问题描述

我有一个使用ajax工具包的日历用户控件。

i我在两个日期字段（开始日期和结束日期）中两次使用gridview中的用户控件

我如何比较两个日期???



我尝试使用比较验证器，但它没有得到用户控件内的文本框ID 。



非常感谢一些想法..



谢谢



这是我的用户控件

I have a generic user control for calenders using ajax toolkit.
i am using the user control in a gridview twice for two date fields ("Start Date" and "End Date")
How do i compare the two dates???

I tried it using the compare validator but it doesnt get the textbox id which is inside the usercontrol.

Would appreciate some ideas..

Thanks

This is my user control

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="AjaxDatePicker.ascx.cs" Inherits="TCS.AjaxDatePicker" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
    </asp:ToolkitScriptManager>
<asp:TextBox ID="txtDatePicker" runat="server"></asp:TextBox>
<asp:CalendarExtender ID="calExtndDatePicker" TargetControlID="txtDatePicker"  

    runat="server">
</asp:CalendarExtender>

推荐答案

这是gridview中的比较验证器

this is compare validator inside gridview

<asp:comparevalidator id="CompareValidator1" runat="server" errormessage="CompareValidator" xmlns:asp="#unknown"></asp:comparevalidator>
            <asp:ajaxdatepicker id="UControl2" title="Date Picker" runat="server" xmlns:asp="#unknown"></asp:ajaxdatepicker>

这是设置控件以验证属性后面的代码

and this is my code behind for setting the control to validate property

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.DataRow)
           {
               AjaxDatePicker ajx = (AjaxDatePicker)e.Row.FindControl("UControl1");
               TextBox txtDatepicker = (TextBox)ajx.FindControl("txtDatePicker");
              // string id = txtDatepicker.UniqueID;
               AjaxDatePicker ajx1 = (AjaxDatePicker)e.Row.FindControl("UControl2");
               TextBox txtDatepicker1 = (TextBox)ajx.FindControl("txtDatePicker");
               //string id = txtDatepicker1.UniqueID;

               CompareValidator cmp = (CompareValidator)e.Row.FindControl("CompareValidator1");
               cmp.ControlToValidate = txtDatepicker1.UniqueID;
             //  string id=
           }
       }
