WPF棱镜自定义弹出窗口未调整为内容大小

Question

I was following this example on how to create and raise custom popup(so i won't add code because of its basically a clone of that example)

The only thing i changes is i added a TextBox

<TextBox Text="{Binding Count}"  />

so i can control the amount of asterisk in the Content of the popup

Basically, I have 2 problems:

• The first one is that the title is cut off (this is with 1 asterisk)

• And the second one is that if i change the content and raise the pop again it does not change the size to fit the content(this is with 50 asterisks)

but i re-start the program and send 50 asterisks it does fit to fill all those asterisks

Is there any way to achieve this besides measuring the text width

Answer 1

I have the same problem. The prism popup-window, once created to contentsize, does not resize when content changes. I am sure that I have all done everything correct with respect to: BindableBase inheritence, and SetProperty calls. But once created (and the window gets created once) no resizing takes place.

I have no solution (other than take over the calculation of the window-size). What I need is a call to force the popup window to (re)resize to new content, somehow.
