I want to display this in to advanced datagrid.. w.r.to parent task Id..

[-] Project1
[-] Documentation
DOC-Preparation
DOC-Review
DOC-Rework
[-] Design
DES-Preparation
DES-Review
DES-Rework
[+] Coding



ie;, Project1 is the first row...
When expanding project!1 it should display the other rows whose parent taskId is 0(Project1's serial No).

Thanks in advance
