Blazor Grid - Other examples
Use Blazor Bootstrap grid component to display tabular data from the data source. And it supports client-side and server-side filtering, paging, and sorting.
Cell formating #
To format the cell data, use
ToString method and format strings. Refer: How to format numbers, dates, enums, and other types in .NETTIP
Example: @context.Salary.ToString("N2").
