When a CommandColumn cell is focused and we try to focus an external control, the RadGridView can't lose focus. The internal code will force the control to focus the CommandColumn cell again.

Workaround:

- Use RadForm it explicitly handles the controls scaling. 
- Make sure that the following of the user controls are set like this:

this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;
