Modern toolkit extjs: Context menu for empty grid - extjs

In modern toolkit extjs, how to create context menu for an empty grid(grid with no rows).

Add contextmenu listener to grid element:
Ext.application({
name: 'Fiddle',
launch: function () {
const store = new Ext.data.Store({
fields: ['name', 'email', 'phone'],
data: []
})
const menu = new Ext.menu.Menu({
items: [{
text: 'Menu Item 01'
}, {
text: 'Menu Item 02'
}]
});
Ext.Viewport.add({
xclass: 'Ext.grid.Grid',
store: store,
title: "My Empty Grid",
columns: [{
text: 'Name',
dataIndex: 'name',
width: 200
}, {
text: 'Email',
dataIndex: 'email',
width: 250
}, {
text: 'Phone',
dataIndex: 'phone',
width: 120
}],
height: 500,
listeners: {
initialize: function (grid) {
grid.element.dom.addEventListener("contextmenu", function (event) {
menu.showAt(event.pageX, event.pageY);
event.stopImmediatePropagation();
if (event.preventDefault != undefined) {
event.preventDefault();
}
if (event.stopPropagation != undefined) {
event.stopPropagation();
}
return false;
});
}
}
})
}
})

The best solution I've found is to add a context menu to the grid header. Trap the headercontextmenu event to do this.

ExtJS 7 How to select grid row on rightclick

I'd like to both open a context menu and select the right-clicked row in a ExtJS 7 modern grid. The context menu works with the code below. However, I cannot find a way to select the row. The grid.getSelectionModel() seems to be no longer available in ExtJS 7.
// Listener in my Ext.app.ViewController manages to update and show context menu but not to select the row.
onContextMenu: function (e) {
const grid = this.getView();
const target = e.getTarget(grid.itemSelector);
if (target) {
e.stopEvent();
const item = Ext.getCmp(target.id);
if (item) {
// Would like to select row here with something like grid.getSelectionModel().selectRow(rowindex);
this.updateMenu(item.getRecord(), item.el, e);
}
}
}
Have a look at the following fiddle sample (Modern toolkit 7.3.1)
Ext.application({
name: 'Fiddle',
launch: function () {
const menu = new Ext.menu.Menu({
items: [{
text: 'Menu Item 1'
}, {
text: 'Menu Item 2'
}]
});
Ext.Viewport.add({
xclass: 'Ext.grid.Grid',
store: Ext.create('Ext.data.Store', {
fields: ['name', 'email', 'phone'],
data: [{
name: 'Lisa',
email: 'lisa#simpsons.com',
phone: '555-111-1224'
}, {
name: 'Bart',
email: 'bart#simpsons.com',
phone: '555-222-1234'
}]
}),
columns: [{
text: 'Name',
dataIndex: 'name',
width: 200
}, {
text: 'Email',
dataIndex: 'email',
width: 250
}, {
text: 'Phone',
dataIndex: 'phone',
width: 120
}],
listeners: {
childcontextmenu: function (grid, location) {
const {
record,
event
} = location;
grid.deselectAll();
grid.setSelection(record);
menu.showAt(event.getX(), event.getY());
event.stopEvent()
}
}
})
}
});

