EOD... i found the solution....

I should assume column name to bind drdList.DataTextField = "Prod_name";

My code is...

ONPAGE_LOAD()

{
.....
Grid_Purchase.DataSource = dt; //dt contains empty rows
            Grid_Purchase.DataBind();
            DataTable myDatatable1 = new DataTable();
            myDatatable1 =  SQLobj.SQL_Adapter("select Prod_name from ProductDetails");
            DropDownList drdList;
            DataRow dr;
            dr = myDatatable1.NewRow();
            dr["Prod_name"] = "-Select-";
            myDatatable1.Rows.InsertAt(dr, 0);
            foreach (GridViewRow grdRow in Grid_Purchase.Rows)
            {
                drdList = (DropDownList)(Grid_Purchase.Rows[grdRow.RowIndex].Cells[1].FindControl("txt_grd_ProdName"));
                drdList.DataSource = myDatatable1;
                drdList.DataTextField = "Prod_name";   
                drdList.DataBind();
            }
            
}

My aspx ,page

XML

<asp:TemplateField HeaderText="Products">
                 <ItemTemplate>
                       <asp:DropDownList ID="txt_grd_ProdName" runat="server" Width="95px" AutoPostBack="True" onselectedindexchanged="txt_grd_ProdName_SelectedIndexChanged"><asp:ListItem>-Select-</asp:ListItem> </asp:DropDownList>
                  </ItemTemplate>
                <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                <FooterTemplate>
                    <asp:DropDownList ID="Foot_Txt2" runat="server" Width="95px" AutoPostBack="True" ></asp:DropDownList>
                </FooterTemplate>
                  </asp:TemplateField>
