Kendo UI custom grid popup editor window only opens once

I would like to use a custom window as popup editor of a Kendo UI Grid. Its content will be complex with search fields and a grid to display search results. To do that, I don't want to use the Kendo template mechanism but a real popup window.
While doing tests with custom editor I faced an issue. Even with a very basic and simple scenario (just the create command), I'm only able to open the editor once. The second time I get an error, the editor doesn't show up anymore and the grid becomes empty.
Here is my HTML code :
<div id="main-content">
<div id="custom-window">
</div>
<table id="my-table-grid">
</table>
</div>
The JavaScript part :
function openCustomWindow(e) {
e.preventDefault();
myWindow.center().open();
}
function editorWindowClosed(e) {
myGrid.cancelRow();
}
var myWindow = $("#custom-window").kendoWindow({
modal: true,
resizable: false,
title: "Test",
visible: false,
close: editorWindowClosed
}).data("kendoWindow");
var dummyDataSource = new kendo.data.DataSource(
{
schema : {
model : {
id: "id",
fields: {
postion: { type: "number"},
name: { type: "string"},
}
}
}
});
dummyDataSource.add({postion: 1, name: "gswin"});
var myGrid = $("#my-table-grid").kendoGrid({
dataSource: dummyDataSource,
toolbar: [ {
name: "create",
text: "Create"
} ],
editable: {
mode: "popup",
window: {
animation: false,
open: openCustomWindow,
}
},
columns: [
{
field: "postion",
title: "Postion"
},
{
field: "name",
title: "Name"
}
]
}).data("kendoGrid");
The error message in the JavaScript console :
Uncaught TypeError: Cannot read property 'uid' of
undefinedut.ui.DataBoundWidget.extend.cancelRow #

And finally a jsfiddle link to show what I'm doing. (The popup is empty because I just want to fix the open / close mechanism before going any further)
I don't understand why I get this error, I expected to be able to open / close the popup as many time as I wanted. The default editor popup is working fine.

One of my colleague found the solution (thanks to him).
Actually this piece of code
editable: {
mode: "popup",
window: {
animation: false,
open: openCustomWindow,
}
}
is designed to configure the default popup...
The right way to use a custom popup is the following :
editable :true,
edit: openCustomWindow,
With this approach it's also better to use
function editorWindowClosed(e) {
myGrid.cancelChanges();
}
Instead of
function editorWindowClosed(e) {
myGrid.cancelRow();
}
Working jsfiddle link

Actually the approach in my previous answer solved my issue but is causing another issue. The grid becomes editable but in the default mode (which is "inline").
Doing this
editable: "popup",
edit: openCustomWindow
has fixed this other issue but is now displaying 2 popups.
I finally succeeded to hide the default popup and only show my custom popup but it ended with the orginal issue described in initial question...
Considering all those informations I arrived to the conclusion that working with a custom popup window is definitely not an option. I'll start working with teamplates instead.
Another solution would have been to use a template to override the toolbar with a custom "Add" button and use a custom command for edition. But at this point I consider that too "tricky".

To prevent Kendo UI custom grid popup editor window, define the editable property:
editable:
{
mode: "popup",
window: {
animation: false,
open: updateRowEventHandler
}
} // skip edit property
Then paste preventDefault() at the beginning of the handler:
function updateRowEventHandler(e) {
e.preventDefault(); //

Re-rendering .ascx page with extjs

I need to dynamically add a column to a page that has already been loaded. The column is represented by an object that is created AFTER the .ascx page is loaded (via user interaction). On the JavaScript side of things, I have a Panel with a TabPanel:
var reportPanel = new Ext.Panel({
layout: 'fit',
items: [
new Ext.TabPanel({
id: 'reportTabs',
renderTo: 'reportTabContainer',
activeTab: 0,
autoHeight: true,
minHeight: 600,
plain: true,
stateful: true,
deferredRender: false,//allows both reports to run at once
defaults:
{
autoHeight: true
},
items: tabsConfig
})
]
});
};
an item in tabsConfig looks like this:
{{ id: 'totalOperation', title: 'Total Operation', autoLoad: {{url: '" +Url.Action("Detail","OverallReport") +"', params: 'null', scripts: true, timeout: '9000000', method: 'POST'}}
My problem is that once the column object has been created, I need to re-render the ascx page (aka the extJSpanel) after a specific AJAX call. I have tried panel.removeAll(true) as well as panel.doLayout(false,true), and that does not remove any of the elements in the panel, or refresh the page.
In short--I need to destroy an .ascx page before an AJAX call to the controller, and let the return of the AJAX call re-populate the ascx control (using return PartialView(...) ).
Any suggestions would be greatly appreciated.

Answered my question-this little snippet of code solved it:
var contentPanel = Ext.getCmp('totalOperation');
contentPanel.autoLoad = {
url: 'URL path of controller method'
};
contentPanel.doAutoLoad();

How to remove checkall option in extjs checkboxmodel?

How to remove check all option is extjs 4 checkboxmodel?
Regards

When defining a grid (in 4.2.1), set this config option to:
selModel: Ext.create('Ext.selection.CheckboxModel', { showHeaderCheckbox: false }),
(The relevant part is showHeaderCheckbox :false)

I have managed to hide it using pure CSS:
Code:
.x-column-header-checkbox {display:none;}

When you're creating your checkboxmodel, try specifying injectCheckbox: false into its configuration. From the API:
Instructs the SelectionModel whether or not to inject the checkbox header automatically or not. (Note: By not placing the checkbox in manually, the grid view will need to be rendered 2x on initial render.) Supported values are a Number index, false and the strings 'first' and 'last'.

