Change Extjs Grid Validation Text

I'm looking at an older project that is using ExtJS. Admittedly, I'm not too familiar with this framework so I learn as I go and as I am asked to fix things. My issue is that there is a grid and each column uses allowBlank: false. This causes a tooltip box to display with some info about what field(s) need to be populated. This all works great, but I am trying to change that text in that tooltip i.e. "Error", "Benefit Category Name: This field is required", and I can't seem to make this work. How can I target and change that text? I'll include a screenshot of the grid and tooptip that I am talking about for reference. I am also using ExtJS version 6.
Here is a sample of one of the grid columns:
columns: [
{
dataIndex: 'benefit_category_name',
text: 'Benefit Category Name',
flex: 1,
editor: {
xtype: 'combo',
store: new Ext.data.ArrayStore({
fields: [
'benefit_category_id',
'benefit_category_name',
],
data: [],
}),
queryMode: 'local',
valueField: 'benefit_category_name',
displayField: 'benefit_category_name',
emptyText: 'Select one',
listeners: {
select: 'handleComboChange',
},
itemId: 'benefit_category_id',
allowBlank: false,
listeners: {
renderer: function(value, metaData) {
metaData.tdAttr = Ext.String.format('data-qtip="{0}"', value);
return value;
}
}
}
},
{
...
}
]
I tried to use the metaData property I read about in some other posts, but I can't seem to change the tooptip text (Error, Benefit Category Name: This field is required).
Here is a screenshot of the tooltip mentioned. I know this is an older framework, but any tips I could get would be useful. Thanks for your time.

Thats a simple validation example with custom message.
Ext.create({
xtype: 'textfield',
allowBlank:false, // will show required message - remove key to display vtypeText only
validateBlank: true,
vtype: 'alpha', // check for available types or create / extend one
vtypeText: 'Please change to what you want ...',
renderTo: Ext.getBody()
})

Problems with references and stores in Sencha ExtJS

I’m new here in at Stackoverflow and to Sencha ExtJS development. I’m a student from Germany and I’m current trying to get my degree in media computer sciences. As a part of my final assignment I’m currently developing the UI of a webapp for a local company.
While I was trying out the capabilities of the Sencha ExtJS framework I came across some problems, which is why I’m now reaching out to the community for help ;)
My first problem I had, was when I was playing around with the syntax for instancing classes using xtypes and the association of Stores inside the ViewModel:
For the purpose of easier to read and less cluttered code I wanted to give my stores their own xtype so I could instead of declaring all the stores and their configs inside the ViewModels’ stores config wanted to have every store inside their own file and then just create an instance of them later inside the ViewModel. The code I wrote for this looks like this:
ViewModel:
Ext.define('Example.viewmodel.MyViewModel', {
extend: 'Ext.app.ViewModel',
