BUG: Using WM_SETREDRAW w/ TreeView Control Gives Odd Results (130611)
The information in this article applies to:
- Microsoft Platform Software Development Kit (SDK) 1.0
This article was previously published under Q130611 SYMPTOMS
If a program uses the WM_SETREDRAW message to turn off updating of a
TreeView control before adding items, the TreeView control can behave
strangely.
For example, if the item being added to the control uses the TVI_FIRST
style to insert it to the top of the tree and the top of the tree is
scrolled above the top of the visible window, it may be impossible to bring
the item into view.
Another possible symptom is that the TreeView control doesn't repaint
itself at all. These problems occur only if the program has used the
WM_SETREDRAW message to turn off updating the TreeView control.
RESOLUTION
Don't use the WM_SETREDRAW message with the TreeView control while adding
items to the control.
