Telerik WinForms UI: A Comprehensive Guide to Building Modern Windows Applications

1. UI Virtualization: In RadGridView and RadListControl, always enable EnableVirtualization = true. This prevents the creation of UI elements for off-screen rows.
2. Suspend Layout: When batch-updating properties (adding 1,000 columns), wrap the update in BeginUpdate() and EndUpdate() to prevent 1,000 redraws.
3. Use Unbound Mode for Static Data: If you don't need two-way data binding, use unbound mode. It reduces memory overhead significantly.

// Enable virtual mode for 1M rows
radGridView1.VirtualMode = true;
radGridView1.RowCount = 1000000;
