我有一个文本框，高于“普通”文本框。如果我点击文本框的“第一行”，我只能输入文字。我怎样才能点击文本框的任何部分并能够显示光标，因为如果你有一个5行文本框并且必须点击第一行输入一些文本，那就太烦人了
<StackPanel Orientation="Vertical" Margin="0,0,15,0">
<TextBlock x:Name="lblObjective" Text="Objective" Style="{StaticResource TextBlockStyle}" VerticalAlignment="Center"></TextBlock>
<TextBox x:Name="Objective" Text="{Binding ObjectiveText, Mode=TwoWay}" TextWrapping="Wrap" Height="120" Width="500"></TextBox>
</StackPanel>
编辑：
这是影响我的应用程序中所有文本框的模板。任何人都可以说我需要添加以便能够点击文本框中的任何位置并仍然得到插入符号而不必点击第一行

如果我删除整个模板一切正常（即无论我点击文本框的哪个地方，我都会得到一个carret），但其余的也丢失了。所以我遗漏了一些想法？
编辑2：
<ScrollViewer x:Name="ContentElement" BorderThickness="0" IsTabStop="False" Margin="4,0,2,2" VerticalAlignment="Top" Background="{x:Null}"/>
是问题的根源......而不是将VerticalAlignment="Stretch"设置为顶部，因此只有一行是可点击的...
答案 0 :(得分：0)
我不确定你看到的是什么，但我发现在这样一个文本框中点击文本框中的任何地方都会给它输入焦点，所以我可以开始编辑（无论你是AcceptsReturn状态的BTW，尽管你应该打开了。）
但是，如果您在框中单击的位置超出当前字符串值的末尾，则插入符号将放置在内容的末尾而不是您单击的位置。这是常见的文本框行为，我在输入它的stackoverflow中的文本框具有相同的行为。
如果您希望能够在TexBox中的任何位置开始输入，那么您将需要检测mousedown的文本位置并注入适当数量的空白。不是一件小事。
