TextBox not receiving touch input

Question

Dear all,

I have build a simple WPF application with a simple list box which have as a test following Items layout

 <StackPanel Orientation="Horizontal">
             <TextBlock x:Name="_price" Text="{Binding StringSpecialOfferPrice,UpdateSourceTrigger=PropertyChanged}" Foreground="{DynamicResource ProductPrice}" Style="{DynamicResource DetailCardTitle}" Margin="5,0,0,0"/>
                <TextBlock Text="X" Style="{DynamicResource DetailCardTitle}" VerticalAlignment="Center" Foreground="{DynamicResource ProductDetailMainText}"  Margin="5,0,10,0"/>
                <TextBox Text="{Binding Quantity,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" Style="{StaticResource RoundedTextBoxStyle}" Background="Transparent" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="20" FontWeight="SemiBold"  Foreground="Black" Width="59" />
            </StackPanel>

What is happening is that when I touch the TextBox it is not receiving the touch or something prevent it so that I am not able to go in edit mode. Clicking with mouse inside works of course.

I am running it under W7 and Framwework 4

Any reason ?

Hi,

How can you use Virtual Keyboard in your WPF application? Do you create a touch screen keyboard by yourself and use Sendkey to the TextBox? Here is a related topic about WPF virtual keyboard. Just for your reference. 

http://www.codeproject.com/KB/WPF/TouchScreenKeyboardWPF.aspx

Also, I did some researches for this issue, please refer to the thread below,

How to make WPF input control show virtual Keyboard when it got focus in touch screen?

Here is a code sample on MSDN about the virtual keyboard,

Have a nice time!

Hello thanks for your reply,

I am not talking about virtual keyboard here, I am talking about the simple fact that if I touch my text box, it does not receive the touch input.

Any idea?

Hi,

Based on your code snippet, I created a WPF project on my side and test it. I removed the style for textbox. Since I did not have the specify style. J

I tested it on a Win8.1 touch device. It works fine. I suggested adding a textbox in the windows. We didn’t set any properties for the textbox, and test it. I am afraid that maybe there are some other properties caused this issue.

If the application run on a touch device, I suggested using Surface SDK control. It is a better choice.
