I need to create tiles of well formatted buttons, something like the Windows 8 start page. Is there any toolkit available for a custom ListView which may support tile view or grid view, with some formatting and may be some animation options.
I tried creating my own custom listview but it seemed to be a complicated task.

I am not aware of a nice free tile control. DevExpress has a nice looking commercial version.
If you'd specify your exact requirements (i.e. what properties do you need configurable, what kind of animation,...) and I find the time, I would give it a whirl though.
EDIT: I've created an ItemsControl with a WrapPanel as ItemsPanel. Using the MVVM pattern, expanding the controls to your needs and your data objects should not be too difficult. Rather hard to do is the DragDrop behavior part - there certainly is still some room for improvement. I didn't include the images.

You can simply use Item Control, i). In Item Panel just give the number of rows and columns you want ii). If button you want here are to be generated dynamically just assign the list of Buttons to it.
<ItemsControl x:Name="lstButtons"
Grid.Row="0"
Grid.Column="1">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="4"
Rows="4" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Click="CLICK_EVENT_HERE"
Style="Use metro Button Style here" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
