DataGrid

A sortable, filterable data grid with multiselection and pagination.

Default Data Grid

The <MudDataGrid> is used to display and work with small amounts of data up to very large datasets, easily and efficiently. In it's simplest form, the data grid is just a table, displaying data from a data source. In it's most complex form, the data grid allows filtering, editing, grouping, and much more.

Using the data grid is pretty simple to start with and just requires setting the Items property to an collection of data as IEnumerable, and adding Columns.

Nr

Molar mass
1 H Hydrogen 0 1.00794
2 He Helium 17 4.002602
3 Li Lithium 0 6.941
4 Be Beryllium 1 9.012182
@using System.Net.Http.Json
@using MudBlazor.Examples.Data.Models
@inject HttpClient httpClient

<MudDataGrid Items="@Elements.Take(4)">
    <Columns>
        <PropertyColumn Property="x => x.Number" Title="Nr" />
        <PropertyColumn Property="x => x.Sign" />
        <PropertyColumn Property="x => x.Name" />
        <PropertyColumn Property="x => x.Position" />
        <PropertyColumn Property="x => x.Molar" Title="Molar mass" />
    </Columns>
</MudDataGrid>
@code { 
    private IEnumerable<Element> Elements = new List<Element>();

    protected override async Task OnInitializedAsync()
    {
        Elements = await httpClient.GetFromJsonAsync<List<Element>>("webapi/periodictable");
    }
}
Column Types

There are two main column types: <PropertyColumn> and <TemplateColumn>. PropertyColumns are typically used to display a single property defined by the parameter, Property. You would use TemplateColumns when you want to display a column without linking it directly to a property in the data source. For example, if you wanted to show a column that has action buttons. TemplateColumn cannot infer things such as Title and SortBy like the PropertyColumn.

You can pass a format string in the Format parameter on PropertyColumn to format the value for the cells.

Name Position Years Employed Salary Total Earned
Sam CPA 23 $87,000.00 $2,001,000.00
Alicia Product Manager 11 $143,000.00 $1,573,000.00
Ira Developer 4 $92,000.00 $368,000.00
John IT Director 17 $229,000.00 $3,893,000.00

        <PropertyColumn Property="x => x.Salary" Format="C" />
        <PropertyColumn Property="x => x.Salary * x.YearsEmployed" Title="Total Earned" Format="C" />
        <TemplateColumn CellClass="d-flex justify-end">
            <CellTemplate>
                <MudStack Row>
                    <MudRating Size="@Size.Small" SelectedValue="@context.Item.Rating" />
                    <MudButton Size="@Size.Small" Variant="@Variant.Filled" Color="@Color.Primary">Hire</MudButton>
                </MudStack>
            </CellTemplate>
        </TemplateColumn>
    </Columns>
</MudDataGrid>
@code {
    public record Employee(string Name, string Position, int YearsEmployed, int Salary, int Rating);
    public IEnumerable<Employee> employees;

    protected override void OnInitialized()
    {
        employees = new List<Employee>
        {
            new Employee("Sam", "CPA", 23, 87_000, 4),
            new Employee("Alicia", "Product Manager", 11, 143_000, 5),
            new Employee("Ira", "Developer", 4, 92_000, 3),
            new Employee("John", "IT Director", 17, 229_000, 4),
        };
    }
}
Advanced Data Grid

In a more advanced scenario, the data grid offers sorting, filtering, pagination and selection. There are two ways to filter the data fed into the data grid. A QuickFilter function allows filtering the items in the grid globally. Data can also be filtered by specifying column filters, enabling a more robust filtration.

In this example, we turn sorting and filtering off for the Nr column using the boolean Sortable and Filterable properties as well as hide the column options icon button by setting the ShowColumnOptions property to false (which is hidden by default). Additionally, we can override the default SortBy function for each column, seen in the Name column where we show how you can switch to a sort by the Name's length.

To hide the filter icons unless a column is currently filtered, you can set the ShowFilterIcons property to false.
