I think the problem is in the FORMATTER and ONAFTEREDIT event.

Unlike all the examples about this subject I read and record data in a MySQL DB through php pages.

I've found a post about it: http://www.jeasyui.com/forum/index.php?topic=1050.msg2274;topicseen#msg2274

I keep trying...

I'll continue here from the previous post (you can find it here: http://www.jeasyui.com/forum/index.php?topic=2079.0)marked as solved from the owner.
Summary:
I've a combobox (provincia) chained to another one (comune).
Both comboboxes are populated from data in mysql.
Actually the chained comboboxes work correctly but when I save on db (in the relate table I've 2 colums (provincia and comune), also using the code in the example presented here: http://jsfiddle.net/hrvKP/, and the row is not anymore editable, I see on the "provincia" column the valueField value and not textField string as expected.

Here the code:

Code:

	<script type="text/javascript">
		$(function(){
			$('#dgb').edatagrid({
				url: 'leggi_records_b.php',
				saveUrl: 'salva_records_b.php',
				updateUrl: 'aggiorna_records_b.php',
				destroyUrl: 'cancella_records_b.php',
				columns:[[
					{field:'provincia',
					 title:'PROVINCIA',
					 width:15,
					 align:'center',
					 sortable:'true',
						formatter:function(value,row){
							return row.provincia;
						},
						editor:{
							type:'combobox',
								options:{
									url:'combobox_provincia.php',
									valueField:'idprovincia',
									textField:'siglaprovincia',
									required:true,
									editable:false,
									onChange:function(value){
										var index = $(this).closest('tr.datagrid-row').attr('datagrid-row-index');
										var ed = $('#dgb').edatagrid('getEditor',{index:index,field:'comune'});
										$(ed.target).combobox('reload','combobox_comuninew.php?prov='+value);
										var row = $('#dgb').datagrid('getRows')[index];
										row['tmpname'] = value;
										var data = $(this).combobox('getData');
										for(var i=0; i<data.length; i++){
											var d = data[i];
											if (d['idprovincia'] == value){
												row['tmpname'] = d['siglaprovincia'];
												return;
											}
										}
									}
								}}},
					{field:'comune',
					 title:'COMUNE INTERESSATO',
					 width:40,
					 align:'center',
					 sortable:'true',
						editor:{
							type:'combobox',
							options:{
								valueField:'nomecomune',
								textField:'nomecomune',
								required:true,
								editable:false
							}
						}
					}
				]],
				onAfterEdit:function(index,row){
					$(this).edatagrid('updateRow',{
						index:index,
						row:{provincia:row.tmpname}
					});
				}

Thanks in advance to anyone can help me to find the definitive solution to this code nightmare

Cannot find a solution to my problem, also trying to implement your example.
I've opened another discussion about the same argument here:

http://www.jeasyui.com/forum/index.php?topic=2147.0

Already tried to add

Code:

formatter:function(value,row){
return row.here_the_name_of_textField_of_the_field;
}, 

in both fields (provincia and comune).
For what I've understood from the example linked I've also to write a "function endEditing" that I don't know how to trig and however is totally out of my abilities.

What I don't understand is why the control must have a similar default behavior especially considering the control already record a valueField and a textField. I supposed that valueField was machine useful to interact with DB, textField for human readability.

However at the time I'm stuck on the problem.

You have to use the code in the example of dependent comboboxes you can find here http://www.jeasyui.com/documentation/combobox.php

I'm not an expert so It's preferable you listen other opinions but actually I've problems with the formatter function so I'd remove it in test phase.
I think also you don't need "data:cmbaxcodes," in field "axCode": jquery will fill this combobox with the onSelect function declared.

Perfect!
your code solved the problem!

Same problem here.
I've two chain combobox in edatagrid.
I need to use, for each combobox, different valueField and textField to chain them and relate data in DB (I pass $prov=valueField variable in php to populate second combobox).
When I edit a combobox it's all ok, but when I deselect the row I see the valueField in cell, not the textField.
Here is the code:

Code:

columns:[[
					{field:'provincia',title:'Provincia',width:400,
						editor:{
							type:'combobox',
								options:{
									url:'combobox_provincia.php',
									valueField:'idprovincia',
									textField:'siglaprovincia',
									onChange:function(value){
										var index = $(this).closest('tr.datagrid-row').attr('datagrid-row-index');
										var ed = $('#tt').edatagrid('getEditor',{index:index,field:'comune'});
										$(ed.target).combobox('reload','combobox_comuninew.php?prov='+value);
										alert(value);
									}
								}
						}
					},
					{field:'comune',title:'Comune',width:400,
						editor:{
							type:'combobox',
							options:{
								valueField:'idcomune',
								textField:'nomecomune'
							}
						}
					}
				]]

I suppose I have to use formatter function for both columns but I don't understand how to implement the function with my code that uses edatagrid.

Hi all,
I'm a newbie so sorry in advance for the probably silly question:

I've tried to use the code explained in the topic http://www.jeasyui.com/forum/index.php?topic=559.0 about the chained combobox (city/country) but I don't understand what is and how to use the parameter "idx" in:

Code:

onChange:function(value){
						// get the country editor
						var ed = $('#dg').datagrid('getEditor',{index:idx,field:'country'});
						// reload its data
						$(ed.target).combobox('reload','get_data.php?city='+value);

And how to pass in get_data.php the "value".

Thanks in advance.