ExtJS: Issue with scope in class

I'm keep facing with a issue to choice exact component with scope. As you'll notice below I've created 2 different functions inside gridpanel. One of those creates a Ext.MessageBox for confirm. And other function creates a Ext.window.Window depends on button click of MessageBox.
The thing here is; It should destroy related component with cancel and no buttons. Both buttons always point to gridpanel because of var me = this state and destroys the gridpanel itself.
How can I point destroy method directly to related component?
Ext.define('MyApp.FooGrid', {
extend: 'Ext.grid.Panel',
reference: 'fooGrid',
getGridMenu: function () {
// Here is the 'Update' function; with right-click user being able to see `contextmenu`
var me = this;
var ret = [
{
text: 'Update',
listeners: {
click: me.onUpdate,
scope: me
}
}
];
return me.callParent().concat(ret);
},
onUpdate: function () {
var me = this,
gridRec = this.getSelectionModel().getSelection(); // Here being able to retrieve row data.
Ext.MessageBox.confirm(translations.confirm, translations.confirmChange, me.change, me);
return gridRec;
},
change: function (button) {
var me = this;
var selectedRec = me.onUpdate();
var selectedRecEmail = selectedRec[0].data.email; //Retrieves selected record's email with right-click action
if (button === "yes") {
return new Ext.window.Window({
alias: 'updateWin',
autoShow: true,
title: translations.update,
modal: true,
width: 350,
height: 200,
items: [
{
xtype: 'container',
height: 10
},
{
xtype: 'textfield',
width: 300,
readOnly: true,
value: selectedRecEmail //Display selected record email
},
{
xtype: 'textfield',
width: 300,
fieldLabel: translations.newPassword
}
],
dockedItems: [
{
xtype: 'toolbar',
dock: 'bottom',
items: [
{
xtype: 'tbfill'
},
{
xtype: 'button',
text: translations.cancel,
listeners: {
click: function () {
me.destroy(); // Here is the bug: When user clicks on this button; should destroy current window but it destroys 'gridpanel' itself
}
}
},
{
xtype: 'button',
text: translations.save,
listeners: {
click: function () {
console.log("I'll save you!");
}
}
}
]
}
]
});
} else {
console.log('this is no!');
me.destroy(); // Another bug raises through here: If user will click on No then 'messagebox' should destroy. This one is destroys the gridpanel as well.
}
}
});
How can I point destroy method directly to related component?
Firstly on confirmation box button's(No) click, you don't need to destroy it will automatically hide the box whenever you click into No.
And for update window instead of using me.destroy() you need to use directly button.up('window').destroy() so it will only destroy your update window not the grid.
And also you don't need to again call me.onUpdate() inside of change function otherwise it will again show the confirmation box. You can directly get selected record on the change function like this me.getSelection().
In this Fiddle, I have created a demo using your code and I have put my efforts to get result.

Form with textfield and grid: send all values to the server

In create and update forms, it is sometimes necessary to give the user the ability to dynamically add fields to values of the same type (more than one phone, more than one address, etc.).
I'm exploring several possibilities to do this.
One of them is to use a grid as a form field.
However, I have doubts about how best to implement this idea, especially on how to send all the form field values (textfield and grid) to the server (and then how to load them later in the form to edit).
Fiddles with some ideas:
One with cellediting plugin https://fiddle.sencha.com/#view/editor&fiddle/2ftp
Another one with roweditin gplugin a https://fiddle.sencha.com/#view/editor&fiddle/2fto
Not sure about the "best to implement", but I have seen so many requirements for multivalue input, that for reusability I have in my toolbox a gridfield similar to the following one:
Ext.define('Ext.ux.GridField', {
extend: 'Ext.form.FieldContainer',
alias: 'widget.gridfield',
initComponent: function () {
var me = this;
if(!me.columns) me.columns = {
dataIndex: 'field1'
};
if(!me.mapFn) me.mapFn = function(value) {
if(Ext.isObject(value)) return value;
return {
field1: value
};
};
if(!me.unmapFn) me.unmapFn = function(record) {
return record.get('field1');
};
me.grid = Ext.widget(Ext.apply({
xtype: 'grid',
viewConfig: {
markDirty: false
},
store: me.store || Ext.create('Ext.data.Store', {
fields: me.columns.map(function(column) {
return {
name: column.dataIndex,
type: column.dataType || 'auto',
defaultValue: column.defaultValue
};
}),
listeners: {
update: me.updateValue,
datachanged: me.updateValue,
scope: me
}
}),
columns: [{
xtype: 'actioncolumn',
getClass: function () {
return 'x-fa fa-times'
},
handler: function(grid, rowIndex, colIndex, item, e, record) {
grid.getStore().remove(record);
},
width: 35
}].concat(me.columns),
bbar: [{
xtype: 'button',
iconCls: 'x-fa fa-pencil',
text: 'Add',
handler: function(btn) {
var grid = btn.up('grid'),
store = grid.getStore(),
record = store.add(Ext.clone(me.emptyRecord) || {})[0];
grid.getPlugin('editor').startEditByPosition({
row: store.indexOf(record),
column: 1
});
}
}],
plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
pluginId: 'editor',
clicksToEdit: 1
})
]
}, me.gridConfig)); // "gridConfig" config can override everything on each instance.
me.hiddenField = Ext.widget({
xtype: 'hiddenfield',
name: me.name,
value: '',
allowNull: false,
rawToValue: function (raw) {
return raw;
},
valueToRaw: function (value) {
return value;
},
getRawValue: function () {
return Ext.valueFrom(this.rawValue, '')
},
isEqual: function (a, b) {
return Ext.encode(a) == Ext.encode(b)
},
listeners: {
change: function(field, nV, oV) {
if(!Ext.isArray(nV)) nV = [nV];
var store = me.grid.getStore();
store.removeAll();
store.add(nV.map(me.mapFn));
}
}
});
Ext.apply(me, {
layout: 'fit',
items: [{
xtype:'container',
border: 1,
style: {
borderColor: '#d0d0d0',
borderStyle: 'solid'
},
items: [me.grid]
}, me.hiddenField]
});
me.callParent(arguments);
},
updateValue: function() {
var me = this,
grid = me.grid,
hiddenField = me.hiddenField,
nV = grid.getStore().getRange().map(me.unmapFn, me),
oV = me.hiddenField.getValue();
if(!oV || Ext.isArray(oV) && Ext.encode(nV) != Ext.encode(oV)) {
hiddenField.suspendCheckChange++;
hiddenField.setValue(nV);
hiddenField.suspendCheckChange--;
me.fireEvent('change', me, nV, oV);
}
}
});
which can then be used like this:
},{
xtype: 'gridfield',
fieldLabel: 'Contacts',
name: 'contacts',
columns: [{
text: 'Type',
dataIndex: 'type',
editor:{
xtype: 'combobox',
name: 'type',
valueField: 'name',
displayField: 'name',
store: combostore,
queryMode: 'local'
},
flex: 0.7
},{
text: 'Description',
dataIndex: 'description',
editor:{
xtype: 'textfield',
name: 'description'
},
flex: 1
}],
mapFn: function(value) {
return value;
},
unmapFn: function(record) {
return record.getData();
}
}, {
I have made a fiddle for you based on your fiddle, including working load and save operations on the form, but in ExtJS 6.x. And I have checked that it works with ExtJS 5 as well, although you have to add working icons.

