Bootstrap Blazor enterprise-level UI component library

Enterprise-level component library based on Bootstrap and Blazor

AutoComplete

The input box autocompletes the function

Basic usage

By setting Items data collection when the user types information that is automatically displayed

Demo

In this example, type 123 strings to display the viewing effect, automatically give the component initialization to the auto-prompt dataset, and the dataset does not change

@inject IStringLocalizer<AutoCompleteNormal> Localizer

<p>@Localizer["Description"]</p>
<div style="width: 200px;">
    <AutoComplete Items="@StaticItems" IsSelectAllTextOnFocus="true"/>
</div>

@code {
    private static List<string> StaticItems => new() { "1", "12", "123", "1234", "12345", "123456", "abc", "abcdef", "ABC", "aBcDeFg", "ABCDEFG" };
}

Blur queries and ignore case

By setting the IsLikeMatch value settings to turn on fuzzy matching of collections, you control whether case is ignored by setting the IgnoreCase

Demo

In this example, type the abc string to display the viewing effect and select all matches in the collection that contain abc and have the same case

@inject IStringLocalizer<AutoCompleteLikeMatch> Localizer

<p>@Localizer["Description"]</p>
<div style="width: 200px;">
    <AutoComplete Items="@StaticItems" IsLikeMatch="true" IgnoreCase="false" />
</div>

@code {
    private static List<string> StaticItems => new() { "1", "12", "123", "1234", "12345", "123456", "abc", "abcdef", "ABC", "aBcDeFg", "ABCDEFG" };
}

Custom prompt message

By setting the NoDataTip value setting automatically completes the custom prompt message that appears when the data is not found

Demo

In this example, type 567 strings because the autocomplete information center does not display custom prompt information - <code>the data you want is not found</code>

@inject IStringLocalizer<AutoCompleteNoDataTip> Localizer

<p>@Localizer["Description"]</p>
<div style="width: 200px;">
    <AutoComplete Items="@StaticItems" NoDataTip="@Localizer["NoDataTip"]" />
</div>

@code {
    private static List<string> StaticItems => new() { "1", "12", "123", "1234", "12345", "123456", "abc", "abcdef", "ABC", "aBcDeFg", "ABCDEFG" };
}

Custom candidates

By setting up ValueChanged callback method reorganizes the data collection based on the data entered by the user before prompting for information

Demo

In this example, type any string to display the viewing effect, and automatically complete the component's dynamic changes from the newly obtained prompt dataset based on the string you type

@inject IStringLocalizer<AutoCompleteValueChanged> Localizer

<p>@Localizer["Description"]</p>
<div style="width: 200px;">
    <AutoComplete Items="@Items" ValueChanged="@OnValueChanged" />
</div>

@code {
    private readonly List<string> _items = new();
    private IEnumerable<string> Items => _items;
    private Task OnValueChanged(string val)
    {
        _items.Clear();
        _items.Add($"{val}@163.com");
        _items.Add($"{val}@126.com");
        _items.Add($"{val}@sina.com");
        _items.Add($"{val}@hotmail.com");
        return Task.CompletedTask;
    }
}

The label is displayed

When a component binds in both directions, it automatically determines whether label text is displayed based on the conditions

Demo

The pre-label explicit rules are consistent with the BootstrapInput component of the [portal]

Bidirectional binding displays labels

Bidirectional bindings do not display labels

Customize DisplayText

Custom city

@inject IStringLocalizer<AutoCompleteShowLabel> Localizer

<p>@((MarkupString)Localizer["Description"].Value)</p>
<Divider Text="@Localizer["Divider1Text"]" Alignment="Alignment.Left" style="margin: 2rem 0;"></Divider>
<ValidateForm Model="@Model">
    <AutoComplete Items="@StaticItems" @bind-Value="@Model.Name" ShowLabel="true"/>
</ValidateForm>
<Divider Text="@Localizer["Divider2Text"]" Alignment="Alignment.Left" style="margin: 2rem 0;"/>
<AutoComplete Items="@StaticItems" @bind-Value="@Model.Name" ShowLabel="false"/>
<Divider Text="@Localizer["Divider3Text"]" Alignment="Alignment.Left" style="margin: 2rem 0;"></Divider>
<AutoComplete Items="@StaticItems" @bind-Value="@Model.Name" DisplayText="@Localizer["AutoText"]" ShowLabel="true"/>

@code {
    private Foo Model { get; set; } = new Foo() { Name = "" };
    private static List<string> StaticItems => new() { "1", "12", "123", "1234", "12345", "123456", "abc", "abcdef", "ABC", "aBcDeFg", "ABCDEFG" };
}

Debounce

Set Debounce value turn on debounce

Demo


<AutoComplete Items="@StaticItems" OnSelectedItemChanged="OnSelectedItemChanged"></AutoComplete>
<BlockLogger @ref="Trace" class="mt-3"/>

@code {
    [NotNull]
    private BlockLogger? Trace { get; set; }

    private static List<string> StaticItems => new() { "1", "12", "123", "1234", "12345", "123456", "abc", "abcdef", "ABC", "aBcDeFg", "ABCDEFG" };
    private Task OnSelectedItemChanged(string val)
    {
        Trace.Log($"Value: {val}");
        return Task.CompletedTask;
    }
}

OnSelectedItemChanged

Click the dropdown item or Enter trigger the callback

Demo

In this example, please type any string to display the viewing effect. Within the anti shake time, the auto completion component will only send the results to the back end after the last entry, which will greatly improve the performance

@inject IStringLocalizer<AutoCompleteDebounce> Localizer

<p>@Localizer["Description"]</p>
<div style="width: 200px;">
    <AutoComplete Items="@Items" ValueChanged="@OnValueChanged" Debounce="500"/>
</div>

@code {
    private readonly List<string> _items = new();

    private IEnumerable<string> Items => _items;

    private Task OnValueChanged(string val)
    {
        _items.Clear();
        _items.Add($"{val}@163.com");
        _items.Add($"{val}@126.com");
        _items.Add($"{val}@sina.com");
        _items.Add($"{val}@hotmail.com");
        return Task.CompletedTask;
    }

}

ItemTemplate

Set ItemTemplate for customer the dropdown item

Demo

<AutoComplete Items="@StaticItems">
    <ItemTemplate>
        <div class="d-flex align-items-center">
            <i class="fa-solid fa-bell"></i>
            <span class="flex-fill ms-2">@context</span>
        </div>
    </ItemTemplate>
</AutoComplete>

@code {
    private static List<string> StaticItems => new() { "1", "12", "123", "1234", "12345", "123456", "abc", "abcdef", "ABC", "aBcDeFg", "ABCDEFG" };
}

        </BootstrapInputGroup>
    </div>
</div>
