MudBlazor - Blazor Component Library

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	Sign	Name	Position	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

    {
        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.

Visual Styling

The <MudDataGrid> has many built in properties to change its style and also allows for custom styling as well.

Row level classes and styles can be applied using the RowClass and RowStyle properties respectively. To style rows according to the data of the row, you would use the RowClassFunc and RowStyleFunc properties. For even finer grain control, you can style at the header, cell and footer level as well by using the CellClass, CellStyle, CellClassFunc, CellStyleFunc, etc. properties. However, the header and footer do not have the Func properties since they are not needed.

Editing

The <MudDataGrid> allows editing the data passed into it. Setting the ReadOnly property to false and the EditMode property to turns editing. There are two different edit modes: Cell and Form. Form displays a form in a popup when editing. Cell is more like excel where each cell is ready to edit and as you make edits, they are applied to the data source. To disable editing on a column, set its IsEditable property to false.

By default, the built in editing in the data grid automatically supplies the proper input component for each cell. However, this can be overidden by supplying an <EditTemplate>. Inside the template, you have full control over the editing. Take a look at the Position column below.

Nr	Sign	Name	Position	Molar mass
1	H	Hydrogen	0	1.00794
2	He	Helium	17	4.002602

The <MudDataGrid> allows you to group data by column. Setting the Grouping property to true will turn on grouping which will add a menu item in the column options to toggle grouping of that column. To disable grouping on a column, set its Groupable property to false.

Sorting

The <MudDataGrid> allows you to either disable sorting entirely, sort by single column or by multiple columns via the SortMode property. The default (SortMode.Multiple) allows sorting on more than one column (Hold Ctrl-Key) while clicking on a header column to extend the sort operation to another column.
Clicking on the column header while Alt-Key is pressed, will un-sort a column (or remove it from the set of sorted columns) when multiple sorting is enabled. In the case of multiple sorting, a small index-number next to the sort direction arrow will indicate the order in which columns are sorted.
When mode is set to SortMode.Single, only a single column can be used for sorting at a time. Using another column for sorting will automatically un-sort any former sorted column. In single mode, the number indicator next to the direction arrow will not be shown.

In both active modes, single columns can be excluded from sorting by setting the Sortable property to false for that column. When SortMode is set to SortMode.None sorting is disabled globally and setting the Sortable property on a column has no effect.

You can also use the SortBy parameter on a TemplateColumn to allow sorting on that column.

Changing the SortMode at runtime will reset any former sort orders on all columns.

Advanced Sorting

The <MudDataGrid> allows you to provide your own Comparer for advanced sorting. Keep in mind that the Comparer will use the same object passed by the SortBy parameter. If SortBy is not supplied, it will use the column item for its comparison. You can also manually call SetSortAsync on the DataGrid while passing your Comparer. Comparer must implement IComparer<object>. This example uses a natural sorting algorithm to sort strings with numbers properly.

Name	Value	Misc
1	42	555
10	73	7
2	11	4444
1_10	33	33333
1_2	99	66
1_11	44	1111111

Filtering

The <MudDataGrid> supports filtering with several different DataGridFilterModes by setting the FilterMode property. DataGridFilterMode.Simple is the default where all filters are managed in one popover in the data grid. It allows you to set multiple filters at one time for multiple different columns. In DataGridFilterMode.ColumnFilterMenu mode, there is a dedicated popover for each column. Lastly, DataGridFilterMode.ColumnFilterRow allows you to inline the filtering behavior directly into the data grid.

Is it possibile to define the case sensitivity when filtering string values by setting the parameter FilterCaseSensitivity.

Advanced Filtering

It is possible to customize filtering by utilizing the <FilterTemplate> available on the <MudDataGrid> as well as each <Column>. In the example below, the Sign column is customized.

Inside of the <FilterTemplate> on the data grid while using DataGridFilterMode.Simple, the context is set to the data grid's FilterDefinitions to allow for customizing the filtering behavior.

When using the <FilterTemplate> in the column specific filter modes, the context is a DataGridFilterMode.Simple which gives access to several helpful properties and actions. For example, the current FilterDefinition related to the column is available as well as several actions to make it easier to implement custom filter behavior such as ApplyFilter and ClearFilter.

Row Detail View

The The <MudDataGrid> allows you to create hierarchical layouts. To do that the HierarchyColumn has to be added in the Columns definitions.

You can customize the icon to toggle the RowDetail and also disable the toggle button.

Resizing

The <MudDataGrid> allows you to resize columns interactively when ColumnResizeMode is not set to None, which is the default. There are two modes for resizing: ResizeMode.Container and ResizeMode.Column. ResizeMode.Container resizes the entire data grid while ResizeMode.Column only resizes columns using available space within the data grid.

Nr	Sign	Name	Position	Molar mass	Category
1	H	Hydrogen	0	1.00794	Other

    }
}

Data Aggregation

The <MudDataGrid> allows you to aggregate data in several different ways. Data aggregation happens in the footer of the grid for the most part. By setting an AggregateDefinition, you can easily add a quick built-in aggregate or choose to tailor the display to your needs. There are 6 different AggregateTypes that can be used with the AggregateDefinition: Avg, Count, Custom, Max, Min and Sum. For more control over the data aggregation, you can choose the AggregationType.Custom and supply your own function which will return a formatted string to display. Lastly, for complete control over the data aggregation including the look and feel, you use <FooterTemplate> which has it's context set to the CurrentPageItems.

