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...
