rowupdating沒有給出新的值

我正在使用gridview的rowupdating事件的應用程序。我在我的列中使用templatefield，所以我無法從我在gridview中的textboxws中獲取新值。我怎樣才能從文本框中獲得新的值。以下是我的代碼rowupdating：rowupdating沒有給出新的值

protected void gviewTemplate_RowUpdating(object sender, GridViewUpdateEventArgs e) 
{ 
    gviewTemplate.EditIndex = -1; 
    string rowNum = ViewState["ID"].ToString(); 
    Label lbl2 = (Label)gviewTemplate.Rows[e.RowIndex].FindControl("lblTemplateName"); 
    Label lbl1 = (Label)gviewTemplate.Rows[e.RowIndex].FindControl("lblUploaded"); 

    TextBox txtTempName = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtTemplateName"); 
    TextBox txtHeading = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtHeading"); 
    TextBox txtCoupon = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtCouponText"); 
    TextBox txtBrand = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtBrandName"); 
    TextBox txtSearchText = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtSearch"); 
    TextBox txtDiscount = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtDiscount"); 
    TextBox txtStartDt = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtStartDt"); 
}

我想從這些文本框中獲取新的值，但它總是給我舊值。是的，e.Newvalues沒有給我任何東西。它總是空的。這是小摘自我的gridview的設計：

誰能告訴我如何從這些文本框的新值？
