我通过 XAML<找到了一个简单的解决方案/a>.在 ComboBox 资源中，我们可以设置文本框的样式并通过 setter set maxlenth.

I found an easy solution via XAML. In ComboBox resources we can set the style for a textbox and via setter set maxlenth.

<ComboBox Name="comboBox" Width="100" IsEditable="True">
    <ComboBox.Resources>
        <Style TargetType="{x:Type TextBox}">
            <Setter Property="MaxLength" Value="yourValue"/>
        </Style>
    </ComboBox.Resources>
</ComboBox>
