Don't ever search your control. Search your database.

Ya.. I do that and write a piece of code...
if (ddliname.SelectedItem.Text.ToString())
{
cmd = new SqlCommand("Select p_name from Quote_pro_details where p_name='" + ddliname.SelectedItem.Text + "'", con);
cmd.CommandType = CommandType.Text;
da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
string i = ds.Tables[0].Rows[0][0].ToString();
if (i!=0)
{
lblmsg3.Visible = true;
lblmsg3.ForeColor = System.Drawing.Color.Red;
lblmsg3.Text = "Product already entered";
}
}

I dont know how to implement it in if condition.... i am getting error..........

Tell us the error if you want help. However, I don't think this is what you want. I suspect you get an error when there's no data returned, because the NUMBER of rows is 0, there's no 0 returned. Use select count(*) to get the number or fix your code to check if ds.Tables[0].Rows.Count is 0.
