This web page give the idea about How To Extend List Box When Reaching Last Item link
but in my case there are 2 or more list box in pivot. How to implement that?
If you use the LongListSelector (part of the Windows Phone Toolkit on WP7) instead of a Listbox, infinite scrolling is a lot easier to implement...

I want to loop Items in a list when scrolling so that will give the feeling of infinite scrolling.
In another way I mean I want if I reach the last Item of a list by scrolling down, the first Item will be under the last one so that the scrolling be like infinite.. any solutions ?
I have a large list of items, so i should request corresponding page from the server. How to catch an event, when user scrolls to the end of the listbox, so i can request another page?
The exact solutions you are looking for: http://danielvaughan.orpius.com/post/Scroll-Based-Data-Loading-in-Windows-Phone-7.aspx
You're thinking about data virtualization. Shawn Oster wrote a really good explanation to this here. To sum it up, it's not the ListBox that is managing your data, but your custom IList implementation, that is able to fetch new items each time a new data chunk is needed.
you can just check the vertical offset if is greater than the scrollable height, the user is at the bottom of the list, fire the request for another page as needed.
The best approach is to use the LongListSelector. It's available from the Windows Phone Toolkit for Windows Phone 7 or it's built-in on Windows Phone 8. It performs better than the built-in ListBox and has more features.
A post from the official Windows Phone Developer blog (from October 2012) gives all the details and tells how to setup infinite scrolling.
I am designing an application for Windows Phone 7, and I want to create a UI element where a user can select an item from a large list, by using a text search. Are there any existing controls that provide something like this?
I have found an example of something that does what I want, minus the text search.
Alternatively, is there some sort of other control that provides similar usability -- allowing a user to select an item from a list, but providing some way to narrow it down?
Edit:
Is there a list of built-in WP7 controls with documentation?
I think you are looking for an AutoCompleteBox - http://www.windowsphonegeek.com/articles/Data-Binding-the-Windows-Phone-Toolkit-AutoCompleteBox
On the IPhone, the map control allows you to switch between a list mode and map mode easily. I've been trying to find examples of this for WP7 but am at a loss.
Is there a best practice for implementing a list of objects on a map?
If not, do we just do it manually, I.E. Save the dataset and display it as a listbox or something?
If you do it manually, where is the best place to put a button to switch you between the 2 screen styles? I feel like that app bar isn't right.
I don't want to copy the IPhone UI standard and have a button in the title bar, although I'm running out of options.
For one "best practice" I'd take a look at how the default Bing Maps app works - it provides a "results list" text menu item accessible from the ApplicationBar - and this is displayed via a full screen dialog (at least I think that's what it is).
However, that is only one "best practice" - I don't think their UI is perfect for all apps.
Application bar is fine, just make sure the buttons are in the same positions for each bar and that toggling views 10 times does not require pressing Back 10 times to go to the previous page, maybe use a different page transition so it doesn't feel like every other transition on the app.
Is there a way to extend the number of items that appear in the VB6 combo instinsic control, when it drops down? I have about 10 items and I'd like to show them all.
This code at Karl Peterson's classic VB website will automatically size the combo box to match the number of elements:

I've used the code here, and can confirm that it works as advertised. If you remove the last SendMessage call, it won't actually dropdown until the user clicks on it.
