add a new empty line in ui-grid

I'm trying to add a new empty line in ui-grid. I've tried looking in different tuto and example, but all that I found didn't reply to my spec, and I wasn't able to adapt it to what I'm looking for.
In fact I'm looking how to add a new empty line in an existing ui-grid neither using a button outside the grid nor a button in the rowfooter.
I'm looking to add a abutton in the grid like the + button shown in the screen shot below
or may be render automatically a new empty line when the rendering the ui-grid and a new one when all rows were filled.
I tried doing that using function in cell template but it's not working.
any help is really appreciated

The first option sounds like more of a CSS issue to me. Essentially, the add button would use some sort of font library containing a +, and you would need to position it in the corner of the grid. Perhaps looking at the grid footer would be a starting place. It sounds like you've seen the basics of creating an add row button here: http://ui-grid.info/docs/#/tutorial/112_swapping_data
The second option (render automatically a new empty line when the rendering the ui-grid and a new one when all rows were filled) requires a JavaScript approach.
The basic logic I followed is:
(Assume) Some data loads from somewhere in a backend (in this sample, it's a simulated load returning a promise as $http or $resource would).
After that data is loaded, we append a new row. We wait for the data first; otherwise we'd not be pushing the new row to the correct location.
Upon completion of the edit action, we set a timeout to ensure subsequent edits on other cells do not keep firing a new row. If the timeout is reached, we append a new row. If a subsequent edit action occurs, and a timeout promise exists (for adding a new row), we cancel it. Once no edit actions occur, and the timeout is reached, we push the new row.
To ensure that we are only taking action when our "extra row" is modified, when we create a row, a reference is maintained to the current row such that we can evaluate whether or not a received event is of interest (var newRowTimeoutPromise).
The core logic in code is below, with a sample implementation in Plnkr:
var extraRow = null,
addNewTimeoutMillis = 2000,
newRowTimeoutPromise = null;
loadData().then(function(data) {
$scope.gridOpts.data = data;
}).finally(function() {
// add initial empty row, and set our reference to it
extraRow = addEmptyRow($scope.gridOpts.data);
})
$scope.gridOpts = {
showGridFooter: true,
onRegisterApi: function(gridApi) {
$scope.gridApi = gridApi;
// listen for cell edit completion
gridApi.edit.on.afterCellEdit($scope, function(rowEntity, colDef, newValue, oldValue) {
// test if the edited row was the "extra row"
// otherwise, and edit to any row would fire a new row
// Set a timeout so we don't create a new row if the user has
// not finished their edit(s) on other fields
newRowTimeoutPromise = $timeout(function() {
if (rowEntity == extraRow) {
// add a new empty row, and set our reference to it
extraRow = addEmptyRow($scope.gridOpts.data);
newRowTimeoutPromise = null;
}
}, addNewTimeoutMillis);
})
// Listen for cell edit start, and cancel if we have a pending new
// row add. Otherwise, each time you finish the edit on a cell,
// this will fire.
gridApi.edit.on.beginCellEdit($scope, function(rowEntity, colDef, newValue, oldValue) {
if (newRowTimeoutPromise != null) {
$timeout.cancel(newRowTimeoutPromise);
}
})
}
};

I used jQuery to fetch and change style of specific cell elements of the cell template.
Here is a helpful Fiddle
Here is the controller script : -
var app = angular.module('app', ['ngTouch', 'ui.grid']);
app.controller('MainCtrl', ['$scope',
function($scope) {
$scope.gridOptions = {};
$scope.Add = function() {
$scope.gridOptions.data.push( { firstName: ' ',lastName:'',company:'' });
$(".ui-grid-coluiGrid").prevObject["0"].activeElement.style.display="none";
$(".ui-grid-cell")[$scope.gridOptions.data.length-2].style.display="inline";
};
$scope.gridOptions.onRegisterApi = registerGridApi;
function registerGridApi(gridApi) {
$scope.gridApi= gridApi
};
$scope.gridOptions.columnDefs = [{
name: 'firstName',
field: 'firstName',
}, {
name: 'lastNamer',
field: 'firstName'
}, {
name: 'ShowScope',
cellTemplate: '<button id="btb" ng-click="grid.appScope.Add()">+</button>'
}];
$scope.gridOptions.data = [{ yourdata}];
}
]);
To make it work properly 2 more things have to be done
Use cellContentEditable to make the rows editable
In order to disable display style of cell template button that appears on cells corresponding to rows of already existing data,you could use angular foreach or a for loop to iterate through these rows and disable style(I tried using renderContainers but it always returns the length of rendered rows outside Add functions as 0).

