In extension of the first question I asked here How to Scroll to the Bottom of a ListBox when Items are Added where I discovered how to scroll a ListBox to the most recently added item, I'd like to be able to take this one step further and add in some sort of slide in animation to newly added items. How might this be possible? Any starting points would be of great help.
I use Telerik's DataBoundListBox, it supports add/remove animations in a easy declarative way.

I'm looking for some animations for my listbox. When i swipe right on a listbox item, it goes to the bottom of the listbox and ideally, all the other listitems should gracefully go up. Similarly when I swipe left, that item gets deleted, and as before, the items needs to reposition.
I have implemented the functionality on swipe right and swipe left. But it is not graceful due to the lack of animations. How do I create those? Could someone share some blogs or msdn articles on how to create them. Or just give me some intro on this. I have never done animations before.
Thank you,
The Windows Phone Toolkit has some transition effects that could help you. I assume you already know it since you implemented the swipe functionality unless you didn't use the provided gestures from it??
so I have a question regarding my stackpanel I'm using.
Basically when I keep adding items (expenses/earnings) the into the stackpanel I will eventually be short on navigational space and ultimately the older entries be overwritten.
So at the moment it has a maximum of five entries that can be added and displayed all at one. However If I add another entry/item/expense etc the first entry will be removed/not seen in the stackpanel
So in the picture, as soon as a 6th item is added the 1st item in the list will be removed/not visible
Kind of hard to explain, hope you can help!
More code:
pivotItem XAML
ItemsList control XAML
put the stackpanel in a scrollviewer. This should allow for automatic resizing as more data is added and you can scroll through it as well
Just like the UITableView on iphone.
users can remove or move a row on UITableView.
There is only one button to switch the UITableView to editing mode.
but for listbox on wp7 , I need 3 buttons, one for removing the selected row, one for moving the row up, one for moving the row down.
Welcome any comment
The Windows Phone ListBox doesn't support these features out of the box, but it would be possible to add them yourself using a DataTemplate.
Here's a blog post about creating a custom DataTemplate for your ListItems.
At a high level, you'll need to create a template that contains:
Enter edit mode button
Delete button
Sort up/down buttons
Then in your code, you'll need to toggle the visibility of the delete and sort buttons, as well as handle user clicks on each of the buttons. Doable, but a fair amount of work.
In my opinion, a better option would be to use a approach that's different from what you might be used to but is more familiar to Windows Phone users: the ContextMenu. This control allows you to pop up a menu when the user performs a long touch (tap-and-hold) on an item.
Here's a good tutorial about incorporating this control into your app.
Take a look at re-order ListBox here. It shows how to retemplate the ListBox.
For removing on item, you just need to remove its data source item. See how to use ObservableCollection.
If you want to show effect when an item is removed, use Event Triggers for the Unloaded event.
I want to modify a stack panel, so when an item is removed from it all the items under it slides in animation upwards to fill the missing gap. what is the approach I need to take in order to achieve this ?
Use ListBox instead, and have its ItemsPanel be a StackPanel. Then, modify the style of the items to include an animation in AfterLoaded, BeforeLoaded, and BeforeUnloaded visual states.

I am trying to give a ListBox drag and drop ordering functionality and I have hit a wall. I got it to work when I specify the list box items in xaml but it does not work when I bind to a list it no longer works because the items are no longer of a listboxitem type.
I found this code http://blog.dobaginski.com/josh/?p=52 that allows me to get the underlying ListBoxItem but I can't get the mouse move event to fire.
I have went through other tutorials but have not been able to find one that deals with a ListBox. Has anyone done this with a ListBox.
The events I am using are SelectedChange, MouseMove, and LeftMouseButtonUp (I think that name is right). I am not using LeftMouseButtonDown because I couldn't get it to fire.
As far as i know you cannot get at the listbox item container when using data binding. YOu could in Beta 1.
You also cannot set a mouse event handler in the style, you must use a data template, just so you know.
You will likely have to use the mouse move event from a parent element, probably the UserControl or main layout control that hosts the listbox.
State changes and animations need to be in the style though so... you still cant get at the listbox item, just the element inside it in the data template.
Oh and if doing drag and drop HitTest is now protected so that will make the Drop harder.
since today you can download the final 2.0 version of Silverlight with some add ons, check the Scott's web log
I've been trying to do the same thing in WPF,
but have only found many buggy implementations.
One person has guided me towards the blog of Beatriz Costa,
and from what I remember she's one of those rare geniouses,
so I suggest you read that as well... I know I will
