I need a support init cells in the CFilteredTreeGridWnd class from FilteredGrids sample by ADODB::_RecordsetPtr like in AdoRecordsetView sample project. Can you get me a sample how can I do this?

By the way, how I can change the CFilteredTreeGridWnd.Init() function for fillings cells if I have opened recordset ADODB::_RecordsetPtr in my project?

The AdoRecordsetView sample app demonstrates how to implement a virtually cache-able CExtGridWnd window with dynamic on-the-fly data uploading from external databases using ADO APIs. The virtually cache-able mode is supported by the CExtGridWnd control. It’s not supported by the CExtTreeGridWnd control. Tree grids always use data completely stored in memory. So, you should simply enumerated data records and insert all of them into tree grid. If you have many data records, then switch to CExtGridWnd control and apply ready-to-use code from the AdoRecordsetView sample app.
