Yes you can. Follow these steps.

1).Create a query which fetches the fname from details table.
2).Call cmd.ExecuteReader with this query.
3).Now bind the dropdownlist from the datareade.

For this step you can use the following code.

<dropdownlist>.DataSource = <datareader>
<dropdownlist>.DataBind()

If Not Page.IsPostBack Then
Dim conn As SqlConnection
Dim cmd As SqlCommand
Dim dr As SqlDataReader
Dim str1 As String
Dim strcon As String

str1 = "select * from details"
strcon = "Data Source=PC-1;Initial Catalog=jay;user id=;pwd=;Trusted_Connection=yes"
conn = New SqlConnection(strcon)
conn.Open()
cmd = New SqlCommand(str1, conn)

dr = cmd.ExecuteReader()
DropDownList1.DataSource = dr
DropDownList1.DataValueField = "srno"
DropDownList1.DataTextField = "fname"
DropDownList1.DataBind()
______________________________________
it gives an error...any suggestions,,i have written ths code on page load,,,reply asap

Well, your sql query is fetching all columns from the table and your dropdownlist cannot be bound to such a recordset.
What you need to do is modify your sql query to fetch only fname as in

select fname from details

            dbadap.Fill(ds, "details")
            DropDownList1.DataSource = ds.Tables("details").DefaultView
            DropDownList1.DataBind()
            DropDownList1.SelectedValue = ""
            MsgBox(DropDownList1.SelectedValue)
            DropDownList1.DataValueField = "srno"
            DropDownList1.DataTextField = "fname"

dude is there ne way we can get the result by editing the line

DropDownList1.DataSource = dr

i dont want to use datasource at all,is it possible,,,,reply asasp

Well one way is to loop through the datareader and get the values in each row and add it to dropdownlist.
This involves the following steps.

While end of datareader
create list item instance
add fname of row(i) to listitem text
add srid of row(i) to listitem value
add listitem to dropdownlist
end while

If rd.HasRows Then
Do While rd.Read
	
        li = New ListItem
        li.Text= rd.Item("fname")
        li.Value = rd.Item("srid")
        <dropdownlist>.Items.Add(li)

This is a great sample. I've been searching google for an hour to find a good sample for creating a sqldatasource in a class. Thank you!!
