Question

在下面的代码中，字符串 sFoodFormReceived1 始终获取DateTime.Now的值。我不知道如何使datepicker UI上点击的日期绑定到gridview gvReservationsWithForms中的文本框。

protected void gvReservationsWithForms_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    GridViewRow row = gvReservationsWithForms.Rows[e.RowIndex];
    string sFoodFormReceived1 = ((TextBox)(row.Cells[9].Controls[1])).Text;

    DataTable dt = dsReservationsToBind.Tables[0];


    dt.Rows[gvReservationsWithForms.EditIndex]["FoodFormReceived"] = new DateTime(System.DateTime.Parse(sFoodFormReceived1));
    DataRow dr = dt.Rows[row.DataItemIndex];

    var Reservation = new reservation_RoomReservationTableAdapter();

    Reservation.Update(dr);

    gvReservationsWithForms.EditIndex = -1; 
    gvReservationsWithForms.DataBind();        

}

您可能希望在代码中将文本框设置为datetime.now，而不是在RowEditing上。这样，绑定不会干扰。可能是......

另外，如果你这样做，你可能会获得更好的表现：

$("#<%= gvReservationsWithForms.ClientID %>")
   .find("input[id$='tbFoodFormReceivedEditItemTemplate']").datepicker();

相反，您将输入控件仅限制为gridview，而不是整个页面。

jquery datepicker日期在gridview编辑/更新中没有绑定到asp.net文本框（带有母版页）
