如何防止Richtext框扩展？
如何防止Richtext框扩展？
提问于 2016-07-30 02:35:10
我的应用程序中有一个RichTextBox，当我向其中添加文本时，文本框会垂直展开。如果应用程序被拉伸，我希望它动态调整大小，但如果向其添加文本，则不会扩展。
下面是我所有的xaml代码：
<Grid Background="#FF1F1F1F">

我把它改成了DockPanel，在添加文本时，它的大小仍然会变大(见上文)
下面是另一个项目，在这个项目中，它不会随着添加的文本而增长：
<Border Grid.Column="0" Margin="5,5,0,5">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<DockPanel Grid.Row="0" >
<RichTextBox Name="txtMessageHistory" Margin="5" Background="#FF343434" Foreground="#FFDEDEDE" VerticalScrollBarVisibility="Visible">
<RichTextBox.Resources>
<Style TargetType="{x:Type Paragraph}">
<Setter Property="Margin" Value="0"/>
</Style>
</RichTextBox.Resources>
</RichTextBox>
</DockPanel>
<StackPanel Grid.Row="1" Orientation="Vertical">
<TextBox x:Name="ChatTextBox" Background="#FFDEDEDE" Foreground="Black" Margin="5,5,5,5" />
<StackPanel Orientation="Horizontal">
<Button x:Name="SendMsg" Content="Send msg " Click="btnSendMessage_Click" Margin="0,0,5,0"/>
<Button x:Name="ClearMessages" Content="Clear messages" Click="ClearMessages_Click" Margin="0,0,5,0"/>
<Button x:Name="SendMsg_Ping" Content="Send Ping" Click="SendMsg_Ping_Click" Margin="0,0,5,0" />
<Button x:Name="SendMsg_E2PRequest" Content="Send E2P Request" Click="SendMsg_E2PRequest_Click" Margin="0,0,5,0"/>
<Button x:Name="SendMsg_MARequest" Content="Send Mon App Request" Click="SendMsg_MARequest_Click" Margin="0,0,5,0"/>
<Button x:Name="SendMsg_PluginStatusRequest" Content="Send Plugin stat Request" Click="SendMsg_PluginStatusRequest_Click" Margin="0,0,5,0"/>
</StackPanel>
</StackPanel>
</Grid>
</Border>再试一次：
移除网格和Dockpanel -尺寸仍在增长：
<Border Grid.Column="1" BorderThickness="1" Padding="5" BorderBrush="#FF878383" CornerRadius="10">
<Grid>
<RichTextBox Name="ManagerNotice" Background="#FF343434" Foreground="#FFDEDEDE" >
<RichTextBox.Resources>
<Style TargetType="{x:Type Paragraph}">
<Setter Property="Margin" Value="0"/>
</Style>
</RichTextBox.Resources>
</RichTextBox>
</Grid>
</Border>尝试(最后一次，这是有效的)
当我显式地将高度设置为某个数字时，它的行为
<DockPanel Grid.Row="1" >
<RichTextBox Height="100" Name="ManagerNotice" Margin="5" Background="#FF343434" Foreground="#FFDEDEDE" VerticalScrollBarVisibility="Visible">
<RichTextBox.Resources>
<Style TargetType="{x:Type Paragraph}">
<Setter Property="Margin" Value="0"/>
</Style>
</RichTextBox.Resources>
</RichTextBox>
</DockPanel>回答 1
