How to avoid the sizing issues in WinForms GroupBar?

Avoid sizing issues

When adding the UserControl to the GroupBarItem’s Client area, the UserControl is added as a child control of the GroupBar and sizing issue may occur in UserControl. This behavior with GroupBar occurs due to the AutoScaleMode property. When you set the AutoScaleMode property to “Font”, the font of UserControl uses the font of the parent.

The following settings can be used to avoid this issue:

1. Set AutoScaleMode property to “Inherit” to correct the scaling of the UserControl.
2. Set the new Font for the UserControl after setting AutoScaleMode property.

The following code example is to demonstrate the same.

C#

//To set AutoScaleMode as Inherit.
this.textBoxExt1.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Inherit;
//To set the font for the UserControl.
this.textBoxExt1.Font = new Font("Segoe UI", 10);

VB

'To set AutoScaleMode as Inherit.
Me.textBoxExt1.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Inherit
'To set the font for the UserControl.
Me.textBoxExt1.Font = New Font("Segoe UI", 10)
