How to improve performance when using formatting and styling for the cells based on data?

In SfDataGrid, you can customize the Cell/Row style based on the data in the following three ways,

1. StyleSelector
2. DataTriggers
3. Customizing property in Style using Converters

StyleSelector

You can customize the Cell/Row based on content by using CellStyleSelector/ RowStyleSelector, but it affects the performance while styling more number of columns or rows. Therefore, this is not a recommended way for styling the SfDataGrid for more number of columns or rows. You can use this StyleSelector according to your necessity.
