RadTimePicker add hours with client side api

[Jacob]

How do I add hours to the current time on the RadTimePicker control?

Currently my 'End' RadTimePicker automatically defaults to the 'Start' time RadTimePicker when the user selects the Start time. My desired output is for the End RadTimePicker to automatically default the the Start time RadTimePicker, plus one hour, when the user selects the Start time.

Thanks for any help :)

Would it be possible for you to paste your code and a screen shot of your application. This would make it easier to understand your requirement and to help me to assist you.

function radStartTime_OnDateSelected(pickerInstance, args)
{
     var radStartTimePicker = $find('<%= radStartTime.ClientID%>');
     var radEndTimePicker = $find('<%= radEndTime.ClientID%>');
     radEndTimePicker.set_selectedDate(radStartTimePicker.get_selectedDate());
}

Hello Jacob,

The get_selectedDate is returning a Date JavaScript object so you could use it's functions to manipulate it.
For example you could use setHours to add one more hour.

currentDateTime = $find("<%= radStartTime.ClientID%>").get_selectedDate();
nextDateTime = new Date(currentDateTime);
nextDateTime.setHours(currentDateTime.getHours() + 1);
radEndTimePicker.set_selectedDate(nextDateTime);

Note that you will need additional check if the current hour is 23.

There are other solutions as well, please check this forum:
