3.0 beta 2

Disable sort feature

Is there a way to disable the sorting? I have a recordset that is returning about 500 records and it seems to freak out the browser (IE6.0) and if you look in taskmanager the CPU usage pegs out at 100%.

The easiest way is to remove mousedown event handler, which triggers sorting...
obj.getTemplate("top/item").setEvent("onmousedown", null);

Is there a way to reassign the sort from the left mouse button to the right mouse button?? ( I would like to be able to reassign the onclick to a custom function and then use the oncontextmenu to initiate sort)

obj.sort(columnIndex, direction);

This works smooth. Why can't you pop a custom context menu and add the above code? Just an idea, never tested this one...

Check /datagrid.1608/ if you need more than one level of sorting

And you can put your own event handler instead of the default one:

obj.getTemplate("top/item").setEvent("onmousedown", myEventFunction);

Hi Alex.

By using your example ... how can I pass into myEventFunction, the column index? I need to resort the data on the server side so I'd like to capture the event of clicking on a header, then passing it (the column index) into the myEventFunction which will send the request back to the server.

I thing the event handler is generic event handler

Works in IE like this (you need to parse id to get column#)

function headerClicked(e) {
obj.getTemplate("top/item").setEvent("onmousedown", headerClicked);

In case of mozilla use 'e.target.id'

FYI: There might be better ways of doing it. hehe

I have found the following code on the forums which I have working .... all about setting the url to the server. How do I do that?

var iCurrentSortIndex = 0;
var strCurrentSortDir = "";
var iCurrentPage = 1;
var SortFunction = function(src){

var iSortIndex = src.getProperty("item/index");
var strSortDir = src.getProperty("sort/direction");
if (iSortIndex != iCurrentSortIndex) { 
 strSortDir = "ascending"; 
} else if (strCurrentSortDir == "descending") { 
 strSortDir = "ascending"; 
} else { 
 strSortDir = "descending";
this.setProperty("sort/index", iSortIndex);
this.setProperty("sort/direction", strSortDir);
var strURL = "testing.php?blahblahblah";
//this.setURL(strURL); <---- both lines case object doesn't support
//this.request(); <--------- this property or method
iCurrentSortIndex = iSortIndex;
strCurrentSortDir = strSortDir;

obj.setAction("columnSort", SortFunction);

In the above posted code this refers to grid object.

So the code required will be something like this

this.setProperty("sort/index", iSortIndex); 
this.setProperty("sort/direction", strSortDir); 

var table = new Active.Text.Table;
table.setURL(strURL );

iCurrentSortIndex = iSortIndex; 
strCurrentSortDir = strSortDir; 

obj.setAction("columnSort", SortFunction);

Use this function
// disable sort grid
obj.sort = function(index, direction){
return true;

I am glad I can disable the sorting so painlessly. What I could not found so far is how to turn off the underlining of the column header. If you hover over the column header in the xp grid you get a orange underline. It does not make sense if the sorting is turned off.

Is it possible to disable sorting on only one column header cell?
I'm trying to put a "check all" checkbox in the rightmost column header of the grid. The checkbox appears fine but when I try to click it the column resorts instead and the checkbox in the header remains unchecked.
Alternately, is there a way to force the checkbox to receive the focus of a click in a column header ?

I'm using version 1.

try -- disable sorting on col 4
grid1.onHeaderClicked = function(event,index){
if (index==4) return 'disabled';
return "";

to restore initial sort
grid1.sort(""); // hide marker

When attempting to disable the sort i get the following error:

//disable sort
obj.getTemplate("top/item").setEvent("onmousedown", null);

this[get] has no properties

where is "top/item" set???
