        drToGrid["Employee"] = ddlEmployeeID.SelectedItem;
        drToGrid["Location"] = ddlLocationID.SelectedItem;
        drToGrid["Supplier"] = ddlSupplierID.SelectedItem;
        drToGrid["IssuedDate"] = txtIssuedReceivedDate.Text.Trim();

}
  protected void LinkAssetDelete_OnClick(object sender, EventArgs args)
    {
        LinkButton link = (LinkButton)sender;
        GridViewRow gv = (GridViewRow)(link.Parent.Parent);
        DataSet ds = new DataSet();
        DataTable dtToGrid = (DataTable)Session["dtToGrid"];
        DataTable dt = ds.Tables["tToGrid"];
