WPF graph controls selection

[eugenem]

Is it possible now to know when user clicks at marker or annotation? It wasn't working in v.2012.

Hi Eugenem,

Could you clarify what you mean by marker or annotation?  Are you just trying to register a user click event?

[eugenem]

sorry, i mean cursor of course

look at the picture

and yes, i need to know when user click at the cursor

currently i can only get event when user moves the cursor...

Hi Eugenem,

I think what you want is to use the User32.DLL to set and get the cursor position.  It wouldn't be so much on the Measurement Studio side of things but rather just calling the Win32.GetCursorPos().  Here is a link on stackoverflow that goes through programmatically getting and setting position of the cursor and also programatically clicking.

As mentioned in the how to get click on cursor or annotation question, only the GetChildrenAtPoint issue was fixed in Measurement Studio 2013, which is the latest release available at this time. You can now hit test against target, line, and crosshair parts of graph cursors and annotations when handling preview mouse events in the graph, but parts like labels will not return a hit test result.

Hi, Paul! Glad you're back :). I'll check this out...

Just wanted to let you know this issue (#406324) was fixed in the Measurement Studio 2015 release.
