How can I display data from a List of value tuples in a DataGrid

Tuples are awkward - they don't use properties but fields (RadzenDataGrid prefers properties). Also you can't get a tuple member by its name via reflection. tupleType.GetField("one") does not work - it has to be tupleType.GetField("Item1").

Still you can display your tuple collection like this (with some limitations listed below the code):

    <RadzenDataGrid Data="@foo">
        <Columns>
            <RadzenDataGridColumn TItem="(int id, double one, double two)" Title="Id">
                <Template>
                    @context.id
                </Template>
            </RadzenDataGridColumn>
            <RadzenDataGridColumn TItem="(int id, double one, double two)" Title="One">
                <Template>
                    @context.one
                </Template>
            </RadzenDataGridColumn>
            <RadzenDataGridColumn TItem="(int id, double one, double two)" Title="Two">
                <Template>
                    @context.two
                </Template>
            </RadzenDataGridColumn>
        </Columns>
    </RadzenDataGrid>
@code {

    List<(int id, double one, double two)> foo = new() { };

    protected override void OnInitialized()
    {
        foo.Add((1, 2, 3));
    }
}

Here are a few RadzenDataGrid features which rely on properties and hence won't work with tuples:

  • Sorting (can be implement with custom code by handling the LoadData event)
  • Filtering (can be implemented as custom code too)
  • Editing (not sure if you need it)
