I have a grid, a tree grid and a drop drag functionality in extjs4.
The tree grid is populated by an ajax json request but when I drop and drag a record from the grid to the tree, the parent node that is added to the tree grid acts asynchronously and fires an ajax request when clicked. The problem is the parameters on the ajax request do not indicate the parent node.
Does anyone have a solution to pass parameters correctly on a asynchronous node or to convert an asynchronous node to a static tree node.
I have created the below js fiddle to replicate the issue.
http://jsfiddle.net/mgill21/3HJXX/2/
Ext.create('Ext.data.Store', {
model: 'Apps.demo.model.Resource',
autoLoad: true,
proxy: {
type: 'ajax',
url: '/echo/json/',
actionMethods: {
read: 'POST'
},
extraParams: {
json: Ext.JSON.encode(myData)
},
delay: 0
}
});
Try in your data drag item with:
var myData = [
{
name: "Rec 0",
type: "0",
children : []
},
...
];
it's work to me.
Thanks for the help. For info, i fixed this issue by setting the dragged nodes to loaded:true.
Nodes are loaded if their flag "loaded" is not true and if "leaf" is not true. Leaf property is public but "loaded" not. I set "loaded" to true on drops where needed.

I have this code:
Ext.define('storeBusiness',{
extend: 'Ext.data.Store',
autoLoad: true,
autoSync: true,
model: 'Business',
proxy: {
type: 'ajax',
api: {
read: '../crud/ler_filter.php?db='+database+'&tbl=mercados',
create: '../crud/criar.php?db='+database+'&tbl=mercados',
update: '../crud/update.php?db='+database+'&tbl=mercados',
destroy: '../crud/apagar.php?db='+database+'&tbl=mercados'
},
reader: {
type: 'json',
root: 'rows'
},
writer: {
type:'json'
}
}
});
var storeBusinessCombo = Ext.create('storeBusiness');
var storeBusiness = Ext.create('storeBusiness');
storeBusiness.add({id: 0, business: "All"});
I have 2 grids. One has storeBusiness and the other has storeProducts.
The way the work is when I click on the business grid it filters the produts grid so that it shows the products of that business.
On the business grid it has the storeBusiness that it fetches the records from a database. I want to fetch all business from the database and add one more record (named 'All') without writing it to the database.
I dont want to add 'All' to the database because in the Product's grid I want to have a combobox that has all the business (storeBusinessCombo) without the 'All' record.
Does anyone has any idea how I can do this?
(the code above isn't doing what I want, storeBusiness shows all business without the 'All' in the grid)
Important: This works if the Ext.define('storeBusiness', has a proxy that is of type: 'memory'
Two approaches come to mind:
Add the "all" record to the store after load and don't sync so the
record isn't sent to the server.
Use memory proxy, retrieve the
businesses records via Ajax request and assign them to the store via its data config.
To resolve this I have done:
Put the Ext.define('storeBusiness',{ to autoLoad: false,
Put this code:
var storeBusinessCombo = Ext.create('storeBusiness', {autoLoad: true});
var storeBusiness = Ext.create('storeBusiness');
storeBusiness.on('beforeload', function(){
storeBusiness.loadData([{id: 0, business: "All"}]);
}
And you should put
storeBusiness.load({addRecords: true});
when you want to load storeBusiness.
Filter parameter value i.e name value is not included when i was performing filter operation in my API call as written below
_dc:1427270031651
counrtyId:2
custId:1
id:
name:
page:1
start:0
limit:10
sort:[{"property" : "id", "direction" : "desc"}]
This is my store
Ext.define('MyDesktop.store.DirectoriesStore', {
extend: 'Ext.data.Store',
requires:'MyDesktop.model.DirectoriesNumberModel',
model: 'MyDesktop.model.DirectoriesModel',
storeId:'DirectoriesStore',
autoLoad : {
params : {
start : 0,
limit : '10'
}
},
pageSize : 10,
remoteSort : true,
sorters : [{
property : 'id',
direction : 'desc'
}],
remoteFilter : true,
proxy:{
type:'ajax',
url:'./configuration/directory/get',
reader:{
type: 'json',
root: 'data',
totalProperty: 'total'
},
extraParams: {
'countryId': '',
'custId': ''
}
},
autoLoad:false
});
and this is my view
Ext.require([
'Ext.ux.grid.FiltersFeature'
]);
var filters = {
ftype: 'filters',
local: true,
features: [{type: 'integer',dataIndex: 'name'},
{type: 'string',dataIndex: 'description'},
{type: 'string',dataIndex: 'fileName'}]
};
and I added it grid as follows:
features: [filters],
Filters are working but In API call filters are not calling
Please anyone help me.
You have remote filtering disabled in your store.
Change remoteFilter: false to remoteFilter: true and try again.
From the docs:
remoteFilter : Boolean
true to defer any filtering operation to the server. If false,
filtering is done locally on the client.
It also appears that your specifically telling your application to apply the filters locally with the local:true config.
The problem is, the params are not being sent to the ajax call. But hey, try changing the page after you loaded your store. Then try sorting again. You will see that the params are now being sent along in the Ajax request.
My current workaround is to imitate a changepage via gridStore.loadPage(page, [options]). You should also change it back to first page again after that.
After you change the page, sort will be working for all following requests.
This of course is just a workaround and we may have different requirements. My grid is calling store.load() after render so I attached the change page there.
Hope you have some hints.
NOTE: THIS IS ONLY A WORKAROUND!
I have a tree folder structure that I am displaying in a webpage using Fancytree and using the lazyLoad option to display the contents of the folder ondemand. This works fine for the first time, but if there are no items under a folder and when expanded, since there are no items, the icon to expand/collapse disappears. When i create some folders in at empty folder, I dont have a way to fire an ajax call again to display the new contents. Any idea how this can be achieved?
