Hi!
For example I have 10 textbox on my page. I created a panel with a calendar inside. I use 10 PopupControlExtender to bound the same panel to every textbox. (i dont want to create 10 diffrent Panels!)
And now i have a problem: How can i found out which PopupcontrolExtener and/or Textbox opend the calendar? I need this to set the value.
Any idea?
Thank you and sorry for bad english ;-)
Make it a user control. I've already done this and other than the issues that I've noted in some other posts about the popup behavior no longer working after postback, it works just fine. Below is the code I use to create the UserControl.
<%@. Control Language="C#" AutoEventWireup="true" CodeFile="DatePicker.ascx.cs" Inherits="User_Controls_DatePicker" %>
<asp:TextBox ID="tbDateSelected" runat="server" SkinID="DateTextBox"></asp:TextBox>
<asp:Panel ID="Panel1" runat="server" CssClass="popupControl">
<aspAjax:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<center>
<asp:Calendar ID="Calendar1" runat="server" BackColor="White" BorderColor="#999999"
CellPadding="1" DayNameFormat="Shortest" Font-Names="Verdana" Font-Size="8pt"
ForeColor="Black" Width="160px" OnSelectionChanged="Calendar1_SelectionChanged">
<SelectedDayStyle BackColor="#666666" Font-Bold="True" ForeColor="White" />
<TodayDayStyle BackColor="#CCCCCC" ForeColor="Black" />
<SelectorStyle BackColor="#CCCCCC" />
<WeekendDayStyle BackColor="#FFFFCC" />
<OtherMonthDayStyle ForeColor="#808080" />
<NextPrevStyle VerticalAlign="Bottom" />
<DayHeaderStyle BackColor="#CCCCCC" Font-Bold="True" Font-Size="7pt" />
<TitleStyle BackColor="#999999" BorderColor="Black" Font-Bold="True" />
</asp:Calendar>
<asp:ImageButton ID="imgCancel" runat="server" ImageUrl="../images/close.gif" OnClick="imgCancel_Click" />
</center>
</ContentTemplate>
</aspAjax:UpdatePanel>
</asp:Panel>
<ajaxToolkit:PopupControlExtender ID="pceDate" runat="server" PopupControlID="Panel1" TargetControlID="tbDateSelected" Position="Bottom" ></ajaxToolkit:PopupControlExtender>
<ajaxToolkit:DropShadowExtender ID="DropShadowExtender1" runat="server" TargetControlID="Panel1" Radius="6" Opacity="1" TrackPosition="true" Width="5">
</ajaxToolkit:DropShadowExtender

{
pceDate.Commit( Calendar1.SelectedDate.ToShortDateString( ) );
}
protected void imgCancel_Click( object sender, ImageClickEventArgs e )
{
pceDate.Cancel( );
}
}
Hope this helps.

You can find out which PopupControlExtender called the calendar with the info accessible by calling this following function, in the event handler for the control you popped up:
AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page)You can use that in, say, your calendar's OnSelectedDateChanged event handler to see where it needs to go.
You can use the .Commit() function to submit the information from the calendar to the correct control. Once again, this would go in the event handler for your calendar's OnSelectedDateChanged event handler.
AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page).Commit(Calendar1.SelectedDate.toString())Thanks toTed Glaza for the assist.
Hello!
Thanks for your reply!

Thats not the right solution. I dont want to deliver 10 rendered controls (With the same content!) to the client. Thats to much overhead!

Hi! That sounds interessting. But I dont get the point.
Protected Sub Calender_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim currentPopupControlExtender as AjaxControlToolkit.PopupControlExtender = AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page)
currentPopupControlExtender.Commit(DirectCast(sender, Calendar).SelectedDate)
End Sub
Is this what you mean? I will try it tomorrow!

Use
AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page).TargetControlID
to find the TargetControlID of the PopupControlExtender that caused the panel to pop up. In other words, what textbox is the target of the PopupControlExtender.
Is that what you are looking for?
Matt you are the man!
Protected
Sub Calender_SelectionChanged(ByVal senderAsObject,ByVal eAs System.EventArgs)AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(
Me).Commit(DirectCast(sender, Calendar).SelectedDate)EndSubThis work like a charme! I could use the Same "DatePickerPanel" on my page many times without duplicate code. Just add a Extender to the textbox and I'm done! Fine!
Thanks again for sharing this!
I am not sure that this actually works. I mean, the commit on the proxy works, but if I try to retrieve the value of TargetControlID from AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page).TargetControlID, it is null (which sense since what is returned from the getproxy method is an empty popupcontrolextender)
Is there any way to retrieve this information? I am trying to set the value of two textboxes, each based on the other and another arbittrary value...
i.e. - i would like my code to be soomething like:
AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page).Commit(calendar1.selecteddate.tostring())
select case AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page).TargetControlID
case "text1"
text2.text=format(calendar1.selecteddate.addmonths(arbitrary value),"MM/dd/yyyy")
case "text2"
text1.text=format(calendar1.selecteddate.addmonths(-1*arbitrary value),"MM/dd/yyyy")
end select
Could you pleaseopen a work item to report and track this issue. Thank you!
