I am using tigra calender in an asp.net page, but the datepicker will not show up. The img folder path is the same and i even placed it in my apdata. I took the code straight from the sample page, and I have even used tigra calender before, but not with asp.net any ideas. Is there another calender tool i should be using?

I've never used this product before, but it doesn't appear that the script references the correct control or form id.

We use a paid suite, but that code you posted sure looks wrong to me. Is that the whole thing? The script tag has no end tag, you can't start javascript statements with a "new" keyword, the input isn't marked runat=server and neither is the form...

I am adding a javascript CalendarExtender to a page,When I click the calendar button to trigger the calendar popup, the calendar displays normally. However, when I scroll down and click the button again, the calendar's position is display on top
