Calendar control is not popping-up when clicked on

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:TextBox ID="txtDateDelivered" runat="server" 
                 Text='<%# Bind("DateDelivered","{0:dd/MM/yy}") %>' 
                 CssClass="DateTextBoxInGridView" >
    </asp:TextBox>
    <asp:CalendarExtender ID="calexDateDelivered" runat="server" 
                          Format="dd/MM/yy" 
                          TargetControlID="txtDateDelivered"
                          PopupButtonID="calDateDelivered">
    </asp:CalendarExtender>
    <img src="Images/calendar.gif" 
         id="calDateDelivered" 
         alt="Calendar" />
</EditItemTemplate>

Can anybody please tell where could be the problem?

回答1:

how many row do you have in grid? also probably you have more than one image with such id

回答2:

The image tag which you have used is not a server control. It is simple html control, this is the reason why the calender control does not reconise this image control..

Try using asp.net image button over here instead of . It should work then.
