[SOLVED] Cascade Combogrid - load data after select of first combogrid

[acreonte82]

Hi to all,
I've a problem or better I don't know how to implement this kind of situation:
I've 3 combogrid and the kind of load data is remote mode.  There are no problems to retrive data and the "live search" function works.
But now I want to load the data after the user selection: the data of second  combogrid is load after the selection of first combogrid .
This is my sample js code for the combogrid

Code:

$(function(){
	$('#assay_type_id').combogrid({
		panelWidth:500,
		url: 'controller/enumerate_assay_type_id.php?man=6',
		idField:'id_assay',
		textField:'description',
		mode:'remote',
		fitColumns:true,
		columns:[[											
			{field:'description',title:'Assay',width:250}										
		]]
	});
	$('#sample_type_id').combogrid({
		panelWidth:500,
		url: 'controller/enumerate_biological_sample_type.php',
		idField:'id_biological_sample_type',
		textField:'description',
		mode:'remote',
		fitColumns:true,
		columns:[[											
			{field:'description',title:'Tessuto',width:250}										
		]]
	});
}

How can I extend the combogrid called "sample_type_id" to retrive data after the input of " assay_type_id"?
How I can do this? I tryed to find in the forum some similar situation but with not a good result.

Thanks for all

Please try to attach the 'onChange' event handler to the '#assay_type_id' combogrid.

Code:

$('#assay_type_id').combogrid({
	panelWidth:500,
	url: 'controller/enumerate_assay_type_id.php?man=6',
	idField:'id_assay',
	textField:'description',
	mode:'remote',
	fitColumns:true,
	columns:[[											
		{field:'description',title:'Assay',width:250}										
	]],
	onChange:function(value){
		var g = $('#sample_type_id').combogrid('grid');
		g.datagrid('load',{assay_type_id:value});
	}
});
