Hello,I want to design an app to track expenses. I have a problem with display all transactions in one day. I want to do something like this:
May 25 $68.00
--------------------------------------------------------------
Food $25.00
Gift $25.00
Telephone $18.00

May 24 $43.00
--------------------------------------------------------------
Food $20.00
Hobbies $23.00

The problem is that I can only display each transaction on its own date (ex. Food $25 May 25). I don't know how to group all transactions in the same date.Does anyone have suggestion?

Thanks in advance.

Try reading some about stackpanels, they might be what you are looking for

Thank DBDev for replying.
I think I didn't explain clearly enough.
I have a class Transaction.cs which has properties (date, category, amount). I used ListBox (like griddata) to display all transactions in form of table.
As I mentionned in the first post, I can only display a single transaction like:
Food $20.00 May 24
Hobbies $23.00 May 24

So, I want to display all transactions in one date as I mentionned in the first post like this:

May 24
Food $20.00
Hobbies $23.00

Thanks.

You could take advantage of the grouping capabilities of the LongListSelector control. The code for implementing grouping differs between Windows Phone 7 and Windows Phone 8. Either way, the process is basically the same: you have one big datastore and you first have to separate out everything into groups (choose a "primary key", in this case, the date), easily done by using LINQ (you need to make a "group" class though), and then you add the collection of groups as the ItemSource of the LongListSelector.

Thanks a lot Catholic Tech Geek, that sounds like what I looked for.
Thanks again.

And a good example of this in action (although with images but the grouping is basically the same principle) is on MSDN at:
