?

 

you can add the following JS to your main entity form or web-page, this should to the trick:

$(document).ready(function(){

    // hide create button once sub-grid contains a record
    $(".entity-grid").on("loaded", function () {
        var tBody = $(this).find("tbody")
        if(tBody.length > 0)
        {        
            $(".grid-actions").hide();
        }
    });
});

Hi Oliver, 

 

Thanks for your reply. 

Your solution does work to hide the subgrid action buttons but the condition doesn't seem to have an impact. The <tbody> element is not empty, even when the subgrid doesn't contain any data. (See the attached SS). So the button is not visible also when the table is empty. 

 

 

did you try the code and didn't work?

I think you inspected the entire page and got the first <table> element.. that refers to your entity form 

as you can see that <table> you are referring to has no <thead> as well

 

what is it shown when you try this in the browser console?: $(".entity-grid").length

if you have online one sub-grid it should appear 1

 

you can always change the condition to find something that suits you, play in the console to get the exact condition you need

I changed the condition as follows and it solved my problem: 

 

 

var tbody = document.querySelector("#Abteilungen > div > div.view-grid > table > tbody");
if (tbody !== null){
  $(".grid-actions").hide();
}

 

 

Your Answer helped me a lot and I will mark it anyway as the Solution. 😉

Thanks and Greetings,
