Interaction with gridData on ui-grid edit events - javascript

I am using Angular ui-grid and am pretty new at it. I receive an array of objects to render data for each row. Each object, hence each row , has a field change:false which marks whether any field on that row has been edited or not. I have kept this field visible : false on screen.
However, whenever any change is made to any column of any row, I want to set this field as change:true.
How can this be achieved on the change of a ui-dropdown field or any other field for that matter.
I have this as my changing column:
{ name: "carrier_influence_group", displayName: "Carrier influence group", enableCellEdit: true,
editableCellTemplate: 'ui-grid/dropdownEditor', type:'object', cellFilter: 'cigFilter', editDropdownValueLabel: 'name',
editDropownOptionsArray: [{ id: 10, name: 'Small' }, { id: 11, name: 'Medium' }, { id: 12, name: 'Large' }]
},
I tried looking for any options available. But couldn't find any way in official docs. Kindly suggest a way or some relevant links

You can use the afterCellEdit event for this.
$scope.gridOptions.onRegisterApi = function (gridApi) {
$scope.gridApi = gridApi;
gridApi.edit.on.afterCellEdit($scope, function (rowEntity, colDef, newValue, oldValue) {
if (newValue !== oldValue) {
rowEntity['change'] = true;
}
});
});

IgGrid selectRow Issue

I am trying to implement the "RowSelectors" feature on the iggrid, but it will not change to a the next row.
On further inspection, i have got the selected row method and each row shows the same id. I am returning my data via ajax, if i use static json in a variable and use that as a datasource, it works as expected so not sure what the issue is..
$("#selector").igGrid("selectedRow");
I can only acheive a row change when holding control and clicking..
Object {element: n.fn.init(1), index: 0, id: 3407751001}
then next row is
Object {element: n.fn.init(1), index: 1, id: 3407751001}
Settings..
features: [
{
name: "Sorting",
columnSettings: [
{
columnIndex: 4,
allowSorting: true,
firstSortDirection: "ascending",
currentSortDirection: "descending"
}
]
},
{
name: 'RowSelectors',
enableCheckBoxes: true,
checkBoxStateChanging: function (ui, args) {
return false;
},
multipleSelection: true,
rowSelectorClicked: function (evt, ui) {
// Handle event
},
},
{
name: 'Selection'
}
]
The issue is already resolved, but I'm adding the answer so it doesn't stay unanswered.
The primaryKey column the igGrid uses needs to be a column with unique identifiers for each record.

Why am I not getting any values displayed in my ui-grid dropdown?

I have this following code for ui-grid column Definition:
{ name: "carrier_influence_group", displayName: "Carrier influence group", enableCellEdit: true, showSortMenu: false,
editableCellTemplate: 'ui-grid/dropdownEditor', editDropDownOptionsArray: [ { id: 11, value: 'Medium' }, { id: 12, value: 'Large' }],
editDropdownIdLabel: 'id',editDropdownValueLabel: 'name'}
I am binding the name of these object to the column.
Every thing is fine normally. The grid as such renders correctly. But when I dbl click to edit this row, the text in this row disappears. A dropdown appears but it has no option to select from.
I tried changing my array to:
[ { id: 11, name: 'Medium' }, { id: 12, name: 'Large' }]
What is missing here. I have seen this official code. Seems like all is similar except for a filter. I do not need any such filter. Is it necessary to have one. The official docs do not mention anything about it.
Already referred http://stackoverflow.com/questions/28323540/showing-readable-data-in-ui-grid-with-editable-drop-down-cell
First thing to try - it should be editDropdownOptionsArray not editDropDownOptionsArray (note the case).

Kendo UI Grid: if I make changes and save them, I can still cancel them afterwards. How to lock them in?

