hi,
try below code
int top = 50;
                int left = 50;
                for (int i = 1; i<=count;i++)
                {
                    Button button = new Button();
                    button.Left = left;
                    button.Top = top;
                    button.Text = ItemTable.Rows[i-1][0].ToString();
                    this.Controls.Add(button);
                    if (i %5 == 0)
                    {
                        left = 50;
                        top += button.Height + 2;
                    }
                    else
                    {
                        left += button.Width + 2;
                    }
                }

and before
button.Text = ItemTable.Rows[i][0].ToString();
now
button.Text = ItemTable.Rows[i-1][0].ToString();

hi,
check for loop before it is i=0 andi< count but now as below
for (int i = 1; i<=count;i++)

and before
button.Text = ItemTable.Rows[i][0].ToString();
now
button.Text = ItemTable.Rows[i-1][0].ToString();

Result is
1. row 1 button is on top (First table value)
2. row 5 buttons(second table value, third table value....etc)
3. row 5 buttons
4. row 5 buttons
5. row 5 buttons
6. row 5 buttons
7. row 3 buttons

Why is first button allone?
