Hi Matt

Thanks for the Sample Application

I am working with xamdatagrid. and could either see the  Drag Icon  or none of the events are triggering when i select the row and start the Drag Operation.

Below is my XAML Code.

<cts:XamDataGrid x:Name="dgDeviceList2" GroupByAreaLocation="None" SelectedItems="{Binding SelectedElements, Mode=OneWayToSource}"
DataSource="{Binding AddIOComponents}" BorderThickness="1" BorderBrush="{DynamicResource {x:Static SystemColors.ActiveBorderBrushKey}}"
ScrollingMode="Immediate" Margin="0,53,0,35" AssigningFieldLayoutToItem="xamDataGrid1_AssigningFieldLayoutToItem">

<ig:DragDropManager.DragSource>
<ig:DragSource DragEnter="DragSource_DragEnter" IsDraggable="True"
DragChannels="ChannelA" DragTemplate="{StaticResource dt}" DragOver="DragSource_DragOver" Drop="DragSource_Drop"/>
 </ig:DragDropManager.DragSource>

</cts:XamDataGrid>

Do i need to do something differently for xamdata grid.

Hi Matt,

Do we need to shift to XAM GRID for achieving Drag Drop Functionality b/w two Windows.  Do we have any work around If not then we amy shift from xam data grid to xam grid.  Please advice .

Matt,

I have Implemented events as below for XAMDataGRID

DataRecordPresenter dp;
DataRecordPresenter dragOver;
private void DragSource_DragStart(object sender, Infragistics.DragDrop.DragDropStartEventArgs e)
{

     dp = Utilities.GetAncestorFromType(e.DragSource as DependencyObject, typeof(DataRecordPresenter), false) as DataRecordPresenter; 

}

//This is giving me the Dragged element and the item i need to Drop

private void DragSource_Drop(object sender, Infragistics.DragDrop.DropEventArgs e)
{

dragOver = Utilities.GetAncestorFromType(e.DropTarget as DependencyObject, typeof(DataRecordPresenter), false) as DataRecordPresenter;

Employee  targetElement = dragOver.DataRecord.DataItem as Employee  ;

Employee  sourceElement = dp.DataRecord.DataItem as Employee  ;

}

The Issue is i have  seperate  viewmodels for  each   drag  &  drop windows  and i am not able to identify the view model   of the  drop window.

I can  just create an instance of the viewmodel like

DropVm  vm = new dropVM();  and drop my target element into my observablecollection property ,  But 

our  requirement is i can drag from a source and drop into  any view which accepts my object. So i need to identify the dropTarget(it's view model).

HI,

If you are using the DataRecordPresenter you could get the viewmodel collection from that object's DataPresenter.DataSource property,
 Code Snippet:

 ObservableCollection leagues = ndr.DataPresenter.DataSource as ObservableCollection; (probably bestway)

 or you could get it from the Application.Current.Resources.

Code Snippet:

 VM vm = Application.Current.Resources["vm"] as VM;

or you could get it from the Windows resources.

Code Snippet:
 Vm vm =  Application.Current.Windows[0].Resources["vm"] as Vm;

Sincerely,

Thanks Matt  .

ObservableCollection leagues = ndr.DataPresenter.DataSource as ObservableCollection;

 worked out exactly as per our requirement.
