Grid Hierarchical & Inheritance

Hi I have a tabPageClass which is inherited from Syncfusion TabControlExtn-tabpage, it contains another class that is inherited Syncfusion datagrid. Now I am instancing the tabpage class in a Form, and adding it to a tabcontrol(which is also syncfusion inherited class) three times. And i have two methods in Datagrid for setting dataset & formatting. One is ordinary and other one is Hierarchical. When I try to do this in a form having single tabcontrol and single Grid hierarchical formatted it is working fine. When I try to have 3 grids in a tab control in three different tab pages One hierarchical grid is not working system crashing. Where I am missing? If any of my sentences is not clear, please mail me back Regards Rajaraman Calsoft, INDIA

Easiest would be to have a small sample project that demonstrates the problem and we can debug into it. You can upload a small sample project by creating a support incident at www.syncfusion.com/support. Thanks, Stefan
