Custom Grid Cell Editor

[harman]

Hi All,

I am defining an ExtJS 4.0.7 component to use it as an editor for a grid cell as follows



Ext.define('My.pickerField',{
extend:'Ext.form.field.Picker',
alias: ['widget.customPicker'],
width:155,
editable:false,
value: gridStore.getAt(rowIndex).get('somefield'),
createPicker: function() {
return Ext.create('Ext.panel.Panel', {
//....
//....
});
}
});

//Column where editor is placed
{
text: "Header",
dataIndex: 'field1',
width:158,
align : 'center',
sortable: true,
editor: {
xtype: 'customPicker'
}
}




Now the problem is to pass the grid store and row index to the xtype.
How can i do that?

May be i am doing it with wrong approach.
If so how do i use a custom editor ?

Thanks in advance.

You should not need to .. it is already part of a form that is updated.

See the following:



Ext.onReady(function(){

Ext.define('MyPickerField',{
extend:'Ext.form.field.Picker',
alias: 'widget.customPicker',
editable:false
});

var store = Ext.create('Ext.data.Store', {
storeId:'simpsonsStore',
fields:['name', 'email', 'change'],
data:{'items':[
{ 'name': 'Lisa', "email":"lisa@simpsons.com", "change":100 },
{ 'name': 'Bart', "email":"bart@simpsons.com", "change":-20 },
{ 'name': 'Homer', "email":"home@simpsons.com", "change":23 },
{ 'name': 'Marge', "email":"marge@simpsons.com", "change":-11 }
]},
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'
}
}
});

var editor = {
xtype: 'textfield',
allowBlank: false
};

var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
clicksToMoveEditor: 1,
autoCancel: false
});

Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
store: store,
columns: [
{ header: 'Name', dataIndex: 'name', editor: { xtype: 'customPicker' } },
{ header: 'Email', dataIndex: 'email', flex: 1, editor: editor },
{ header: 'Change', dataIndex: 'change', editor: editor }
],
height: 200,
width: 400,
renderTo: Ext.getBody(),

plugins: [rowEditing]
});

});

Hi Scott,

Thanks for pointing in the right way to implement editor. But i have a few things
Firstly, I am using a cell editor as its view suits more to my requirements.
so i use Cell Editing plugin instead but that is not a prob.
secondly i am making a tree panel when the createPicker function executes.
something like

createPicker: function() { return Ext.create('Ext.tree.Panel', {
//....
//....
});
}
Inside tree i need the rowIndex for some operations.
How can i get rowIndex in picker so i can pass it on to inner tree?
