Hi Telerik Team,

I was using Rad Gridview for WPF to build a hierarchial view of contents. I have already reported few formatting issues that I faced during my development. But this seems to be a critical issue as it happens on the Databinding, proudcing totally inconsistent results and presenting the data inappropriate. Please do have a look at the screenshots I have attached.
The issue seems to happen only after, when all the nodes or row details are expaned at a time. This does not happens when I expand and collapse single node or row detail at a time. Even it does not seems to happen when I had two nodes or row details expanded. When the number of expanded nodes or row details at a time are more, the data bound to the child grids are inappropriate, meaning the data relation ship between the parent and child records are collapsed, resulting in displaying non-related child data.

DataBindIssue1.png - Shows the gridview loaded with initial data
DataBindIssue2.png - Shows the correct child data being displayed when the nodes are expanded (only 2 nodes expanded)
DataBindIssue3.png - Shows the correct Row Details bounded to the child grid
DataBindIssue4.png and DataBindIssue5.png - show the incorrect child data displayed after I have expanded and collapsed all the nodes at a time (and expanded few row details in the child grids of different parent rows)

The row details are implemented with add/edit options but neither of the operation is performed during this testing. I was about to do a demo with this application, but stopped because of these issues. Can you please provide me a possitive reply sooner?

thanks and regards...
NK

Hi Telrik Team,

I got no reply for the issues that I'd posted. Even I cannot conclude whether this is a problem at my code part or a know bug at your side.

Can you please reply to this at the earliest?

thanks & regards...

Hello Yenkay,
Indeed we have recognized this as problem. We will investigate this further in order to provide solution to this issue.
Meanwhile you can use simple workaround by turning off row virtualization. I have prepared application that demonstrates usage of hierarchy with row details.

If this sample does not represent your exact case or you have any more questions do not hesitate to contact us.

Kind regards,
