Same with maxWidth if doing a top-down or bottom-up flow. Otherwise, it'll just keep setting the row height to the largest control already encountered in the other rows. MaxHeight needs to be reset to 0 after wrapping to the next row. The comparison to >= parentWidth should be >, as equality would still allow the child control to fit (I think!). The GridLayout option isn't implemented, so I removed it.
This causes problems in calculating whether a control can fit, both when the FlowLayoutPanel is displaying a scrollbar and in cases when the panel isn't taking up the whole width of the parent control.ĬlientSize.Width should really be used instead of just the Control's width, as this gives the true usable width rather than including scrollbar width and borders.
#FLOWLAYOUT OPTIONS NOT AVAILABLE WITH PANEL OBJECT CODE#
I'm not sure why the code checks to see if a parent to the FlowLayoutPanel exists and uses its width instead. I noticed that when resizing the demo form, it determines whether the wrapped control can be redrawn on the previous row based on the size of the last control drawn, rather than the size of the actual next control. The FlowLayoutPanel is a small application with a custom control ( FlowLayoutPanel.cs) that extends and overrides:Ī few things I had to fix to actually use the control:
Since I've posted this, I've enhanced it a little to include a LayoutStyle property that takes an enum for LayoutStyles.FlowLayout or LayoutStyles.GridLayout. I'm currently implementing a thumbnail view and was anguished over the fact that there was no FlowLayout option for WinForms, and having Googled for FlowLayout controls and seeing a remarkable dearth of them, I decided to write my own and share it for general consumption. While many of us don't mind absolute positioning, it can get to be a bear (or at the very least annoying) when you want to add controls dynamically but don't want to worry about or.
The FlowLayout option for laying out your controls has been missing from. With the next Visual Studio being in Beta 2 and the FlowLayout supposedly making its comeback in said revision, this could very well be a day late and a dollar short, but I had need of it and thought I would share it anyway.
