Question

Position and border colour of borderless form

rahul kumar 605

Hi , I had created a form which should be used for the confirmation when the user presses enter . The problem is I want this form to have the black borders on all sides and that black border should be visible within the Panel1 area (not outside it ) . Also it should be positioned to the right bottom side of the panel .

sorry for late response . Regarding your answer , i found out that the border on the bottom and right side is not showing . I am pasting here the full code .

The form which has a black border on all sides (your answer) . this form I have used as base form

 public partial class blackborder_lightform : Form
    {
        public blackborder_lightform()
        {
            InitializeComponent();
        }
        protected override void OnPaint(PaintEventArgs e)
        {            
            Rectangle borderRect = new Rectangle(0, 0, Width, Height);
            ControlPaint.DrawBorder(e.Graphics, borderRect, Color.Black, 2, ButtonBorderStyle.Solid, Color.Black, 2, ButtonBorderStyle.Solid, Color.Black, 2, ButtonBorderStyle.Solid, Color.Black, 2, ButtonBorderStyle.Solid);
        }

now there is another form which inherits from the above blackborder_lightform form so that by default it will have a black border too

    public partial class StockitemCDA : blackborder_lightform
    {
        public StockitemCDA()
        {
            InitializeComponent();
        }

        private void StockitemCDA_Load(object sender, EventArgs e)
        {  // add all controls having type starting from customtextbox bind to same textbox 
            Controls
            .OfType<customtextbox>()
            .ToList()
            .ForEach(b => { b.TriggerEvent += OnTriggerEvent; });
        }

        private void OnTriggerEvent(bool last, string name)

        {
            if (last)
            {
                Confirmform messForm = new Confirmform();

                Point PositionX = this.PointToScreen(Point.Empty);
                int RightScreenX = PositionX.X + this.Width;

                Point PositionY = this.PointToScreen(Point.Empty);
                int DownScreenY = PositionY.Y + this.Height;

                messForm.StartPosition = FormStartPosition.Manual;
                messForm.Location = new Point(RightScreenX - messForm.Width, DownScreenY - messForm.Height);
                messForm.ShowInTaskbar = false;
                messForm.ShowDialog();

            }
        }

As you can see i am opening a yet another form inside this StockitemCDA form which is called confirmform . now this confirmform also inherits from blackborderlight form . also this confirmform is opening in right down side (thanks to you) . but the problem is the border is not visible in the right and bottom side . pls suggest

  public partial class Confirmform : blackborder_lightform
    {

This is because the colors and position of the two borders overlap.

Tested contrasting colors like red and avoid overlapping borders.
messForm.Location = new Point(RightScreenX - messForm.Width-2, DownScreenY - messForm.Height-2);

Hi,

To create a black border:

In order to make the effect more obvious, I set a width of 10.

form2:

        protected override void OnPaint(PaintEventArgs e)
        {
            Rectangle borderRect = new Rectangle(0, 0, Width, Height);
            ControlPaint.DrawBorder(e.Graphics, borderRect, Color.Black, 10, ButtonBorderStyle.Solid, Color.Black, 10, ButtonBorderStyle.Solid, Color.Black, 10, ButtonBorderStyle.Solid, Color.Black, 10, ButtonBorderStyle.Solid);
        }

be positioned to the right bottom side of the panel

Create form2 in form1.

Gets the position of the panel relative to the screen and minus the length of the message form.

           Form2 messForm = new Form2();

            Point panelPositionX = panel1.PointToScreen(Point.Empty);
            int panelRightScreenX = panelPositionX.X + panel1.Width;

            Point panelPositionY = panel1.PointToScreen(Point.Empty);
            int panelDownScreenY = panelPositionY.Y + panel1.Height;
           
            messForm.StartPosition = FormStartPosition.Manual;
            messForm.Location =new Point(panelRightScreenX - messForm.Width, panelDownScreenY - messForm.Height);
            messForm.ShowDialog();

enter image description here
