Am having a problem with the following selectfield on my form:
{
xtype: 'selectfield',
label: 'Title',
displayField: 'ItemName',
valueField: 'Id',
listeners: {
initialize: function () {
var titleStore = Ext.create('MyApp.store.Titles', {});
this.setStore(titleStore);
}
}
},
On the form which uses the selectfield, whenever I select the option the form updates correctly, but the first item in the list always has a check mark against it. Also when selecting the first item in the list never updates the form. My knowledge of ST is limited but surely this should work out of the box?
Any ideas why this isn't working?
This was down to a silly error. The data coming from the server had identical 'Id' values, so when an item in the list was selected it had the same value as the rest of the items. The select field would then just show the first item that matched the 'Id' value which would be the first in the list.

I want to realize the functionality that we can search the users' name by typing in the first character of their names. I need to use Javascript to create a custom html.
Is there anyone who has done this before could help me?
In the example from this repository, a user combobox Rally.ui.combobox.UserComboBox searches for matching values dynamically based on the first couple of characters.
This default functionality displays the expected values after the second character is entered.
var u = Ext.create('Rally.ui.combobox.UserComboBox',{
id: 'u',
project: project,
fieldLabel: 'select user',
listeners:{
ready: function(combobox){
this._onUserSelected(combobox.getRecord());
},
select: function(combobox){
this._onUserSelected(combobox.getRecord());
},
scope: this
}
});
this.add(u);
},
If you want to load all users (do not limit the selection to team members and editors of a specific project) you may use Rally.ui.combobox.Combobox instead of Rally.ui.combobox.UserComboBox, and set the model to User. But to workaround a default behavior where only the current user populates the combobox, use a filter that would filter in all users. In the example below ObjectID > 0 is used. This combobox will be populated by all users independently of the project picker. This fragment is not a part of a custom app example above:
{
xtype: 'rallycombobox',
fieldLabel: 'select project',
storeConfig: {
autoLoad: true,
model: 'User',
filters:[
{
property: 'ObjectID',
operator: '>',
value: 0
}
],
sorters: [
{
property: 'UserName',
direction: 'ASC'
}
]
}
}
You'll want to use the Web Services API. Here's how I would do it...
The API doesn't allow you to specify a placement of a character in the filter, but you can require that it exists somewhere in the name, that filter would look like:
[{
property : "FirstName",
operator : "contains",
value : "A" //Whatever letter you're looking to start with
}]
Now, once the store is loaded, use a second function to filter the records to only those which start with your character:
store.filterBy(function(item) {
return item.get("FirstName")[0] === "A";
});
Hope this helps :)
Can we use Array Instead of Store for List in "sencha touch".
config:{
store: 'storeName',
scrollable: true,
itemTpl: '<div>{store_id}</div>'
}
This is config part of my store I want to use array for this list instead of store.
Please provide some code.
Thanks.
You can use a List's data config property, which is an array of any fields you want, with some that will match your itemTpl for display. It's basically a direct line into a List's store, which is created in the background for you without needing to be set. You will not need to define the store when setting the data directly.
It's probably best to set the data as an array in a defined store, and then set the store to the list, but you don't have to do it this way, and there are some cases you want to just use a simple array (see example below).
The Sencha Touch documentation shows examples of using the data array without a defined store here.
Sencha Touch 2.1.1 List data example
Ext.create('Ext.List', {
fullscreen: true,
itemTpl: '{title}',
data: [
{ title: 'Item 1' },
{ title: 'Item 2' },
{ title: 'Item 3' },
{ title: 'Item 4' }
]
});
You could also set data to an externally defined array, provided your list is created after the array is. If this turns out to be a timing problem, then you can set the data with an array at any later time using
listname.setData(someArray);
Provided you got a proper reference to listname ahead of time.
I use the dijit.form.select with the grid editor like this:
editor({
label: 'status',
field: 'status_name',
editorArgs: {
style: "width:75px;",
options: task_status
},
className: 'style8'
}, Select, "dblclick"),
when I open the select field and choose an option from the list, this returns the 'value' of selected option not the name of it.
how to get the value instead of the value?
Check the objects in your options list.
Each object should have a label and value property. The label is what will be displayed when selected.
I am using sencha touch 2 and not getting help inside sencha forum, so I hope you guys can help me.
I want to create a list with custom items. In this custom item i want to have a horizontal scrollable listview with buttons as items.
I tried to do it component.DataItem but it does no work for me.
I tried also to add an custom xtype als an item in a list, but this does not work.
I think this is a simple task but sencha touch makes it a challenge for me.
