What a “feature” 🙁
In one of the LOB apps I’m building, I set some of the text boxes to enabled, read-only and no tab stop. Then I needed top copy the content of one of these text boxes into the clipboard. It was not possible! Because you cannot mark the content of the box!
As soon as I removed the IsTabStop="false"
property from the style, Copy&Paste was working again. For the price that I had to define the tab order manually. And in case the sequence of the controls changes, I have to take care to reset the TabIndex
property of each control.
