I write a Winform application on Win10 OS using Infragistics4 v15.2. And I have a Touch screen.
But why it does not show the key board when the UltraTextEditor get focus ?
Thank you for contacting Infragistics Developer Support!
This matter has been investigated by our development team with the following information determined. This is a limitation of the DotNet framework for Winforms. MS doesn’t provide a way for this to be handled as there isn’t an API to show the touch keyboard. And in testing the MS DataGridView and editors and the same behavior is see where it does not show the touch keyboard.
Please let me know if you have any further questions concerning this matter.
I'm not sure if this will work, but one thing you could try for UltraTextEditor is to set AlwaysInEditMode to true. When you do that, there will always be a TextBox control on top of the UltraTextEditor, so in theory, that should work.
The down side is that you will lose the ability to show certain appearances like gradients or hatches on the UltraTextEditor's background - which is pretty uncommon, anyway.
