I have an UltraTree placed within UltraExplorerBarContainerControl that is one of the items on UltraExplorerBar navigation control docked to the left side of the screen. This tree has numerous nodes and if expanded UltraExplorerBar vertical scroll bar appears as it should. The problem is whilst the UltraExplorerBar handles MouseWheel event when the mouse is over the expanded tree (takes most of the vertical space) MouseWheel Up or Down has no effect - the scroll does not work. The MouseWheel event within the tree is firing but since the control is hosted within the container control no scrolling occurs.
To resolve this issue I am trying to initiate programmatic scrolling of the UltraExplorerBar on tree_MouseWheel() event however I noticed that UltraWinExplorerBar.UltraExplorerBarAction enumerator supports only ScrollPageUp and ScrollPageDown which scrolls an entire page at a time (similar to what happens when user clicks on the scrollbar) rather than actual scrolling. Do you have any suggestions on how this issue can be resolved?
I am using UltraWinExplorerBar 9.2.20092.2042 and UltraWinTree 9.2.20092.2042. Thanks.
Hello,
What style do you have the UltraExplorerBar set to? I made a small sample and tried with several different styles and I found that with some styles, you have to click on the control in order for the mouse wheel to scroll the tree. The only code I wrote was to populate the UltraTree with 100 nodes.
Also, I made my sample using 10.2.20102.2058. If clicking on the UltraTree doesn't allow scrolling, try it with a newer version of our product.
The style is UltraExplorerBarStyle.VisualStudio2005Toolbox. Clicking on tree first does not seem to help and even if it worked that behavior would be inconsistent as the rest of the bar can be scrolled by the mouse wheel just while hovering over the bar area. Since it does not seem to work correctly even in version 10 should that be considered an enhancement request?
