jqGrid Inline edit: Append custom element next to dropdown

I have the following grid which contains data from a local array (which I save with my own custom call):
var datagrid = [
{name:"Id",description:"description",entityid:"12",amount:"100"},
{name:"Id2",description:"description",entityid:"17",amount:"200"}
];
$grid = $("#grid1").jqGrid({
datatype: "local",
data: datagrid,
height: "auto",
autowidth: true,
shrinkToFit: false,
colNames:['Name','Description', 'Entity', 'Amount', ''],
colModel:[
{index: 'name', name: 'name', editable: true, edittype: 'text'},
{index: 'description', name: 'description', editable: true, edittype: 'text'},
{index: 'entityid', name: 'entityid', editable: true, edittype: 'select', formatter: 'select', edittype: 'select', editoptions:
{
dataUrl: 'url/to/drop/down/data',
buildSelect: function(data)
{
return buildSelectFromJson(data, 'oid', 'oname');
}
}
},
{index: 'amount', name: 'amount', editable: true, edittype: 'text'},
{name:'act', index:'act', sortable:false, width: "140px"}
],
onSelectRow: function(rowid){
rowSelected('grid1', rowid);
},
rowNum: 500,
editurl: "clientArray",
caption: "Details",
ajaxSelectOptions: {contentType: "application/json", dataType: 'json'}
});
$grid.jqGrid('hideCol',['act']);
Next to the "entityid" drop down I want to add a button to show a popup to enter a new entity. I want the new entity to be loaded in the drop-down after the popup closes.
Previously I used editoptions: {value: getValueFunction} but I read some advice in stack overflow which advised against it and anyway I could not load the new entity in the drop-down after the popup closed. But I was able to add the button this way:
function rowSelected(gridid, rowid){
var $grid = $("#" + gridid);
var rowData = $grid.jqGrid('getRowData', rowid);
$grid.jqGrid('showCol',["act"]);
var oneditfunction = function(){
var button = '<input id="newFieldRange" type="button" value="+"></input>';
$grid.find("select").parent().append(button);
$("#newEntity").on('click', function () {
newEntity(gridid, rowid);
});
};
$grid.jqGrid('editRow', rowid, {oneditfunc: oneditfunction});
}
Using the same code for rowSelected function and the code I showed above for the grid, the button is not added. The drop-down is filled with data successfully.
I have the following questions:
1) How can I add a custom button to "entity" cell? Is this not advised? The columns and data I show are not the real data for simplicity reasons. Due to some restrictions, it is not possible to add another column next to the drop-down (we use 'act' column for "Save" and "Cancel" buttons). I would like to add the button in the same cell as the drop-down. Unless there are alternative solutions.
2) How can I force the drop-down to reload after I close the "New entity" popup? I couldn't find anything in the jqGrid wiki.
EDIT: I was able to add the button using onsuccessfunc of jQGrid's editRow. But I am forced to use "select" jqgrid selector without specifying an id, because the and elements do not have any ids. I might need to add another dropdown which would cause issues. Am I missing something?
Thanks in advance for any responses.

jquery & ajax _ call data from database

I'm trying to create a dynamic select box which is using jqgrid-plugin.
I want to call data from my database(oracle) and put it in the select box so that the called data would be showed within select box. I'm not an expert at jquery and ajax.
I've tried to edit the 'edittype' and 'edditoptions' which are attributes of jqgrid colModel[] but it wasn't proper situation.
How can i call data from database to use ajax.
Here is my code below related to jgGrid columns.
jQuery(function($) {
jQuery(grid_selector).jqGrid({
url: '/jqGrid/merchantEstablishmentList',
datatype: 'json',
height: 'auto', autowidth: true,
colNames:
[
'Establishment ID',
'Establish Name',
'Corporation ID'
],
colModel:
[
{name:'ESTABLISHMENT_ID',index:'ESTABLISHMENT_ID', editable:true, sortable:false,search: false},
{name:'ESTABLISHMENT_NAME',index:'ESTABLISHMENT_NAME', editable:true, sortable:false,search: false},
{name:'CORPORATE_ID',index:'CORPORATE_ID',editable:true,edittype:"select", editoptions:{value : },editrules:{required:true},sortable:false,search: false},
],

