Draw Line To Listview Control
Aug 19 2011 1:47 PM
I am trying here to draw a line to listview control but fails to do so. my complete demonstration is below:
public partial class Form1 : Form
{
private ListView mylst;
public Form1()
{
InitializeComponent();
MyListView1 lst = new MyListView1();
mylst = lst;
this.Controls.Add(mylst);
}
private void Form1_Load(object sender, EventArgs e)
{
mylst.Dock = DockStyle.Fill;
listviewbind();
}
public class MyListView1 : ListView
{
protected override void OnPaint(PaintEventArgs e)
{
Pen blackPen = new Pen(Color.Black, 3);
// Create points that define line.
Point point1 = new Point(0, 0);
Point point2 = new Point(10, 0);
// Draw line to screen.
e.Graphics.DrawLine(blackPen, point1, point2);
base.OnPaint(e);
}
}
public void listviewbind()
{
mylst.View = View.Details;
mylst.Columns.Add("name");
mylst.Columns.Add("amount");
string connstr = "server=.;initial catalog=maa;uid=mah;pwd=mah";
SqlConnection con = new SqlConnection(connstr);
con.Open();
string sql = "select name,amount from dummy";
SqlDataAdapter dap = new SqlDataAdapter(sql, con);
DataTable ds = new DataTable();
dap.Fill(ds);
for (int i = 0; i < ds.Rows.Count;i++)
{
DataRow dr = ds.Rows[i];
ListViewItem lvi = new ListViewItem(dr["name"].ToString());
lvi.SubItems.Add (dr["amount"].ToString());
mylst.Items.Add(lvi);
}
}
