You need to capture the mouse down and mouse up events. Drag & drop is not supported directly. If you google drag and drop silverlight, you will find plenty of information.

What? I'm sorry but I didn't understand any of that question. Could you form the words fully please - I don't read text speak, and I ignore questions that are like this. Plus, it's considered bad form to say that it's urgent - if it's that urgent, you should pay for a support call; this is a volunteer only forum.

Hi,
I have a StackPanel that contains a ListView
<StackPanel>
<ListView x:Name="theList" BorderBrush="{x:Null}" Grid.Column="1" Grid.Row="1" ItemsSource="{Binding PhoneBook.FilteredPhoneBook}" SelectionMode="Extended" Focusable="False" ItemTemplate="{StaticResource PhoneBookPostTemplate}" HorizontalAlignment="Center" ItemContainerStyle="{StaticResource ListViewItemStyle1}" >
....
</ListView>
</StackPanel>
The items in the ListView can be expanded if the want to edit it (the selected items height is then increasing). When the edit is finished I get a white space in the buttom of the list. It looks like the StackPanel has grown when I edit the item.
Example (but the list is vertical..)
Before edit: "X X X X X X"
After edit: "X X X X X X "
Question:
Can I remove the white space without setting OnPropertyChange("ContactBook"), which will repaint the list. The problem is that it takes some time to update the list with OnPropertyChange("ContactBook") since it can be many items in the list.
Regards
Magnus

From your example, it looks like an extra item is being added to the ListView??
When you fire the OnPropertyChange does it remove the space/item you are mentioning ?

Hi,
Thanks for quick answer!
In the debugger I can see that the StackPanel.Height is increasing when I edit an item. When the edit is finished the StackPanel keeps this new height. And thats why the list now contains a white space in the end.
Example:
Item X/Y shows this information in the list
Name:...
Address:...
But in edit mode you can type in (now is the stackpanel.Height increasing since the item contains more information, this is what I try to show with YYY)
Name:...
Address:...
Member id: ...
Gender: ...
Before edit: "X X X X X Y"
Edit: "X X X X X YYY"
After edit: "X X X X X Y "
Yes when I fire OnPropertyChange the white space is removed. But is there another way to decrease stackpanel.Height? It takes to much time to update the list with OnPropertyChange.

Can you share the ItemTemplate and ItemContainerStyle ? What is your datasource -a List, ObservableCollection?

My datasource is a generic List.

I have run into a similar issue before and I think it was solved with a call to InvalidateMeasure().

Building a PaintBrush in Silverlight is not that hard (the painting part).
Where you would get troubles is in export the image to jpeg or printing, you have to duplicate your drawing code in the server side using GDI+ (well that's if you use an starndard hosting, some people has made some cheats using WPF on the server side).
