calendarextender

问题 I'm using a CalendarExtender control with the help of <img> to populate a TextBox with a date. I am using this in EditItemTemplate of GridView . But when I click on the image, the calendar control is not poping up. I have used this CalendarExtender control in four or five other places (in this project) also. Everywhere else it is working fine. I have compared the code from the well working version to this code. No difference at all. I have written the code like below: <EditItemTemplate> <asp

问题 I have an <ajaxToolkit:CalendarExtender> object in my page. It puts the selected date on a disabled TextBox (populated at start with the today date). I would want a 'None' option in that calendar, for which the system would do a default operation (like it has the Today option). Is this possible? I searched information about this on the Internet, but I couldn't find anything relevant. I wonder if I missed something. Or do I have to implement a separate logic (like enabling the TextBox and the

问题 For some reason, any CalendarExtenders on an ASP.NET site that is being worked on will not be updated. I have already checked all the obvious places (such as AutoPostBack and AutoEventHandler). The problem is that when I select a date from the Calendar and post it to the form, the TextBox that is being extended IS being updated, but the calendar extender's date is simply not being being updated (e.g. SelectedDate is still the same as before). I have googled for any possible solutions but none

问题 I thought something like this <ajaxToolkit:CalendarExtender ID="TextBox1_CalendarExtender" runat="server" TargetControlID="txtDatumPoaganje" Format="MM/dd/yyyy" StartDate=<%=DateTime.Now%>> But it doesnt work. I can make something similar with JavaScript and alert message: how to disable previous dates in CalendarExtender control through its render event? but it's not the same. 回答1: Try SelectedDate instead of StartDate. Also, the link below says you can't set selecteddate from the html side,

问题 I'm trying to have a textbox function exactly like the third textbox down on this page: http://www.asp.net/AJAX/AjaxControlToolkit/Samples/MaskedEdit/MaskedEdit.aspx. I'm trying to use a CalendarExtender control with a MaskedEditExtender, because I don't want the user to be able to enter anything except a valid date into the box. On my maskededitextender I have a mask of "99/99/9999" but it seems to only work when the date is actually 8 digits (e.g. 12/12/2000) and not when the date is 7 or 6

问题 If you have used Calendar Extender, i am looking for ways to disable dates based on selection from another calendar selected date. In a project management application there are end and start dates, i am looking for ways to validate these on client. Someways would require postback which i am not willing to perform. There seems to be StartDate and EndDate properties for the calendar on the server, but does not seem to have any client side counterparts. Have you got any ideas how i can perform

问题 I'm trying to use Ajax Toolkit in ASP.NET page to display a Calendar Extender with this code, but it's not working for me. <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <div> <br /> <br /> <b>Calendar :</b><br /> <asp:TextBox ID="Date1" runat="server"></asp:TextBox> <asp:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="Date1"> </asp:CalendarExtender> </div> </form> It's not displaying the calendar.

问题 Can the calendar control be customsised so that, say you have a system of renting out a holiday home. can the dates that have been booked appear as red and disabled on the ajaxcalendar control? Cheers -- Jonesy 回答1: Run forest - run away from the ajax control toolkit. jQuery is your friend. Heres a link to the jquery Ui calendar. Other good plug-ins exists as well as other good javascript libraries, but MS is getting behind jQuery and jQuery UI is the official UI library. http://jqueryui.com

问题 I am trying to insert into a database - various details about an event. The asp.net textbox is using the Calendar Extender (so a little calendar pops up and fills the textbox with a correctly formatted date). The EventDate field in my Access database is of the type Date/Time. I need to convert the text/string to date/time format I have tried this so far: VB: Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim oleDbConn As New OleDb.OleDbConnection

问题 On an ASP.NET page, I have a pair of CalendarExtender (AJAX Control Toolkit for ASP.NET 4.0) controls on a page acting as a date range. What I want to do is, after the user has selected the value for TextCheckInDate , populate TextCheckOutDate with TextCheckInDate+ 1 if TextCheckOutDate is empty. Regrettably, my jQuery skills aren't yet where I'd like them to be. I know that I have to create a jQuery function that's fired when TextCheckInDate changes, I need to be able to read both textboxes,
