Find the ScrollViewer which contains a Canvas froom within the Canvas instance



I have a class which extends Canvas in WPF.


Canvas



This class is placed in a ScrollViewer.


ScrollViewer



Without passing a specific reference to the ScrollViewer into the Canvas, I want to find the ScrollViewer which contains the Canvas from within the Canvas itself.


ScrollViewer


Canvas


ScrollViewer


Canvas


Canvas



The Parent property of the class which extends Canvas is null, and every attempt to use the VisualTreeHelper just returns null as well.


Parent


Canvas


null


VisualTreeHelper


null



Is this possible to achieve?



Example Code:



cs -


public class ExtendedCanvas:Canvas {

//I wish to automatically populate this scroll viewer
//reference to the instance of the scrollviwer which contains
//this ExtendedCanvas instance
private ScrollViewer _containingScrollViewer = null;

}



xaml -


<ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" >
<local:ExtendedCanvas x:Name="extendedCanvas" />
</ScrollViewer>





Perhaps the person who downvoted this could suggest what I could add to make this a more acceptable question?

Clash Royale CLAN TAG #URR8PPP Arduino Mega cannot recieve any sketches, stk500_recv() programmer is not responding Yesterday we were trying to update the firmware of our 3D-printer a Tevo Tarantula i3 The printer was running Marlin 3D Printer Firmware. We installed a new module a TL-Touch Sensor, a chinese copy of the Bl-Touch an auto bedleveling touch sensor for a 3D printer. After re-configurating a new version of the firmware for our setup in the Arduino IDE we went on with uploading the sketch to the Arduino Mega that was controling our 3D printer. Before we started uploading we made sure the right COM-port was selected in the Arduino IDE and that also the right type of Arduino was selected. The Arduino Mega 2260. Then we started with compiling the firmware and then uploading it to the Mega, Somewhere in between that moment the IDE freezed and crashed. As a response we removed the USB cable that was connected from the PC uploading the firmware onto the Arduino Mega, (This was a st...

Clash Royale CLAN TAG #URR8PPP C++ virtual function: Base class function is called instead of derived I have following code snippet: using namespace std; class base { public: virtual void print(char a){ std::cout<<" Base "<<std::endl;} }; class derived :public base { public: void print(floata) {std::cout<<" Derived "<<std::endl;} }; int main() { base* d = new derived; d->print(1.5); return 0; } Output is "base" Why output is coming from base function and not from derived one By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to these policies.
