To fix the issue you can do You are missing to Check for Postback as well as Your are missing DataTextField and DataValueField
code :
protected void Page_Load(object sender, EventArgs e)
    {

if(!Page.IsPostBack)
{

string str = "Provider=Microsoft.ACE.OleDB.12.0; Data Source=C:\\Users\\Dima\\Documents\\Visual Studio 2013\\Projects\\networklab1\\bin\\weblabdb.accdb";
        OleDbConnection db = new OleDbConnection(str);
        db.Open();
        string st = "select areaName from area;";
        OleDbCommand dbc = new OleDbCommand(st, db);
        OleDbDataReader read = dbc.ExecuteReader();

        DropDownList1.DataSource = read;
        DropDownList1.DataTextField="areaName";       //missing this
        DropDownList1.DataValueField="areaName";        //missing this
        DropDownList1.DataBind();
        read.Close();
        db.Close();

}

    }

wish of those help I found an error ! Access VBA code is ok but problem was with content of Document.dotx. I wrote in my post that I have set dot separator in regional settings but in Word bookmark "NR" I saw coma. That was issue. I changed bookmark properties (number format from 0,00 to 0.00) and everythings work great. I'm sorry that I answered myself to my question but I hope this can help others to find a solution to the problem.

around this issue You can change your LINQ query to the following which will return all the nodes under root and return new items with the value/text pairs that you are trying to bind to.

I wish this help you If I am understanding you correctly; ddlvillage data bind happens at page load when the method ddltaluka_selectedIndexChanged is called, you try to bind new data do it but it goes back to the original ddlVillage list?
If this is the case you need to only do the initial databind for ddlVillage on the initial page load and not each post back
