I'm trying to get a Dojo datagrid working - I have replicated the first example on the documentation page (http://docs.dojocampus.org/dojox/grid/DataGrid) & it works just fine.
However, when I try to display the grid inside another div (i.e. putting 'gridContainer4' from the example inside any other div) nothing displays...
Any help would be much appreciated - can't find anything about this anywhere online!
Finally figured it out:
The example text creates the new dojox.grid.DataGrid and applies it to "document.createElement('div')" - changing this to the ID of an existing div fixed the problem (rather than appendChild-ing it to another div)
Original code:
var grid4 = new dojox.grid.DataGrid({
query: {
Title: '*'
},
store: store4,
clientSort: true,
rowSelector: '20px',
structure: layout4
}, document.createElement('div'));
changes to:
var grid4 = new dojox.grid.DataGrid({
query: {
Title: '*'
},
store: store4,
clientSort: true,
rowSelector: '20px',
structure: layout4
}, "gridContainer4");

I am working on dojo enhanced grid view. I am able to display the grid in UI. But AnyColumn option is added as new column.
Example:
Any help will be appreciated...
Here is the Code
var mygrid = new EnhancedGrid({
id: "grid",
store: gridStore, //Data store passed as input
structure: gridStructure, //Column structure passed as input
autoHeight: true,
autoWidth: true,
initialWidth: width,
canSort : true,
plugins: {
filter: {
//Filter operation
isServerSide: true,
disabledConditions : {"anycolumn" : ["equal","less","lessEqual","larger","largerEqual","contains","startsWith","endsWith","equalTo","notContains","notEqualTo","notStartsWith","notEndsWith"]},
setupFilterQuery: function(commands, request){
if(commands.filter && commands.enable){
//filter operation
}
}
}
}, dojo.byId("mydatagrid"));
mygrid.startup();
Thanks,
Lishanth
First, do not use EnhancedGrid, instead use either dgrid or gridx.
I think by default anycolumn is added to the dropdown. If you want to remove then, I would suggest to
Register for click event on the filter definition
Iterate through the drop-down and remove the first entry which is anyColumn
or you can also try something like
dojo.forEach(this.yourgrid.pluginMgr.getPlugin('filter').filterDefDialog._cboxes, function(dropdownbox) {
dropdownbox._colSelect.removeOption(dropdownbox.options[0]);
});
Updated answer is. I know this is not the elegant way of doing it but it works.
//reason why I'm showing the dialog is that _cboxes of the filter are empty initially.
dijit.byId('grid').plugin('filter').filterDefDialog.showDialog();
dojo.forEach(dijit.byId('grid').pluginMgr.getPlugin('filter').filterDefDialog._cboxes, function(dropdownbox) {
var theSelect = dropdownbox._colSelect;
theSelect.removeOption(theSelect.options[0]);
});
//Closing the dialog after removing Any Column
dijit.byId('grid').plugin('filter').filterDefDialog.closeDialog();
I'm using extjs4 and I'm trying to create a tab panel, that each tab has a different grid that loads data from a store. (each grid different store)
I would like to load the particular store only when the user clicks on the respective tab.
I don't see how I can catch the user click on the panel.
How I can do that?
I had a similar performance loading issue and failed to solve it with deferredRender. You have to add the event activate for the tab you want to load when the tab is activated :
{
title: 'tab2',
bodyPadding: 10,
html : 'A simple tab',
listeners: {
'activate' : function(){
store2.load();
},
}
}
Worked fine for me even if it's a temporary solution. Extjs 4.1 should improve loading/rendering performances. We'll see.
You can activate the panel by placing setActiveItem() in tab handler.
Ok, I figured out, I just needed to have deferredRender=true and to add the respective store.load() on the beforerender event on every tab:
var lowerTabPanel = Ext.create('Ext.tab.Panel', {
deferredRender: true,
items: [
{
title: 'tab1',
bodyPadding: 10,
html : 'A simple tab',
listeners: {
'beforerender' : function(){
store1.load();
},
}
},
{
title: 'tab2',
bodyPadding: 10,
html : 'A simple tab',
listeners: {
'beforerender' : function(){
store2.load();
},
}
},
]
});
Ext.TabPanel has config option deferredRender. May be it helps you.
Documentation:
true by default to defer the rendering of child items to the browsers DOM until a tab is activated. false will render all contained items as soon as the layout is rendered. If there is a significant amount of content or a lot of heavy controls being rendered into panels that are not displayed by default, setting this to true might improve performance.
Update: Also look at autoLoad config option in Ext.data.JsonStore, it should be false.
i have a panel which should show the "description" field of "currently activeitem of nestedlist". nestedlist uses the model having fields:
id
text
description
when user taps on any item of nestedList [on selectionchange OR itemtap&backtap], i want to change description in the panel with description of "currently activeItem of nestedList".
