Thanks Sushant Pandey for reply,.I have try to tested datetime piker several times,and I compare it diferences run in IE 11 and orther Explorer can run right,.
then I just place a datetime picker on a mashup:
1、After clicked datetime picker widget,texts in widget should have a little move up and down, I guess it maybe cause to make opened panel closed.
2、The widget height became small than in other Explorer can run it right..
3、I run Thingworx and IE on Chinese language environment.
My IE version as below:
lianyi li - I checked this on Thingworx 8.0 (IE 11) and also on the previous version 7.4.2 (IE 11) .This widget is working in same fashion on both cases .On single click it's opening up and you just select the date and press done for close .This is how it's is designed .If you need some custom feature you may take a copy of this widget and try some hands on .
