How to expand all rows in jqxTreeGrid

[yougotnetParticipant]

How can I expand all rows in a TreeGrid?

When I use getRows, it only returns the top level rows.

Hi yougotnet,

getRows returns a hierarchy of rows i.e it returns all rows in hierarchical manner i.e a row may have sub rows, etc. It will not return a flat list. If there’s a sub row, it will be stored in member, called records. At present, there’s no API for expanding/collapsing all rows. We will consider adding such API in future versions.

Here is the code to expand all the rows:

ready: function() // Expanding all rows (parent and its sub-lings)
{
var rows = $(“#treeGrid”).jqxTreeGrid(‘getRows’);
var traverseTree = function(rows)
{
for(var i = 0; i < rows.length; i++)
{
if (rows[i].records)
{
idValue = rows[i][idColumn];
$(“#treeGrid”).jqxTreeGrid(‘expandRow’,idValue);
traverseTree(rows[i].records);
}
}
};
var idColumn = $(“#treeGrid”).jqxTreeGrid(‘source’)._source.id;
traverseTree(rows);
}

if tree with 2 levels you can do this:

var rows = $(“#treeGrid”).jqxTreeGrid(‘getRows’),
for(var i=1;i <= rows.length; i++){
	$(“#treeGrid”).jqxTreeGrid("expandRow",rows[i-1].UNIQUEID);
}

Thank you Peter!

When I use this method , I am getting below error . Not sure what I am missing , I tried by including seperate jqx reference files instead of jqx-all.js. Functions like export is working perfectly fine.

collapseAll as well not working . Any help will be appreciated. I am using version 3.8.2

jqxCore: Invalid parameter ‘[expandAll]’ does not exist.
jqx-all.js, line 7 character 5478

Peter , Ignore my previous post . Actually I was using 3.8.0.
Updated my js files to 3.8.2 and it works like a charm . Thanks again for your quick response !

Hi arunkumar.rc,

expandAll/collapseAll are available since 3.8.2 and not available in previous versions. Information: http://www.jqwidgets.com/jquery-widgets-documentation/documentation/releasehistory/releasehistory.htm

Hi Peter.

Do you know why the expandAll renders the checkboxes of the children nodes with a black square?
For example: http://jsfiddle.net/yw02cpwe/3/

Hi Gerasimos,

We will investigate that.