Is this possible?
thanks for any help/solution/pointer.
The same problem I had today, and no solution had been found with a nested list, because no single field can be taken from a Ext.data.TreeStore. One solution could be that you have lots of "if-function 'do with all the ID's and then you give each ID a text. But that's not good.
I've decided to make a simple list.
if you want I can show you my solution for the simple list
ps.: I use Sencha Touch 1.1
Update:
NotesApp.views.NaviList = new Ext.List({
fullscreen: true,
flex: 1,
layout: 'card',
scroll: false,
useToolbar: false,
itemTpl: '{text}',
store: store,
listeners: {
itemtap: function (obj, idx, el, e) {
var record = this.store.getAt(idx);
var tle = record.get('text');
index = record.get('index');
NotesApp.views.notesListContainer.setActiveItem(index, { type: 'slide', direction: 'left' });
}
}
}
});
description:
My App has the name: "NotesApp".
"notesListContainer" is a Container where all my List are displayed. "index" is an ID that I get from the store and the calls list.
Now when you tap on my NaviList you set a new ActiveItem in this Container.
thanks a lot for the reply. I also tried using simple list with one Ext.button(back button in case of nestedlist). On itemtap and buttonclink, i change list's content by
var t = new Ext.data.Store and list.setStore(t).
Please let me know if there is any other better option to do it.
var gusersPanel = Ext.create('Ext.grid.Panel', {
flex:1,
columns: [{
header: 'User Login',
dataIndex: 'user_login',
width:150
},{
header: 'User Name',
dataIndex: 'user_nicename',
width:150
},{
header:'Privledge',
dataIndex:'admin',

Hi I am using above code for the grid Panel in Extjs4.0.2a When I populate data dynamically in the store the scrollbars are not working .
I have also tried using doLayout() for grid Panel but dosent work too .
The grid Panel is in a Window .
Anything that can solve this problem ?
Actually it works for some time but dosen't work all the time .
I've had the same problem. They use custom scrollbar and it's pretty buggy (especialy in chrome). If you are not going to use infinite scroll the possible solution could be to remove custom scrollbar and use native one. To do that just add the following to the grid's config:
var gusersPanel = Ext.create('Ext.grid.Panel', {
scroll : false,
viewConfig : {
style : { overflow: 'auto', overflowX: 'hidden' }
},
// ...
});
I did gusersPanel.determineScrollbars() when i am adding and removing data from store and it is working fine .
The problem with this is the scroll listener is attached to the div element on the afterrender event, but then if the scrollbar is not needed after a layout operation the div element is removed from the dom. Then, when it's needed again it's added back, but only if enough time has passed the garbage collection makes extjs recreate the div node and this time it's added to the dom without attaching the scroll listener again. The following code solves the problem:
Ext.override(Ext.grid.Scroller, {
onAdded: function() {
this.callParent(arguments);
var me = this;
if (me.scrollEl) {
me.mun(me.scrollEl, 'scroll', me.onElScroll, me);
me.mon(me.scrollEl, 'scroll', me.onElScroll, me);
}
}
});
You written code to layout: 'fit'. It did not work autoScroll.
Change the code to some height and remove layout: 'fit' code.
Like this.
var gusersPanel = Ext.create('Ext.grid.Panel', {
flex:1,
columns: [{
...........
}],
autoScroll: true,
//layout:'fit',
height: 130,
selModel: gusersSel,
store: gusersStore
It is help you. Cheers.
I'm trying to create programatically an EnahncedGrid with a menu. I've got the grid to work, but I've been unable to use the menu. It just not shows up. The code is as follows:
<script>
sMenu = new dijit.Menu({});
sMenu.addChild(new dijit.MenuItem({
label: "Delete Record",
iconClass: "dijitEditorIcon dijitEditorIconCancel",
onClick : function(){
alert(1);
}
}));
sMenu.startup();
/**
* El grid propiamente dicho
*/
var grid = new dojox.grid.EnhancedGrid({
id: "grid_"+i,
query: {
idDocument: '*'
},
plugins: {
nestedSorting: true,
indirectSelection: true,
menus: {rowMenu:sMenu}
},
onRowDblClick: openFile,
structure: layout
})
</script>
Any idea what I'm doing wrong?
I haven't used this myself, but I have two possible suggestions:
First, make sure you're dojo.require-ing "dojox.grid.enhanced.plugins.Menu" and are only instantiating the widgets within a dojo.addOnLoad or dojo.ready.
If you've already done that, the second thing I'd suggest is giving your menu an id, and passing that id to the rowMenu property of the menus object (in other words, pass a string, not the widget itself). Although, the way you're doing it seems like it should work, judging from the code.
You can see a test page with working menus here: http://archive.dojotoolkit.org/nightly/dojotoolkit/dojox/grid/tests/enhanced/test_enhanced_grid_menus.html
