我正在开发一个使用 gridview 的 rowupdating 事件的应用程序。我在列中使用 templatefield，因此无法从 gridview 中的文本框获取新值。我如何从文本框中获取新值。以下是我在 rowupdating 中的代码：
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");
}
我想从这些文本框中获取新值，但它总是给我旧值。是的，e.Newvalues 没有给我任何东西。它总是空的。这是我的 gridview 设计的一小段摘录：

谁能告诉我如何从这些文本框中获取新值？
