I am having a problem with WPF text box , its not allowing record space when pressing space bar on key board

Sgcino Ngema 0

When adding some text on text box in a wpf application its not arecording the space.

it's only allowing it if i type the text as one string and use the back keys to go back to to where i want to record the space.

Not sure what is the cause and solution to this

Does this happen in any new simplest projects?

Also check if the space works in Notepad and other programs.

I am developer , and i am maintaining a WPF application.

Recently we upgraded our .Net to 4.7.2 , below is an xaml file code which is now allowing the space bar when capturing notes

Maybe there is an issue with binding. What is strNotes?

If the program contains other windows that use the third-party controls, did you observe the issue in other places?

Please provide the steps needed to replicate your issue. It is unclear whether you're doing this as the end user, inserting data programmatically, getting data out of the control programmatically, etc. Please provide as much detail as possible.

Also please identify what version of the framework you're using (NET 4.8, NET 8, etc) and if you're using anything that may interfere with the control such as third party controls. Also let us know if you have handlers or other code that may intercept the text box.

Hi,@Sgcino Ngema. Welcome to Microsoft Q&A. Could you please show your code-behind code to reproduce your issue without private information so I can reproduce the issue? Can you specify which textbox the error occurs in? And what are the steps to reproduce the issue?
