jqGrid how to collapse row when clicking on other row - jqgrid

Question

In a main grid, when I click on one row, it become 'highlighted' and the seven subgrids are showed.
Here is an example where first row is selected, and near to be edited (work in progress) :
Now, if I click on second row of the main grid, the first is hidden and the second selected. I click after on edit button and a warning appears : no selected row !
If I click again on the second row, it become unselected, and again I click for selecting and editing, that runs fine ! So I presume that my code for switching between collapsed and expanded status is somewhere wrong :

Following Oleg's answer, I join the full code (limited to 30000) of my program :
jQuery(function ($) {
var resetAltRows = function () {
$(this).children("tbody:first").children('tr.jqgrow').removeClass('myAltRowClass');
$(this).children("tbody:first").children('tr.jqgrow').each(function(){
var arbo=$(this).find('td:eq(0)').text().substr(0,1);
$(this).addClass('myAltRowClass1'+arbo);
if(arbo==1)$(this).find('td:eq(1) input:checkbox').attr('checked','checked');
});
$(this).children("tbody:first").children('tr.jqgrow:visible:odd').addClass('myAltRowClass');
};
var OldSelectedRow=null,
height=$('body').height()-235,
numRows=Math.floor(height/23)-(Math.floor(height/23)%5),
heightRows=numRows*23,
myGrid = $("#tab51");

myGrid.jqGrid('resetSelection');
}
});});
where I don't use any subGridOptions so I think that false is the defaultValue of reloadOnExpand.
I have added in OnSelectedRow function 2 alerts, at beginning and ending of function.
The first click display fine selrows for begin and end, but for next click, the end alert displays 'null'.
I have tried also to delete all parts into 'subGridRowExpanded' and 'subGridRowColapsed' functions.
The trouble doesn't happen, begin and end selrows are fine and I can edit row as I want.
Inner workings of jqGrid seem very complicate for me as I'm not used to work with it, and I have to thank you one more time for all time you spend for helping noobs as me. You are always right in your comments and I hope you will be for long time on this forum.
Thanks again. Have a nice day. JiheL
UPDATED 2013-04-22
After applying all suggests from Oleg, I made some changes in the 20 scripts of my app, which all are built in the same way.
For this subject, here is the small part of onSelectRow I changed :
onSelectRow:function(id){
var expanded = $("td.sgexpanded", myGrid)[0];
if(expanded){
$(expanded).trigger("click").parent().removeClass('ui-state-highlight');
}
myGrid.jqGrid('expandSubGridRow',id);
$('#'+id).addClass('ui-state-highlight');
alert(id+' '+myGrid.jqGrid('getGridParam','selrow'));
},
but no more luck for the result, I can't edit a row which has been expanded after collapse other row. I don't understand why selrow changes after collapse old row and expand selected row.
I hope someone could drive me about this trouble, I think I'm not alone to meet this problem.
Many thanks in advance for your kind help, really appreciated. JiheL

After applying Oleg's suggests the main problem (edit an expanded row after collapsing other) seems to be solved. But setting selected row to top of grid runs fine with five first rows, but not with following rows. Strange ! Here is a snapshot of fact :
Strange because demo in http://jsfiddle.net/jihel/JMcKF/ runs fine and has been created with my app code ! I'm searching what can be wrong or alter scrollTop, if someone has already met such a trouble and have an idea for solving, many thanks for all your help. Have a nice day

Answer 1

It's difficult to analyse so long code. So I post just some comments about the potential problems which I can see in the code after I looked through it.
The main problem which I see: you should use idPrefix option in all subgrids (or in the main grid and subgrid). The value of idPrefix option option should depend on rowid where the subgrid will be opened. For example you can use
idPrefix: "s_" + row_id + "_a_"
for the first subgrid, idPrefix: "s_" + row_id + "_b_" for the second subgrid and so on.
I recommend you don't use . (dot) or any other meta-characters in the column name. It's origin of potential errors in your code and in the code of jqGrid. You should understand that the name property will be used to build id attributes of some internal elements of jqGrid. There are some restrictions in CSS which characters are permitted in id attribute. Additionally jqGrid have to build selectors to get the corresponding elements from the page. For example $("#" + rowid) will be wrong selector if rowid includes . because the selector ("#a.b") will be interpreted as: element with id=a and the class b instead of id="a.b". Old versions of jqGrid don't worked at all with such ids and such names. Recent version of jqGrid should works, but nevertheless usage of meta-characters in ids increase the complexity of the code in many time. Do you really need it?
Because of almost the same problem I don't recommend you to use the same name property for different tables. It could be important if you plan to use searching filter for multiple grids or subgrids (to use filterToolbar for multiple grids). Currently you use 'c.code' for example in multiple subgrids which is potential origin of the future problems.
If you really need to use . for searching and you use datatype: "json" without loadonce: true then you can use index which has . and name which has no .. For example you can use name: 'b_id', index: 'b.id'. If you use index value which is the same as the value of name property, it's recommended to remove index property from the column definition.
Additionally I would don't recommend to use scroll:true option of jqGrid. In general virtual scrolling is nice feature, but in my opinion the implementation of virtual scrolling have many bugs abd side effects. So I recommend don't use it. If you really hardly need the feature then you should use it in the form scroll:1 and you have to invest more time in the debugging.
The last remark: I don't recommend usage of gridComplete. I recommend to use loadComplete instead. See the answer for more details.
The last remark: i recommend to use gridview: true in all grids and subgrids which you use.
UPDATED: I am not sure that I full understand which behavior you want to implement in onSelectRow, but the following implementation
onSelectRow: function (rowid) {
var $self = $(this),
$this = $("#" + $.jgrid.jqID(rowid)), // the row
$expanded = $self.find("td.sgexpanded");
if ($expanded.length > 0) {
$expanded.trigger("click");
}
$self.jqGrid("expandSubGridRow", rowid);
$self.jqGrid("setSelection", rowid, false);
$this.closest(".ui-jqgrid-bdiv").scrollTop($this.position().top);
}
