I am using ExtJs 3.3.1.
Within an EditorGrid, my "editable" column has a ComboBox as its editor. How can I have the ComboBox always showing for each row? Meaning, the user would not have to click on a cell to know there is a ComboBox there. Currently, I have clicksToEdit set to 1, but I wish I could set this to 0 (I tried that).
See some of my code below to see my current configuration.
var combo = new Ext.form.ComboBox({
typeAhead: true,
triggerAction: 'all',
lazyRender: true,
mode: 'local',
store: new Ext.data.ArrayStore({
id: 0,
fields: [
'statusId',
'displayText'],
data: data
}),
valueField: 'statusId',
displayField: 'displayText'
});
var cm = new Ext.grid.ColumnModel({
columns: [{
id: 'orderId',
header: 'ID',
dataIndex: 'id',
width: 50
}, {
header: 'Status',
dataIndex: 'status',
width: 130,
editor: (data.length == 1) ? null : combo,
renderer: Ext.util.Format.comboRenderer(combo)
}, {
id: 'orderSummary',
header: 'Summary',
dataIndex: 'summary',
renderer: this.renderSummary
}]
});
var orderGrid = new Ext.grid.EditorGridPanel({
store: this.getOrderStore(),
cm: cm,
autoExpandColumn: 'orderSummary',
clicksToEdit: 1
});
Here is the solution I came up with.
In my column model, I made sure that the column I am making "editable" has an id. Each cell in that column will now have a CSS class associated with it named "x-grid-col-{id}". My column id is "status" so the class was "x-grid-col-status".
I created the CSS for class "x-grid-col-status" which sets the dropdown arrow image as the background, aligned right. It also sets the cursor to pointer, so the user knows they can click on the cell.
.x-grid3-col-status
{
background-image: url(Image/trigger-single.gif);
background-position: right;
background-repeat: no-repeat;
cursor: pointer;
}
Next, I set up a listener for my ComboBox that listens for the 'focus' event. On focus, I expand the drop down. It is important that I had to add lazyInit: false to my ComboBox config, or else an empty list will appear when you expand. lazyInit - true to not initialize the list for this combo until the field is focused (defaults to true)
The code:
Ext.util.Format.comboRenderer = function (combo) {
return function (value, metaData, record, rowIndex, colIndex, store) {
var record = combo.findRecord(combo.valueField, value);
return record ? record.get(combo.displayField) : combo.valueNotFoundText;
}
}
var combo = new Ext.form.ComboBox({
typeAhead: true,
triggerAction: 'all',
lazyInit: false,
lazyRender: true,
mode: 'local',
editable: false,
store: new Ext.data.ArrayStore({
id: 0,
fields: [
'statusId',
'displayText'
],
data: data
}),
valueField: 'statusId',
displayField: 'displayText',
listeners: {
'focus': {
fn: function (comboField) {
comboField.doQuery(comboField.allQuery, true);
comboField.expand();
}
, scope: this
}
, 'select': {
fn: function (comboField, record, index) {
comboField.fireEvent('blur');
}
, scope: this
}
}
});
var cm = new Ext.grid.ColumnModel({
defaults: {
sortable: true
},
columns: [
{
id: 'orderId',
header: 'ID',
dataIndex: 'id',
width: 50
}, {
header: 'Status',
id: 'status',
dataIndex: 'status',
width: comboColumnWidth,
editor: combo,
renderer: Ext.util.Format.comboRenderer(combo)
}, {
id: 'orderSummary',
header: 'Summary',
dataIndex: 'summary',
renderer: this.renderSummary
}
]
});
var orderGrid = new Ext.grid.EditorGridPanel({
store: this.getOrderStore(),
cm: cm,
autoExpandColumn: 'orderSummary',
title: title,
clicksToEdit: 1
});
