Hi team,
I have the implementation of Drag & Drop b/w two XAMDatagrids as below in xaml

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,

Hi krasimir,
The Solution works fine but i have an another requirement here.
Based on the Id in the collection i am setting the back ground of my child records as below
<cts:XamDataGrid.Resources> <Style TargetType="{x:Type igDP:DataRecordPresenter}"> <Setter Property="Background"> <Setter.Value> <SolidColorBrush Color="{Binding Path=DataItem, Converter={StaticResource bgColorConverter}}" Opacity="0.3"/> </Setter.Value> </Setter> </Style> <!--<Style TargetType="{x:Type igDP:DataRecordCellArea}"> <EventSetter Event="MouseDown" Handler="StartDragging"/> </Style>--> </cts:XamDataGrid.Resources>
I have a converter class to change the back ground of child record in the hierachial grid which i am setting it to red.
When i drag that record i need to change the back ground of that particular record to transparent.
I have tried some of the below code
DataRecordPresenter dragsource = Utilities.GetAncestorFromType(e.DragSource as DependencyObject, typeof(DataRecordPresenter), false) as DataRecordPresenter
int startIndex = dragsource .Record.VisibleIndex;
CellValuePresenter.FromCell((dgDeviceList2.Records[startIndex] as DataRecord).Cells[1]).Background = Brushes.Yellow; DataRecordPresenter.FromRecord(dgDeviceList2.Records[1] as DataRecord).Background = Brushes.Yellow;
The problem here is it is changing the parent's background but not the child or the dragged item's back ground.
How should i go with this ?.
Below Code worked.
dragsource.background = Brushes.White, has done what i wanted.
Thank you for your email. I am very glad that you have managed to solve the issue that you were having. Please let me know if you need any further assistance on the matter.
