Question

嗨，我从materialDesign使用 现在我从工具箱中使用自动完成框搜索：AutoCompleteBox 我如何个性化'toolkit：AutoCompleteBox'这样的材料设计文本框？

我的文本框没有自动填充

<TextBox x:Name="SearchTextBox" 
                     materialDesign:HintAssist.FloatingScale=".56" 
                     materialDesign:HintAssist.FloatingOffset="1,-30"
                     materialDesign:TextFieldAssist.TextBoxViewMargin="1 0 1 0" 
                     Margin="16,55,16,0" HorizontalAlignment="Stretch" 
                     materialDesign:HintAssist.IsFloating="True" 
                     VerticalAlignment="Top" 
                     FontSize="24"
                     Height="70" Background="{x:Null}" Padding="6,0,20,3" Grid.ColumnSpan="2">
                <materialDesign:HintAssist.Hint>
                    <StackPanel Orientation="Horizontal" Margin="0 0 0 0">
                        <TextBlock x:Name="SearchTextBlock" FontSize="24" Padding="0,0,0,0">Search</TextBlock>
                    </StackPanel>
                </materialDesign:HintAssist.Hint>
            </TextBox>

现在是tolkit之后

<toolkit:AutoCompleteBox
                        x:Name="AutoComplete1"
                        materialDesign:HintAssist.Hint="ss"

                        Style="{StaticResource acInput}"
                        IsTextCompletionEnabled="True"
                        Height="70" Margin="16,58,16,0" Grid.ColumnSpan="2" VerticalAlignment="Top" Background="{x:Null}"/>
