Error in RadManager Tool Tip

[Janni]

Hi Team,

I've implemented the RadManager Tool Tip by the guide of this  http://demos.telerik.com/aspnet-ajax/scheduler/examples/radtooltip/defaultcs.aspx example.

I've implemented completely whatever you defined in that example.

Below is my code.

Hi Team,

I got the answer.
Just by split the rad scheduler value and passed to the tooltip.appointment.

Thanks