extjs6 modern card layut

I am new in Extjs. I have a container with card layout with 3 sub views including a grid, a form for creating and a form for updating using route.
items: [
{xtype: 'feature-grid',id:'feature-grid},
{xtype: 'create-form'},
{xtype: 'update-form'}
],
it works well at the first time but when I change the route and switch to this route again this error appears:
Uncaught Error: DOM element with id feature-grid in Element cache is not the same as element in the DOM. Make sure to clean up Element instances using destroy()
and when I remove the id the save button in my create form doesnt add record to the grid without any error!
my save button is like this:
var form = button.up('formpanel');
var values = form.getValues();
var user = Ext.create('App.model.User',values);
var cntr = this.getView('UserContainer')
var mainpanel = button.up('user-container');
var grid = mainpanel.down('grid');
grid.store.add(user);
form.reset();
this.redirectTo('users')
any idea?
As you are using routes so in this case first you need to check you view is already created or not. If view is already created then you can use that view otherwise you can create view.
In this FIDDLE, I have create a demo using cardlayout, grid and form. I hope this will help/guide you to achieve your requirement.

How to create a Form for each row in a grid panel:extjs

How do i create a different form for each row in the Grid...
i have a grid like ..
Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
store: Ext.data.StoreManager.lookup('simpsonsStore'),
columns: [
{ text: 'Name', dataIndex: 'name' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone' }
],
height: 200,
width: 400,
renderTo: Ext.getBody()
});
Your question doesn't explain your problem very well. Please update your topic and question. As I understood from your question, yes, you can. There are couple of ways. One of them is putting a form into a grid cell using grid column renderer. Another way is using editor in grid column. The second way is easy, but it's not proper way. If you want the second way also, I can add it. So, I'll add an efficient one. Please check the code below and fiddle:
https://fiddle.sencha.com/#fiddle/11i5

var form = this.up('form').getForm();
if(form.isValid()){
form.submit({