I have a working plunker over here.
http://plnkr.co/edit/Vnn4K5DcCdiercc22Vry?p=preview
In columnDefs, I have defined a separate column for add:
{
name: 'add',
displayName: '',
enableCellEdit: false,
enableColumnMenu: false,
width: '3%',
cellTemplate: '<div class="ui-grid-cell-contents" ng-click="grid.appScope.addRow()"><span ng-click="grid.appScope.addRow()">Add</span></div>'
}
And
$scope.addRow= function(){
var newlist = {"remarks":'',"testName":''};
$scope.gridOptions.data.push(newlist);
}
Update: A second plunker with bootstrap icons for add/remove

Multiple checkbox columns in jqgrid. Handle onchange event

I am creating a jqgrid with editable fields. I have 2 checkbox columns in jqgrid, one is coming from multiselect: true (to get unique rowId), other column is created inside column model.
I want to handle the onchange(checked/unchecked) event of the checkbox in my column model, independent of other checkbox column(multiselect:true). Any help appreciated. Below is the code snippet.
[{name : "userRole", label: 'OV', width: 40, editable:true, edittype:'checkbox',formatter: 'checkbox', editoptions: {value:"True:False"},
formatoptions: { disabled: false},frozen:true}]
multiselect: true,
onSelectRow: function(rowid){
jQuery(this).editRow(rowid, true);
}

You can use beforeSelectRow callback. The demo demonstrate the approach. It uses the following code
beforeSelectRow: function (rowid, e) {
var $target = $(e.target), $td = $target.closest("td"),
iCol = $.jgrid.getCellIndex($td[0]),
colModel = $(this).jqGrid("getGridParam", "colModel");
if (iCol >= 0 && $target.is(":checkbox")) {
alert("checkbox is " +
($target.is(":checked")? "checked" : "unchecked") +
" in the column \"" + colModel[iCol].name +
"\" in the row with rowid=\"" + rowid + "\"");
}
return true;
}

Define your own formatter function like this in your colmodel,
[{name : "userRole", label: 'OV', width: 40,
editable:true, edittype:'checkbox',formatter: checkboxFormatter,
editoptions: {value:"True:False"},
And your formatted checkbox like,
function checkboxFormatter(cellvalue, options, rowObject) {
return "<input type='checkbox' name='checkboxIsCC'
onchange='your_own_function();'>";
}
Hope this helps you.

I had an issue were not only I had more than 1 check box but also I had to update same column check box values based on the selection of the check box as well as modifying the same row columns.
In regards to the modification of the other checkboxes, when jqgrid modifies the data either by 'setCell' or 'setRowData' operations, it removes the click event. Also there is the problem that for checkboxes none of the edit functions are useful.
I manage to get bits from other people's solution and came to use the delegate jquery functions, that allows the binding of the click to be done each time an object that matches the selector is created. Also in this case only 1 checkbox of only 1 column could be checked at a time.
$(document).delegate("#alarmDownloadListView td[aria-describedby*='stopArm'] input", 'click', function () {
// Function that modifies all the other checkboxes of the same column
deselectOthersStopArmAlarms(this, j);
// Set the Pre and Pos Alarm values to default
var fileIndex = $(this).closest('tr').index();
// Modification of the same row cells
if($(this).is(':checked')){
alarmsGrid.jqGrid('setCell',fileIndex,'preAlarm', defaultPrePosStopArmAlarmValue);
}else{
alarmsGrid.jqGrid('setCell',fileIndex,'preAlarm', null);
}
});
Do not mind the exact operations of the code, what is important is the operations that the binded function does. The CSS selector binds this function to all checkboxes whose name in my colmodel is stopArm.
I hope this answer is useful for some people. I found the delegate to be very useful! :)