$("#officialTreeView").fancytree({
extensions: ["table"],
aria: true,
source: {
url: "myurl/jsonoutput",
data: {key: "1" },
cache: false
},
lazyLoad: function(event,data) {
var node = data.node;
//data.node.load(true);
// Issue an ajax request to load child nodes
data.result = { cache:false, url: "myurl/jsonoutput", data: {key: node.key } }
},
renderColumns: function(event, data) {
var node = data.node,
$tdList = $(node.tr).find(">td");
//console.log(node);
$tdList.eq(1).text(node.data.childcount);
}
});
You can call node.resetLazy() or node.load(true) (for example when a node is collapsed).
See http://wwwendt.de/tech/fancytree/doc/jsdoc/FancytreeNode.html for a complete list of methods.
i.e just add an event handler for collapse to your config
collapse: function(event, data){
data.node.resetLazy();
},
I have a lazy loading DynaTree in the lastest version 1.2.4 and get the challange, to provide the path to the current selected node.
I do a loop over the root nodes to build the first level of the tree. After clicking one of the root nodes, the tree expand and select via lazy loading the next elements.
Now the element in the 3rd dimension of the tree is known, but how i provide the affected nodes in the JSON structure?
A simple add to the end will also add the elements in the root tree.
$(function(){
// Attach the dynatree widget to an existing <div id="tree"> element
// and pass the tree options as an argument to the dynatree() function:
$("##tree").dynatree({
clickFolderMode: 3,
persist: false,
autoCollapse: true,
onActivate: function(node) {
// A DynaTreeNode object is passed to the activation handler
// Note: we also get this event, if persistence is on, and the page is reloaded.
if( node.data.href ){
// use href and target attributes:
window.location.href = node.data.href;
}
},
onLazyRead: function(node){
node.appendAjax({url: "#intranetpath#remote/lopTreeLoader.cfc?method=getNodes",
data: {"key": node.data.key, // Optional url arguments
"mode": "all"
},
// (Optional) use JSONP to allow cross-site-requests
// (must be supported by the server):
// dataType: "jsonp",
success: function(node) {
// Called after nodes have been created and the waiting icon was removed.
// 'this' is the options for this Ajax request
},
error: function(node, XMLHttpRequest, textStatus, errorThrown) {
// Called on error, after error icon was created.
},
cache: false // Append random '_' argument to url to prevent caching.
});
},
children: [ // Pass an array of nodes.
<cfloop query="qDivision">
{ key:"#qDivision.obj_uuid#" ,
title: "#qDivision.f_division_name#",
activate:false,
expand:#qDivision.expand#,
select:false,
isLazy:true,
<cfif qDivision.clickable>
addClass:"boldText",
href: "/program.helios/lop/index.cfm?obj_uuid=#qDivision.obj_uuid#",
</cfif>
icon:"../../skin/icons/idivision.gif"}
<cfif qDivision.currentrow NEQ qDivision.recordcount>,</cfif>
</cfloop>
]
});
});
How I can initialize the tree with all nodes in the direct path to the selected node?
A child object may in turn contain a children property:
children: [ // Pass an array of nodes.
<cfloop query="qDivision">
{ key:"#qDivision.obj_uuid#" ,
title: "#qDivision.f_division_name#",
activate:false,
children: [{title: "foo"}, ...]
I'm new to Kendo and the Kendo grid but I'm trying to learn how to use the master detail Kendo grid where the detail grid is supposed to support batch editing. The data is available in a local JavaScript object.
This jsFiddle demonstrates the problems I'm seeing.
Here's how the grid is being created - see the jsFiddle for the complete snippet -
$("#grid").kendoGrid({
dataSource: items,
detailInit: createDetail,
columns: [
{ field: "Item", width: "200px" },
]
});
function createDetail(e) {
$("<div/>")
.appendTo(e.detailCell)
.kendoGrid({
dataSource: {
batch:true,
transport: {
read: function (options) {
options.success(e.data.SubItems);
}
}
},
editable:true,
pageable:true,
toolbar: ["save", "cancel"],
columns: [
{ field: "SubItem", title: "Sub Item", width: 200 },
{ field: "Heading1", title: "Heading 1", width: 100 }
]
});
}
When you edit an item in the grid and click to the next cell, the details grid automatically collapses not matter where I click, even in an adjacent cell. When I open it again, I don't see the change indicator in the cell (red notch) but the new value is there.
If I were to hook up the save to an ajax call, Kendo sends the right detail item(s) that were edited.
Nothing happens when I click cancel changes.
How do I get the grid to not collapse and see the change indicators ?
How do I get canceling of changes to work correctly ?
[Update] - Further investigation reveals that if I use an older Kendo version 2011.3.1129 , this works as expected. But if I use the newer 2012.3.1114, it doesn't. Dont know if this is a bug or a change in behavior.
After much effort, I found that the cause seems to be that the master grid is rebinding automatically causing the behavior I observed. I was able to get around this by handling the dataBinding event in the master grid and within that, checking if any of the detail datasources were dirty and if so, calling preventDefault.
Here are relevant code snippets :
dataBinding: function (e) {
if (masterGrid.AreChangesPending()) {
e.preventDefault();
}
}
AreChangesPending : function () {
var pendingChanges = false;
// I gave each detail div an id so that I can get a "handle" to it
$('div[id^="detail_"]').each(function (index) {
var dsrc = $(this).data("kendoGrid").dataSource;
$.each(dsrc._data, function () {
if (this.dirty == true || this.isNew()) {
pendingChanges = true;
}
});
// For some reason, Kendo did not detect new rows in the isNew()
// call above, hence the check below
if (dsrc._data.length != dsrc._total) {
pendingChanges = true;
}
});
return pendingChanges;
}
