ExtJS4 grid grouping header renderer - How to specify? - grid

Anyone know how to attach a renderer to a grid grouping header in ExtJS4? In ExtJS3 I have the following working code, which returns 'Past' if an event has been completed ('Y'), or 'Upcoming' if not completed:
function fmt_group_heading(groupVal) {
if (groupVal === 'Y') {
return 'Past';
} else {
return 'Upcoming';
}
}
// create the Grid
var fitGrid = new Ext.grid.GridPanel({
store: fitGroupingStore,
columns: [
{header: "ID", dataIndex: 'id', hidden: true },
{header: 'Event', width:320, dataIndex: 'event',
renderer:fmt_event_description},
{header: 'Events', dataIndex: 'completed', hidden: true,
renderer: fmt_group_heading }
],
stripeRows: true,
// config options for stateful behavior
stateful: true,
stateId: 'grid',
hideHeaders: true,
view: new Ext.grid.GroupingView({
groupRenderer: 'completed',
forceFit: true
})
});
ExtJS4 provides grid grouping but I'm not understanding how to change the output of the group text. The 'groupHeaderTpl' attribute of Ext.grid.feature.Grouping seems to only take the raw field value as read from the store.
this.groupingFeature = Ext.create('Ext.grid.feature.Grouping', {
groupHeaderTpl: 'Group: {completed}'
});
// create the Grid
this.fitnessGrid = new Ext.grid.Panel({
store: this.fitnessEventStore,
features: [this.groupingFeature],
// etc.......

try smth like this:
groupHeaderTpl:
'{[fmt_group_heading(values.name)]}
({rows.length}
Item{[values.rows.length > 1 ? "s" :
""]})'

The groupHeaderTpl requires you to use {name} when composing the template. It will only use the value provided by the groupField.
See the Docs.

Try this:
groupHeaderTpl: '{[values.rows[0].completed]}'

There is one concern regarding angular UI-grid

I want to display only 4 columns, but when I bind the grdOptions.Data=entity,
then all fields in entity are converted into a column. Can we prevent it from autogenerating all the columns?
As per the first page of documentation:
... if you wanted to configure the core ui-grid, you might choose to set some options and columns on your grid (the documentation for these is found in gridOptions and columnDef.
And here's the first example:
$scope.gridOptions = {
enableSorting: true,
columnDefs: [
{ name: 'field1', enableSorting: false },
{ name: 'field2' },
{ name: 'field3', visible: false }
]
};

Unable to set value of a textfield because its not in scope

I have a panel where in I have a button in the header which helps me to add two textfields in that panel. Now when I click on this button it takes me to a popup form where the user enters the value of the two textfields it wants and then clicks on save button in the header of this popup panel.
The two textfields are added but the value is not set to the value which is entered in the popup form. I think the problem is with the scope. Kindly look at the following code and tell me how to resolve this issue.
xtype: "panel",
id: 'idFieldpanel',
...
header:{
titlePosition: 0,
items:[{
xtype:'button',
text: 'Add',
handler: function(){
var addidFieldPanel= new Ext.form.Panel({
id: 'newidFieldPanel',
width: 250,
height: 100,
floating: true,
closable : true,
layout : {
type : 'vbox',
align : 'stretch'
},
bodyPadding: 10,
items : [
{
xtype : 'textfield',
id : 'newidFieldname',
fieldLabel : 'Name',
name : 'newidFieldname',
flex : 1,
scope : this
},
{
xtype : 'textfield',
id : 'newidFielddataType',
fieldLabel : 'DataType',
name : 'newidFielddataType',
flex : 1,
scope : this
}
],
header : {
titlePosition : 1,
items : [{
xtype: 'button',
text: 'Save',
handler: function() {
ctr++; //this is used so that the id of the added fields do not match and hence they do not overlap
Ext.getCmp('idFieldpanel').add({
xtype:"container",
layout : {
type : 'hbox',
align : 'stretch'
},
defaults: {
bodyPadding: 10,
margin: '10 0 10 10'
},
items: [
{
xtype : 'textfield',
fieldLabel: 'Name',
id: 'idFieldName' + ctr,
name : 'Data',
margin:'0 10 10 0',
flex : 1,
height : 'auto'
},
{
xtype : 'textfield',
fieldLabel: 'Datatype',
name : 'Type',
id: 'idFielddataType' + ctr,
margin: '0 10 10 0',
flex : 1,
height : 'auto'
}
]
});
Ext.getCmp('idFieldName' + ctr).setValue(Ext.getCmp('newidFieldname').getValue());
Ext.getCmp('idFielddataType' + ctr).setValue(Ext.getCmp('newidFielddataType').getValue());
}
}]
}
})
addidFieldPanel.show();
}
}]
}
There are a few things that can help you out here, but first would be to not bother with tracking unique ID's across your components. Let ExtJS handle that for you. Also, removing the nested handlers will make your code a lot easier to read. I put together this fiddle that shows how you can do that.
By not using ID's you can grab reference to parent/child components with the up/down selectors similar to saveBtn.up('panel').
You can also add a form to your popup for easier selecting. Hope this helps to give you an idea of a better way to leverage the framework.

