Hello HARSH,

 Could you please give me the implementation to SetItemsSource?

Below is the code snippet6 for SetItemsSource Method.

public void SetItemsSource(IEnumerable dataSource)

 

{

 

 

 

rView.ItemsSource = dataSource;

 

}

Here instead of IEnumerable i tried passing object as well as Observable Collection

Thanks,
Harsh

Hi HARSH,

 This is more peculiar than I thought. Could you please open a support ticket and attach your application so that we can study it?

Can you please let me know where i need to open that support ticket.
Do i need to log that to

Public Issue Tracking SystemBETA

.

[HARSH]

I figured out the issue.
It was due to access modifier of class.
custom Class need to have public modifier.