alias: 'viewmodel.myviewmodel',
requires: [
'Example.store.MyStore',
],
stores: {
StoreA: { xtype: 'store_a' },
StoreB: { xtype: 'store_b' },
StoreC: { xtype: 'store_c' }
},
data: {
/* This object holds the arbitrary data that populates the ViewModel and
is then available for binding. */
}
});
StoreA:
Ext.define('Example.store.StoreA', {
extend: 'Ext.data.Store',
xtype: 'store_a',
requires: [
'Example.model.ModelA'
],
storeId: 'StoreA',
autoLoad: false,
model: 'Example.model.ModelA',
listeners: {
load: 'onLoadofStoreA'
}
});
But apparently this isn’t working… My load listener of the store does not seem to fire at the method inside my controller and does not even seem to know about the view that is associated with the ViewModel. What am I doing wrong or is this just not meant to be done like that?
My Second Problem was when I was playing around with some of the UI components. My scenario was like this:
I wanted to have a menu that would slide in, where u could do some inputs that would then load the content for the view.
I found this example for a sliding menu (https://examples.sencha.com/extjs/6.7.0/examples/kitchensink/?modern#menus) and built this:
Inside my ViewController:
getMenuCfg: function (side) {
var cfg = {
side: side,
controller: example_controller',
id: 'topMenu',
items: [
{
xtype: 'container',
layout: 'hbox',
width: '100%',
items: [
{
xtype: 'fieldset',
reference: 'fldSet',
id: 'fldSet',
layout: 'vbox',
width: '50%',
defaults: {
labelTextAlign: 'left'
},
items: [
{
autoSelect: false,
xtype: 'selectfield',
label: 'Selectfield',
reference: 'sfExample',
id: 'sfExample',
listeners: {
change: 'onSFChange'
}
},
{
xtype: 'container',
layout: {
type: 'hbox',
align: 'end',
pack: 'center'
},
items: [{
xtype: 'textfield',
reference: 'ressource',
id: 'ressource',
flex: 1,
textAlign: 'left',
margin: '0 10 0 0',
label: 'Ressource',
labelAlign: 'top',
labelTextAlign: 'left',
editable: false,
readOnly: true
},
{
xtype: 'button',
shadow: 'true',
ui: 'action round',
height: '50%',
iconCls: 'x-fa fa-arrow-right',
handler: 'openDialog'
}
]
},
{
xtype: 'textfield',
reference: 'tfExample',
id: 'tfExample',
label: 'Textfield',
editable: false,
readOnly: true
}
]
},
}]
}];
The problem I come across now is, that I would no longer be able to easily get the references of components inside the menu (input fields) with this.lookupReference() as if they were just part of the view. In fact to find a workaround I had to trace a way back to the components using a debugger.
For example if another method inside my controller wanted to use a field inside this menu, instead of simply just doing this.lookupReference(‘sfExample’) I now had to do something like this:
var me = this,
vm = me.getViewModel(),
menuItems = me.topMenu.getActiveItem().getItems(),
fieldset = menuItems.getByKey('fldSet'),
selectfieldRessArt = fieldsetLeft.getItems().getByKey('sfExample');
I’m pretty sure that I am missing out on something important here and there has to be a way to do this easier. I’m really looking forward to your answers, thank you in advance ;)

