I use a simple treepanel for my application, and sometimes it stops expanding and unexpanding nodes with the next error:
records[i] is undefined
http://localhost:8080/extjs/ext-all-debug.js
Line 58763
My code is quite simple:
var tree_store = Ext.create('Ext.data.TreeStore', {
id: 'tree_store_id',
proxy: {
type: 'ajax',
url: 'tree_data.json?object_id=' + Ext.getCmp('object_id').value
},
root: {
text: 'Парки',
id: 'objectId',
expanded: true,
iconCls: 'tree-cls-root'
}
});
var tree = Ext.create('Ext.tree.Panel', {
id: 'stock_tree_id',
store: tree_store,
autoWidth: true,
height: 600,
autoScroll: true,
renderTo: document.getElementById('stock_tree_div'),
useArrows: true,
border: false,
rootVisible: true,
listeners: {
itemclick: function (view, rec, item, index, eventObj) {
document.getElementById("stock_div").innerHTML = rec.data.text;
}
}
});
Has anyone faced this problem?
May be it's problem at your JSON. Is it include something like:
"leaf" : "true",
"expanded" : "true"
?
In my case this was caused by the fact that server response json contained parent node as a first element.
So when I was expanding node 123, server was returning node 123 itself and then all of it's children.

How do I control how many rows appear in a kendo grid? Real Estate is limited, so I need to have a lot of info in a pretty compact space. I'm trying to pack everything in my grid in a 300-pixel high area.
The issue I'm having is that all 200-plus rows of data that are being returned from my MVC JsonResult in my controller are displaying at once, on a single page. Not quite exactly what I'm looking for.
Code is below, if someone a little more knowledgeable about formatting a kendo grid could help out, I'd appreciate it.
Thanks!

{}
var RemoteJsonData_Call = new kendo.data.DataSource({
transport:
{
read: {
type: "GET",
dataType: "json",
url: resourceURL_Call
},
pageSizes: 8,
serverPaging: true
},
schema: {
model: {
ScheduleData: {
extensionDataField: {
fields: {
ScheduleDate: { type: "date" },
ScheduleAmount: { type: "number" },
SchedulePrice: { type: "number" },
ScheduleNotes: { type: "string" }
}
}
}
}
}
})
$('#callSched').kendoGrid({

The problem is that you have defined that the paging is done in the server when it is not. You should say:
serverPaging: false
or just nothing since the default value is false.
With this you should have a grid with the number of pixels specified in the height option (in your example 300 pixels). Other options in you example are correct.
You have server paging and page size set up incorrectly here:
var RemoteJsonData_Call = new kendo.data.DataSource({
transport:
{
read: {
type: "GET",
dataType: "json",
url: resourceURL_Call
},
pageSizes: 8,
serverPaging: true
},
It should be:
var RemoteJsonData_Call = new kendo.data.DataSource({
transport:
{
read: {
type: "GET",
dataType: "json",
url: resourceURL_Call
}
},
pageSize: 8,
serverPaging: true
The config options were in the wrong place, and "pageSizes" was misspelled, it should be "pageSize" with no "s" on the end.

i am working in extjs4. I have created treepanel view as-
Now on clicking on node surrounding,i am retrieving its id,sending it to server side and retriving its corresponding childs. I am getting this serverside output in json format as-
{"children":[{"text":"Subgeo1","leaf":true,"expanded":false,"checked":false},{"text":"Subgeo2","leaf":true,"expanded":false,"checked":false}]}
So now i want to insert this above json elements as childs of node "surrounding". So how to update tree store with this new childs? Or how can i add childs dynamically? please help me
Here's my example how I add elements on my tree:
on_AddTreeNodes: function (win) {
var _this = this;
//your tree
var tree = win.down('treepanel[name=main_tree]');
//get tree root
var root = tree.getRootNode();
var first = root.firstChild;
var _index = first.childNodes.length - 1;
//adding folder
first.insertChild(_index, { text: 'New folder name', leaf: false });
var data = first.getChildAt(_index);
Ext.Ajax.request({
url: 'your url',
method: 'GET',
params: {
//some params
},
success: function (objServerResponse) {
//if success, you add your data from server into your tree
data.insertChild(data.firstChild, {
text: 'your leaf name',
leaf: true,
//your other params
});
});
//sync your tree store
tree.getStore().sync();
}
In my example I use insertChild - this method adding childs in my tree.
Here's some information that should help you : work with tree in ExtJs
In my view I have
Ext.applyIf(me, {
items: [
{
xtype: 'treepanel',
name: 'main_tree',
title: 'Menu',
region: 'west',
collapsible: true,
rootVisible: false,
viewConfig: {
width: 230
},
store: Ext.create('Ext.data.TreeStore', {
root: {
expanded: true,
children: [
{
text: '',
expanded: true,
children: [
{ text: 'Menu item', leaf: true, param1: 'somedata', param2: 'somedata', param3: 'somedata' },...
and when I use:
data.insertChild(data.firstChild, {
text: 'your leaf name',
leaf: true,
//your other params
});
instead '//your other params' you get params from your JSON and write like this:
data.insertChild(data.firstChild, {
text: 'your leaf name',
leaf: true,
param1: 'jsondata',
param2: 'jsondata',
param3: 'jsondata'
});
I have two lists in 2 separate tabs, both hooked up to a server side database. I'm attempting to set up list paging and on one of the lists its functioning exactly as it should be. For the other list, the model and store have all the same settings as the list that pages properly but no 'Load More..." text shows up at the bottom for this list.
With regards to the list paging plugin, both lists are basically exactly the same as each other (ie the Store, Model, 'List' view) but on one the paging just does not work. Does anyone have any idea what could possibly be causing this?
Editing with some more information:
I'm using Chrome to develop. Looking at the Network I seem to be getting JSON that looks right, for the one thats not working it's returning 8 records, and the total property returned is 13 (this makes sense because I've got my page size set to 8).
The Store from list that does NOT work

