{
DataTable dt = new DataTable();

DataColumn[] columns = { new DataColumn("Country", System.Type.GetType("System.String")), new DataColumn("Language", System.Type.GetType("System.String")), new DataColumn("Description", System.Type.GetType("System.String")) };

        dt.Columns.AddRange(columns);
        DataRow dr;

        dr = dt.NewRow();
        dr[0] = ddlCountry.SelectedValue;
        dr[1] = ddlLanguage.SelectedValue;
        dr[2] = txtDescription.Text;

C#

protected void lnkbtnAddRow_Click(object sender, EventArgs e)
{
if(Session["Data"]==null)
{
DataTable dt = new DataTable();
 
DataColumn[] columns = { new DataColumn("Country", System.Type.GetType("System.String")), new DataColumn("Language", System.Type.GetType("System.String")), new DataColumn("Description", System.Type.GetType("System.String")) };
dt.Columns.AddRange(columns);
}
else
{
 DataTable dt=(DataTable)Session["Data"];
}
 
        
        DataRow dr;
 
        dr = dt.NewRow();
        dr[0] = ddlCountry.SelectedValue;
        dr[1] = ddlLanguage.SelectedValue;
        dr[2] = txtDescription.Text;
        dt.Rows.Add(dr);
        Session["Data"]=dt;
        GVaddrow.DataSource = dt;
        GVaddrow.DataBind();
}

Try this...It should work...
