In an angular app I have a page that displays several Kendo-grids based on the data retrieved from an http request. The data comes back as json.
This is the function that executes on successful data retrieval. This is within a controller, and ctrl is the "this" object on the controller scope. Moment is a JavaScript library for managing dates. The only thing it's doing here is formatting as strings the date (MM/DD/YYYY) and the time (hh:mm A).
function (data) {
ctrl.dateGroups = {};
var currentDate = '';
data.Data.forEach(function (item) {
item.Date = item.StartDateTime ? moment(item.StartDateTime).format(HC_APP_CONFIG.dateFormat) : '';
item.ClockInTime = item.StartDateTime ? moment(item.StartDateTime).format(HC_APP_CONFIG.timeFormat) : '';
if ( angular.isEmpty(item.EndDateTime) ||
item.EndDateTime === '' ||
item.EndDateTime.format(HC_APP_CONFIG.dateFormat).match(HC_APP_CONFIG.badLocalDatePattern) !== null ){
item.ClockOutTime = '';
item.EndDateTime = '';
} else {
item.ClockOutTime = moment(item.EndDateTime).format(HC_APP_CONFIG.timeFormat);
}
var currentDate = 'd'+item.Date;
if (ctrl.dateGroups.hasOwnProperty(currentDate) &&
ctrl.dateGroups[currentDate].length > 0) {
ctrl.dateGroups[currentDate].push(item);
} else {
ctrl.dateGroups[currentDate] = [item];
}
});
}
The function (successfully) takes each returned item and puts it into an object as part of arrays named after the date, so that all items from Jan 14th, for example, end up in one array, and another for Jan 15th, etc.
This displays in the page with this loop:
<div class="col-sm-12" ng-repeat="(key,value) in punchList.dateGroups">
<h2 class="punch-heading">{{key.substring(1)}}</h2>
<div hc-grid id="grid-{{key}}"></div>
</div>
The result is a series of grids, each corresponding to a date and containing all the items for that date. This again, is successful.
The grid configuration:
gridConfig = {
uiOptions: {},
autoBind: false,
sortable: {
mode: 'single'
},
height: 'auto',
columnMenu: false,
filterable: false,
dataSource: {
type: 'json',
serverPaging: true,
serverFiltering: true,
serverSorting: true,
pageSize: HC_APP_CONFIG.defaultPageSize,
schema: {
data: 'Data',
total: 'TotalCount',
model: {
id: 'ShiftId',
fields: {
EmployeeName: {
type: 'string'
},
EmployeeCode: {
type: 'string'
},
JobName: {
type: 'string'
},
ClockIn: {
type: 'string'
},
ClockOut: {
type: 'string'
}
}
}
}
},
columns: [
{
field: 'EmployeeName',
title: 'Name',
sortable: false
},
{
field: 'EmployeeCode',
title: 'Employee Code',
sortable: false
},
{
field: 'JobName',
title: 'Job',
sortable: false
},
{
field: 'ClockInTime',
title: 'Clock In'
},
{
field: 'ClockOutTime',
title: 'Clock Out'
}
]
}
The problem is when I sort by the Clock In or Clock Out columns (the only sortable columns). At this point, the grid structure (pagination indicator, column heads, etc) remain in tact but the data disappears.
I'm using Kendo UI v2015.1.429
Kendo UI grids support direct server interaction via a built-in AJAX system for making API calls. It appears that setting serverSort:true may tell the Kendo UI grid to drop the current data model and query the server for newly sorted data (which it expects the server to provide). Since you are not using direct server interaction with the grid, it probably drops the model but then has no way to get a new one.
There is a sortable:true option that may be what you need for client side sorting of the existing data.
Link to Kendo UI grid server-side sorting article
We are using kendo drag and drop functionality inside the kendo grid table.
1) If the user provide data on any editable fields and without saving the data, if user click/jump to other field for edit. User is loosing his updated data.
2) If the user update any records, we are refresh/regenerate table again Or if we refresh/regenerate outside from the function Or we added new records using outside the function. After that user are not able to drop row to replace with other.

