Question

How to get the calendarextender selecteddate value?

Asked by: aslyas

I have a calendar extender that have as a targetcontrolid a textbox.
When the page is loaded I assign the current date to the calendar and it updates to the textbox.

I select another date in  the calendar and it is updated also in the textbox, but when I try to take the value from the textbox or from the calendar(calendar.selectedDate) they give me the first date assigned when the page was first loaded, although the they show the selected.
This is the code:
<asp:TextBox runat="server" ID="txtDate" CssClass="TextGen" Height ="15px" Width="80px" />
<asp:ImageButton runat="server" ID="Image1" ImageUrl="~/Images/Calendar_scheduleHS.png" /><br />
<cc1:CalendarExtender ID="calDate" runat="server" TargetControlID="txtDate"
PopupButtonID="Image1" PopupPosition="TopLeft" Enabled="True" Format="dd/MMM/yyyy" />

Here    the current date is assigned in page_load
Dim defaultdate As New Date(year, month, day)
calFechaInicioOp.SelectedDate = defaultdate

I try to get its value:
varDate = calFechaInicioOp.SelectedDate.Value.Date  'calFechaInicioOp.SelectedDate.Value.Date
and it give the firstdate not the updated, same happens if I use the textbox,

They looks updated in the page, but their real value is the first assigned.

Thanks for your help.

Is it located in an updatePanel?

 

by: aslyasPosted on 2008-06-05 at 19:18:02ID: 21725727

No, it isn't.

 

by: naspinskiPosted on 2008-06-05 at 19:21:38ID: 21725744

Put it inside one and give it a try.

How can I use the updatepanel?

Since it doesn't appear directly, that means if I look for <asp:Updatepanel .... it is not found ?
Or how it does work?

Thanks.

 

by: naspinskiPosted on 2008-06-09 at 12:08:51ID: 21745724

make sure you have a script manager on the page
<asp:ScriptManager id="sm" runat="sever" />
<asp:UpdatePanel id="up" runat="server">
  <ContentTemplate>
    your stuff here
  </contentTemplate>
</asp:UpdatePanel>

 

by: aslyasPosted on 2008-06-13 at 14:00:59ID: 21782748

I tryied with your suggestion and although the calendar looks updated its real value isn't.
I write:
<asp:UpdatePanel id="updFecha" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<td class="LabelGen">
<asp:Label ID="lblFechaOP" runat="server" Text="Fecha de inicio de operaciones:" style="left:0px; position:relative; top: -4px"></asp:Label>
</td>
<td class="TextGen">                                                            
<asp:TextBox runat="server" ID="txtFechaInicioOp" CssClass="TextGen" Height ="15px" Width="80px" Enabled ="False"/>
</td>
<td class="TextGen" style="position:static">
<asp:ImageButton runat="server" ID="Image1" ImageUrl="~/Images/Calendar_scheduleHS.png" AlternateText="Click para mostrar calendario" /><br />
<cc1:CalendarExtender ID="calFechaInicioOp" runat="server" TargetControlID="txtFechaInicioOp"
PopupButtonID="Image1" PopupPosition="TopLeft" Enabled="True" Format="dd/MMM/yyyy" />
 </td>
</ContentTemplate>
 </asp:UpdatePanel>
as I am using the tookscriptmanager it didn't allow to set another.

Before I call the date value of the callendar I write:
updFecha.Update()

But debugging its value it is not updated.

Is there something missing?

Thanks in advance!

And the calendar remains with the value assigned

I found the problem:
<asp:ImageButton runat="server" ID="Image1" ImageUrl="~/Images/Calendar_scheduleHS.png" AlternateText="Click para mostrar calendario" />

I must state in the imagebutton, causesvalidation = false and the textbox is updated.

Thanks!
