I tried to put a drop down list in an update panel and then display the employee schedule in the calendar accordingly.
The calendar also has a DayPilotNavigator.
When I first hit the dropdown list, everything is right.
But the second time I select a different employee, I got the following javascript error.
And the DropDownList1_SelectedIndexChanged method no longer working.
I used the latest DayPilotProTrial-7.3.2841.
The problem is DayPilotNavigator .
It works fine without it.
DayPilotNavigator causes the javascript error when there is a update panel
You can put a break point at
int a =123;
to see the error
The following is my code with all the unnecessary removed.