dojo datagrid first loading issue

Hi guys I have a dojo datagrid inside a TabContainer/BorderContainer/ContentPane
The datagrid is render progammatically, the code is:
<script>
require(['dojo/request',
'dojo/dom',
'dijit/Dialog',
'dojo/date/locale',
'dojo/_base/array',
'dojo/store/Memory',

function(request,dom,Dialog,locale,array,Memory, ObjectStore,Button,domClass,DataGrid, ItemFileWriteStore, xhr,cells,cellsDijit,date,stamp, locale,currency,localeCurrency, DateTextBox, CurrencyTextBox,ready){
var dataStore1 = new ObjectStore({ objectStore:new Memory({ data: <?php echo json_encode($constructiondrawingsdata) ?> }) });
var layout1 = [{
defaultCell: { width: 8, editable: false, type: cells._Widget, styles: 'text-align: center;' },
cells: [
{name: 'TYPE', field: 'filepath' ,formatter: displayIcon ,width:3},
{name: 'ID', field: 'id' ,width:2},
{name: 'PROJECT', field: 'project' ,width:5},
{name: 'USER', field: 'user' ,width:8},

]
}];
var grid1 = new DataGrid({
id: 'grid1',
query: { id: "*" },
store: dataStore1,
structure: layout1,
loadingMessage: "Loading data...",
noDataMessage : "No results found",
clientSort: 'false',
style: "height: 100%; width: 100%",
canSort: function(col) { return col != 1; },
selectionMode:'single',
rowSelector: '0px'});
grid1.placeAt("gridDiv1");
</script>
<div data-dojo-type="dijit/layout/BorderContainer" style="padding:0px" data-dojo-props="liveSplitters: true, design: 'headline'">
<div id="gridDiv1" data-dojo-type="dijit/layout/ContentPane" data-dojo-props="region:'center'">
</div>
</div>
The problem is , when I load the datagrid the first time I only get 7 rows from the database of a total of 9 rows, and then when I refresh the datagrid I get the 9 rows.
Moreover if I press F12 in Google Chrome to see the console and I close it I lose again the last 2 rows of the datagrid (it´s weird right?).
Again if I refresh the datagrid I get the 9 rows.
Anyone has faced this issue?. Thanks in advance

Highcharts - Maps data structure

I am trying to build an array of data returned from a third party API, and display it using the Highcharts map module.
I've done so with the charts module, using line and pie charts both with not much difficulty. Now that I've moved onto maps, I seem to be running into a bit of difficulty. It was quite clear from the examples provided how the data should be structured to be properly read by Highcharts.
When it comes to the maps module, the data structure is not clear at all. How would I structure my data to pass into my Highcharts map???
[ 'US' , 'United States' , 32 ] , [ 'CA' , 'Canada' , 100 ]
If I use the provided :
jQuery.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=world-population-density.json&callback=?', function (data) {
console.log(data);
// Initiate the chart
jQuery('#geo_map').highcharts('Map', {
title : {
text : 'Campaign Link Clicks Around The World'
},
mapNavigation: {
enabled: true,
buttonOptions: {
verticalAlign: 'bottom'
}
},
colorAxis: {
min: 1,
max: 1000,
type: 'logarithmic'
},
series : [{
data : data,
mapData: Highcharts.maps['custom/world'],
joinBy: ['iso-a2', 'code'],
name: 'Population density',
states: {
hover: {
color: '#BADA55'
}
},
tooltip: {
valueSuffix: '/km²'
},
}],
credits: {
enabled: false
},
});
});
});
It works. But I can't seem to figure out how to pass in my data. I thought it was as simple as
[ 'Abbreviation' , 'Name' , Value ] , [ 'Abbreviation' , 'Name' , Value ]
but clearly not. The documentation isn't very clear on data structure.
Thanks.

How can I use a custom gif loader for Lists in Sencha Touch?

When you use the Ext.dataview.List in Sencha, it automatically inserts a nice loading spinner while the data is loading. That's all fine and dandy, but I'd like to know how to use a custom loader .gif.
I've looked around and think I need to change the loadmask but not positive cause I'm new to this. See this link.
Below is the code for one of my Lists. I'm hoping to be able to add the code suggested to one place so that all lists are affected and have the new spinner.
{
xtype: 'list',
height: '',
id: 'categoryList',
itemId: '',
width: '100%',
scrollable: false,
emptyText: '<div class="pdtsListHtml" style="margin-top:30%">Product List Empty</div>',
itemTpl: [
'<div ><div class="pdtsListHtml" style="display:inline;">{navigationElementItemName} ({navigationElementItemRecordCounts})</div><div style="display:inline;float:right;margin-right:5px;"><img src="resources/image/arrow.png" width="11" height="11"></div></div>'
],
store: 'productListStore',
allowDeselect: true,
onItemDisclosure: false
}
Here's a fiddle that shows you an example list with a loading mask that uses a gif.
Basically you should define your own Ext.LoadMask subclass and use it on the list:
Ext.define("Test.MyLoadMask", {
extend: "Ext.LoadMask",
alias: "widget.myloadmask",
getTemplate: function() {
var prefix = Ext.baseCSSPrefix;
return [
{
reference: 'innerElement',
cls: prefix + 'mask-inner',
children: [
{
reference: 'indicatorElement',
cls: prefix + 'loading-spinner-outer',
children: [
{ tag: 'img', src: "http://example.com/my-spinner.gif" }
]
},
{
reference: 'messageElement'
}
]
}
];
}
});
Then you should define an applyMasked on your lists that modifies the xtype and sets it to myloadmask instead of loadmask.