Aggregation is automatically applied to groups when the data grid is grouped by a column. Try it out by grouping the Status column!

Sticky Columns

The <MudDataGrid> allows you to make a column stick to the left or right. Setting the StickyLeft or StickyRight properties to true will make those columns "sticky". You must turn on HorizontalScrollbar to see the columns stick to either side.

There are a couple of things to keep in mind with sticky columns. First, if there are not enough columns and data to force the data grid to scroll, you will not see the columns stick, and that is by design and simply how sticky works in CSS. Secondly, there is nothing stopping you from making multiple columns sticky, but it will not have the effect you presumably intend. Instead, each column will be sticky when it reached the left or right side of the data grid and will overlap the sticky column before it.

Name	Age	This is a really long column ...	Salary
Sam	56	...	50000.00
Alicia	54	...	75000.00
Ira	27	...	102000.00
John	32	...	132000.00

@using System.Net.Http.Json

<MudDataGrid Items="@_users" HorizontalScrollbar="true" Bordered="true" Dense="true">
    <Columns>
        <PropertyColumn Property="x => x.Name" StickyLeft="true" />

@code {
    public record User(string Name, int Age, string FillerColumn, decimal Salary);

    private IEnumerable<User> _users = new List<User>
    {
        new User("Sam", 56, "...", 50_000.00M), 
        new User("Alicia", 54, "...", 75_000.00M),

        new User("John", 32, "...", 132_000.00M),
    };
}

Virtualization

The items in the <MudDataGrid> can be virtualized to provide better rendering performance. Setting the Virtualize property to true will cause the items to be rendered virtually. You must restrict the height for virtualization to work.

@using System.Net.Http.Json
@using MudBlazor.Examples.Data.Models

<MudDataGrid Items="@_items" Virtualize="true" FixedHeader="true" Height="350px">
    <Columns>
        <PropertyColumn Property="x => x.Column1" />
        <PropertyColumn Property="x => x.Column2" />
        <PropertyColumn Property="x => x.Column3" />
        <PropertyColumn Property="x => x.Column4" />
        <PropertyColumn Property="x => x.Column5" />
    </Columns>
</MudDataGrid>

@code {
    public record Model(string Column1, string Column2, string Column3, string Column4, string Column5);

    private List<Model> _items = new List<Model>();

    protected override void OnInitialized()
    {
        for (var i = 0; i < 20000; i++)
            _items.Add(new Model($"Value_{i}", $"Value_{i}", $"Value_{i}", $"Value_{i}", $"Value_{i}"));
    }
}

Observability

When loading the <MudDataGrid> with a collection that implements INotifyCollectionChanged, changes to the underlying collection will automatically be reflected in the <MudDataGrid>.

Sam	56	Normal	50000.00	3/5/2005 12:00:00 AM	False

CultureInfo

DataGrid Culture (CultureInfo) property is used to display and editing/filter columns data. Each <Column> can define his own culture, to allow specify its format individually.

Name	Age	Amount (es-ES culture)	Total (invariant culture)
Sam	56	2,3	3.2
Alicia	54	4,5	4.9
Ira	27	2,1	2.5
John	32	5,9	6.1

@using System.Globalization

<MudDataGrid Items="@_items" Filterable="true">
    <Columns>
        <PropertyColumn Property="x => x.Name" />
        <PropertyColumn Property="x => x.Age" />
        <PropertyColumn Property="x => x.Amount" Title="Amount (es-ES culture)" Culture="@(new CultureInfo("es-ES"))" />
        <PropertyColumn Property="x => x.Total" Title="Total (invariant culture)" Culture="@CultureInfo.InvariantCulture" />

    };

    public record Model(string Name, int? Age, double? Amount, double? Total);
}

Column Reordering

To enable Column Reordering via Drag and Drop, set the DragDropColumnReordering parameter to true. Columns can override this parameter with their DragAndDropEnabled parameter if necessary. In the example all but two fixed columns can be reordered by dragging their header onto another column header to swap places. On mouse-over the draggable columns show their DragIndicatorIcon and when dragging a header over another column header, it will signal its ability to swap places by changing its text color. The drag-over effect can be customized by setting parameters DropAllowedClass and DropNotAllowedClass to your own CSS classes.

Nr (fixed)	Sign	Name (fixed)	Position	Molar mass	Category
1	H	Hydrogen	0	1.00794	Other
2	He	Helium	17	4.002602	Noble Gas (p)
3	Li	Lithium	0	6.941	Alkaline Earth Metal (s)
4	Be	Beryllium	1	9.012182	Alkaline Metal (s)
5	B	Boron	12	10.811	Metalloid Boron (p)
6	C	Carbon	13	12.0107	Nonmetal Carbon (p)
7	N	Nitrogen	14	14.0067	Nonmetal Pnictogen (p)
8	O	Oxygen	15	15.9994	Nonmetal Chalcogen (p)
9	F	Fluorine	16	18.998404	Halogen (p)
10	Ne	Neon	17	20.1797	Noble Gas (p)