multiselect behavior in single select jqGrid

I have a page with a jqGrid in it. Is has to be multiselect:false because I have to allow only one row to be selected, but I also need to select multiple rows (i.e. I want to have many rows marked but only one active).
So I've created a grid whith multiselect:false and a checkbox row with formatter: 'checkbox'
I've also created a master checkbox in the collumn header (the 'name' of the collumn in the colNames is <input id="cbSelectAll" type="checkbox">)
To change all the rows at once when the header is clicked I've created the function:
$('#cbSelectAll').click(function (e) {
var valor = $(this).is(':checked');
$.each($('#grid input[type="checkbox"]'), function (idx, elm) {
var id = $(elm).closest('tr').attr('id');
var cb = $('#' + id + ' td').children().first();
$(cb).attr('checked', valor);
selectedRows[id] = valor;
});
/* other non relevant code */
});
Now that's my problem.
This function works nicelly when I try to unselect the checkbox's but when i try to select then it only works in the first time. On the subsequent clicks the checked attribute is changed but the box is not visually changed.

Instead of attr, try using prop

Adding a custom button in row in jqGrid?

I want to make a simple table that contains a custom button in a row. When the button is pushed, I want to pop up an 'alert' box. I have read some posts on this, for example:
this post
and
this other post, and I don't understand why my code is not working. The buttons are drawn, but pushing them has no effect.
I have three attempts described here.
Version 1. The button click never fires:
$(document).ready(function(){
jQuery("#simpletable").jqGrid({
datatype: "local",
colNames:['A','B','Status'],
colModel:[
{name:'A',index:'A'},
{name:'B',index:'B'},
{name:'status',index:status}
],
data:[
{'A':2,'B':100,'status':"<button onclick=\"jQuery('#simpletable').saveRow('1', function(){alert('you are in')});\" >in</button>"},
{'A':1,'B':200,'status':"<button onclick=\"jQuery('#simpletable').saveRow('2', function(){alert('you are in')});\" >in</button>"},
],
caption: "Demo of Custom Clickable Button in Row",
viewrecords:true,
editurl:'clientArray',
});
});
Html Code:
<table id="simpletable"></table>
EDIT 8/2/12 -- I've learned some things since my original post and here I describe two more attempts.
Version 2: I use onCellSelect. This works, but it would not allow me to put more than one button in a cell. Additionally, I made the code nicer by using the format option suggested by one of the comments to this post.
function status_button_maker_v2(cellvalue, options, rowObject){
return "<button class=\"ver2_statusbutton\">"+cellvalue+"</button>"
};
jQuery("#simpletablev2").jqGrid({
datatype: "local",
colNames:['A','B','Status'],
colModel:[
{name:'A',index:'A'},
{name:'B',index:'B'},
{name:'status',index:status,editable:true,formatter:status_button_maker_v2}
],
data:[
{'A':2,'B':100,'status':"In"},
{'A':1,'B':200,'status':"Out"}
],
onCellSelect:function(rowid,icol,cellcontent,e){
if (icol==2){
alert('My value in column A is: '+$("#simpletablev2").getRowData(rowid)['A']);
}else{
return true;
}
},
caption: "Demo of Custom Clickable Button in Row, ver 2",
viewrecords:true,
}); //end simpletablev2
Markup:
<style>.ver2_statusbutton { color:blue;} </style>
<h3>simple table, ver 2:</h3>
<table id="simpletablev2"></table>
Version 3: I tried to use the solution to w4ik's post, using ".on" instead of deprecated ".live". This causes the button click to fire, but I don't know how to retrieve the rowid. w4ik also struggled with this, and he posted that he worked it out, but not how he did it. I can get the last row selected, but this will always refer to the previous row selected because the button is taking priority.
I would prefer this solution if I could get it to work.
jQuery("#simpletablev3").jqGrid({
datatype: "local",
colNames:['A','B','Status'],
colModel:[
{name:'A',index:'A'},
{name:'B',index:'B'},
{name:'status',index:status,editable:true,formatter:status_button_maker_v3}
],
data:[
{'A':2,'B':100,'status':"In"},
{'A':1,'B':200,'status':"Out"}
],
caption: "Demo of Custom Clickable Button in Row, ver 3",
viewrecords:true,
onSelectRow: function(){},
gridComplete: function(){}
}); //end simpletablev3
$(".ver3_statusbutton").on(
{
click: function(){
//how to get the row id? the following does not work
//var rowid = $("#simpletablev3").attr('rowid');
//
//it also does not work to get the selected row
// this is always one click behind:
//$("#simpletablev3").trigger("reloadGrid");
rowid = $("#simpletablev3").getGridParam('selrow');
alert("button pushed! rowid = "+rowid);
}
});
Markup:
<style>.ver3_statusbutton { color:red;} </style>
<h3>simple table, ver 3:</h3>
<table id="simpletablev3"></table>
In summary, I'm struggling with the issue of getting my button to be pushed at the right time. In version 1, the row gets selected and the button never gets pushed. Version 2 does not use the "button" at all -- It just handles the cell click. Verion 3 gets the button click before the row select (wrong order).
Any help would be appreciated!

