My Events in the Code behind are as follws.

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;
}

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

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

ComponentList targetElement = dragOver.DataRecord.DataItem as ComponentList;

ComponentBase sourceElement = dp.DataRecord.DataItem as ComponentBase;

viewmodel vm = dragOver.DataPresenter.DataContext as viewmodel ;

// My Business logic  continues

}

int overIndex;
private void DragSource_DragOver(object sender, Infragistics.DragDrop.DragDropMoveEventArgs e)
{

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

overIndex = dragOver.Record.VisibleIndex;

}

My requirement is   i should highlight entire row when i start dragging.

    Hello,

     

    Thank you for your post. I have been looking into the functionality that you are trying to achieve and I can suggest using the DataRecordPresenter as DragSource and DropTarget. By doing so you will have the Record highlighted when you drag another record over it. I have created a sample application for you, that demonstrates how you can implement the approach I have mentioned.

     

    Please let me know if you need any further assistance on the matter.

     

    Sincerely,
