Set the maximum character length of AutoCompleteBox C# WPF

Question

I am currently developing a C# WPF application. I am using the AutoCompleteBox control and I want to limit the user to only enter a limited number of characters, i.e. only be able to enter 10 characters in the autocompletebox.

I know on a normal textbox the property MaxLength would be used but this doesn't seem to be available for the AutoCompleteBox.

Answer 1

You have the property TextBoxStyle for the AutoCompleteBox

<toolkit:AutoCompleteBox>
    <toolkit:AutoCompleteBox.TextBoxStyle>
        <Style TargetType="TextBox">
            <Setter Property="MaxLength" Value="10"/>
        </Style>
    </toolkit:AutoCompleteBox.TextBoxStyle>
</toolkit:AutoCompleteBox>