I have a Kendo UI Grid bound to a local data source. If I make some changes and click on "Save changes", and then I click on "Cancel changes", the changes are rolled back. I expected them to be "locked in" because I saved them.
Furthermore, if I make a change, save it, make another change, save again and finally cancel, both changes are rolled back.
See UPDATED fiddle, with problem and solution:
http://jsfiddle.net/q24ennne/7/
My HTML:
<div id="grid"></div>
My JavaScript:
window.gridData = [
{ id: 1, text: "Uno" },
{ id: 2, text: "Dos" },
{ id: 3, text: "Tres" },
{ id: 14, text: "Catorce" },
];
(function() {
$('#grid').kendoGrid({
toolbar: ["save", "cancel"],
editable: true,
saveChanges: function(e) {
gridData = $('#grid').getKendoGrid().dataSource.data();
$('#grid').getKendoGrid().refresh();
console.log("gridData:");
console.log(gridData);
},
columns: [{
field: "text",
title: "No."
}],
dataSource: {
data: gridData,
}
});
})();
Thanks!
You need to include a schema for your datasource that specifies which property is the id of each item. In your case this happens to also be called "id" so add this:
dataSource: {
data: gridData,
schema: {
model: { id: "id" }
}
}
The grid will then correctly track and keep your saved changes.

Edit a cell and keep the editing status when losing focus in ui-grid 3.0

My starting point is this Plunker, that contains a table made with AngularJS and UI-Grid 3.0. When I double-click on a cell with a template (let's take as an example the gender one), a select element is visible as it enters in edit mode.
But when this cell loses the focus (i.e. clicking outside the table or on another cell), the select element disapears and the cell goes back to the previous state.
Even though that is the default thing to do and the usual one, I'd like to keep the edit mode of each cell no matter if the focus is lost, and go back to the fixed mode only when an option is selected. I need to be able to keep one or more cells in this edit mode at the same time.
Also It'd be great if the gender field in the JSON array could be in a "intermediate" state while in edit mode (it could be the current third item "both" or anything else) and change to "male" or "female" once an option is selected.
The current code is the following:
HTML:
<div ng-controller="MainCtrl">
<div ui-grid="gridOptions" ui-grid-edit class="grid"></div>
<hr>{{gridOptions.data | json}}
</div>
JS:
var app = angular.module('app', ['ngAnimate', 'ui.grid', 'ui.grid.edit']);
app.controller('MainCtrl', ['$scope', '$http',
function($scope, $http) {
$scope.genderTypes = [{
ID: 1,
type: 'female'
}, {
ID: 2,
type: 'male'
}, {
ID: 3,
type: 'both'
}];
$scope.gridOptions = {
enableSorting: true,
enableFiltering: true,
enableCellEditOnFocus: true,
columnDefs: [{
field: 'name',
sort: {
direction: 'desc',
priority: 1
}
}, {
field: 'gender',
editType: 'dropdown',
enableCellEdit: true,
editableCellTemplate: 'ui-grid/dropdownEditor',
editDropdownOptionsArray: $scope.genderTypes,
editDropdownIdLabel: 'type',
editDropdownValueLabel: 'type'
}, {
field: 'company',
enableSorting: false
}]
};
$http.get('https://rawgit.com/angular-ui/ui-grid.info/gh-pages/data/100.json')
.success(function(data) {
$scope.gridOptions.data = data;
});
}
]);
I have just looked lightly at your code but you should have editDropdownIdLabel as 'ID'. This should do it. if you have a more complex change going on maybe look at my suggestion below.
There is a function in ui-grid called uiGridEventEndCellEdit, even though you have changed the data in the grid have you pushed the changes to your server side? So after you changes something you can lose focus and catch the event and then update your model accordingly.

