Please help me.

you can write below code in xaml.cs for Page Flip Animation .
this.TranslateTo(100, 0, 400);
await this.RotateYTo(-90, 200);
this.RotationY = -270;
this.RotateYTo(-360, 200);
await this.TranslateTo(0, 0, 220);
this.RotationY = 0;
this is basic logic for FlipAnimation you can modified if needed

Create slider with initial value zero starts at middle and left/right side -ve and +ve values

I am looking for a solution to create a custom slider in Nativescript using Angular + Typescript.
The slider should be bi-directional meaning slider should have both -ve and +ve values, 0 starting at the middle of the slider as shown in below image.
.
Thanks in advance.
Setting range in Slider with dual thumbs is supported if that works for you. Looking at the images, I don't think such behaviour is supported neither in iOS or Android. You will have to come up with your own Slider like component using drag events.

Xamarin Forms Iphone X remove padding

I've tried everything to remove the top padding in IPhone X, including setting this on the page code behind:
var safeInsets = On<iOS>().SafeAreaInsets();
safeInsets.Top = 0;
Padding = safeInsets;
and in Xaml
xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core"
ios:Page.UseSafeArea="False"
ios:Page.PrefersStatusBarHidden="True"
NavigationPage.HasNavigationBar="False"
Still getting this padding at the top. I'm probably missing or not understanding something. I've read all the Xamarin guides, many forum posts, etc. How do I get the image to go all the way to the top?

How to do a scale open animation in Flutter?

I'm trying to do this animation in flutter :
https://material.io/guidelines/motion/choreography.html#choreography-creation
My problem is that I have absolutely no idea how to do that.
As far as I know, widgets in flutter don't know their position nor the position or other widgets at all.
And you can't access context.size inside the build method.
I tried to use Hero animation to do it. Or ScaleTransition. But it's definitely not working.
You can use showMenu to dynamically show a popup menu at a given location. Consider using PopupMenuButton, which is an IconButton that automatically shows a menu when it is tapped. There's an example in the Gallery. If showMenu doesn't do what you want, you can copy the code in popup_menu.dart and customize it to make your own version. It uses CustomSingleChildLayout and PopupRoute.
If you just want to absolutely position a Material or Card on top of other elements, you can give it some elevation and use a Positioned within a Stack. You can use an AnimatedSize to adjust the element's size with a Curve. This won't interact with the back button on Android automatically, so if you want that, you may have to use addLocalHistoryEntry or PopupRoute.
If I understand you correct - you want to show square widget, and animation is not suitable at most because widget doesn't know its size.
In this case you can try MediaQuery.of(context).size.width - it returns width of your screen, so you can use it for calculating widgets size

WP7 how to accelerate animation

I'm using Storyboard with DoubleAnimation to translate Y of a StackPanel from top to bottom.
It works fine. But what I want is to accelerate it when it is about to reach bottom (like the status panel of Android).
I read this tutorial here, but it seems to apply to Silverlight only.
How to do that ?
What your looking for is an easing class.
Easing classes change speed with time. So an animation will start out slow and go fast or the opposite etc.etc.
Here's the documentation on ExponentionalEasing. Its pretty straightforward
http://msdn.microsoft.com/en-us/library/system.windows.media.animation.exponentialease(v=vs.95).aspx
However if you want more fine tuning you'll have to use KeyFrames and set the time difference between them

Positioning multiple AJAX forms in a single DIV

I have been searching for an answer for a couple days now and had no luck.
When using AJAX to bring in multiple forms into a DIV how can I position new forms not on top of the existing form?
I have a menu that calls in new forms into a working area. The new form being called in appears on top of the existing form(s). The forms are draggable but I would prefer to have the new form position itself off of the other one(s). Is there a way to do this?
I am using jQuery to handle AJAX and effects.
EDIT & ANSWER:
I just found out what was wrong. Sorry I didn't see this before. My forms were each in their own DIVs which were getting a 0 height. This is one of those facepalm moments. :P
Thanks for your responses guys. :)
BETTER EDIT:
I used the float:left advice and added in the 0 height again. Everything works great now.
If I understand what you are trying to accomplish - you could "float" your forms within your working area and just append new ones into the working area when you need to.
