Rounded button?

Existing code is ok

private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'bssDataSet.roba_usluge' table. You can move, or remove it, as needed.
this.roba_uslugeTableAdapter.Fill(this.bssDataSet.roba_usluge);
SqlConnection con = new SqlConnection("Data Source=.\\SQLEXPRESS;Initial Catalog=bss;Integrated Security=True");
SqlCommand cmd = new SqlCommand("SELECT ime+'-'+cijena_sa_porezom, data FROM roba_usluge", con);
// Getting all the data to ItemTable
var da = new SqlDataAdapter(cmd);
var ItemTable = new DataTable();
da.Fill(ItemTable);
con.Open();
Int32 count = ItemTable.Rows.Count;
con.Close();
int top = 50;
int left = 50;
for (int i = 1; i <= count; i++)
// for (int i = 0; i < count; i++)
{
Button button = new Button();
button.Size = new Size(128,128);
button.BackColor = Color.Transparent;
//button.FlatStyle = FlatStyle.Flat;
button.FlatAppearance.BorderSize = 0;
button.Font = new System.Drawing.Font("Trebuchet MS", 10);
button.TextAlign = ContentAlignment.TopCenter;
button.BackgroundImageLayout = ImageLayout.Zoom;
button.Left = left;
button.Top = top;
button.Text = ItemTable.Rows[i - 1][0].ToString();
if (ItemTable.Rows[i - 1][1] != null)
{
try
{
byte[] _byte = (byte[])ItemTable.Rows[i - 1][1];
MemoryStream ms = new MemoryStream(_byte);
button.BackgroundImage = System.Drawing.Image.FromStream(ms);
}
catch { }
}
button.Click += new EventHandler(this.btn_Click);
this.Controls.Add(button);
if (i % 5 == 0)
{
left = 50;
top += button.Height + 2;
}
else
{
left += button.Width + 2;
}
}
}

I think in rectangle radius will not work
Goran Bibic8y ago
Solution work
GraphicsPath grPath = new GraphicsPath();
Rectangle rect = new Rectangle(0, 0, 128, 128);
grPath.AddRectangle(rect);
this.Region = new System.Drawing.Region(grPath);
base.OnPaint(e);
How to setup corner radius?
Goran Bibic8y ago
Like this?
But if I put 0,0,0,0 its empty

128,128,128,128 empty...

On this code are just small icons
                GraphicsPath grPath = new GraphicsPath();
                //grPath.AddEllipse(0, 0, ClientSize.Width, ClientSize.Height);
                Rectangle rect = new Rectangle(50, 50, 50, 50);
                grPath.AddRectangle(rect);
                this.Region = new System.Drawing.Region(grPath);
                base.OnPaint(e);

I try this
grPath.AddRectang(0, 0, ClientSize.Width, ClientSize.Height);
But not...
GraphicsPath does not contain definiton for AddRectang and no extension method AddRectang aceept first argumne type GraphicsPath coudn not be found

I think its problem inside ( )

hi add this Class
public class RoundButton : Button
    {
        protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
        {
            GraphicsPath grPath = new GraphicsPath();
            grPath.AddEllipse(0, 0, ClientSize.Width, ClientSize.Height);
            this.Region = new System.Drawing.Region(grPath);
            base.OnPaint(e);
        }
    }
then
replace in your code in line no 26
this
Button button = new Button();
with
RoundButton button = new RoundButton();
