Converters

Converters are essential for binding input elements to your model.

When you bind a non-string value to a <MudTextField<T> > or any other input element that supports a value of type T, then a Converter converts that value to string for display and converts the user's input back to T. This happens automatically without you having to do anything special.
MudBlazor's DefaultConverter<T> is pretty capable as you can see below but sometimes you'll want to use your own conversion functions. This page is all about that.

DefaultConverter<T>

The default converter converts all primitive types and their nullable variants to and from string. Edit the textfields below to see how the default converter handles different values depending on the type.

DateConverter

By default, the DefaultConverter uses your local culture settings. If you want to change that, you can either set the Culture of individual inputs or converters, or change it globally by setting Converters.DefaultCulture to your desired CultureInfo at application start.

If you want to configure the date format of a DateTime value, you can set the Format parameter of <MudTextField>.

Let's format the same date in different ways:

@using System.Globalization;

<MudGrid>
    <MudItem xs="12" sm="6" md="4">
        <MudTextField Label="en-US" Variant="Variant.Outlined" Culture="@en" @bind-Value="date" />
    </MudItem>
    <MudItem xs="12" sm="6" md="4">
        <MudTextField Label="de-AT" Variant="Variant.Outlined" Culture="@de" @bind-Value="date"></MudTextField>
    </MudItem>
    <MudItem xs="12" sm="6" md="4">
        <MudTextField Label="zh-CN" Variant="Variant.Outlined" Culture="@cn" @bind-Value="date"></MudTextField>
    </MudItem>
    <MudItem xs="12" sm="6" md="4">
        <MudTextField Label="en-US: dddd, MMM dd" Variant="Variant.Outlined" Culture="@en" Format="dddd, MMM dd" @bind-Value="date" />
    </MudItem>
    <MudItem xs="12" sm="6" md="4">
        <MudTextField Label="de-AT: dddd, dd. MM." Variant="Variant.Outlined" Culture="@de" Format="dddd, dd. MM." @bind-Value="date"></MudTextField>
    </MudItem>
    <MudItem xs="12" sm="6" md="4">
        <MudTextField Label="zh-CN: yy年MM月dd日" Variant="Variant.Outlined" Culture="@cn" Format="yyyy年MM月dd日" @bind-Value="date"></MudTextField>
    </MudItem>
</MudGrid>
@code {
    CultureInfo en = @CultureInfo.GetCultureInfo("en-US");
    CultureInfo de = CultureInfo.GetCultureInfo("de-AT");
    CultureInfo cn = CultureInfo.GetCultureInfo("zh-CN");
    DateTime date = DateTime.Now;
}
