WPF Textbox not accepting keyboard inputs

Hi,

We are experiencing some issues with our WPF controls which are included in an ADXExcelTaskPane.

On some user machines, every time they select a Textbox control, it appears to activate, the cursor flashes as though it is ready to start typing, but all keyboard inputs have no effect. We can right-click on the control with the mouse and perform an action such as 'paste' which works, but only using the mouse.

This behaviour occurs 100% of the time on affected machines. We have been unable to find any common attributes between machines affected by the behaviour.

Note, the focus does not at any stage revert to Excel, which rules out some related problems we have seen documented.

Also, we use some native WPF dialogs in Excel (not hosted in a windows form window), and textboxs within these do not experience the problem. It is only affecting textbox controls hosted in the ADXExcelTaskPane.

Are you able to advise if you have encountered this behaviour and what we might do to fix it?

Hi Sean,

Thank you for the detailed description.

In version 9.4.4644 we have fixed the following issue:
Keyboard issues with Advanced Outlook regions and Advanced Office task panes in Windows 10 Update 1903.

Please let me know what Add-in Express version you use.

The issue cropped up a few weeks ago in production with an older version, however our newer versions of the add-in, built with ADX 9.4.4644 continue to have the issue.

Hello Sean,

I have just tested the WPF TextBox typing with 9.4.4644 version of ADX, it works fine. Please make sure you use this version. You can check it by using the following code:

typeof(AddinExpress.XL.ADXExcelTaskPane).Assembly.GetName().ToString()
Regards,

Yes, it appears our build server has an old version... that solves it! Many thanks for your help
