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()
})

ExtJS4 - Outline appearing around Submit button for form

I have a fileuploadfield button that has an outline of a white box appearing behind it. Is there a way to remove this?
It seems to only be an issue in Extjs4.
Code
items: [{
xtype: 'form',
name: 'upload_form',
border: false,
items: {
text: 'File Upload',
xtype: 'fileuploadfield',
name: 'upload_btn',
buttonText: 'Upload File...',
buttonOnly: true,
hideLabel: true,
allowBlank: false,
clearOnSubmit: false,
}
}]
Fiddle

Since you must have the fileuploadfield inside a form, my workaround was to use a bodyStyle configuration in the form, set the background-color to transparent, and a margin-top to re-center the fileuploadfield.

ExtJS remove text and add items into header after the panel collapsed

I use Ext5 and I have a question. Is it possible to remove text and add items into panel header after the panel collapsed?
Belows the code, the east panel is collapsible. I want to remove text and add items into header after it collapsed.
Ext.create('Ext.container.Viewport', {
layout: 'border',
items: [{
region: 'east',
title: 'East Panel',
collapsible: true,
split: true,
width: 150
}, {
region: 'center',
xtype: 'tabpanel', // TabPanel itself has no title
activeTab: 0, // First tab active by default
items: {
title: 'Default Tab',
html: 'The first tab\'s content. Others may be added dynamically'
}
}]
});
UPDATE
In this case, I add buttons into header but when the panel is collapsed the button disappeared. Is there any way to show or add components into header when panel is collapsed?
{
region: 'east',
title: 'East Panel',
collapsible: true,
split: true,
width: 150,
header: {
items: [{
xtype: 'button'
}, {
xtype: 'button'
}]
}
}
here is the fiddle
Thanks

Please refer to "placeholder" related configs in Ext.panel.Panel class. Below is your code from fiddle modified.
Ext.create('Ext.container.Viewport', {
layout: 'border',
items: [{
region: 'east',
title: 'East Panel',
collapsible: true,
collapseMode:'placeholder',// set collapseMode to placeholder
split: true,
width: 300,
placeholder:{ // Try different components and layout configs
width:100,
items:[{
xtype:'button',
text:'Button 1'
}]
}
/*header: {
items: [{
xtype: 'button'
}, {
xtype: 'button'
}]
}*/
}, {
region: 'center',
xtype: 'tabpanel', // TabPanel itself has no title
activeTab: 0, // First tab active by default
items: {
title: 'Default Tab',
html: 'The first tab\'s content. Others may be added dynamically'
}
}]
});

The header you see collapsed is actually another instance of Ext.panel.Header created just for this purpose. I tried to find some configs to customize it, but the Ext.panel.Panel was not created having it in mind.
So you'll have to override the method which creates this reader, which I found out is called createReExpander. It's a big method hard to override without having to rewrite a lot of stuff, but it can be done.
I tried adding buttons to the header and the result was not visually nice, but at least they were created!
So I would suggest you use tools instead of buttons if you don't need text on them.

How to dynamically make a combobox multiselect/singleselect in extjs

I am using Boxselect extended from combo box in ExtJs 4.1. Based on some condition i need to make the selection single or multi.
here is my code
bool result;
result = getData();
if(result)
{
Ext.getCmp("combo1").multiSelect =true
}
This does not change the combobox to multiselect .any ideas ?

You have to force the recreation of the picker when the multiSelect option change. For that, you need to delete the property picker of your combo:
combo.multiSelect = true;
delete combo.picker;
Complete example:
Ext.widget('panel', {
renderTo: Ext.getBody(),
layout: {type: 'vbox', align: 'center'},
margin: 10,
defaults: {width: 200, margin: 5},
items: [{
xtype: 'combo',
store: ['Foo', 'Bar', 'Baz']
},{
xtype: 'displayfield',
fieldLabel: 'Multiselect is',
value: "OFF"
},{
xtype: 'button',
text: "Toggle multiselect",
handler: function() {
var panel = this.up(),
combo = panel.down('combo'),
outField = panel.down('displayfield'),
newValue = !combo.multiSelect;
combo.multiSelect = newValue;
// force recreation of picker
delete combo.picker;
outField.setValue(newValue ? "ON" : "OFF");
}
}]
});

Try with the Ext.apply method.
combo = Ext.getCmp.....
Ext.apply(combo, {multiSelect: true});

Ext.form.Panel on top of a Toolbar has some white space around it

I have the following situation. I have an Ext.form.field.File (With the buttonOnly: true on top of a Ext.form.Panel which is on top of a Toolbar docked on an Ext.grid.Panel. The result of that is, the button has a completely different style then the toolbar, and the Panel seems to have some white space around button that you can see. Anyone have any suggestions as to how I can fix this, so that the style of the button and panel matches the toolbar (I use default styles, didn't modify anything).
EDIT: here is some code:
upload_button = Ext.create('Ext.form.field.File', {
buttonOnly: true,
buttonText: "Upload File",
hideLabel: true,
listeners: {..}
});
button_panel = Ext.create('Ext.form.Panel', {
region: 'south',
items: upload_button
});
upload_toolbar = Ext.create('Ext.toolbar.Toolbar',{
width: 400,
region: 'north',
dock: 'top',
items: [ button_panel]});
grid_file = Ext.create('Ext.grid.Panel', {
title: 'File List',
region: 'center',
height: 300,
store: store_file,
dockedItems: [upload_toolbar],

You are using regions, but I cannot see any border layout.
Your problem is that you are trying to put a panel within a toolbar - it won't work.
You better off just putting an hidden upload form somewhere in your page; putting a normal button in the toolbar, and have the toolbar button press triggering a press on the hidden form.
So this would be the hidden upload form definition:
Ext.define('App.view.Assignments' ,
{
extend: 'Ext.panel.Panel',
alias: 'widget.assignments-panel',
hidden: true,
items: [{
xtype: 'filefield',
id: 'uploadField',
emptyText: 'Select a file',
fieldLabel: 'Assignment',
name: 'assignment-path',
buttonText: '...',
buttonConfig: {
iconCls: 'upload-icon'
}
},{
xtype: 'hidden',
id: 'submissionIdField',
name: 'submissionId',
value: ''
}],
});
And then when the visible update button is pressed you can do:
var uploadField = Ext.getCmp( 'uploadField' );
uploadField.fileInputEl.dom.click();
