MinimumSize property does not work for MdiChild forms. It should work for all other types of forms. Microsoft is aware of this bug and have stated that it will be fixed in a future release. One work around developers have used is to check if the Form has been resized to a smaller size than MinimumSize (and resizing it back) in the Resize event handler for the child form.

private void ChildFrm_Resize(object sender, System.EventArgs e)
    {
        // Please modify code according to your requirement
        int CurrHt=this.Height;
        int MinHt=this.MinimumSize.Height;
        if( CurrHt <= MinHt)
        {
            CurrHt = MinHt;
            return;
        }
    }
