How would you implement infinite scrolling using sencha touch? In other words, either register a callback that is called when a user scrolls near the bottom of a list to load more data or do something more involved.
Ext.ux.Livegrid is an ExtJS user extension that can help you...

As anyone can notice it, in the schedule external drag drop demo , someone can drag the event from the TreeView list and when it get near to the right page edge then the page scrolls to the right.
Here is a screenshot showing it.
It's occuring also in our app and it's rather annoying.
We wish there will be a fix for this issue.
Greetings from Syncfusion Support.
We have checked your reported problem that dragging a TreeView node that produces the scroller in the output web page. Currently, we don’t have any property to prevent the scroll when dragging a TreeView node. However, we have already considered this as a feature from our end. It will be included in our Volume 2 Release which is expected to be released in June 2020.
Track the below link to know the feature status.

But, you can resolve your issue by setting the target for dragArea of TreeView’s drag object in the created event. When setting the target, you can drag the element only inside the target element. It prevents the element from scrolling exceeding that element.
Please, check out the sample with the above explained solution.
Sample: https://stackblitz.com/edit/react-jqzozo-gqpyve?file=index.js
onCreate(){
this.treeObj.dragObj.dragArea = "body";
}
How can I achieve a horizontally list (contains multiple containers) automatically scroll up and down like something like this link?
I already made the list the problem is how to achieve the auto scroll horizontally.
Every label in Codename One supports this, it's called "tickering" and you can just call startTicker() to start the tickering for a label. You might also need setTickerEnabled(true).
I am working on Protractor tests. Recently my web page changed where the terms and conditions are inside a textbox. Button Submit works only when the user scrolls through the textbox and clicks on Agree button. I tried the following option to scroll down but it is not scrolling down. Any help is greatly appreciated.
var scrollbar = element(by.id('terms-conditions'));
var checkbox = element(by.id('checkbox'));
scrollbar.click()
browser.executeScript('arguments[0].scrollIntoView()', scrollbar.getWebElement());
browser.executeScript('window.scrollTo(0,670);')
checkbox.click();
I followed the below link too but no luck.
Protractor: Scroll down
The second js execute statement you are using contains Window.scrollTo which references an open window in a browser. and using it only scrolls the complete window but not the pop-ups that appear inside a browser window
Refer here for documentation on Window.scrollTo
Normally terms and conditions shows up in a pop-up or may be a div and hence Window.scrollTo doesn't work
there are two ways you can do it
SOLUTION 1: use Jquery scrollTop() to scroll inside a specific webElement
Step 1: Identify the exact div that holds your terms of Service scroll bar
Step 2: Refine your js statement by trying directly in Chrome console
$('.modal-body').scrollTop() -> This returns the current position of scroll
$('.modal-body').scrollTop(10000) -> This sets the value of top position
Step 3: Incorporate this in your protractor script
browser.executeScript('$('.modal-body').scrollTop(10000)');
You can professionalize this by passing the element & scroll amount as arguments. Refer here
SOLUTION 2; The best way I see to submit a pop-up is not to deal with interface but to deal with the 'form' element behind it. Similar to how we deal with file uploads.No fuss & effective
May be try something like this, by making button visible first and then submit form
browser.executeScript is an asynchronous call, so you will need to put it into the controlFlow so that it will complete before clicking the checkbox:
scrollbar.click();
browser.controlFlow().execute(function() {
browser.executeScript('arguments[0].scrollIntoView()', scrollbar.getWebElement());
browser.executeScript('window.scrollTo(0,670);');
});
checkbox.click();
Can we have a ExtJs5 Tree Grid Panel which provides below features:
Inifinite Scroll so that rows are rendered with some limit on scroll and not all records at sametime.
On Click of any root node of a particular row (could be 2/3 levels), i can fire a ajax call to populate a grid/form inside the expanded row.
Please provide your expert suggestions in this regard asap.
Thanks !
1. yes you can use infinite scrolling for TreeGrid. Checkout the example
2. If you want expand a row and inside that row you want a form or a grid, then I would say that is nearly impossible. You can only handle this with a custom renderer for the gridpanel and even with this you must create it via Ext.create and render it into the treepanel.
Why dont use something like this: https://fiddle.sencha.com/#fiddle/l26
I'm trying to implement a view that requires a response from the server to update itself, so I'd like to 'dim' the container and show a spinner while it's asynchronously loading information from the server and then 'undim' when it's finished.
I've seen the same effect from the background of a Msg/Panel and would like to implement exactly the same thing with a spinner in the middle.
I think you want to use the regular extjs loadMask, let us know if you need help using it.
