In my app, I have a fixed sidebar that can scroll its overflow content vertically. When I get to the end of the scrollable area, the scroll event bubbles to the main window. I would like to prevent that bubble from happening. I've tried a couple things
<div id="sidebar" can-scroll="scrollMe">
<div id="sidebar" can-onscroll="scrollMe">
I have the scrollMe function in my component's scope, but neither one of the above options binds.
How do I bind to scroll event, or is it even possible using a can-EVENT?
Looks like this was my mistake. The can-scroll event works. My CSS code was set up to allow scrolling on the parent element.
So the simple answer is yes, it's possible to use can-scroll.

I need Modal Page appears with "slide from bottom and cover (NOT push) current page" transition.
I set parameter animated of showModal method, but nothing changed.
How implement such transition for Modal Page? Android platform.
it's bug github.com/NativeScript/NativeScript/issues/5989
I have kinda hacky stuff, wrapping my elements with AbsoluteLayout and give it a high top value like '800',
and in navigatedTo function make transition animation with the negative value of the top attribute. In your case you would use left attribute and make transition over x.
Another solution that looks better in the UI, adding a custom component that would act as your modal, wrap your page elements with AbsoluteLayout, add your custom component when you need to show your modal, and apply the previous animation hack to it.
Tip: You can set the actionBarHiddin = true if you want to your custom component to overlay the full screen.
Tip: async/await and then would be very useful for the smoothing matters.
There's a collapsible sidebar on my webpage. When I collapse it, I want the svg element on the page to resize to take up all of the new blank space.
The function that resizes the svg is working. However, it is not being triggered when the sidebar is collapsed.
I have tried:
d3.select("#mydivHoldingSVG").on("resize", MyResize)
Where #mydivHoldingSVG is a <div> and MyResize is the function to resize the svg.
When the sidebar is collapsed, the <div> element increases in size (as inspected via Google Chrome developer view), which I thought constituted a "resize".
If the window is resized, that is, if I use:
d3.select(window).on("resize", MyResize)
Then the svg resizes correctly.
I have looked at the list of standard events to see if one can be applied to the div element (#mydivHoldingSVG) but I'm not seeing an obvious "when a div element changes" event.
Is there an eventListener that can be added on a <div> element being resized or changed?
The gist is that you should do it another way: the resize event only pertains to the window and will not fire on any other element.
The cleanest way to solve this problem would be call MyResize when you call whatever function is collapsing your sidebar, rather than trying to indirectly listen for the sidebar being collapsed.
I'm essentially making a 'shopping cart' UI and I want it so that when the user hits the 'Add' button, a little tiny box-label appears at the bottom of the screen that says 'Added Item' or something like that.
My question is how to do that with my current set up. I am currently using a nested Grid inside of a Scroll view for the main content of the page. I want the box-label to fade in at the bottom of the screen and stay located at the bottom of the screen ontop of everything else even if you scroll, until the animation fades.
Now i figure it doesn't make sense to add it into the grid since the grid's end will be out of view in the scrolling part of the scroll view, and same for the Scroll View. I am considering nesting the entire scroll view inside of a stack layout but i fear the button will just be located at the end of the stack layout under the scroll view instead of on TOP of the scroll view. How do you recommend I achieve this effect?
I prefer not to use a custom renderer if possible due to my lack of experience in the three separate platforms.
Thanks
Make vertically oriented stack layout. When you need to add you animation add it programmatically to the stack. When it finishes remove it from stack. Your scroll view will not affect animation
This is not my day. I've just deleted every object from my previously completed view controller to start over because I can't get a simple scroll view to scroll. I've got a view controller that is embedded in a navigation controller. I put scroll view inside the view controller and then put two text fields inside the scroll view, one field at the top and one at the bottom.
First of all, when I run this, it won't scroll. What is the point of the scroll view if it won't scroll?
Second, I can't figure out how the relationship between the navigation bar and the scroll view works. Is the scroll view behind the navigation bar? Is it below the navigation bar? In the story board, it looks like it is behind the bar, but when I run it, my text field is pushed down so far that it looks like it is behind it.
Here are a couple of screen shots. To say that I am frustrated is an understatement. Thanks for any help getting me out of my circular problem. I appreciate it.
And here is how it looks when I run it. Notice how far down the top text field gets drawn. Also note that you cannot see the bottom text field. I am unable to scroll to this. What gives?

