WPF DataGrid Performance

The WPF DataGrid is a fantastic component but it can get pretty slow with a large number of rows or columns.

Try these quick-and-easy changes to improve the performance:

• Set the following attributes to enable row and column virtualization:

EnableColumnVirtualization="True"
EnableRowVirtualization="True"

• Set a fixed column width - this reduces the number of layout recalculations that are required when rendering:

ColumnWidth="100"
