Autoscroll Doesn't work in Child UserControl
I have a UserControl Parent
that contains Child
controls. I would like my Parent
control to Autoscroll when it is too small for its Child
. To get Autoscroll, I've set AutoScroll to True in my Parent
, and ensured that the Child
is large enough that I can resize the Parent
to be smaller than it. My Parent
is contained inside a Form
and is anchored to all four edges. The problem is that I cannot seem to get the scrollbars to appear during runtime.
I cannot display a control without a form, of course, unless it's in Designer. In Visual Studio 2008 Designer, the Parent
Autoscrolls perfectly: I can resize the control, and whenever its Child
is partially hidden by the edge开发者_如何学编程 of Parent
, the scrollbars appear. However, when viewing the control in either the Form
's designer or during runtime, the scrollbars do not appear, no matter how I resize the Parent
.
This seems like a bug, but feels more like I'm missing something obvious. Something about being a child of the Form
seems to be inhibiting the AutoScroll.
Try setting dock=none. There appears to be an issue with docking and scroll bars. In my own tests with AutoScroll=true: if Dock=Fill then no scrollbars, if Dock=Top then vertical scrollbar, if Dock=Left then horizontal scrollbar, if Dock=None then both scrollbars.
In the end I set Dock=None for my user controls and scrollbars appeared as expected.
Have you tried placing a Panel docked inside your parent control with your user control inside the Panel?
I had the similar issue.... with my child controls to be created dynamically and then to enable the parent for autoscroll option.
The issue was because i had docked the child panel to left. When we dont dock then parent was working successfully...
