i try a Drag/Drop scenario.
I have noticed that after first left mouse click (for example on a button), Wisej.Web.Control.MouseButtons is always MouseButtons.Left.
But, if no key is pressed, it should be MouseButton.None ?!
No sample needed, it’s very simple.
System.Windows.Forms.Control.MouseButton : Gets a value indicating which of the mouse buttons is in a pressed state.
Your Wisej.Web.Control.MouseButton save the last button, once you click, the value remains permanent.
The value must be chaged to MouseButtons.None, when the mouse button is released.
