Hi, I'm using DataPresenter in my WPF application. In that same application i'm using xamlChart. I passing the same dataview to both the controls as datasourceWhen the user did the filter in xamldatapresenter, how to get that filtered data and refresh the xamlchart in the application. Can i get the filtered data in RecordFilterChanged or Changing event ? If yes can you provide the sample code for that . Thanks in advance
Hello,
I have been looking into your requirement and the XamDataGrid has exposed methods just for that, that you can use right away:
xamDataGrid1.RecordManager.GetFilteredInDataRecords();
xamDataGrid1.RecordManager.GetFilteredOutDataRecords();
I suppose you are going to need the Records’ underlying data class objects in order to use in the chart. You can get them by casting the Record class to DataRecord and access its DataItem property.
Please let me know if you require any further assistance on the matter.

Peter ,
I need some help regarding the binding data to the chart. I'm using xamdatachart(scatter series) binding to dataview and binding xaxis xmemberpath and ymemberpath to the fields. how come its not working that way.
Then i tried to use the obervablecollection using a x,y values in theat class and passing to that . its working fine.
my question why can't i pass the sql data view bind to xamdatachart, is there any limitation.
My second question is you answer to me about the filtering datagrid and then pass the filtered to the xamdatachart. If i understood correctly , I will receive the oberservable collection from the filter method . can i pass that collection directly to the xamdatachart . do i need to convert to any data type for binding to the xamdatachart.
My Third question is you answer my question in another support activity. regarding the chart control interactivity.
In order to get the data behind the DataPoin on a mouse click you can handle the XamDataChart's MouseLeftButtonDown event like so:
private
void xamDataChart1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e){Marker marker= Utilities.GetAncestorFromType(e.OriginalSource as DependencyObject, typeof(Marker), false) as Marker;if (marker != null){var data = ((e.OriginalSource as FrameworkElement).DataContext as infragistics.Controls.Charts.DataContext).Item;
THis event fires for every click on the chart. i need to fire a event for data point click on scatter series chart . i tested your code that you send, every time the marker is null. i need to debug more with your code.
I appreciate your help peter, we bought the infragistics control last few months back, thats why lot of question regardint the binding and simple question.
I attached the xaml that i'm using for chart control and c# binding
quoteChart.DataContext = d; chartScatterSeries.XMemberPath = xAxis1; chartScatterSeries.YMemberPath = yAxis1;
d is the sql dataview. xaxis1 and yaxis1 are the string with the field names.
Thanks for you help
I ended up using GetFilteredInDataRecords(). It's working for me now. Thanks.
