SplitterDistance changes as size of control changes

I have a SplitContainer control on my form. It's docked to the form. And I set the SplitterDistance from code when the form loads.

This works fine except that the SplitterDistance changes when I resize the form. For example, when I make the form wider, the SplitterDistances seems to become larger so that it retains about the same percentage of width of the parent.

I don't want this. I want the distance between the splitter bar and the left of the control to stay the same as the window is resized. However, I don't want to set IsSplitterFixed = true because I still want to allow the user to change it.

Solution

  • You can set FixedPanel property to the panel which you want to remain the same size when the container is resized. You can do it using designer, or using code:

    this.splitContainer1.FixedPanel = System.Windows.Forms.FixedPanel.Panel1;
