Hi,

Code Snippet:

BindingList<SalesPerson> persons=new BindingList<SalesPerson>();

.... code that populates the persons.

CollcetionViewSource cvs=new CollectionViewSource();

cvs.Source=persons;

cvs.View.CurrentChanged += new EventHandler(CollectionView_CurrentChanged);

public void CollectionView_CurrentChanged(...)

{

does something....

}

<igDP:XamDataGrid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" DataSource="{Binding Path=cvs.View}

Question:

Currentchanged is not executing when i move between record in the XamDataGrid.

Hello rameshbaburengarajan,

It has been a while since you have made your post, in case you still need of support I will be glad to help with this matter. I suppose the other community members can benefit from this answer as well. So my research on your issue shows that the reason that the CurrentChanged event does not fire when you navigate through the records in the XamDataGrid is that theXamDataGrid’s IsSynchronizedWithCurrentItem property is not set to True. You can set this property to True and the event should fire while you move between the Records in the XamDataGrid.

If you need any further assistance please do not hesitate to ask.

Sincerely,

Krasimir

I'm having the same problem as the original poster and I have IsSynchronizedWithCurrentItem set to true. What am I doing wrong?

By the way, what is the correct way to paste code into a post? Sorry for the ugly formatting.

<

igDP:XamDataGrid DataSource="{Binding Path=ViewManager.Items, Mode=TwoWay}"

AutoFit
="True"

ScrollingMode
="Immediate"

Name
="FWPGrid"

Loaded
="FWPGrid_Loaded"

Theme
="IGTheme"

GroupByAreaLocation
="None"

Grid.Row
="1"

IsSynchronizedWithCurrentItem
="True"

>

public

class CollectionViewManager<T> : INotifyPropertyChanged

{

protected IList
<T> _source;

protected DataPager
_dataPager;

public IList<T> Source { get { return
_source; } }

public ICollectionView Items { get; set
; }

public T CurrentItem { get { return
(T)Items.CurrentItem; } }

public T OriginalCurrentItem { get; set
; }

public bool HasItems { get { return
Items.SourceCollection.OfType<T>().Count() > 0; } }

public event Action<DataPagerEventArgs
> PageIndexChanged;

public DataPager DataPager { get { return
_dataPager; } }

public bool UseServerSidePaging { get; set
; }

public
CollectionViewManager()
{

_source =

new List
<T>();
Items =

CollectionViewSource
.GetDefaultView(Source);
Items.CurrentChanged +=

new EventHandler
(Items_CurrentChanged);
}

void Items_CurrentChanged(object sender, EventArgs
e)
{

throw new NotImplementedException();
// Should crash here but this event is never fired

}
