You can create a high-performance Grid control with unlimited number of items. The Grid control has the following methods for the virtual mode handling:
- EnableVirtualMode: enable virtual mode and set a callback function
- SetVirtualRows: define the number of grid rows in the virtual mode
Please take a look at the BCGPGridExample application ("Virtual List" tab and "Grid Control | Virtual Mode Test" dialog) to see how to add to the grid 1 billion items.
In addition, the virtual mode has been implemented in the database grids. Run the BCGPDBGridDemo example to see this feature in action.