Render dynamic components in ExtJS 4 GridPanel Column with Ext.create

I've got an ExtJS (4.0.7) GridPanel that I'm populating from a store. The values that I display in the GridPanel's column need to have a different view depending on the type of data that's in the record.
The ultimate goal is that records with "double" or "integer" value for the record's type property present a slider to the user that they can adjust, and a type of "string" just renders some read-only text.
I've created a custom Column to do this. It inspects the type in the renderer and determines what to render.
I've got the "string" working fine with the code below, but struggling with how I can dynamically create and render the more complicated slider control in the column.
This simplified example is just trying to render a Panel with a date control in it as if I can get that going, I can figure out the rest of the slider stuff.
Ext.define('MyApp.view.MyColumn', {
extend: 'Ext.grid.column.Column',
alias: ['widget.mycolumn'],
stringTemplate: new Ext.XTemplate('code to render {name} for string items'),
constructor: function(cfg){
var me = this;
me.callParent(arguments);
me.renderer = function(value, p, record) {
var data = Ext.apply({}, record.data, record.getAssociatedData());
if (data.type == "string") {
return me.renderStringFilter(data);
} else if (data.type == "double" || data.type == "integer") {
return me.renderNumericFilter(data);
} else {
log("Unknown data.type", data);
};
},
renderStringFilter: function(data) {
// this works great and does what I want
return this.stringTemplate.apply(data);
},
renderNumericFilter: function(data) {
// ***** How do I get a component I "create" to render
// ***** in it's appropriate position in the gridpanel?
// what I really want here is a slider with full behavior
// this is a placeholder for just trying to "create" something to render
var filterPanel = Ext.create('Ext.panel.Panel', {
title: 'Filters',
items: [{
xtype: 'datefield',
fieldLabel: 'date'
}],
renderTo: Ext.getBody() // this doesn't work
});
return filterPanel.html; // this doesn't work
}
});
My problem really is, how can I Ext.create a component, and have it render into a column in the gridpanel?
There are a few ways that I have seen this accomplished. Since the grid column is not an Ext container it can not have Ext components as children as part of any configuration the way other container components can. Post grid-rendering logic is required to add Ext components to cells.
This solution modifies your custom column render so that it puts a special css class on the rendered TD tag. After the grid view is ready, the records are traversed and the custom class is found for appropriate special columns. A slider is rendered to each column found.
The code below is a modified version of the ext js array grid example provided in the Sencha examples. The modification mixes in the custom column renderer and the post grid rendering of sliders to TD elements.
This example only includes enough modification of the Sencha example to show the implementation ideas. It lacks separated view and controller logic.

I did something like this when I needed to render a small chart (essentially a spark chart) in a grid column. This solution is similar to sha's, but it's more robust and delegates the rendering to the component being rendered rather than the Column, which doesn't really have a render chain.
First, the column class:
Ext.define("MyApp.view.Column", {
extend: "Ext.grid.column.Column",
// ...
renderer: function (value, p, record) {
var container_id = Ext.id(),
container = '<div id="' + container_id + '"></div>';
Ext.create("MyApp.view.Chart", {
type: "column",
// ...
delayedRenderTo: container_id
});
return container;
}
});
Note the delayedRenderTo config option. Just like renderTo, this will be the DOM ID of the element that the chart component will render to, except that it doesn't need to be present in the DOM at the time of creation.
Then the component class:
Ext.define("MyApp.view.Chart", {
extend: "Ext.chart.Chart",
// ...
initComponent: function () {
if (this.delayedRenderTo) {
this.delayRender();
}
this.callParent();
},
delayRender: function () {
Ext.TaskManager.start({
scope: this,
interval: 100,
run: function () {
var container = Ext.fly(this.delayedRenderTo);
if (container) {
this.render(container);
return false;
} else {
return true;
}
}
});
}
});
So during initComponent(), we check for delayed render and prepare that if necessary. Otherwise, it renders as normal.
The delayRender() function itself schedules a task to check every so often (100ms in this case) for the existence of an element with the given ID — i.e., to check whether the column has rendered. If not, returns true to reschedule the task. If so, renders the component and returns false to cancel the task.
We've had good luck with this in the field, so I hope it works for you too.
By the way, I was developing this as a part of answering my own question about ExtJS charting. That thread has the results of my performance testing. I was rendering 168 chart components in grid columns in 3-4s across most browsers and OSes. I imagine your sliders would render much faster than that.
Try something like this:
renderNumericFilter: function () {
var id = Ext.id();
Ext.defer(function () {
Ext.widget('slider', {
renderTo: id,
width: 200,
value: 50,
increment: 10,
minValue: 0,
maxValue: 100,
});
}, 50);
return Ext.String.format('<div id="{0}"></div>', id);
}
But I must say whatever you're trying to do - it doesn't sound right :) I don't think a bunch of sliders inside the grid will look good to the user.
