为什么我的WPF文本框和QUOT;还挺＆QUOT;只读？ [英] Why is my WPF textbox "kinda" readonly?

问题描述

我有一个文本框在WPF是一个DataTemplate一个列表框的一部分。在该文本框我可以删除，退格键，空格键，但我不能输入新单词，字母或数字。我可以粘贴从记事本，虽然。

我在想什么吗？

解决方案

我遇到一个问题非常类似。做了一些研究之后，我发现在MSDN中列出了类似的问题：

<一个href="http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/c68d5f3c-c8cc-427d-82e3-6135d075a304/">http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/c68d5f3c-c8cc-427d-82e3-6135d075a304/

据答案后，这个问题必须与WPF和WinForms有两个非常不同的处理文字输入方式。幸运的是，上面列出的职位提供了以下解决方案：

在启动窗口，使用ElementHost.EnableModelessKeyboardInterop（窗口1）。请注意，这是一个静态方法 - 你不必实例化的ElementHost类

例如，

 窗口窗口1 =新窗口（）;
ElementHost.EnableModelessKeyboardInterop（窗口1）;
window1.Show（）;
 

这解决了这个问题对我来说。希望这有助于。

I have a text box in WPF that is part of a datatemplate for a listbox. In that text box I can delete, backspace, spacebar, but I can NOT type in new words, letters or numbers. I CAN paste from notepad though.

What am I missing here?

 <ListBox Grid.Column="1"
         ItemsSource="{Binding Details}"
         VirtualizingStackPanel.VirtualizationMode="Recycling"
         HorizontalContentAlignment="Stretch" >
            <ListBox.Resources>
                <DataTemplate DataType="{x:Type Entities:RADetailEntry}">
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>

                        <ComboBox Grid.Column="0" />
                        <TextBox Grid.Column="1" IsReadOnly="False" IsEnabled="True" 
                                 Text="{Binding Path=Description, Mode=TwoWay}" TextWrapping="Wrap"
                                 HorizontalAlignment="Stretch" VerticalAlignment="Stretch" TextAlignment="Left"  />
                    </Grid>
                </DataTemplate>
            </ListBox.Resources>
        </ListBox>

解决方案

I was encountering a problem very similar to this. After doing a little research, I found a similar problem listed in MSDN:

http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/c68d5f3c-c8cc-427d-82e3-6135d075a304/

According to the answer to the post, the problem has to do with WPF and WinForms having two very different ways of handling text input. Fortunately, the post listed above gives the following solution:

When launching the window, use ElementHost.EnableModelessKeyboardInterop(window1). Note that this is a static method - you do not have to instantiate the ElementHost class.

For example,

Window window1 = new Window();
ElementHost.EnableModelessKeyboardInterop(window1);
window1.Show();

This solved the problem for me. Hope this helps.