Inside grid panel afterrender event using jquery
listeners: {
afterrender: function (grid) {
$('.x-column-header-checkbox').css('display','none');
}
}

According to API, the type of "header" property is String. Said that, the correct value is ''. It has worked for me on ExtJS 3.4
this.queueSelModel = new Ext.grid.CheckboxSelectionModel({
singleSelect : true, // or false, how you like
header : ''
});

heder:false in config or injectCheckBoxHeader = false hide the entire column. CSS solution is class based so any other widget using the same selection model would also hide the entire check.

In ExtJS 4 a header config can be provided as below to display a blank or custom text in the header.
getHeaderConfig: function() {
var me = this;
showCheck = false;
return {
isCheckerHd: showCheck,
text : ' ',
width: me.headerWidth,
sortable: false,
draggable: false,
resizable: false,
hideable: false,
menuDisabled: true,
dataIndex: '',
cls: showCheck ? Ext.baseCSSPrefix + 'column-header-checkbox ' : '',
renderer: Ext.Function.bind(me.renderer, me),
//me.renderEmpty : renders a blank header over a check box column
editRenderer: me.editRenderer || me.renderEmpty,
locked: me.hasLockedHeader()
};
},

I encountered this issue in ExtJS 4.0.7 version.
First I removed checkbox layout:
.rn-grid-without-selectall .x-column-header-checkbox .x-column-header-text
{
display: none !important;
}
Then I used the following code in afterrender listener of the grid:
afterrender: function (grid) {
this.columns[0].isCheckerHd = false;
}
It is not a good solution but it can be used as a starting point.

Thanks for all the good hints here.
For Sencha 3.4, this is the extremely simple pure CSS I ended up using,
My_Panel_With_a_Grid_Without_Header_CheckBox = Ext.extend(Ext.Panel, {....
cls: 'innerpanel hiddeGridCheckBoxOnSingleSelect',
....}
in my CCS file:
.hiddeGridCheckBoxOnSingleSelect .x-grid3-hd-checker {
visibility:hidden
}

Define {Header: false} in checkboxselectionModel
this.queueSelModel = new Ext.grid.CheckboxSelectionModel({
singleSelect : false,
header : false
});

Disappearing TabPanel card on setActiveItem?

EDIT
I have a viewport that extends a TabPanel. In it, I set one of the tabBar buttons to load another TabPanel called subTabPanel. myApp.views.viewport.setActiveItem(index, options) works just fine. But myApp.views.subTabPanel.setActiveItem(index, options) only loads the appropriate panel card for a split second before it vanishes.
Strangely, it works just fine to make this call from within the subTabPanel's list item:
this.ownerCt.setActiveItem(index, options)
However, I want to avoid this, as I want such actions to live inside controllers so as to adhere to MVC.
Any thoughts on why the card disappears when called from the controller, but not when called from the containing subTabPanel?
(The subTabPanel card in question is an extension of Ext.Carousel.)
UPDATE
It looks like both subTabPanel and its carousel are being instantiated twice somehow, so that could be a big part of the problem...

The answer in this case was to prevent the duplicate creation of the subTabPanel and its carousel.
The viewport now looks like this:
myApp.views.Viewport = Ext.extend(Ext.TabPanel, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'slide',
listeners: {
beforecardswitch: function(cnt, newCard, oldCard, index, animated) {
//alert('switching cards...');
}
},
tabBar: {
ui: 'blue',
dock: 'bottom',
layout: { pack: 'center' }
},
items: [],
initComponent: function() {
//put instances of cards into myApp.views namespace
Ext.apply(myApp.views, {
subTabPanel: new myApp.views.SubTabPanel(),
tab2: new myApp.views.Tab2(),
tab3: new myApp.views.Tab3(),
});
//put instances of cards into viewport
Ext.apply(this, {
items: [
myApp.views.productList,
myApp.views.tab2,
myApp.views.tab3
]
});
myApp.views.Viewport.superclass.initComponent.apply(this, arguments);
}
});
And I've since removed the duplicate creation of those TabPanel items from the items: property and moved their tabBar-specific properties into the view classes SubTabPanel, Tab2 and Tab3 (each of which are extensions of either Ext.TabPanel or Ext.Panel).

DataView hides spawning ComboBox

I posted this at the Ext forums a couple of days ago, but no response, so maybe better luck here.
I currently have a combo box loading data from php through ajax. Everything works fine except that when my results are returned, the DataView covers the ComboBox (fig 2.) I have included the relevant code below, so any help would be greatly appreciated.
I may be wrong, but I think I've eliminated CSS problems, as the DataView element is rendered with an absolute position.

Hard to say. The first thing I would do is rip the combo box out of your layout and try rendering it to a plain page and see if you still have this issue (should be simple to do). That will immediately confirm or rule out that it's related to your particular layout. You also did not mention whether or not this happens only in particular browser/OS combinations -- if so, it could be an Ext bug. If it happens in any browser, then it's probably an issue with your layout. Try narrowing it down first then maybe it will be more obvious where to go next.

It looks almost like the listAlign or hideParent are set wrong.. I'm not seeing that in your definition, but would double-check... try setting those to configuration options manually. I've also had issues with IE when not setting the listWidth config property.
