Hi Ross,

This issue is a bug in Drag-Drop framework. Right-click should not initiate drag and this is the one causing the issue.

The hotfix is being prepared for this issue, you can get it on the latest hotfix release. Let me know if you encounter issue when right-click is not used.

About the UXListBox settings, you actually do not need to insert additional behavior.

<i:Interaction.Behaviors>

<Intersoft:DropTargetBehavior AllowDropItem="True"/>

</i:Interaction.Behaviors>

You just need the AllowDropItem="True" property. Most of drag-drop related feature is configurable directly in UXListBox, so no need to insert additional behavior.

Regards

Andry

Hello all,

We were experimenting with drag n drop and one of the testers decided to click on an item with a right mouse click then drag around in circles, eventually, the program stopped responding, another time it threw an exception.

Here's the listbox def:

<Intersoft:UXListBox x:Name="lbMyMemberships" ItemsSource="{Binding OCMyMemberships, Mode=TwoWay}" SelectedItem="{Binding CurrentMyMemberships, Mode=TwoWay}" Margin="2" Height="331" ImageMemberPath="IconName" DisplayMemberPath="Description" AllowDropItem="True" AllowMoveItem="True" AllowRemoveItem="False" ItemContentType="ContentAndImage" ItemImageHeight="32" ItemImageWidth="32" ItemImageStretch="Fill" Style="{StaticResource UXListBoxTransparentStyle}" >

<i:Interaction.Behaviors>

<Intersoft:DropTargetBehavior AllowDropItem="True"/>

</i:Interaction.Behaviors>

</Intersoft:UXListBox>

We are using MVVM. Is there a way to capture this condition and prevent the user from doing this?

Thanks,

Ross