use xtype only for components. if you need to define an type/alias for store, use alias config property instead and especify the alias category "store.".
Defining a store with an alias
Ext.define('Example.store.StoreA', {
extend: 'Ext.data.Store',
//use store. to category as a store
alias: 'store.store_a',
requires: [
'Example.model.ModelA'
],
storeId: 'StoreA',
autoLoad: false,
model: 'Example.model.ModelA',
listeners: {
load: 'onLoadofStoreA'
}
});
Instantianting your store by type
Ext.define('Example.viewmodel.MyViewModel', {
extend: 'Ext.app.ViewModel',
alias: 'viewmodel.myviewmodel',
requires: [
'Example.store.MyStore',
],
stores: {
StoreA: { type: 'store_a' },
StoreB: { type: 'store_b' },
StoreC: { type: 'store_c' }
},
data: {
/* This object holds the arbitrary data that populates the ViewModel and
is then available for binding. */
}
});
I Hope it can help you

EXT JS 2.3; Internet Explorer 8; GridPanel Records Wrap, but Shouldn't

I'm using EXT JS 2.3 and looking at an issue that occurs with Internet Explorer 8. If you take a look at the company column in an example on this page, It is cutting off the lines that are too long such as E.I. du Pont de Nemours and Co... (just an example, not using a simple array grid; just a normal GridPanel)
That is the correct behavior I would like, which is what happens in Firefox, and later versions of Internet Explorer.
However, in Internet Explorer 8 the row is actually wrapping to take up two rows, with the last bit in the second row.
I looked in documentation for 2.3, but not finding any config options that seem to help. I tried setting autoHeight to false, but no effect. Most other questions I find are the reverse, where they want it to wrap but it doesn't.
How can I keep Internet Explorer 8 from wrapping?
Here is the javascript...
Column Model
var columnModel = new Ext.grid.ColumnModel([
{
dataIndex: 'Name',
id: 'fieldLabel',
width: parseInt(width)/4
},
{
dataIndex: 'Description',
id: 'fieldDataGrey',
width: parseInt(width)/4
}
]);
Grid Panel 1
var Grid1 = new Ext.grid.GridPanel({
id: 'Grid1',
name: 'Grid1',
store: DataStore1,
cm: columnModel,
width: parseInt(width)/2,
autoHeight: false,
collapsible: false,
frame: false,
stripeRows: false,
columnLines: true,
hideHeaders: true,
enableColumnHide: false,
disableSelection: true,
overCls: '',
loadMask: true
});
Grid Panel 2
var Grid2 = new Ext.grid.GridPanel({
id: 'Grid2',
name: 'Grid2',
store: DataStore2,
cm: columnModel,
width: parseInt(width)/2,
autoHeight: false,
collapsible: false,
frame: false,
stripeRows: false,
columnLines: true,
hideHeaders: true,
enableColumnHide: false,
disableSelection: true,
overCls: '',
loadMask: true
});
Field Set
var FieldSet = new Ext.form.FieldSet({
id: 'FieldSet',
name: 'FieldSet',
title: 'Title',
border: true,
width: width,
autoHeight: false,
labelWidth: 125,
bodyStyle: 'padding:2px; margin:0px',
style: 'padding:2px; margin:0px',
layout: 'tableform',
layoutConfig: {
columns: 2,
columnWidths:[.5, .5]
},
items: [
Grid1,
Grid2,
{
labelWidth: 125,
layout: 'form',
bodyStyle:'padding:2px 0px 0',
items: Label,//Didn't include label with posted code
colspan: 2
}
]
});

Try to use 2.2.1 ExtJs version, or 3.x. The problem I think lays in the Ext.js module in the Ext distribution, where browser versions are detected.

Ext.grid.ColumnModel has a config option called "renderer." I have used this function often for styling or DOM manipulation that Ext did not provide in the config options. You might try using the renderer function and returning an HTML string with custom styling that forces no wrapping on the data.
For instance,
renderer: function(value, metadata, record, rowIndex, colIndex, store) {
var style = 'overflow:hidden; white-space: nowrap; width: 100px;',
html = '<span style="' + style + '">' + value + '</span>';
return html;
}
Where "width" (100px in this case) is the width you defined in your column.

After further testing I did not find the solution I hoped for, but I did partially fix it by using a renderer rather than the fieldDataGrey id and using a column layout rather than the tableform layout.

ExtJS 4 Grid unwanted scrolling on load and node selection

I have a problem with the ExtJS 4 grid. I am using ExtJS 4.2.1, and whenever I load data into my grid using the loadRawData function, it automatically scrolls to the bottom, or near the bottom. Also, I am using grouping in the grid, and whenever I expand or collapse the node, it auto scrolls to the bottom again. This is really frustrating, and I can't seem to find a solution. I tried any solutions in this post from the Sencha forums, but nothing seemed to work.
This is my grid config:
gridPanel = new Ext.grid.Panel({
header: false,
title: 'Resultset',
id: 'resultTable',
width: 400,
split: true,
collapsible: true,
collapseMode: 'mini',
store: {
model: 'resultset',
autoLoad: false,
pageSize: 100,
proxy: {
type: 'ajax',
url: STORE_URL,
reader: {
type: 'json',
root: 'rows'
}
},
groupField:'tid'
},
features: [{ftype:'grouping'}],
deferRowRender: false,
columns: createColumns(),
selModel: {
checkOnly: true,
moveEditorOnEnter: false,
width: 20,
mode: 'MULTI'
},
selType: 'rowmodel',
tbar: [ createMenubar() ],
bbar:[ createPagingBar() ],
/*viewConfig: {
preserveScrollOnRefresh: true
}*/
});
And then when I load the data, I just do something like this:
var store = gridPanel.getStore();
store.loadRawData(data, false);
Any help would be appreciated!

How to make HTML render properly into ExtJS tabs?

