take a dropdown list box
drag it in asp.net webpage i.e aspx page or design page

page load event write

load_dropdown()

then

VB

Protected Sub load_dropdown()
        Dim sqlselect As String
        
            sqlselect = " SELECT columan_name FROM table_name "
            ds = Utility.ExecuteDataset(ConnectionString, CommandType.Text, sqlselect)
            ddlblockperiod.DataSource = ds
            ddlblockperiod.DataValueField = column_id;
            ddlblockperiod.DataTextField = column_name;
            ddlblockperiod.DataBind()
            ds.Dispose()

End Sub

Var id=(from a in linq_obj.table name
Select new
{
Intglcode=a.intglcode,
columnname =a.columnname
}).Tolist();
ddlblockperiod.Datasource=id;
ddlblockperiod.DataValueField = column_id;
ddlblockperiod.DataTextField = column_name;
ddlblockperiod.Databind();

DOne :)

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DataClassesDataContext countries = new DataClassesDataContext();
            DropDownList1.DataSource = countries.SelectCountries();
            DropDownList1.DataTextField = "CountryName";
            DropDownList1.DataBind();
        }
    }

As

DataClassesDataContext

>>> is a Link to SQL Classes
&

SelectCountries

>>>> is a class in

DataClassesDataContext

, that Select all countries from countries table
&

CountryName

>>> is the selected column from countries table

Thanks all for answers :)