You can use action formatter here with each row and make edit and delete button as false in formatOptions like this:
formatoptions: {editbutton:false,delbutton:false}}
And follow these two demos:
http://www.ok-soft-gmbh.com/jqGrid/Admin3.htm
http://ok-soft-gmbh.com/jqGrid/TestSamle/Admin1.htm
And on click event of these custom buttons show your alert:
EDIT
var getColumnIndexByName = function (grid, columnName) {
var cm = grid.jqGrid('getGridParam', 'colModel'), i, l = cm.length;
for (i = 0; i < l; i++) {
if (cm[i].name === columnName) {
return i; // return the index
}
}
return -1;
},
function () {
var iCol = getColumnIndexByName(grid, 'act');
$(this).find(">tbody>tr.jqgrow>td:nth-child(" + (iCol + 1) + ")")
.each(function() {
$("<div>", {
title: "Custom",
mouseover: function() {
$(this).addClass('ui-state-hover');
},
mouseout: function() {
$(this).removeClass('ui-state-hover');
},
click: function(e) {
alert("'Custom' button is clicked in the rowis="+
$(e.target).closest("tr.jqgrow").attr("id") +" !");
}
}
).css({"margin-right": "5px", float: "left", cursor: "pointer"})
.addClass("ui-pg-div ui-inline-custom")
.append('<span class="ui-icon ui-icon-document"></span>')
.prependTo($(this).children("div"));
});
}
If you check this code, I'm trying to find out index value by giving column name as 'act', you can get index on any other column by giving a different column name.
var iCol = getColumnIndexByName(grid, 'Demo'); and the rest of the code will be same for you. //demo is the column name where u want to add custom button
and write your click event for this button.
Let me know if this works for you or not.

How to get column name in dojo grid.

I want to retrieve a particular column name and perform an event on that . how to do that . ? using dojox.grid.datagrid. Like currently i have 3 columns or fields in my grid(ID, names,Email). I want that for a particular column Email. When i click any value under that column the dialog box should not open. But when i click on any where else(on other 2 columns on a particular row) it opens up.

You can connect grid's onCellClick event and get row/col info from the argument. For example:
dojo.connect(grid, "onCellClick", function (e) {
var colField = e.cell.field; // field name
var rowIndex = e.rowIndex; // row index
....
});
And add your logic in the event handler based on those informations.

if you want the dialog to open upon clicking a value in that column (and not the entire cell, which includes whitespace in the cell), then you can use the format function for that field and return a HTML that is an anchor element or any other HTML that is clickable.
for example:
in the grid structure:
columns: [{
label: "Email",
attr: "emailid",
formatter: formatEmail
},
...
function formatEmail(data, item, store) {
return "<a href='mailto:" + data + "'>" + item.nameOfPerson + "</a>";
}
