Scrolling outside the bounds of an UltraScrollBar control
posted

Hi to All.  I am experiencing behaviour in an UltraScrollBar control that I am unable to override given my current level of knowledge.  It occurs when scrolling by dragging the ThumbTrack to either end of the scrollbar's Minimum and Maximum value boundaries.  Once the mouse cursor is moved beyond either end of the control by more one LargeChange amount then ThumbTrack returns to the position at which it was positioned on the scrollbar before the ThumbTrack drag was commenced.  If the left mouse button is then released the control remains at it's original position, however if, while the left mouse button is still depressed, the cursor is moved back to one LargeChange beyond the end of the control the ThumbTrack snaps to the end where you are at.

The behaviour I desire is for that "snap back to its original position" behaviour to not occur and for the ThumbTrack to stay at the end to where it was dragged - unless the mouse button is released when the cursor is located outside of the UltraScrollBar control's boundaries.

Does anyone know of a possible solution to my problem?

    I just tried this out and I see the behavior you are describing. I don't beleive there is any way to turn this off. This is the standard behavior of scrollbars in Windows. I tried the same things with the inbox scrollbar and with some application scrollbars, like hte project windows in Vistual Studio and I get the same results in all cases.
