问题 In WPF, I want to add a userControl in/over titlebar in Window, like this: The Red part is that UserControl, and the Green part is titlebar. Now I hope to get some suggestions from you.

问题 I want to set the backgroun color for a GridViewColumn that is databound inside of a listview in WPF. I'm not sure how to ask this question being fairly new to WPF, otherwise I wouldn't have bothered all of you.

In this case, I have, well, a "CaseDetail" object, that when there are internal notes "IsInternalNote" I want the color of the row to change. How can I pull this off in WPF? What I

问题 Lets assume I have a very simple application that only has 8 inputs grouped in 2 Panels (4 inputs | 4 inputs - see picture bellow) and based on these, I plot a small plot (easy peasy). The problem that I face is that I want to have the labels only for the first panel, and on the left of the textInput box. e.g. (Please excuse my sloppy image editing!) Any suggestion?