I am developing a simple JavaScript-based plugin architecture which allows for any JavaScript control from any framework (jQueryUI, ExtJS, etc). to be plugged into and reused on any web page. My plugins below happen to use ExtJS 4.
The first plugin renders fine in the first tab. However, since the second tab hasn't yet rendered when the page loads, the second plugin (also a grid) is first rendering to the document body, and then it renders properly (the HTMLElement/div is moved) inside the tab when the tab is selected. I'd like the plugin content to be hidden prior to rendering inside the tab. Also, when it it does render [when the tab is selected], horizontal scrollbars don't show unless I resize a column.
Any ideas how to fix this?
Ideas: use something other than contentEl; leverage various ExtJS config options; change my architecture.
Here is the plugin code:
(function(MyNamespace) {
var gridDataStore = ...
MyNamespace.Plugin.Chart = MyNamespace.Plugin.extend({
return {
initialize: function() {
// ...
},
render: function() {
var stockGrid = Ext.create('Ext.grid.Panel', {
autoRender: true,
autoShow: true,
store: gridDataStore,
header: false,
stateId: 'stateGrid',
columns: [
{text: 'Symbol', width: 75, sortable: true, dataIndex: 'symbol'},
{text: 'Description', width: 200, sortable: true, dataIndex: 'description'},
{text: 'Quantity', width: 75, sortable: true, dataIndex: 'quantity'},
{text: 'Last Price', width: 85, sortable: true, dataIndex: 'last_price'}
],
viewConfig: {
stripeRows: true,
enableTextSelection: true
}
});
return stockGrid.getEl().dom;
}
};
}
})(MyNamespace);
And here's code using the plugin:
var chart = new MyNamespace.Plugin.Chart();
var anotherPlugin = new MyNamespace.Plugin.Another();
var stocksWindow = Ext.create('Ext.Window', {
title: 'Stocks',
width: 600,
height: 450,
layout: 'fit',
items: [
Ext.create('Ext.tab.Panel', {
activeTab: 0,
items: [{
title: 'Chart',
autoScroll: true,
contentEl: chartPlugin.render() // RENDER FIRST PLUGIN IN FIRST TAB
},{
title: 'Something Else',
autoScroll: true,
contentEl: anotherPlugin.render() // RENDER SECOND PLUGIN IN SECOND TAB
}]
})
]
});
I can add it to an invisible container, but it feels dirty doing so:
var container = document.createElement('div');
document.getElementsByTagName('body')[0].appendChild(container);
container.style.visibility = 'hidden';
var stockGrid = Ext.create('Ext.grid.Panel', {
...
renderTo: container
...
});
Here's an example

Here are a few problems with your code.
What you are calling plugins are not plugins, they are just subclasses of Ext.grid.Panel. A plugin is something that adds functionality to an Ext.Component, but that is not what Stocks is doing. It's just what we call a preconfigured class.
Here's what I would do, just make MyNamespace.Plugin.Stocks be a subclass of Ext.grid.Panel, you can now easily pass those as the items of a Ext.tab.Panel. Make sure you rename it, it's not a plugin.
By giving your widget subclasses the alias: 'widget.stock-grid', you can create them using just an object definition, without having to instantiate them, the framework will take care of rendering it only when needed (the tab is activated)
Ext.create('Ext.tab.Panel', {
activeTab: 0,
items: [{
title: 'Stocks',
autoScroll: true,
xtype: 'stock-grid'
},{
title: 'Orders',
autoScroll: true,
xtype: 'stock-grid'
}]
})
When using managed layouts, you cannot just simply copy a node into another container, because the node you copied in there won't have a managed layout.
Here's a modified version of your code that is written more like Ext-JS intended it. http://jsfiddle.net/NVfRH/10/
You can look into the generated HTML and you'll notice that the grid under orders only renders when you activate that tab.
You should also notice that your grids weren't properly sizing themselves to fill the window, my code fixes that since they are correctly placed in the layout pipeline and obey the fit layout.
Remaining Problems
Your grids are sharing a store, notice that when you sort one, the other gets sorted, so you can't have them with different sorting.
You were using a stateId, but then you were creating two instances with the same stateId, all stateIds must be unique
And lastly, I must ask, were you really relieved when Chad Johnson changed his name to Chad Ochocinco? :)
