当用户更改对话框的大小时,如何设置wpf文本框以自动调整大小？
<Window x:Class="MemoPad.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Background="LightGray"
Title="Window1" Height="350" Width="700" >
<StackPanel Orientation="Vertical">
<Menu DockPanel.Dock ="Right">
<MenuItem Header="Find" x:Name="gMNuFind" />
</Menu>
<Button Content=" Find "
Margin="5,10,5,5"
x:Name="gBuFind"
/>
<TextBox Margin="0,0"
HorizontalAlignment="Left"
VerticalAlignment="Top"
MinHeight="270" MinWidth="690"
x:Name = "gTBxInfo"
TextWrapping="Wrap"
AcceptsReturn="True"
ScrollViewer.VerticalScrollBarVisibility="Auto"
/>
</StackPanel>
解决方法
或者将StackPanel更改为Grid
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Background="LightGray"
Title="Window1" Height="350" Width="700" >
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<Menu>
<MenuItem Header="Find" x:Name="gMNuFind" />
</Menu>
<Button Grid.Row="1" Content=" Find "
Margin="5,5"
x:Name="gBuFind"
/>
<TextBox Grid.Row="2" Margin="0,0"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
MinHeight="270" MinWidth="690"
x:Name = "gTBxInfo"
TextWrapping="Wrap"
AcceptsReturn="True"
ScrollViewer.VerticalScrollBarVisibility="Auto"
/>
</Grid>
</Window>
