How to drag ListViewItem to ScheduleView

[Rod Yager]

I have added drag capabilites to one of our listviews so that appointments can be dragged to the ScheduleView using the RadDragDropManager.

RadDragAndDropManager

 

 

.SetAllowDrag(resultListView, true);

 

 

 

 

RadDragAndDropManager.AddDragQueryHandler(resultListView, OnDragQuery);

 

For the most part everythiing works, but when I grab the scrollbar thumb on the listview and drag it down, it starts a drag operation on the selected listviewitem instead of scrolling down. Also happens when tryng to resize the listview columns.

Any idea how I can get this to react only when dragging the listviewitem within the listview?

Hi Rod,

Instead of setting the AllowDrag attached property on the whole ListView, you could set it on the ListView items, for example using ItemContainerStyle:
<ListView ...>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="telerik:RadDragAndDropManager.AllowDrag" Value="true" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

You can keep the event handler on the ListView.

By the way, we have a similar example that uses a ListBox. It is worth checking, if you haven't seen it before. Go to http://demos.telerik.com/wpf/ and navigate to ScheduleView / Drag And Drop.
