HI all,
I have created a rad pane custom control in a class say
public class CustomControl:RadPane{}<DataTemplate x:Key="ObstructionPointItemTemplate" DataType="mapLayers:ObstructionPointViewModel"> <telerik:MapPinPoint telerik:MapLayer.Location="{Binding Path=Location}" ToolTip="{Binding Label}" > <i:Interaction.Behaviors> <behaviors:PointBehavior/> <!--This behavior allows the drap and drop move--> </i:Interaction.Behaviors> </telerik:MapPinPoint> </DataTemplate>
<DataTemplate x:Key="ObstructionPointItemTemplate" DataType="mapLayers:ObstructionPointViewModel"> <telerik:MapEllipse Width="0.1" Height="0.1" telerik:MapLayer.Location="{Binding Path=Location}" Fill="{StaticResource PointFill}" ToolTip="{Binding Label}" Stroke="{StaticResource ObstructionPointColor}" StrokeThickness="2" > </telerik:MapEllipse> </DataTemplate>
var radDocument = RadDocumentHelper.GetDefaultDocument(); foreach (var item in ClausesSelectedList) { radDocument = item.ClauseData.GetRadDocument(FieldOrderNumber, RevNumber.Value); var section = new Section(); var frag = new DocumentFragment(radDocument); var docPos1 = new DocumentPosition(radDocument); docPos1.MoveToLastPositionInDocument(); radDocument.InsertFragment(frag, docPos1); }

I am creating a drag and drop dashboard page and I need some assistance with the drag and drop from RadTreeView to Grid. My goal is to drag an item from the tree which is text base, and have it render a user control at the point of drop on the Grid.
I have been looking for an example of this with no luck and was hoping this is possible. If it is possible do you have an example project that demonstrates this?
<Grid Name="cDashboardGrid" Background="White">
</Grid>
