            <ComboBox Grid.Column="1" x:Name="cmbInsuredType" Text="{Binding InType, Mode=OneWayToSource}" Margin="35,4,165,0" Width="200" Grid.ColumnSpan="3" Grid.Row="1"/>

        </Grid>

我想根据输入的用户输入水平而不是垂直地调整名称xaml文本框控件（增长/缩小）。请帮助

Answer 1

删除文本框上的宽度，并在文本框

上设置HorizontalAlignment =“Stretch”

Answer 2

您可以从以下代码开始：

<TextBox Height="20" TextChanged="TextBox_TextChanged" MinWidth="50" Padding="0" />

在您的代码中

private Size MeasureString(string candidate, TextBox tb)
{
  var formattedText = new FormattedText(
      candidate, CultureInfo.CurrentUICulture, FlowDirection.LeftToRight, new Typeface(tb.FontFamily, tb.FontStyle, tb.FontWeight, tb.FontStretch), tb.FontSize, Brushes.Black);

  return new Size(formattedText.Width, formattedText.Height);
}

private void TextBox_TextChanged(object sender, TextChangedEventArgs e)
{
  if (sender is TextBox)
    ((TextBox)sender).Width = MeasureString(((TextBox)sender).Text, (TextBox)sender).Width;
}

如何根据输入扩展/调整xaml文本框的大小？
