hi team,
i have a Telerik Radchart. i have bound data for the Line series into that chart. i have enable the ShowItemToolTips="True" for the series and it was working fine.

Above that i have two custom grid lines. i need to have the tooltip service for the customgridlines. i have tried the ToolTipService.ToolTip="My Tooltip" but its not working. i guess the lines are not even focused. i cant raise the event when MouseEnter,MouseLeave and MouseLeftButtonDown. here is my code, Thanks in Advance
