Auto Refresh table

In a certain application scenario, the change of the data source needs to refresh the table component

Auto Refresh

This example demonstrates monitoring the data source in a background thread, and notifies the table component to refresh the data when the data source changes

Demo

The auto refresh function is enabled by setting the value of the IsAutoRefresh property. The default value of the AutoRefreshInterval property is 2000 milliseconds, which is the auto refresh interval, and the component's QueryAsync is called periodically. The method makes the table auto-refresh

In this example, a new piece of data is added every 2 seconds and a maximum of 10 pieces of data are maintained

@inject IStringLocalizer<Foo> LocalizerFoo

<div>
    <Table TItem="Foo"
           IsPagination="true" PageItemsSource="@(new int[] { 2, 4 })"
           IsStriped="true" IsBordered="true" IsMultipleSelect="true"
           IsAutoRefresh="true" AutoRefreshInterval="2000"
           OnQueryAsync="@OnAutoQueryAsync">
        <TableColumns>
            <TableColumn @bind-Field="@context.DateTime" Width="180" />
            <TableColumn @bind-Field="@context.Name" Width="100" />
            <TableColumn @bind-Field="@context.Address" />
            <TableColumn @bind-Field="@context.Count" />
            <TableColumn @bind-Field="@context.Complete" />
        </TableColumns>
    </Table>
</div>

@code {
    /// <summary>
    /// Foo 类为Demo测试用，如有需要请自行下载源码查阅
    /// Foo class is used for Demo test, please download the source code if necessary
    /// https://gitee.com/LongbowEnterprise/BootstrapBlazor/blob/main/src/BootstrapBlazor.Shared/Data/Foo.cs
    /// </summary>
    private List<Foo> Items { get; set; } = new List<Foo>();

    private static readonly Random random = new();

    private Task<QueryData<Foo>> OnAutoQueryAsync(QueryPageOptions options) => GenerateFoos(options, Items);

    private Task<QueryData<Foo>> GenerateFoos(QueryPageOptions options, List<Foo> foos)
    {
        // 设置记录总数
        var total = foos.Count;
        var foo = Foo.Generate(LocalizerFoo);
        foo.Id = total++;
        foo.Name = LocalizerFoo["Foo.Name", total.ToString("D4")];
        foo.Address = LocalizerFoo["Foo.Address", $"{random.Next(1000, 2000)}"];

        foos.Insert(0, foo);

        if (foos.Count > 10)
        {
            foos.RemoveRange(10, 1);
            total = 10;
        }

        // 内存分页
        var items = foos.Skip((options.PageIndex - 1) * options.PageItems).Take(options.PageItems).ToList();

        return Task.FromResult(new QueryData<Foo>()
        {
            Items = items,
            TotalCount = total
        });
    }
}

Control whether to update automatically by setting a variable

This example controls whether to automatically update by setting a variable

Demo

Enable/disable automatic update function by clicking the button

IsAutoRefresh The current value：False

<div>
    <p>
        <div>@Localizer["TablesAutoRefreshControlDescription"]</div>
        <Button Text="@Localizer["TablesAutoRefreshControlToggleAuto"]" OnClick="@ToggleAuto" /> <span><code>IsAutoRefresh</code> @Localizer["TablesAutoRefreshControlIsAutoRefresh"]：<code>@IsAutoRefresh</code></span>
