Show/Hide linked content based checkbox value

[The Mage]

Not sure it matters for this question, but I am currently using the pre-release. (June 9, 2012.)

This seems like it should be simple enough, but it is driving me crazy.

I have a grid using the single record template, so only the detail view shows, and I have linked content under the detail view.

I have a container to conditionally show some options. I placed Net = true in the show/hide expression for the field properties for the container. Works perfectly.

But I want the linked content to act the same way. The linked content section does have a show/hide expression option, and I tried to use it. First with the same Net = true expression. I also tried with quotes. With 1 instead of true. I used the object id - '{grid.componentName}.D.V.R1.NET' both with and without quotes. I tried everything with == also.

I tried to produce a JavaScript function, and without any conditions, I can show and hide the linked content based on a div, but adding in the if/else statement, I cannot seem to be able to figure out how to get the value of the field. The way I was most expecting it to work was - if('{grid.componentName}.D.V.R1.NET' == true) { ... though I would have also thought that - if('NET' == true) { ... would have worked.

I expect there is something I am missing here, but I am still too new to JavaScript, and it's use in Alpha.

Sometimes I just can't find this stuff... where is the show/hide expression for Linked Grids/Content section?

When you "Define Linked Content", under the "Security" button is the "Show/Hide Expression" button.

Re: Show/Hide linked content based checkbox value

We must be in different places 'cause I don't have a Show/Hide Expression button under the Security button (which I do have). I'm in...

Grid Properties, Linked Grids/Content, Linked Content Definition, Linked Content Builder dialog, Define Linked Content button, and across the bottom of this dialog I have three buttons... Override Component Settings, Customize Working message, and Security. Same pre-release as you. How come you're so lucky and get extra buttons???

Not sure what to say, but here it is, with the expression open, and one of my attempts in it.

Build 2721 3940

One thing I didn't even think of is if this is even functional right now.

This was my latest attempt in my JavaScript functions, using an alert box for now to test the if function:

function hide2() {
	if('{grid.componentName}.D.V.R1.NET' == true) {
		alert("Test");
	}	
}

Too funny... just not in my installation... on two different systems.

Re: Show/Hide linked content based checkbox value

Actually do you have the subscriber benefits? I just looked it up, and one of the benefits is a show/hide for the row expander, but I believe this ended up putting it under any linked content, not just the row expander.

Although it does mention run time, so I assume it may not be as dynamic as the show hide in the grid.

Re: Show/Hide linked content based checkbox value

Yeah... I started getting the idea it was something like that... yes I have Subscriber Benefits but forgot to load the SN when I re-installed. Anyway... it's in now and I do have the button and.. as you've found... it doesn't work here... or we've no clue how to enter the expression. You're other idea does work, however.

With your Div around the Linked Content you can use your if statement but it needs fixing a bit. As you said, you're trying to get the value... so that's the clue. I put this into the Client-side event afterDetailViewOpen. This show/hide if statement needs to go into an event that fires when the record changes. There may be other events that work too.

if ($('{Grid.ComponentName}.D.V.R1.PRODNAME').value == '3')
	{
	$('PRODORDERSLINK').style.display = 'none';
	}
else	
	{
	$('PRODORDERSLINK').style.display = 'block';
	}

Yours will work as .value == true

Re: Show/Hide linked content based checkbox value

Nope, still doesn't work. I always get the else.

I altered it as such:

if ($('{Grid.ComponentName}.D.V.R1.NET').value == true)
	{
	$('CustComish').style.display = 'none';
	alert("none");
	}
else	
	{
	$('CustComish').style.display = 'block';
	alert("block");
	}

While the display should tell me which is firing, I still added in the alert.

I did place it in the afterDetailViewOpen. And for some reason it never knows the value is true. I even tried 1, '1', 0, & '0'.

Here are some resources on "dynamic linked content groups" from my library:

Re: Show/Hide linked content based checkbox value

Yes, found what I want, thank you Mr Wood.

Using your blog post/YouTube video, I put the following code into both the onDetailViewRender, and the fields (NET) onClick event.

var cat = {grid.Object}.getValue('D','NET');

switch (cat) {

	case true:
		document.getElementById('childa').style.display = "block";
		break;

	case false:
		document.getElementById('childa').style.display = "none";
		break;

	default:
		document.getElementById('childa').style.display = "none";
		break;
}

I know I didn't need to, but I changed my DIV ID to childa.

Although the {grid.Object}.getValue('D','NET'); is what was probably tripping me up, but this code is much more powerful, and I will be using it elsewhere.

Re: Show/Hide linked content based checkbox value

Run the grid under Firefox and Firebug and see what's going on with that control... what the value actually is.

Re: Show/Hide linked content based checkbox value

Ah. It is a little different:

td id="GRID1.D.TD.R1.NET"

Instead of using:
{Grid.ComponentName}.D.V.R1.NET'

Maybe I should have used:
{Grid.ComponentName}.D.TD.R1.NET'
