Forums » Prof-UIS Tech Support » How much faster is CExtGridWnd over CExtTreeGridWnd Collapse All
Subject Author Date
Alastair Watts Jul 29, 2010 - 6:39 AM

CExtTreeGridWnd is slow with 35 columns * 2500 rows, this I accept so am considering changing grid controls & would like to know what kind of performance improvements to expect when using a CExtGridWnd instead.


For example, when populating the entire grid from scratch.


Thanks

The CExtGridWnd plain grid control is much faster then the CExtTreeGridWnd tree grid control. The CExtGridWnd control does not need to manage tree data structures. It also supports the virtually cached mode which allows you to initialize only displayed grid cells. This is useful when the number of rows is unlimitedly high.
