View Full Version : scroll list to the top on refresh

18 Jul 2010, 12:44 AM
Hi, i've a list dynamically populated from an ajax call and it work fine.
There are only six rows visible, so when i have more than 6 i can scroll to the bottom , and here
is the problem.
If i scroll to the bottom of 20 rows, when i refresh the list with other data (3 rows for example) the
list remain to the bottom and i don't see anything until i manually scroll to the top.
Is there a way to avoid this?

thanks so much

After you do the code to refresh the list or store you can use

timeline.scroller.scrollTo({x: 0, y: 0}, true); // scroll to the top

where timeline is the id of the list.

Hello there,

when using Sencha Touch 0.93beta I get the error that the property scroller is undefined for both list and panel.
What am I missing?

Thanks in advance and for the great community support

Probably either

a) You haven't setup scrolling on your panel
b) The panel isn't rendered yet

a) scrolling is set to 'vertical'
b) the AJAX request triggering the alert is made well after the initial loading of the tabpanel I use
Can you give me a simple example where is is used in a small demo application?

tabletStartupScreen: 'tablet_startup.png',
phoneStartupScreen: 'phone_startup.png',
icon: 'icon.png',
glossOnIcon: false,

onReady: function() {
var html = [];
for(var i = 0; i < 500; ++i){
html.push('line ' + i);

var p = new Ext.Panel({
fullscreen: true,
scroll: 'vertical',
html: html.join('<br />')
x: 0,
y: 1000
}, true);

My mistake was somewhere else, but you still helped me figure it. Cheers!