Scroll views won't scroll by default unless their contentSize exceeds their bounds. You can force it to scroll anyway by setting alwaysBounceVertical to YES.

Yes, in iOS 7, by default, a scroll view will start at y = 0, behind the nav bar. You use the contentInsets property to push it down. The view controller has an automaticallyAdjustsScrollViewInsets property that can handle this for you.
I've been struggling for weeks trying to crack this nut so I'm not sure if it's impossible, or if it's my lack of coding chops... or both. I'm not a programmer and I'm a newbie to Dojo Toolkit.
I have a site using the BorderContainer layout. I'm trying to create an effect where I can use a button to open and close a dropdown type box that will contain controls. I need this dropdown to be hidden on page load, and then open when you click the button.
My problem is that when I open the dropdown, it pushes the content pane below it off the bottom of the browser window. I need the lower ContentPane to stay fit within the remaining space of the browser window when the dropdown opens. Additionally, I want the dropdown to sit outside of the scrollable container for the content below it, which is why I have it set up to sit outside a nested BorderContainer below it.
I've created a simplified version of the code to demonstrate my challenge (see link below). If you load the page you can see the center ContentPane scrolls the content. But, if you then click on the button, a dropdown div expands above the content. Then when you scroll, you'll notice that you can't see the full pane because it's in no-man's-land below the bottom of the browser window. I assume that because the div is set to display:none on load, it's size is not accounted for on page load. Then, when you open it by pressing the button, it's size is additive and the pane below doesn't know how to resize or account for the new element.
I've tried using the visibility attribute, but that leaves a gap for the div when it's still closed. I've tinkered with some code that controls the height that shows promise, but each of my dropdown boxes will be different sizes so I'd prefer that the height be set to "auto" rather than a specified pixel size.
Does anyone have any idea how I can accomplish this so that the lower pane will fit in the space without pushing off the screen?
Here's a sample of the page:
http://equium.com/scaffold.html
(I had some problems trying to insert the full HTML page here as a code sample so if that's a preferable way to handle it, and someone can let me know the best way to embed all of that code, I'd appreciate it.)
Thanks is advance, I'd really apprecaite anyone's feedback.
You might want to take a look at dojox.layout.ExpandoPane (though be warned I think it has only worked properly for top and left regions for a while).
Also, I'd suggest simplifying/altering your layout a bit. See example here:
http://jsfiddle.net/taFzv/
(It'd probably need some tweaking to get exactly what you want.)
The real issue you're having is probably that the BorderContainer has no idea that parts of the view resized. ExpandoPane takes care of that by telling the BorderContainer to re-layout after its animation completes.
It works under IE8.0. When dropdown box open, just keep pressing mouse from page and drag to bottom, you could see the content was pushed to out of page. It looks the browser could not detect it and could not add it to "scroll bar" account.
I would suggest taking out all BorderContainers except your top level one, the one with mainPage as the id.
Place your {stuff here} div into the mainPage BorderContainer, after the ContentPane with the Close/Open button. Make sure you make it dojotype dijit.layout.ContentPane, set up layoutpriority, and set region to top. Set the height to 0/x when clicking the Open/Close button, instead of setting display.
Try your page again. If that doesn't fix it, you probably need, a call to layout, resize, or both to indicate to the BorderContainer that it needs to evaluate all its children and size the "center" pane properly. Something like dijit.byId("mainPage").layout(); Do this any time someone presses the Close/Open button, after you have changed the height of any BorderContainer children.
Maybe the dijit.form.DropDownButton would fit your needs. When click the button a tooltip is displayed that can be filled with any content you want. Just as you specified, the dropdown tooltip is only displayed when you click the button, and it doesn't mess with the underlying layout at all. The tooltip sits "on top" of the page.