So please help me and show me, how can I get a view like shown in this picture.
Instead of a standard list you are going to want to use Component DataView. Essentially, you are going to need to first define an Ext.dataview.component.DataItem, which is then implemented into the DataView. Below is a simple example of a buttons in a DataView as referenced from the DataView guide: http://docs.sencha.com/touch/2-0/#!/guide/dataview
First create the DataItem:
Ext.define('MyApp.view.DataItemButton', {
extend: 'Ext.dataview.component.DataItem',
requires: ['Ext.Button'],
xtype: 'dataitembutton',
config: {
nameButton: true,
dataMap: {
getNameButton: {
setText: 'name'
}
}
},
applyNameButton: function(config) {
return Ext.factory(config, Ext.Button, this.getNameButton());
},
updateNameButton: function(newNameButton, oldNameButton) {
if (oldNameButton) {
this.remove(oldNameButton);
}
if (newNameButton) {
this.add(newNameButton);
}
}
});
We must extend Ext.dataview.component.DataItem for each item. This is an abstract class which handles the record handling for each item.
Below the extend we require Ext.Button. This is simply because we are going to insert a button inside our item component.
We then specify the xtype for this item component.
Inside our config block we define nameButton. This is a custom configuration we add to this component which will be transformed into a button by the class system. We set it to true by default, but this could also be a configuration block. This configuration will automatically generate getters and setters for our nameButton.
Next we define the dataMap. The dataMap is a map between the data of a record and this view. The getNameButton is the getter for the instance you want to update; so in this case we want to get the nameButton configuration of this component. Then inside that block we give it the setter for that instance; in this case being setText and give it the field of the record we are passing. So, once this item component gets a record it will get the nameButton and then call setText with the name value of the record.
Then we define the apply method for our nameButton. The apply method uses Ext.factory to transform the configuration passed into an instance of Ext.Button. That instance is then returned, which will then cause updateNameButton to be called. The updateNameButton method simply removes the old nameButton instance if it exists, and adds the new nameButton instance if it exists.
Now create the DataView:
Ext.create('Ext.DataView', {
fullscreen: true,
store: {
fields: ['name', 'age'],
data: [
{name: 'Jamie Avins', age: 100},
{name: 'Rob Dougan', age: 21},
{name: 'Tommy Maintz', age: 24},
{name: 'Jacky Nguyen', age: 24},
{name: 'Ed Spencer', age: 26}
]
},
useComponents: true,
defaultType: 'dataitembutton'
});
In your case, rather than using a button for the DataItem, you'll want to use a horizontal scrolling list. Here is an example that I found from this answer: Horizontal scrolling list
var list = Ext.create('Ext.DataView',{
store: store,
itemTpl: new Ext.XTemplate('<img src="{icon}" />'),
inline: { wrap: false },
scrollable: {
direction: 'horizontal',
directionLock: true
}
});
Note that you will probably have to use components in the second dataview as well in order to achieve your buttons with image
i have a panel which should show the "description" field of "currently activeitem of nestedlist". nestedlist uses the model having fields:
id
text
description
when user taps on any item of nestedList [on selectionchange OR itemtap&backtap], i want to change description in the panel with description of "currently activeItem of nestedList".
Is this possible?
thanks for any help/solution/pointer.
The same problem I had today, and no solution had been found with a nested list, because no single field can be taken from a Ext.data.TreeStore. One solution could be that you have lots of "if-function 'do with all the ID's and then you give each ID a text. But that's not good.
I've decided to make a simple list.
if you want I can show you my solution for the simple list
ps.: I use Sencha Touch 1.1
Update:
NotesApp.views.NaviList = new Ext.List({
fullscreen: true,
flex: 1,
layout: 'card',
scroll: false,
useToolbar: false,
itemTpl: '{text}',
store: store,
listeners: {
itemtap: function (obj, idx, el, e) {
var record = this.store.getAt(idx);
var tle = record.get('text');
index = record.get('index');
NotesApp.views.notesListContainer.setActiveItem(index, { type: 'slide', direction: 'left' });
}
}
}
});
description:
My App has the name: "NotesApp".
"notesListContainer" is a Container where all my List are displayed. "index" is an ID that I get from the store and the calls list.
Now when you tap on my NaviList you set a new ActiveItem in this Container.
thanks a lot for the reply. I also tried using simple list with one Ext.button(back button in case of nestedlist). On itemtap and buttonclink, i change list's content by
var t = new Ext.data.Store and list.setStore(t).
Please let me know if there is any other better option to do it.