];

I've run into similar issue some time ago. And also I found the following thread on their forum - http://www.kendoui.com/forums/ui/grid/drag-and-drop-reordering.aspx#boD2qq6aG2OF1P8AAFTdxQ
So if you add one more additional column to the table and put an image there or some other element, then you'll be able to use that element as draggable target like:
grid.table.kendoDraggable({
filter: "tbody > .draggableTarget".....
The table is completely recreated in the DOM in the case when you refresh it, so you have to resubscribe your drag and drop functionality.
I was having similar issues using the newer kendoSortable with an editable grid to achieve drag/drop row sorting.
This fiddle http://jsfiddle.net/UsCFK/273/ works.
It uses a column with a drag handle as mentioned above to prevent cell edits being lost - the other cells are ignored in the setup:
grid.table.kendoSortable({
filter: ">tbody >tr",
hint: $.noop,
cursor: "move",
ignore: "TD, input",
placeholder: function (element) {
return element.clone().addClass("k-state-hover").css("opacity", 0.65);
},
container: '#grid tbody',
change: onGridRowChange
});
It also updates the position field in the datasource, rather than removing, then re-inserting the row as in some other examples - as this will cause a delete request request to the server for each row that is moved - which can cause issues when clicking the batch-editing cancel button. The position field is only shown for demonstration purposes - it should not be exposed for manual editing.
I have am currently using Dojo EnhancedGrid with Pagination, filtering and cell edition.
The problem is that in one page, I need to update another value when a cell is edited. When I update this value, I loose the cell selected so I need to click on the next cell to select it and modify it.
It is so not possible to do Enter / edit / enter / down / enter / edit (Excel like edition).
Here is a part of my code :
var store = new dojo.data.ItemFileWriteStore({'data':data});
var grid = new dojox.grid.EnhancedGrid({
id: 'grid',
store: store,
structure: structure,
columnReordering: true,
autoHeight: true,
autoWidth: true,
initialWidth: '100%',
escapeHTMLInData: false,
plugins: {
pagination: {
pageSizes: ["10", "25", "50", "All"],
description: true,
sizeSwitch: true,
pageStepper: true,
gotoButton: true,
maxPageStep: 4,
position: "bottom"
},
filter : {}
},
onStartEdit: function(inCell, inRowIndex)
{
item = grid.selection.getSelected()[0];
currentVal = item[inCell['field']][0];
},
doApplyCellEdit: function(inValue, inRowIndex, inAttrName) {
if(inValue != currentVal){
[...]
$.ajax(url, data, {
success:function(data, textStatus) {
val = parseInt(data["info"]);
if(!isNaN(val)) {
grid.store.setValue(item, 'info', val);
grid.update();
} else {
grid.store.setValue(item, 'info', 0);
grid.update();
}
}
});
}
}
});
dojo.byId("gridDiv").appendChild(grid.domNode);
grid.startup();
Do you see any solution to handle this ?
I too use an enhanced dojo grid, where I had a similar problem. I used this to reload the data right:
require(["dijit/registry"],function(registry) {
var grid = registry.byId('grid');
grid._lastScrollTop=grid.scrollTop;
grid._refresh();
});
With this you always should get the last row you manipulated, and eventually also the last selected one... .
After many research, I have found the following solution :
$.ajax(url, data, {
success:function(data, textStatus) {
val = parseInt(data["info"]);
if(!isNaN(val)) {
grid.store.setValue(item, 'info', val);
grid.update();
window.setTimeout(function() {
grid.focus.next();
}, 10);
} else {
grid.store.setValue(item, 'info', 0);
grid.update();
window.setTimeout(function() {
grid.focus.next();
}, 10);
}
}
});
The timer is needed because there is a short delay before grid update the thus loosing the focus.
I want to check the one of these fields which are ' Adet', 'toplam' whether they are updated or not when button is clicked but i dont know how can i do it? thanks
//regarding fields
{
header: dil('Adet'),
width: 30,
sortable: true,
dataIndex: 'adet',
editor: new Ext.form.NumberField({
enableKeyEvents : true,

allowNegative: false,

})
},{
header: dil('Toplam'),
width: 30,
sortable: true,
renderer: function(v, params, record){
return Ext.util.Format.usMoney(record.data.fiyat * record.data.adet);
},
dataIndex: 'toplam',
summaryType: 'totalCost',
summaryRenderer: Ext.util.Format.usMoney
}
// check area
handler: function(){
//commente alındı
// fileGrid_yp_is.el.mask(dil('Lütfen Bekleyiniz...'), 'x-mask-loading');
var il_id = Ext.getCmp('il_global25').getValue();
var sap_no = Ext.getCmp('ila-sapno-id25').getValue();
if(il_id == '' || sap_no == '' // this area code will be added) {
Ext.Msg.alert(dil("Dikkat"),dil("Lütfen zorunlu alanları doldurunuz"));
return false;
}}
You can archive this with the dirtychange event. The second param will be true if the value has been changed or false if not. The event will also only fire once a state change.
A second variant is the isModified(fieldName) method of a model. It will return true ich the submitted field has been changed since the last load or commit.
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.
