日历控制怀疑 [英] calendar control doubt

问题描述

Page1的场景



- 一个复选框

--fromdate和todate [都是日历控件]



- > fromdate和todate都来自日历控件

- >任务是：fromdate和todate都应该在启动时处于禁用模式。一旦我选中复选框，则应该启用fromdate和todate



------------------- page1.aspx --------------------

 <   tr  >  
 <   td    对齐  =  left    class   =  style2    colspan   =  4 >  
 <   asp：CheckBox     ID   =   chkroleid    runat   =  server   文本  = 为特定持续时间分配角色  
   
                                                           OnCheckedChanged   =  chkroleid_CheckedChanged    /  >

                                                           SetEnabled   =   false    /  >  
 <   / td  >  
 <   td     class   =  label    width   =  10％ >  
 <   asp：Label     ID   =  Label2    runat   =  server   文字  =  To Date  >  <   / asp：Label  >  
 <   / td  >  
 <   td     width   =  25％ >  
 < ;   uc3：CalendarControl     ID   =  txt_Appointment_To_Date    runat   =   server    ShowTime  < span class =code-keyword> =  true  
  < span class =code-attribute> 
                                                           SetEnabled   =   false    /  >  
 <   / td  >  
 <   / tr  >  

------------------------------- -------------------------------------------------- ----

SetEnabled =false



现在此功能在日历用户控件中声明如下



---------------------------------------- ------------------------------

  public   bool  SetEnabled 
 {
  get  
 {
  return   this  .txtCalendarValue.Enabled; 
} 
  set  
 {
  this  .txtCalendarValue .Enabled =  value ; 
  this  .hlnkCalLink.Enabled =  value ; 
} 
} 

- -------------------------------------------------- --------------------



如果我运行代码。



fromdate和todate都被禁用



-------------------- --------------复选框部分------------------------------

现在在page1.cs

  public   void  chkroleid_CheckedChanged（ object  sender，EventArgs e）
 {
  if （chkroleid.Checked）
 {
 
 txt_Appointment_From_Date.SetEnabled =  true ; 
 txt_Appointment_To_Date.SetEnabled =  true ; 
 
} 
  else  
 {
 txt_Appointment_From_Date.SetEnabled = 假; 
 txt_Appointment_To_Date.SetEnabled =  false ; 
 
} 
} 

- 现在如果我运行程序..我发现即使我检查或取消选中... fromdate和todate都被禁用....如果我把断点放在chkroleid_CheckedChanged ......调试器不会去那个复选框事件...



- 我在哪里做错了？请帮我解决这个问题。

解决方案

尝试为 AutoPostBack =True >复选框

Scenario of Page1

--one checkbox
--fromdate and todate [Both are calendar control]

-->both fromdate and todate are coming from calendar control
-->task is : both fromdate and todate should be in disabled mode in start. Once i check the checkbox both fromdate and todate should be enabled

-------------------page1.aspx--------------------

<tr>
                    <td align="left" class="style2" colspan="4">
                        <asp:CheckBox ID="chkroleid" runat="server" Text="Assign Role For Particular Duration"

                            OnCheckedChanged="chkroleid_CheckedChanged" />
                    </td>
                </tr>
                <tr id="FirstRow" runat="server">
                    <td class="lavel">
                        <asp:Label ID="ll_Appointment_Date" runat="server" Text="From Date"></asp:Label>
                    </td>
                    <td width="25%">
                        <uc3:CalendarControl ID="txt_Appointment_From_Date" runat="server" ShowTime="true"

                            SetEnabled="false" />
                    </td>
                    <td class="label" width="10%">
                        <asp:Label ID="Label2" runat="server" Text="To Date"></asp:Label>
                    </td>
                    <td width="25%">
                        <uc3:CalendarControl ID="txt_Appointment_To_Date" runat="server" ShowTime="true"

                            SetEnabled="false" />
                    </td>
                </tr>

-------------------------------------------------------------------------------------
SetEnabled="false"

now this function is declared in calendar user control as below

----------------------------------------------------------------------

public bool SetEnabled
       {
           get
           {
               return this.txtCalendarValue.Enabled;
           }
           set
           {
               this.txtCalendarValue.Enabled = value;
               this.hlnkCalLink.Enabled = value;
           }
       }

-----------------------------------------------------------------------

if i run the code.

both fromdate and todate are disabled

----------------------------------checkbox part------------------------------
now in page1.cs

public void chkroleid_CheckedChanged(object sender, EventArgs e)
    {
        if (chkroleid.Checked)
        {

            txt_Appointment_From_Date.SetEnabled = true;
            txt_Appointment_To_Date.SetEnabled = true;

        }
        else
        {
            txt_Appointment_From_Date.SetEnabled = false;
            txt_Appointment_To_Date.SetEnabled = false;

        }
    }

--now if i run the program.. i find that evenif i check or uncheck ...both fromdate and todate are disabled....and if i put breakpoint in chkroleid_CheckedChanged...the debugger is not going to that checkbox event...

--where i am doing wrong ? Kindly help me resolve this.

解决方案

Try setting AutoPostBack="True" for the CheckBox.
