RichEditBox没有光标，也没有焦点？

Question

我在Popup里放一个RichEditBox，当Popup弹出时，我鼠标点击RichEditBox时，根本没有光标在闪烁，也无法使用键盘输入任何字母，当我点击windows键转到桌面再点击windows键进入时，RichEditBox出现，键盘也可以使用了，请问板主，为什么会这样？ TextBox也是这种情况啊，不解不解

Answer 1

这个问题暂时还没遇到过， 我这边也没重现， 是不是跟你本地的机器有些关系，我用下面的代码尝试重现：

<Grid Background="AliceBlue">
    <Grid x:Name="ContentRoot" Background="LimeGreen" Margin="100,20,100,20">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <Grid HorizontalAlignment="Center" VerticalAlignment="Top">
            <StackPanel>
                <TextBlock Text="Popup Control "  Foreground="Red"  FontSize="50" ></TextBlock>
                <Image Source="corner.jpg"  Width="400"></Image>
                <Button x:Name="PopUpButton" Content="Detail..." Height="50" Width="100" Background="Gray"  Click="PopUpButton_Click" />

                <Popup x:Name="myPopup" Margin="-34,0,-31,0" Grid.Row="2" Grid.Column="1" Height="100" VerticalAlignment="Bottom"  >
                    <Border CornerRadius="10" Background="Red" BorderThickness="2" BorderBrush="Black">
                        <StackPanel Margin="10">
                            <TextBox x:Name="PopUpText" Height="Auto" Width="Auto" FontSize="20"/>
                        </StackPanel>
                    </Border>
                </Popup>
            </StackPanel>
        </Grid>
    </Grid>
</Grid>

private void PopUpButton_Click(object sender, RoutedEventArgs e)
{
    myPopup.IsOpen = true;
    PopUpText.Text = "Free c# articles, c# tutorials, news, blogs, resources, forum for C# programming. ";
}

如果你的问题还是存在，可以给我提供一个可以重现的sample么？

Answer 2

在RichTextColumns里面，InlineUIContainer内放其它控件就会出现这种情况

Answer 3

这个我觉得是你项目的问题，我建议你建个空的app，然后试试放个RichTextColumns，看看里面的input控件能不能输入，我这边是没有问题的：

        <Popup x:Name="myPopup" Margin="-34,0,-31,0" Grid.Row="2" Grid.Column="1" Height="100" VerticalAlignment="Bottom"  >
            <Grid x:Name="columnGrid" Background="White" Width="900" Height="300">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                </Grid.ColumnDefinitions>
                <RichTextBlock Grid.Column="0" IsTextSelectionEnabled="True"  TextAlignment="Justify" 
OverflowContentTarget="{Binding ElementName=firstOverflowContainer}" 
TextIndent="12"
FontSize="12" FontFamily="Segoe UI" Foreground="#2a2a2a" Margin="20,0">
                    <Paragraph>
                        <InlineUIContainer>
                            <Border Background="Black">
                                <RichEditBox/>
                            </Border>
                        </InlineUIContainer>
                    </Paragraph>
                </RichTextBlock>
                <RichTextBlockOverflow x:Name="firstOverflowContainer" Grid.Column="1" Margin="20,0"
        OverflowContentTarget="{Binding ElementName=secondOverflowContainer}"/>
                <RichTextBlockOverflow x:Name="secondOverflowContainer" Grid.Column="2" Margin="20,0"/>
            </Grid>
        </Popup>
