hide and display div in nested gridview

Posted on 2009-03-30

I've used a javascript item from another posted question, but am finding it difficult to adapt it for a page with multiple mastergrids each containing nested gridviews. Hope that makes sense.

I have 7 mastergrids, each with a unique names. The problem I have is that the doc_id could appear in any number of mastergrids.  When clicking on the link to show the div it makes visible the first on it finds, even if it is not in the mastergrid you are currently viewing. I need it to open the div in the mastergrid/nested gridview that I m clicking.

Hope someone can point me in the right direction. I'm too tired now for looking ;-)
The JavaScript
<script type="text/javascript">
function ShowChildGrid(obj)
    var div = document.getElementById(obj);
    var img = document.getElementById('img' + obj);
    var theFlag = == "none"; = (theFlag) ? "inline" : "none";
    img.src = (theFlag) ? "images/buttons/tl_arrow_down.gif" : "images/buttons/tl_arrow_straight.gif";
The button call
<a href="javascript:ShowChildGrid('div<%# Eval("doc_id") %>');">
                    <img id="imgdiv<%# Eval("doc_id") %>" 
                        alt="Click to show/hide documents" 
                        border="0" src="images/buttons/tl_arrow_straight.gif" />
The div
<div id="div<%# Eval("doc_id") %>" style="display:none;position:relative;" >

Oh, it was so obvious. Of course it wasn't going to work.

I just needed to add a unique div id for each mastergrid.

So for this sample I've added MOD to uniquely identify this mastergrid. Just replace this for each mastergrid with something else.
Button call
<a href="javascript:ShowChildGrid('divMOD<%# Eval("doc_id") %>');">
                    <img id="imgdivMOD<%# Eval("doc_id") %>" 
                        alt="Click to show/hide documents" 
                        border="0" src="images/buttons/tl_arrow_straight.gif" />
The div
<div id="divMOD<%# Eval("doc_id") %>" style="display:none;position:relative;" >
