How can I access and manipulate individual rows in a MudDataGrid within a Blazor WebAssembly application using C#? Specifically, I want to change the background color or remove rows programmatically. Sample Project

You could access and modify the specific Person in the People IEnummerable. I'm using a List instead of an IEnummerable, just so I can use Remove, RemoveAt.
To remove a row you can use
private void RemoveRow(int index)
{
People.RemoveAt(index);
}
To change the background-color use the RowStyleFunc of the DataGrid. But before add a new Property ColorCode on Person
public record Person(string Name, int Age, string State, string ColorCode){
public string ColorCode{get; set;}
}
And use and define the RowStyleFunc of the DataGrid
<MudDataGrid T="Person" Items="@People" ColumnResizeMode="ResizeMode.Container" @ref="mudGrid" RowStyleFunc="@_rowStyleFunc">
private Func<Person, int, string> _rowStyleFunc => (x, i) =>
{
// clear all rowStyles
string style = string.Empty;
style += $"background-color:#{x.ColorCode}";
return style;
};
And finally a method to change the property ColorCode
private async void ChangeRowBackgroundColor(int index)
{
People[index].ColorCode = "FFFFFF";
}
Additionally you can also add Buttons to each row and access the person there
<Columns>
<PropertyColumn Property="x => x.Name" CellStyle="max-width: 100px; overflow-x: hidden; white-space: nowrap;" />
<TemplateColumn T="Person" TProperty="String" Sortable="false" Filterable="false" Title="Buttons">
<CellTemplate>
<MudMenu Label="Actions" Variant="Variant.Filled" DisableElevation="true"
EndIcon="@Icons.Material.Filled.KeyboardArrowDown" IconColor="Color.Secondary" TransformOrigin="Origin.TopLeft">
<MudMenuItem OnClick="@(async () => await RemovePerson(context.Item))">Remove me!</MudMenuItem>
<MudMenuItem OnClick="@(async () => await ColorPerson(context.Item))">Color Me!</MudMenuItem>
</MudMenu>
</CellTemplate>
</TemplateColumn>
</Columns>
private async Task RemovePerson(Person person)
{
People.Remove(person);
}