jqgrid rowobject value is undefined

I use the following code for bind the values in jqgrid.
And i create one link button for access the Particular Action Method.
I need to pass the firstcolumn value to the action method.
But ,If i use this Following href='#Url.Action("ViewApplicants", "HR")?JobsID="+rowObject[0]+" '.It show the undefined Value .How to solve this?
<div>
<table id="Jobtable"></table>
<div id="jQGridPager"></div>
<div id="dialog" title="View Job Detail"></div>
</div>
<script type="text/javascript">
$(document).ready(function () {
$("#Jobtable").jqGrid({
url: '/HR/PassJsonJob/',
datatype: "json",
mtype: 'GET',
colNames: ['Job ID', 'Job Title', 'Job Experience', 'Job Location', 'ViewApplicants'],
colModel: [
{ name: 'JobsID', index: 'JobsID', width: 150, align: 'left', editable: true },
{ name: 'JobTitle', index: 'JobTitle', width: 150, align: 'left', editable: true },
{ name: 'JobExperience', index: 'JobExperience', width: 150, align: 'left', editable: true },
{ name: 'JobLocation', index: 'JobLocation', width: 150, align: 'left', editable: true },
{
name: 'ViewApplicants', index: 'ViewApplicants', width: 150, sortable: false,
formatter: function (cellvalue, options, rowObject) {
alert(rowObject)
return "<a href='#Url.Action("ViewApplicants", "HR")?JobsID="+rowObject[0]+"'>View Applicants</a>";
}
}
],
rowNum: 10,
rowList: [10, 20, 30],
viewrecords: true,
loadonce: true,
gridview: true,
pager: "#jQGridPager",
cellEdit: false,
rowNumbers: true,
width: 1000,
caption: 'Applied Jobs',
viewrecords: true
})
$('#Jobtable').jqGrid('navGrid', '#jQGridPager',
{
edit: true,
add: false,
del: false,
view: false,
search: false
});
});
</script>

It's important to know the format of the server response from the URL /HR/PassJsonJob/. The format of rowObject corresponds to the format of items from the server response. So it could be that rowObject.JobsID instead of rowObject[0] would correct way to access JobsID property. Because you use loadonce: true the format of rowObject could be rowObject[0] at the first load. Later, for example, at local paging or sorting of data, the format of rowObject will be object with JobsID property, so rowObject.JobsID will be correct.
So the usage of rowObject.JobsID or rowObject[0] || rowObject.JobsID could fix your problem.
One more option could be to use the property key: true in the definition of JobsID column in colModel. One can use the property only if JobsID contains unique values in every row. In the case jqGrid will use the value from JobsID column as rowid: the value of id attribute assigned to the rows (<tr> elements) of the grid. In the case one could use options.rowId to access the JobsID value.
UPDATED: One more option exists in free jqGrid fork, which I develop since the end of 2014. The 2-d parameter (options) of the custom formatter has the property rowData, which contains the same information like rowObject, but it has always object format. Thus it's safe to use options.rowData.JobsID instead of rowObject[0] || rowObject.JobsID. One don't need to use the 3-d parameter of the the custom formatter at all. Free jqGrid didn't changed the format of the 3-d parameter to have the best upwards compatibility to the previous versions of jqGrid.

Get the key value of the row of whose cusstom button has been clicked

I found myself in need of what i guess should be a trivial requirement. i have a jqGrid in which i have added a custom button in each row. now i am able to associate a client side click event with it but i want to know the key value (Id) in my case of the row whose custom button was clicked, so that i can proceed with this id and do whatever i want to do.
My code for jqGrid is as below
jQuery("#JQGrid").jqGrid({
url: 'http://localhost:55423/JQGrid/JQGridHandler.ashx',
datatype: "json",
colNames: ['', 'Id', 'First Name', 'Created Date', 'Member Price', 'Non Member Price', 'Complete', 'customButton'],
colModel: [
{ name: '', index: '', width: 20, formatter: "checkbox", formatoptions: { disabled: false} },
{ name: 'Id', index: 'Id', width: 20, stype: 'text', sortable: true, key: true },
{ name: 'FirstName', index: 'FirstName', width: 120, stype: 'text', sortable: true },
{ name: 'CreatedDate', index: 'CreatedDate', width: 120, editable: true, sortable: true, hidden: true, editrules: { edithidden: true} },
{ name: 'MemberPrice', index: 'MemberPrice', width: 120, editable: true, sortable: true },
{ name: 'NonMemberPrice', index: 'NonMemberPrice', width: 120, align: "right", editable: true, sortable: true },
{ name: 'Complete', index: 'Complete', width: 60, align: "right", editable: true, sortable: true },
{ name: 'customButton', index: 'customButton', width: 60, align: "right" }
],
rowNum: 10,
loadonce: true,
rowList: [10, 20, 30],
pager: '#jQGridPager',
sortname: 'Id',
viewrecords: true,
sortorder: 'desc',
caption: "List Event Details",
gridComplete: function () {
jQuery(".jqgrow td input", "#JQGrid").click(function () {
//alert(options.rowId);
alert("Capture this event as required");
});
}
});
jQuery('#JQGrid').jqGrid('navGrid', '#jQGridPager',
{
edit: true,
add: true,
del: true,
search: true,
searchtext: "Search",
addtext: "Add",
edittext: "Edit",
deltext:"Delete"
},
{/*EDIT EVENTS AND PROPERTIES GOES HERE*/ },
{/*ADD EVENTS AND PROPERTIES GOES HERE*/},
{/*DELETE EVENTS AND PROPERTIES GOES HERE*/},
{/*SEARCH EVENTS AND PROPERTIES GOES HERE*/}
);
Help or any pointers would be much appreciated.

