jquery的日期选择日期不结合在gridview的编辑/更新（与母版）asp.net文本框

Question

在下面的代码

，字符串sFoodFormReceived1总是得到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();   

}

    $(document).ready(function() 
     {$("input[id$='tbFoodFormReceivedEditItemTemplate']").datepicker();})

您可能想改为将代码中的文本框设置为datetime.now，而不是RowEditing。这样，绑定不会干涉。这可能是因为......

还，如果你这样做，你可能会得到更好的性能：

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

相反，所以你限制输入控件只在GridView，而不是整个页面。