Make sure that you implement the paging logic in your server side codes. You have to supply the functionality of sending page by page. Maybe "submitSolution.php" does not send the data partially.
I have problem configuring RowExpander for my grid. When the grid renders the expander is already opened for each row and with nothing inside. When i click on its icon the following error is generated: nextBd is null. I found very similar problem here http://www.sencha.com/forum/showthread.php?185837-Grid-Panel-PlugIn-Rowexpander-nextBd-is-null but the solution does not work for me and still dont get it why plugin config cannot be passed in initComponent method:
Here is my grid code:
Ext.define('GSIP.view.plans.PlanReqList' ,{
extend: 'Ext.grid.Panel',
alias : 'widget.gsip_devplan_list',
id: 'gsip_plan_list',
plugins: [{
ptype: 'rowexpander',
rowBodyTpl : [
'Nazwa:{name}'
]
}],
//title:i18n.getMsg('gsip.view.PlanReqList.title'),
layout: 'fit',
initComponent: function() {
this.store = 'DevPlan';
// this.plugins = [{
// ptype: 'rowexpander',
// rowBodyTpl : [
// {name}
// ]
// }];
this.features = [{ftype:'filters', encode:false, local:true},{ftype:'grouping'}];
this.tbar = [{
xtype:'commandbutton',
id: 'newReq',
iconCls:'icon-application_add',
text: i18n.getMsg('gsip.view.plans.PlanReqList.addReq'),
command: 'newReq',
}];
this.viewConfig = {
forceFit:true,
getRowClass: function(record, index) {
var c = record.get('elapsedPercent');
if (c >= 0) {
return 'elapsed-normal';
}
}
}
this.columns = [
{header: "Id", dataIndex: "id", width:50, sortable: true, filter:{type:'numeric'}},
{header: i18n.getMsg('gsip.view.plans.PlanReqList.column.name'), dataIndex: "name", flex:1, sortable: true, filter:{type:'string'} },
}
];
this.callParent(arguments);
},
The rowexpander plugin makes use of a feature called rowbody.
In your initComponent() you override this.features (which already includes rowbody) with this line:
this.features = [{ftype:'filters', encode:false, local:true},{ftype:'grouping'}];
Thus the rowbody feature is not included; thus the .x-grid-rowbody-tr class is not injected; thus rowexpander can't find such class for nextBd and returns null.
You should try:
var iNewFeatures = [{ftype:'filters', encode:false, local:true},{ftype:'grouping'}];
this.features = iNewFeatures.concat( this.features );
Lastly, plugins cannot be initiated in InitComponent(), you can either declare them as configs, or within the constructor. See this thread for more info.
I am using a grid panel in which I need to make a column as a link(It should look like link-with no action). I am using listener in the gridpanel and on click of a cell its working fine. Only thing is 1st column should look like a link. But how to put href="#" I am not sure. This is my code:
var addressDetailsStore = Ext.create('Ext.data.Store', {
id:'addressDetailsStore',
autoLoad: true,
fields:
[
'addressType',
'street1',
'street2',
'province',
'city',
'country'
],
proxy: {
type: 'ajax',
url: 'resources/json/addressDetails.json', // url that will load data with respect to start and limit params
reader: {
type: 'json',
root: 'items',
}
}
});
Ext.define('iOMS.view.common.addressView', {
extend: 'Ext.grid.Panel',
alias: 'widget.AddressViewPanel',
layout: 'fit',
collapsible: true,
title:'Address',
store: addressDetailsStore,
listeners:{
cellclick:function (iView, iCellEl, iColIdx, iRecord, iRowEl, iRowIdx, iEvent){
// Getting the event and I am doing logic here..
}
I just want 'addressType' columns appear like a link and I dont know where to put href...
Thanks for your responses.

You could also use a template column:
columns: [
{ text: 'External Link', xtype: 'templatecolumn', tpl: '{title}'}
]
You can specify the columns you want, and for the column with just a link, add a renderer. This example might help you.
var template = new Ext.XTemplate(
' ').compile();
columns:[
{
header: "",
renderer: function () {
return template.applyTemplate();
}
},
You can use renderer function like as follow
columns: [
{
header: 'number',
dataIndex: 'number',
flex: 1,
renderer: function(number) {
return Ext.String.format('{0}', number);
}
},
