How to collapse databound TextBlock
Hello,
I'd like to set the "Visibility" property of a databound TextBlock based on whether there is any content or not. In the following example, there is an empty XML element<Department>, so the TextBlock in row 2 should be collapsed. What is the simplest way to do this? What is the simplest way to do this?
Thanks,
Adrian
