I had this bug, wherein, the font displayed by the controls of a Child Form are not working. The controls were supposed to inherit the font of the Child Form since their Font properties are not set to anything but default.
Here's how I encountered the bug:
Firstly, I had the Font property of the Child Form set programmatically to some custom font that works. I haven't tried setting the Font property of the Child Form directly in the designer, but it should be the same as setting it via code. I made all the DockPanel's DockWindows' and FloatWindows' Font to the custom font.
Next, it was shown in the DockPanel. The fonts were not applied on form load.
Then, I tried undocking a Child Form. Still, the font was not rendered on that Child Form.
Lastly, I docked that Child Form again. This time, the font was rendered as it should be.
If I undocked the Child Form, the font will not display correctly, and if it is docked back, it will.
Hi, if possible, please write a small sample and share with us via DropBox. Thanks.
Closing out as not reproducible.
