Descripción general
El resaltado de registros en los datos de Blazor se puede alternar estableciendo la IsRowHoverEnabled
propiedad booleana de la cuadrícula Blazor. Tenga en cuenta que esto está habilitado de forma predeterminada.
Además, el color se puede configurar estableciendo la propiedad de cadena RowHoverBackground
en un valor hexadecimal.
Fragmento de código
A continuación se muestra cómo habilitar el resaltado de filas en la cuadrícula de datos de Blazor y se aplica el color azul:
<IgbDataGrid Height="100%" Width="100%"
DataSource="DataSource"
IsRowHoverEnabled="true"
RowHoverBackground="#bfbfff" />
