Free-form input

Postby krylon » Tue Nov 26, 2019 1:43 am

Hello everyone,

Is it possible allow users to do "free-form" input on mobile/touch devices? Our use case would be users entering their signature.

You can do that in may ways, but some manual coding is required.

One way is to register the PointerPressed, PointerMove, and PointerReleased events and add segments to a Path control to draw. You can re-use some of the code from the "Drag and Drop" demo in the Showcase app, located at: ... L_Features

Another way is to use the native HTML <canvas> control in conjuction with the LineElement class, as documented at: ... anvas.aspx
