Right to Left

RTL provides an option to switch the text direction and layout of the NumericTextBox component from right to left. It improves the user experiences and accessibility for users who use right-to-left languages (Arabic, Urdu, etc.). To enable RTL NumericTextBox, set the EnableRtl to true.

The following code example initializes the NumericTextBox component in Chinese culture.

@using Syncfusion.Blazor.Inputs
@inject HttpClient Http

<SfNumericTextBox TValue="int?" Value=10 Locale="zh" EnableRtl="true"></SfNumericTextBox>

@code {
    protected IJSRuntime JsRuntime { get; set; }
    protected override async Task OnInitializedAsync()
        this.JsRuntime.Sf().LoadLocaleData(await Http.GetJsonAsync<object>("blazor-locale/src/zh.json")).SetCulture("zh");