The main solution of your problem in the following: you need include parameter, for example e, in the callback of click handle. The parameter has Event object type which contain target property. Alternatively you can use this in the most cases. Having e.target you can goes to the closest parent <tr> element. It's id is the value which you need:
jQuery(this).find(".jqgrow td input").click(function (e) {
var rowid = $(e.target).closest("tr").attr("id");
alert(rowid);
});
Additionally you should make some other modifications in your code to fix some bugs. The usage of
name: '', index: ''
is wrong in colModel. You should specify any non-empty unique name. For example name: 'mycheck'.
Next I recommend you to remove all index properties from colModel. If you use loadonce: true you have to use index properties with the same values as the corresponding name values. If you don't specify any index properties you will have smaller and better readable code. The corresponding values of index properties will be copied by jqGrid internally from the corresponding name values. In the same way you can remove properties like stype: 'text', sortable: true which values are default values (see Default column of the documentation)
The next problem is that you include probably HTML data in the JSON response from the server. (One can't see any formatter for customButton for example). It's not good. In the way you can have problems if the texts of the grid contains special HTML symbols. I find better to use pure data in JSON response from the server. One can use formatters, custom formatters etc on the client side. In the case one can use autoencode: true option of jqGrid which make HTML encoding of all texts displayed in the grid. In the way you will have more safe code which will don't allow any injection (for example no including of JavaScript code during editing of data).
Next remark: I don't recommend you to use gridComplete. The usage of loadComplete is better. See my old answer about the subject.
The last important remark. To handle click events on the buttons placed inside of grid one don't need to bind separate click handle to every button. Instead of that one can use one beforeSelectRow or onCellSelect callback. The answer and this one describe this. The answers use <a> in custom formatter, but <input> works exactly in the same way.

Another approach that can be used to retrieve the id of the row for which the custom button is clicked is by adding formatter to your custom button cloumn
{ name: 'customButton', index: 'customButton', width: 60, align: "right",
formatter: function ( cellvalue, options, rowObject ) {
return "<input type='button' class='custom-button' id='custom"+ rowObject.id +"'/>";
}
}
Now every button has the row id
$('input[id^="custom"]').click(function() {
var id = this.attr('id').replace("custom", ""); // required row ID
});

How to remotely sort an Ext grid column that renders a nested object?

Simple question here, and I'm really surprised I cannot find an answer to it anywhere.
I have the following product model:
Ext.define('Product', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'int'},
{name: 'name', type: 'string'},
{name: 'manufacturer', type: 'auto'}, // i.e. nested object literal
],
});
As can be seen, a product has a nested object inside it that contains details about a manufacturer (id, name, description, etc.).
I display products in an Ext.grid.Panel, like so:
Ext.create('Ext.grid.Panel', {
title: 'Products',
...
remoteSort: true,
columns: [
{text: 'Id', dataIndex: 'id', sortable: true},
{text: 'Name', dataIndex: 'name', sortable: true},
{text: 'Manufacturer', dataIndex: 'manufacturer', sortable: true, renderer: function(manufacturer) {
return manufacturer.name; // render manufacturer name
}
},
],
});
As you can see, all three columns are configured to be sortable, and I am using remote sorting. This works for the first two columns, but the third column (manufacturer) is giving me trouble.
For instance, when a user sorts the grid by product name, Ext sends the following JSON to the server:
{ sort: [{ property: 'name', direction: 'ASC' }] }
This is fine, because the server knows to simply sort by each product's name property.
But when a user sorts the grid by manufacturer, the JSON sent is:
{ sort: [{ property: 'manufacturer', direction: 'ASC' }] }
Since the manufacturer is an object, this does not give the server any idea which property of the manufacturer it should sort by! Is it the manufacturer's id? Or is it the manufacturer's name? Or something else?
For my grid, since I render the manufacturer's name, I'd like to sort it by name. But I see no way to tell the server this. And I certainly don't want to make my server just sort by the manufacturer's name all the time.
If the JSON was sent like this it would be ideal:
{ sort: [{ property: 'manufacturer.name', direction: 'ASC' }] }
Sadly, Ext does not seem to do that (?). So, what's the solution?

Okay, I asked on the Sencha Forums and got a response. It appears you can override getSortParam() in the column config. Example:
columns: [
...
{
header: 'Manufacturer',
dataIndex: 'manufacturer',
sortable: true,
renderer: function(manufacturer) {
return manufacturer.name; // render manufacturer name
},
getSortParam: function() {
return 'manufacturer.name';
},
}
...
]
This will send the ideal JSON I described in my OP. Now I just need to make my server parse this properly! :)
