Displaying the WPF Canvas just below the HyperLink

Question

0.00/5 (No votes)

See more:

I have a Canvas (which acts like a mini - details window) and I have a StackPanel which has some HyperLink elements in it. Each HyperLink is positioned differently and is dynamically added to the Canvas. I show the Canvas (the mini details window) as soon as the user clicks on it.

Now I wrote the logic to show the Canvas on the location (getting the X, Y co-ordinates by calling the MouseEventArgs.GetPosition(null) method). I then set the margin of the Canvas according to the X, Y co-ordinates. However. It is not showing up as expected. I want the Canvas to be shown exactly below the link. Can anybody help me out?

Solution 1

When you get the coordinates of your Mouse on click, grab the label control that exists in that position. Then you just have to offset your panel based on the labels position instead of the mouse position.

Here is a thread on how to achieve that: WPF Get Elements under mouse[^]

I understood your solution and when I tried accessing the margin properties of the label, I get a zero margin on all sides. Please guide me.

Margin is likely going to be 0 on a label. You need to use the position properties(ie. Left, Right, Top, Bottom) to get orientation values.

Thanks a lot for your reply :)
I am newbie to WPF. Please guide me to access the properties you mentioned, Left, Right, Top, Bottom as I am unable to get them (Label.Right etc).
