Hello Venkateshwarreddy,
1) we were able to answer this question yesterday, but we had a little delay before we created a post in the forum, for which we appologize. You can find our reply here: http://www.telerik.com/community/forums/thread/b311D-bggehh.aspx
2) if you have the selected child record (from GridViewDataControl.SelectedRecord), you can use the Record.RecordManager.MasterRecord property to get the parent record of the selected record; if you need to reach the child record from top, you need to use RadGridView.SelectedRecord, which you need to cast to ExpandableDataRecord. From there you can iterate through the ExpandableDataRecord.ChildRecordManagers property and examine RecordManager.Selection.SelectedRecord; if this property is not null, it represents the selected child record (if any).
Best regards,

Hello Venkateshwarreddy,
In the attached sample you can find answers to both of your questions. We made the example so that you can select rows and delete them by pressing the Delete key. In the method of Row_KeyDown, the line:
retrieves the selected child record (which represents an order). The next line:
gets the parent record and its data (the customer, to which the selected order belongs). The deletion itself happens when you simply remove the order from its collection:
You are welcome to send us any other questions you may have.
Best wishes,

Hello venkateshwarreddy,
All you need to do is write a simple style for GridViewCell:
I am attaching a sample project.

Hi Atanas,
Thankyou for your reply,
But i need for property hierarchy where when press on tab the cell should be in edit mode first for parent row and then for child rows and now to second parent row and then it child---------------.till last and once it comes to last child cell of last parent row ,again first cell of first parent row should me in edit mode.
This is similar to that of tab navigation which is happening for (hierarchy radgridview). I am using RadControls for WPF Q2 2008.

Hello venkateshwarreddy,
Currently our GridViewExpandableRow does not support cells in edit mode. We will consider this issue and may fix it in some of our next releases. Unfortunately the functionality of your scenario cannot be achieved at the moment.
Thank you for your understanding and patience.
